Notes:

  • Vehicles with certain late model European tow packages may require the use of a tester (TR20117 - sold separately) or another truck or SUV to pair the receiver and transmitter.
  • The Prodigy RF cannot be submerged in water.
  • The Prodigy RF is not compatible with electric over hydraulic brakes.
  • The Prodigy RF cannot distinguish between hazard lights and brake lights. If you turn on your vehicle's hazard lights while towing with this controller, your trailer brakes will pulse.


Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner. Just set the initial power level, select a boost setting, and you're good to go.


As long as the Prodigy RF controller is mounted correctly, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.


Wireless, Radio Frequency Transmission for Portability

The Prodigy RF is perfect for anyone who has multiple tow vehicles. There's no hardwiring necessary. Just plug the 7-way lead on the control module into your vehicle's 7-way connector and plug the 7-way on your trailer into the port at the rear of the RF so that the braking signal can be transmitted from your vehicle to your trailer. Then plug the remote into your vehicle's standard 12-volt accessory outlet and use it to control the module wirelessly.


Because you don't have to wire the Prodigy RF to your vehicle, the trailer that you mount the module to can be easily shared among multiple tow vehicles. As long as your vehicle has a 7-way connector, you can use the Prodigy RF. This system is also compatible with vehicles that have multiplex wiring systems precisely because it does not wire into your vehicle.


Power Boost for Heavy-Duty Towing

Aside from smoother, more efficient braking, Tekonsha's Prodigy RF brake controller also offers a boost feature that gives you more initial braking power for those times when you're towing heavy loads. You can switch boost levels so that the power output to your trailer brakes automatically starts out at either 13 percent or 25 percent of the predetermined power setting.


So, if you boost the initial power so that your trailer brakes activate with 25 percent of the overall intensity at the start, the brakes will reach maximum braking faster. This is particularly beneficial if you are towing a heavy load because the intensity required to stop that load may be far greater than that needed to halt your vehicle. Therefore, sending out more initial power to the trailer brakes - and causing them to reach maximum braking faster - allows you to better control the trailer so that it doesn't push your tow vehicle before coming to a complete stop.


If your trailer weighs less than your tow vehicle, no boost is needed. But if you wish to set the boost so that your trailer leads the braking of your towing setup, you can select level B1. The following table gives an indication of when you might use the different boost levels and the power increases that they offer.


Approximate Gross Trailer WeightBoost LevelIncrease in Initial Power Output
Less than tow vehicleGVWB113%
Equal to tow vehicleGVWB1 or B213% or 25%
Up to 25% more than tow vehicleGVWB2 or B325%
Up to 40% more than tow vehicleGVWB325%

Both B2 and B3 offer a 25-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.


Safety Features

The Prodigy RF offers advanced safety features to prevent damage to various components of your towing setup. In addition to basic troubleshooting, this controller works to prevent problems before they begin. When the Prodigy RF is not in use, it will be in power-saving mode. If there has been no activity for 2 hours, then the system will go into sleep mode. Both of these modes are designed to drop the power draw, minimizing drain on your vehicle's battery.


When you stop at red lights, or any time that your truck and trailer are at a standstill with the brakes applied for more than 5 seconds, the Prodigy's "hold" feature will activate. When this happens, the power output to your trailer's brakes will be reduced to just 25 percent of the preset power setting so that the brakes will not overheat.


If ever there is a time that you need to brake your trailer separately from your tow vehicle - when traveling down a steep incline, for example - the manual override button is easily accessible on the remote control. Pushing this button engages the brakes on your trailer with full power. In addition, when you activate this override, the brake lights on your trailer will illuminate, properly warning those behind you of the braking action of your rig.


In addition to all of those safety features listed above, the RF offers diagnostics such as:

  • Open ground
  • Overload
  • Output short
  • Power loss
  • No trailer connection

Automatic Leveling and Simple Installation

The self-leveling feature of the Prodigy RF ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount the power module, which contains the inertia sensor, on your trailer tongue or frame as indicated. Some drilling may be required.


Correct Prodigy RF mounting

Note: The Prodigy RF must be mounted within ± 5 degrees of level on the horizontal plane and must be lined up so that the power cable extends toward the tow vehicle for the internal sensor to function properly.


Once the power module is mounted on your trailer and connected to your vehicle, simply sync up the handheld remote to the module as per the included instructions. Then plug the remote into any 12-volt auxiliary outlet in your tow vehicle for power.


Installation Accessories

See etrailer.com's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.

Video Transcript for Tekonsha Brake Controller - Proportional Controller - 90250 Review

Today we'll be reviewing part number 90250. This is the Tekonsha Prodigy RF Wireless Trailer Brake Controller for 1- to 3-axle trailers. This is a proportional brake controller so this controller is going to activate your trailer brakes in proportion to your vehicle's braking action. It will automatically adjust the trailer's braking based on deceleration of the tow vehicle. It's going to activate immediately so there's not going to be any pausing like when using time-delayed brake controllers. The wireless system is going to be perfect for shared trailers or if you're traveling in fleets. It's going to come with a remote control that's going to let you operate the trailer-mounted power module from the cab of any vehicle. All you have to do is program that per the instructions. This system right here has automatic leveling ability.

It's got an internal sensor that detects deceleration even if the controller is not mounted flat. It's really great for when going up and down hills. That automatic leveling is just a great feature to have. All you've got to do is position this within plus or minus 5 degrees of level on the horizontal plane. The system is going to offer three boost levels. It's going to let you adjust initial braking power and aggressiveness.

It also offers continuous diagnostic check that will alert you to any potential problems. It's going to feature integrated safeguards to protect your vehicle and trailer. It's going to minimize drain on your car battery when not in use and it prevents trailer brakes from overheating by reducing the power output to them during prolonged stops. Here on the remote it's going to feature a nice digital disk play that's going to be easy to read. You're going to have a manual override button. You're going to have your boost button and you're going to have your power adjustment wheel there on the side.

No hard wiring is necessary for installation. The 7-pole connector, which would be sold separately on your trailer, is going to plug into the 7-way socket on the rear of the power module which is going to be this portion here. It has that nice spring-loaded cap so it's going to protect those connection points. The wire lead on the power module is going to plug into your tow vehicle's 7-way connector, so this portion here. When mounting this on your trailer frame, you want to make sure that the power lead, that are cable or our wires, are mounted a way that's going to allow it to face the vehicle. That is going to assure us that this is mounted in the correct position. The remote control is going to plug into your standard 12-volt accessory outlet inside your vehicle.

This is also compatible with tow vehicles that have multiplex wiring systems. It's designed to work with trailers with up to 3 axles or 6 brake assemblies. Let's go over a few measurements. The power module dimensions from edge to edge here of the mounting bracket, it's going to give us a measurement of around 11 inches by about 4-1/2 inches. Then in overall height, it's going to give us a measurement of about 4-1/4. It's going offer a frequency of 3.2 GHz and mounting, you want to do this above or on the side of your trailer's frame rail, again within plus or minus 5 degree of level on the horizontal plane. It's going to come with the hardware that you need so you get this securely mounted to your frame. The dimensions that we have between our mounting holes, so measuring from the center of one to the center of the other, it's going to measure 9-7/8 of an inch. If we measure this direction center on center, it's going to give us a measurement right at 2 inches. Please note that vehicles with LED tail lights may not supply enough voltage for pairing so what you can do is you can use another truck or SUV to pair the receiver and transmitter. Please also note that the Prodigy RF cannot be submerged or immersed in water. That's going to do it for today's review of part number 90250. This is the Tekonsha Prodigy RF Wireless Trailer Brake Controller. .

Works great. Towing a 32' triple axle enclosed trailer behind a 37' motorhome. The wiring on the trailer was very simple, and just a couple of changes to the motorhome connector. First trip from NC to KS through the mountains in WV never had to touch the controller. Left the setting on the lowest setting (-B1) and the trailer never encountered any braking issues. It's also great if we tow the trailer with the pick up, just pull the controller out of the cig lighter and swap movers. 658121

I got this for my Toyota Tacoma. It doesn’t have a lot of room to add brake controller. I use it to tow an aluminum horse trailer. This product was easy to install and is very easy to use. it works consistently. I had the guys that I bought my horse trailer from also install a deep cycle battery and power port battery box. So I Use the box to hold the trailer’s factory electrical cord for when I’m using this one. And vice versa. I love it. 540447


Comments

It’s been about a year and I still love this set up. Set up is quick and easy every time. It takes no more time that a built in controller. My Tacoma has limited places to hardwire a controller. This is a fantastic option. I have also carried the controller to a F150 and Chevy to tow the same trailer. Worked great!

Works great. But trailer brakes activate and pulse on and off when emergency flashers (4 way flashers) are activated. However, very easy to set up, program and use. 619657

This is the 2nd Tekonsha Wireless Controller I purchased and have been fairly happy with the performance of both. One concern, and the reason I didn't give it 5 stars is that the hand controller cord deteriorates with heat. The protective plastic around the coiled wire dries out and crumbles. The replacement controllers are very expensive. One suggestion is to make the hand-help controller a little more ergonomic so it's easier to hold and operate. 606625

Everything everybody said it would be! Got it on time...we asked for special delivery as we were about to go on a trip...we hooked the RF up to our 02 escalade for pairing (once) and then to our 2011 Touareg TDI and our 25 ft Airstream for a flawless enjoyable trip to Verde Valley AZ and back to Seal Beach,Ca. E-Trailer is great !!! 151002

Still works great...after switching vehicles and trailers a couple times I think we will have to re-pair it again...will know in a coulple months when we use the airstream again.

Even as a former auto tech, I was a little apprehensive about “if” this was going to work as stated, especially with traveling 2 hrs to pick up our travel trailer from a dealer after converting our SUV from 4-pin to 7-pin and unable to test the trailer brakes until we got there. I was thrilled to see all the claims were true as it immediately “connected wirelessly” after mounting to the frame and following the Pairing instructions to our RX450h! I could have done as the video shows and shorten the trailer connection, but if I trade this camper for another, you can bet this brake controller is going WITH me! 507801

2017 Porsche Macan

I own a 2017 Porsche Macan GTS with a factory hitch and factory installed trailer wiring. I decided to go with the Tekonsha prodigy RF unit because Porsche hides the end of the wiring harness in the dashboard for the brake controller. Two dealers that I brought my car to said that they would need to remove most of the dash to find it, "German Engineering". I did a lot of research on the compatibility of this unit for my car and this is what you will need to get this unit to pair correctly. You will need a Tow Ready 20142 7-Way Flat Pin to 7-Flat Pin Adapter with LED Lamp Out By-Pass for European Vehicles . Unless you have this adapter the car will not recognize the RF unit. Once I used the adapter the unit paired immediately. This is the only way you will get it to pair correctly without using another vehicle to complete the pairing process. You will also need this adapter when you tow your trailer. I wish someone else had posted this for me. I spent many, many hours figuring this one out. 452721

Excellent product. Used with 2011 MB GL350 BlueTec pulling a 2104 Keystone Passport Ultralite 23 RB w/electric brakes. Very easy to install. One drawback - must sync brake controller unit via an American vehicle. This is something most trailer dealerships do not know! Once sync'd via an American vehicle, works great with MB w/o any issues. Recommend all MB owners consider using this product with trailers utilizing electric brakes until a better product comes onto the market or until MB 1) engineer their vehicles and/or vehicle computer system to flawlessly interact with after market brake controllers, or 2) develop a brake controller for exclusive use with MB vehicles equipped with towing hitches. At the time of this posting, the cost of this brake controller unit is far less that what MB charges to install/hard wire a brake controller unit for trailer towing! Again, excellent product. 99273

My son just purchased a fifth wheel and needed a Tekonsha Prodigy RF Trailer Brake Controller (order 90250). Looking at the mechanics shops around town and at auto supply retail stores, we had no luck. Then we lucked into etrailer.com during an online search and our frustration ENDED. Yahoo. Found the correct item, found also that it was less expensive at etrailer.com and, as I am technologically challenged and needed it fast, I called etrailer.com's telephone line. I got a lovely sales rep who confirmed with me that I was ordering the right part for the vehicle and got me overnight delivery.... which was really overnight delivery. All the way to Bonners Ferry, Idaho! Love the shipping tracking that etrailer.com sent with the confirmation to my email address, it made it super easy to follow. I could not be happier and will never shop at any other site but etrailer.com for our RV. Thank you so very much 215983

First of all I want to start out the review by saying I was a bit skeptical of this website. I had never heard of it before, but the ease of finding what I needed was so great that I decided it was worth the try. I was in search of a wireless brake controller for my truck. This is the only place that I found it and could get it within the week. I ordered on a Monday (Memorial Day) and everything seemed to go through okay until I got an email my payment was declined due to address error. I decided to call since they had already taken the payment out and this is where the review gets great. I got in touch with a guy named Darren who helped me understand what had happened. He told me there system had been down for maintenance and they couldn’t put the order back in but he would give me a call when they could. He stuck to his word and called me back. We were able to get the problem solved easily and promptly. My product came on time Thursday and there was no issues with it what so ever. The only thing I could say is watch the boxes when you get them, the bottom of mine fell out as I was picking it up, thank goodness that didn’t happen before it was delivered! I definitely would recommend this website to anyone 516823

Install was not to bad at all, it would not pair with my Tahoe but it paired right up with my 4 runner. Great company to deal with 553730


Comments

Id first check that the 12-volt feed and turn signal pins on the 7-way on the Tahoe are functional. Then, you can pair the unit with the 4-Runner, and it should work on the Tahoe. Plug the RF into the 7-way of the 4-Runner, but dont plug the trailer into the RF yet. Plug the remote into the cigarette lighter port of the 4-Runner and set the gain to minimum by rolling the power wheel toward the cord. The display might show NC, not the 0.0 per the instructions. Press and hold the boost and manual buttons at the same time, the display will start counting down from P5 down to PA. When the display reads PA, release both buttons and apply the brake pedal within one second. The display should change to a flashing 0.0, at which time the control will be paired. At this point, plug the RF into the Tahoe, the trailer into the RF, and move the remote from the 4-Runner into the Tahoe. You should only need to do this once.

Bought for my diesel pusher to avoid the headache of running wiring about 36'. Have used on two trailers (enclosed for dune buggy, tandem axle for Jeep) by mounting for easy transfer, and have experienced zero problems. Easy install (follow directions for easy connectivity - once established, never have to do the procedure again). Trailer box is splash proof, and the hand held device is easy to operate for additional "hard" braking if needed. Would buy again in a minute if needed, and don't hesitate to recommend to others, especially for application cited. 272024


Comments

still lovin it - matter of fact, using it right now with tandem axle trlr. from Mar to Oct, use for a couple weeks each mo with zero probs, including transferring between two different trailers. Great investment that saved a lot of time and headache on initial install.recommended especially for those with a long think Motorhome tow vehicle to avoid wiring issues. Works great with a diesel pusher even tho the wireless receiver behind large mass of coach, engine,transmission, etc.great value!

I just got this yesterday (was delivered as promised) and will be installing it tomorrow (Saturday). Looks easy to install! This will solve the problem of hard wiring a controller to a Mercedes ML350. Hard wiring would take many hours and lots of effort . Wireless should be quick and clean install. 179939

I ended up not being able to use this unit. I mounted the box on the trailer per instructionsbut had to modify the mounting brackets cut one end off inorder to barely fit the box in the space available on the trailer. After fabricating a new bracketI could never get the braking to work properly. Pairing was no problemI used a different tow vehicle per some comments on forums. the problem was that the unit would cause severe jerking of the brakes no matter how I adjusted the unit. I ended up having to pay somebody it is a very tricky install to install a traditional prodigy unitand it works great.Over many years I have installed and used over 25 trailer brakes units on everything from cars , trucks, suvs ,1 ton tow vehicles, and RVsthis is the first time for a problem. The ML350 is a 2013 with the factory hitchtow package. The trailer in question is a 2014 Airstream 20 FC.

I recently purchased a Teardrop Trailer with no brakes. Legally it doesn't need brakes and many Teardrops don't have them, but a smaller one I rented before purchase was a little heavy going down into Death Valley from Panamint Springs, a pretty steep winding road. There isn't a lot to decide about brakes, but there are sure a lot of choices in controllers. I wanted proportional because that seemed like it would work better and pretty much everyone I meet with a Teardrop recommends them. I wanted wireless because Chrysler minivans with the tow package do not include braking wiring for some reason, and I own two. I wanted to be able to buy replacement remotes in case I lost one or just wanted an extra for the other car. I wanted a product with basically good reviews, and I read all of the poor reviews I could find to see if I'd be likely to have the same problems. I wanted a vendor with a competitive price but who has a good reputation and plenty of information about the product online. etrailer packaged it well and shipped it out the same day. They also emailed me links to product info such as installation videos. Altogether, I'm satisfied with both product and seller. Installation was a breeze. 1. Use self-tapping screws to install power module on frame right side up. 2. Plug trailer pigtail into module. 3. Plug module pigtail into car. 4. Plug remote into 12v socket in dash. 5 Follow instructions to pair them, a matter of holding down two buttons for a short time while also depressing the brake. 6. Set initial adjustment at about the middle then use, and adjust up or down to suit. Many negative reviews about this controller talk about having trouble pairing the two parts. I had absolutely no trouble, it paired in maybe 10 seconds or so. Adjusting the brakes just so will take a while. I spent maybe 5 minutes getting them close but will see how they handle in a variety of situations next week for finer tuning. It is easy to change the adjustment for different conditions, for instance slippery roads or going down a steep hill or adding a few hundred pounds to the trailer. 453534

2003 Pontiac Montana

The main reason I bought this unit is for the remote hand held control. I had a bad experience 40 years ago with a trailer fishtailing behind me going down a mountain in Montana that could have easily been controlled if I could have applied the brakes to the trailer only. My first brake controller was a time delayed unit I bought from etrailer in 2003 and it was the only one I could find with a handheld unit I could mount anywhere on the dash. It worked fine and would apply the brakes to whatever maximum setting I had set for it every time my pickup brakes were applied. This proportional controller is more expensive than I wanted, but it was the only one I could find with the remote handheld unit and it does just what I wanted. It doesn't apply the brakes to the maximum everytime like I am used to, but I assume it is applying it as much as needed. But what is great about it, if I want to apply the brakes to the maximum, the handheld unit is within easy reach and can be applied immediately. So, even though it is more expensive than what I wanted to pay, it gives me exactly what I wanted in being easy to quickly reach and apply just the trailer brakes if needed. I waited on writing this review until after I completed a 550 mile trip thru some large cities with heavy traffic and I am very satisfied with my purchase of the Tekonsha Prodigy RF brake controller. 121855

Still satisfied. Between the time delayed unit and the proportional controller, I personally like the time delayed unit, but this one is fine.

I have used this brake controller while towing a travel trailer with a 2013 Mercedes ML350 Bluetec. Overall I am satisfied with the performance of the brake controller but do have one complaint. Being that the electronics of the controller are mounted on the trailer, it tends to create a rapid series of brake applications during one braking event. I'm guessing it is due to some sort of feedback. This doesn't happen all the time but it does happen occasionally. I've worked around it by using the manual control quite a lot. I've learned to use the manual control pretty smoothly but still have automatic brake operation whenever necessary. With a little practice, manual operation is quite smooth and not much of a bother. Be aware that the manual control does not activate the brake lights on the trailer by itself. You still need to apply tow vehicle brakes for the trailer's brake lights to activate. I have used this brake controller using the same trailer but with another tow vehicle. It worked first time, exactly as it does with the Mercedes. 376903

Very pleased with this product. We installed on a Livin' Lite aluminum frame (ended up drilling into the frame as described but purchased stainless steel screws instead of the ones that came with this product). Our vehicle is a 2014 Toyota Highlander. We didn't get the correct display according to the manual when trying to synch and called etrailer for support. The operator couldn't help us so put us in contact with the manufacturer who walked us through the synch with no issues. So happy to have this product without having to mount anything in our vehicle. Thank you e-trailer! 151086

2017 Ford Edge

So easy, so nice. My tow vehicle is a 2017 new model Chrysler Pacifica minivan. It had factory tow installed but my dealer could not locate a Tekonsha wiring harness. With a short deadline I took Ashley's advice and tried this Prodigy wireless controller. Installation was seamless and so far, this unit has worked flawless. It is nice to just stow the hand controller out of sight until I need it and it never fails to sync. Beyond basic operations, I was pleased to see this controller complimented my vehicle's trailer sway control. My new Pacifica is the first vehicle I have ever had with Trailer Sway Control and I already think, if you tow, it is a must have option on any new purchase. When I encountered trailer sway on a tight corner going down steep mountain grade in California using the brake controller was my only option as trying to just brake my vehicle might have just pushed me over the mountain edge. But before I could even reach for the remote or even understand the situation the controller engaged and instantly pulled the entire rig straight. That was some incredibly nice feeling. I was so impressed with this automatic braking that I called Prodigy to thank them but they explained that the controller only brakes in response to the vehicles braking so the main credit must go to Chrysler's Trailer Sway Control. Apparently the Pacifica had engaged some rear brake combination which in turn engaged the controller. But perhaps Prodigy still gets credit for smooth and proportional response. Prodigy Tech also assured me that this wireless unit was robust enough that it should not fail bar enclosing the controller or remote in metal shielding. 343482

System was painless to install. Instructions were straightforward. Most of the install time was spent drilling the mounting screws, which amounted to about fifteen minutes. Pairing the unit with my 2014 Chevy Express van was just a few more minutes. Hooked up the trailer and was on my way. I have only used the trailer a couple of times but am very satisfied with the unit. Stopping is very smooth. This unit was not very inexpensive. But I will be able to use it with other vehicles if the need arises and installation was trouble-free. 130358

We had to call the Mfg to figure out that cars with LED tail lights do not have the required voltage to pair it. The product worked fine on Mercedes after pairing with another vehicle 1st. If this is known to Mfg, I think they should just pair them at the factory to save customer a lot of time and effort. 68804


Comments

Aghrrr! I wished I would have read this sooner.... I just spent several hours trying to figure out why I could not pair it using my MLs tow setup which is set-up for LED. Now I know... Use a different car...I agree, units should be shipped already paired... Thanks Clint!

The reason why these are not paired at the factory is because the unit must establish the mounted and ride height position on the trailer. The LED lights on the vehicle isnt so much the issue. Some European vehicles send signals through the trailer plug for Lamp out or Trailer detection that can interfere with the pairing process, but once the trailer is detected these signals pose no issue.

Ive just purchased a Porsche Cayenne and am considering the Prodigy RF. It looks like I should expect problems with the pairing and may need to find an American vehicle for that process. Reading the statement of Pete D on 4 June though: The reason why these are not paired at the factory is because the unit must establish the mounted and ride height position on the trailer ... it sounds like pairing will be effected depending on vehicle specs relative to trailer specs? I.e, is it necessary to use an American vehicle with dimensions similar to the Cayenne? Thank you,

-- comment by: LynnSL - 10/03/2013

The accelerometer has to establish its zero on the trailer it is to be used with. So the process would go like so: 1) Couple the trailer to your Cayenne on a level surface. 2) Park the domestic where you can connect the trailer wiring to the domestic vehicle 7-way. 3) Follow the pairing procedure in the instructions. This method allows you to maintain the appropriate trailer ride height with your Cayenne while using a domestic vehicle for the electrical hook-up.

Ordered this about a year ago. Installed on trailer. Followed directions carefully. One year later it hasn't worked for single second, never. I went back and retried over and over, pulled everything out and started over and over again. At least three times. Called the company. Was told, "Well, it doesn't work right away with foreign vehicles." Gee, wish I knew that going in! So we tried it on a Ford PU, nope, nothing, no signal on the remote that suggested it was working. As of right now it's just sitting on the trailer collecting dust. Remote inside the vehicle. Just tried calling the 800 for service. Sat on hold for 20 minutes, finally gave up....it's 4 pm on a Saturday so perhaps the service dept is off for the weekend. Looks like another road trip with no trailer brake control. Paul d. 403197

Wow, What a device. My reasons for selecting the 90250 Prodigy RF was #1 I did not want to drill holes in the firewall of my brand new car. 2. Favorable customer reviews. 3. The compact size of the hand held unit. 4. I only had to run 1 wire from battery to 4 - 7 way plug (connected to Black wire or 1 o'clock position). I had learned that from one of E-trailers question and answer forums. Chelsea at E-trailer was awesome at answering my questions and helping me with my purchase. The installation was easy however I had to call tech support when it came time for pairing. I installed this on a 2016 Toyota Highlander with the factory 4 way wiring. I followed the instructions exactly however I never got the 0.0 flashing indication at the beginning of the pairing process. If this happens to you , skip this step and continue to the next step. I had no problem with the pairing after this. John from Cequent performance was great at providing Technical support and said they need to take that comment 0.0 flashing out of the instructions (see #6 in the pairing instructions.). He knew exactly what my problem was. I set my hand held to 6.0 when applying the manual override button. Took it for a test drive and It worked like a champ. I will be towing with it tomorrow. Thanks E-Trailer 345086


Comments

Still working great, I brag on it with my towing friends. When I am towing I keep the controller on my center console. If I need to manually brake , I dont even have to take my eyes off of the road, just reach over to the controller and apply the brakes. I do not know why I dont see more of these on trailers.

2015 Audi Q5

This is really an awesome product with one major flaw that will frustrate many.....the 'pairing' process. We had purchased a new 2015 Audi Q5 TDI, and did not want to rip the dash apart to get to the wires to install a brake controller....as well as mount the ugly controller somewhere in the cabin where we would hit it with our knees. Bingo, this product is perfect as almost everything is in a unit that mounts on the trailer tongue. Our trailer is small, 2,300lbs, and the unit seems to control the brakes well. But the 'paring' process is very frustrating. There is a small unit that is in the cabin that needs to be paired with the unit on the trailer. Sounds easy, but the instructions are wrong from step 1 (step 1 has you plug in the cabin unit and see '0.0', but my unit would only show 'n.c'...for 'not connected'). But after playing with many different combinations, I finally got the unit to pair. Now that the unit is 'paired', it stays paired, so all is good. I'd advise everybody to treat this step like a computer, where sometimes what you are trying to do keeps failing so you just keep attempting doing things slightly differently.....and all of the sudden it works. What they need are some indicator lights or a screen so one can help troubleshoot the process. Note that in my car, I had bought the 20142 trailer lamp out connector because others had said that the Audi would not pair without it (the Audi needs to see enough of a load on the circuits or it will shut off power to them). Turns on in my case the pairing would only work if I did *not* use the 20142. So who knows.... 172851

Volvo Cross Country

We purchased this unit for what probably would be a one-time use. But it was crucial that we have it and we still keep it in case we should ever need it again. The circumstances were that we wanted to pull a 4,700-pound camping trailer cross country (2 days, 1200 miles) with a rented 26-ft straight truck being used as a moving van. The Pickup that usually pulled the camper, that had the brake controller installed, was being used to pull a boat. We only had two drivers and only one with the confidence to operate the 26-ft truck. The other driver did not feel comfortable pulling the big camper behind the pickup. The 26-ft truck didn't have a brake controller but the camper is a dual axle with electric brakes. We installed the unit on the frame of the Camper and taped the power wire it to the side truck until it was able to be alligator-clipped to a positive battery post near the passenger door. We followed instructions carefully including adjusting the brakes properly. The trip was completed safely and we could tell the unit was working, and it worked flawlessly. 688540

Great product which worked well with our 2016 Tesla Model X. Unfortunately it doesn't work with our 2018 Tesla Model X. This is not the fault of the brake controller. Apparently Tesla changed the way they wire the 7 pin trailer connector in early 2018. It no longer supplies 12v to the AUX pin which is required for the wireless brake controller. We replaced this unit with the Prodigy P3 brake controller which works fine. 680779

The Tekonsha RF Wireless Brake Controller is a marvel of security and peace of mind. I was initially reluctant to spring for brakes and brake controller for a 1-ton capacity trailer.

No fear of a runaway load with this. I hardly knew there a was a trailer behind me! 667711

Bought this as my new Q7 had no good place to attach a regular brake controller. Reading reviews, I was leery as there were quite a few stories of not being able to pair the unit. There are also stories of the unit loosing its pairing. RV dealer installed it on the new trailer. I came to pick it up, followed the step by step instructions to the letter, even if they can seem counter intuitive. Our only confusion, the last instruction should be "take your foot off the brake" :-) The connection was made, the connection has held. The controller is smooth and flexible. Great product. Clean sleek dash in my new Audi Q7. Trailer tows perfectly. 664768

Very easy installation and setup pairing my trailer to my 2017 Honda Pilot. Follow the the instructions exactly and it works just like advertised. I selected this product because I did not have a good spot for a conventional controller in the cab of the Pilot and was not thrilled with the prospect of tearing into the factory wiring. Additionally, there was the issue of potentially towing this camper with other vehicles, and then needing to repeat the entire installation process. All of these concerns vanished with this unit. I'll be giving it rigorous testing on the road to AK later this summer. 659484

  • Both of the 2-inch Class III hitches we have for your 2012 BMW X5, Draw-Tite # 75600 and Curt # 13077, are fairly involved installations as hitches go. The linked video illustrates the installation of the Draw-Tite hitch on a 2012 X5. This hitch is rated for a maximum towing capacity of 6000-lbs but you will want to check your BMW owner's manual to confirm the towing capacity for your particular X5d as equipped from the factory. Engine and transmission options can affect a vehicle's towing...

  • Can Prodigy RF Brake Controller be Used with Tuson Electric Brake Sway Control System
  • You can use the Prodigy RF brake controller part # 90250 with the Tuson Electronic Sway Control System for Electric Trailer Brakes # 335TSC-1000 that you also referenced. Essentially the Tuson Control system detects trailer sway and then applies the trailer brakes in a way that is known to reduce the sway. If the # 90250 is also applying the brakes the Tuson would override the brakes and apply them harder if needed to stop the sway. With trailer sway if you apply just the trailer brakes...

  • Wireless Brake Controller Compatibility with 2014 Audi Q5
  • The Prodigy RF # 90250 can have serious issues pairing with European vehicles and while this used to be the only option to use a wireless brake controller, that isn't the case anymore so I recommend an alternative that isn't going to have the amount of potential headaches and extra cost associated with it like you would need with the RF and 7-way Adapter # C57003. So long as your 2014 Audi Q5 has the factory tow package the Curt Echo # C51180 will simply plug into the 7-way on the back...

  • Brake Controller Recommendation for a 2018 Toyota RAV4 XLE
  • Although a wireless brake controller like the Tekonsha Prodigy RF # 90250 is a great option to use for towing, since you will need to install the Universal Wiring Kit # ETBC7 anyways, I recommend going with a different brake controller. If you were to tow a different trailer that has brakes and a 7-Way you will need to uninstall the RF from your trailer and install it on the other trailer. If you use a brake controller that installs in your 2018 Toyota RAV4, the only time that you will...

  • Why Does Brake Controller Harness for 2018 Toyota Tacoma Have Ground Wire
  • That's a common question and the reason Wiring Adapter for Trailer Brake Controllers # 3031-P has a ground wire on it is because some models of Tacoma and Tundra, such as your 2018 Toyota Tacoma, have an insufficient ground at the factory connection and this adapter remedies that potential issue. While there is a wireless option, the Prodigy RF # 90250 I very strongly recommend going with the Prodigy P3 # 90195 which is a better option in every way. The P3 is easy to use, levels automatically,...

  • Brake Controller to Fit the Ford E450 Chassis of a 2017 Thor Axis Motorhome
  • The Prodigy P3 Brake Controller, # 90195, can be installed on your 2017 Thor Axis with Ford E-450 chassis. However, on the this particular motorhome, there is no plug and play wiring harness available. You will have to hardwire the brake controller into the cab of your Thor's coach and a 7-way connector at the rear. Although your Thor motorhome is built on the Ford E-450 chassis, Thor removed the dash and all the Ford installed electrical connections that would have allowed the brake...

  • Recommended Brake Controller For A 2017 Range Rover Sport
  • On your 2017 Range Rover Sport, the best option for a brake controller is the Tekonsha Prodigy RF Wireless Trailer Brake Controller - 1 to 3 Axles - Proportional # 90250. This will use a factory 7-way or aftermarket 7-way for proper function. If you have a factory 7-way, you can simply plug this brake controller into your trailer connector and mount it to your trailer and you will be ready to go. If you don't have a factory 7-way, you will need to start with a 4-way flat connection....

  • Prodigy RF or P2/P3 Comparison
  • Both RF- and wired-type proportional Prodigy brake controllers use an accelerometer to detect braking in the tow vehicle in order to send a proportional brake signal to the trailer brakes. Performance wise they would be identical. The P2 does have to be mounted facing a certain direction so that it can properly sense decoration though so you would need to consider that as well. The RF doesn't require any permanent modification to install though which is nice and the remote can easily...

  • Parts Needed to Install 7-Way Trailer Socket on 2015 BMW X5
  • The Draw-Tite # 75600 and Curt # 13077 are the confirmed hitch fits for your 2015 BMW X5 so long as it is not the M model; for that model we have no hitch. Both of these hitch items are fairly involved installations as hitches go; you can refer to the linked video for the Draw-Tite. For wiring, what you need depends on the trailer you intend to tow. For a basic aftermarket 4-pole harness that just carries trailer lighting signals (for a trailer with no brakes or other power requirements,...

  • Recommended Wiring When Adding 7-Way Trailer Connector To 2016 Ford Escape
  • First, I would recommend using part # 37185 instead of the # C57674 you mentioned because the test lamps on the connector can cause issues with the Tekonsha Prodigy RF Wireless Trailer Brake Controller, part # 90250. The best way to run the system is to connect the black wire from the # 37185 directly to the positive battery post for your 12V power on the 7-way. This prevents any issues with power draw and possibly performance problems with the lights on the trailer. I have attached...

  • Replacing Factory Brake Controller on 2018 Toyota Tundra
  • The problems you are having with the factory brake controller on your 2018 Toyota Tundra, as you mentioned, are not too uncommon. This is really the case with most factory brake controllers regardless of the truck make or model, as many customers choose to replace it with an aftermarket unit as soon as they get a chance. Before doing so I do recommend talking with a local Toyota dealer to see if anything needs to be done after unplugging the factory unit as it's possible the computer...

  • Parts Needed to Install Tekonsha Prodigy RF Brake Controller on 2014 BMW X5 with 4-Way Connector
  • To install the Tekonsha Prodigy RF Wireless Trailer Brake Controller # 90250 on your 2014 BMW X5 that is already equipped with a 4-Way, you will just need the Hopkins 4-Pole to 7-Pole Adapter # 37185, some 10 Gauge Wire # 10-1-1 (sold by the foot), and a 40 amp Circuit Breaker # 9510. To install these parts, you will simply plug your existing 4-Way into the 7-Way adapter, and then run the black wire from the adapter to the BMW's positive battery post with the 10 gauge wire through the...

  • How to Install a Brake Controller on a 2018 Toyota Highlander
  • I have the perfect option to add a 7-way and trailer brake controller to your 2018 Toyota Highlander and it will not require any splicing into the factory trailer light wiring so it will not void the warranty in regards to this aspect. For this, I recommend our Tekonsha Prodigy RF Wireless Trailer Brake Controller part # 90250 which installs on the trailer and does not require any modifications to the tow vehicle. It uses radio frequency and can easily be transferred to different tow vehicles. The...

  • How to Use the Tekonsha Prodigy Brake Controller Part # 90250 on a 2018 Volkswagen Atlas SEL
  • Yes, the Tekonsha Prodigy RF Wireless Trailer Brake Controller part # 90250 will work on your 2018 Volkswagen Atlas SEL as long as you have a 7-way trailer connector. If you do not already have a 7-way trailer connector then you are going to first need a 4-way trailer connector and then a 4 to 7-way trailer connector. For this, I recommend using the T-One Vehicle Wiring Harness part # 118754 with the Universal Installation Kit for Trailer Brake Controller part # ETBC7. Please note that...
