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 vehicle GVWB113%
Equal to tow vehicle GVWB1 or B213% or 25%
Up to 25% more than tow vehicle GVWB2 or B3*25%
Up to 40% more than tow vehicle GVWB3*25%

*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

Video Transcript for Tekonsha Brake 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. .

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

Comments

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

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.

Thanks for the clarification and information.

Patrick B - 6/5/2013

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.

I work at a Mercedes-Benz Dealer, if you use the 7 way to 7 way LED adapter curt C57003 your vehicle will recognize the unit and program without issue.

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

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

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

Hi Mark, No problems at all. knock on wood!!. Still love this controller - we keep the handheld device in the storage console of the Highlander and just plug it in and go when we pick up our camper from storage. It works great.

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

Hi Tom,How did the installation go? I have an 05 ML500 that needs a brake controller. What year is yours? Did you have any difficulty pairing the system as others have had?Thanks,Mike

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.

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.

Excellent product! Easy to install and works exactly as advertised. I installed on a dump trailer that I tow behind several vehicles -- none of which had an installed brake controller. This unit allowed me to purchase/install only one controller on the trailer and have the flexibility to use any tow vehicle I wanted. Once easily adjusted with the hand controller that plugs into a DC power outlet, it is hands-off automatic operation. I was initially concerned that using the hand controller to manually override the unit would be more difficult than with a unit mounted to the vehicle dash, but I quickly discovered the exact opposite to be true. Not only is the hand controller easier to use, it provides a digital indication of the power being applied. An added benefit is I don't have a permanently installed controller cluttering up the leg space of my vehicles. I love this setup so much now that I would go this route (trailer mounted controller) even if I didn't have multiple tow vehicles. Definitely recommend this product. I can also enthusiastically recommend etrailer.com as a vendor. Extensive selection, fair prices, incredibly fast delivery, and unmatched customer service make them a pleasure to deal with. My 'go to' for anything to do with trailers! 250836

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

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

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.

Easy installation and once I got it paired via another vehicle (when I bought the unit a week ago, you gave me a heads up on probable trouble shooting) it worked in my new Mercedes. I took it for a test drive, adjusted the controls a little and it worked like a champ. Great product and fine service. Thank you. 96890

Impressed with the product. Installed it on a single-axle utility trailer and have had no issues with it. It's important to understand that this operates differently from a traditional brake controller. Unlike a traditional controller it doesn't have a line to the brake switch, it has to infer brake operation by both the left and right signal wires getting voltage at the same time, like if you're on the brakes. Things get fuzzy when you brake first and then set a turn signal, as the controller gets confused and can sometimes apply the brakes on and off with your blinker flashers. The guts of the system are mounted on the tongue, the control module in the cab is only used to tell the module of your inputs. If the handheld becomes disconnected or loses power, the controller will still function with the last known settings. I'm very happy with the controller so far, it's been reliable and consistent without me having to run wires through the dash. 248485

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

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

Little tricky getting it set up on our VW Touareg. Reason being it has a smart towing circuit that is a little more complicated than most cars. Had to use a different carFord Expedition to get the unit to pair up, but after that it works great on the Touareg! Word of advice, make sure your tow vehicle has the trailer battery charging circuit enabled in your fuse box. The Expedition was missing this charging circuit relay in the fuse boxhad a spot for it, just wasnt factory installed so once we got a relay for it and a little 30amp fuse that was also not present, setup was super easy. My favorite part is how the system is accelerometer based so when you are not moving fast or not at an angle , it knows to dial down the brakes so you dont jerk the trailer around. Touareg drove like our 5k lb trailer wasnt even there. Then again the turbo diesel motor doesnt hurt either 77218

This unit was to have eliminated the need to run a brake line from a controller in the cab to the 7-way connector at the hitch. I wish it would have worked out--I should have paid more attention to the size of this unit. It's much larger than an in-cab unit. So large that I could not find a suitable mounting location on my teardrop camping trailer. The big limiting factor is that the cover stands up from the body about an inch. Since my trailer frame is about as tall as the mounting bracket, mounting the controller to the frame means you must have another inch of clear space above the unit. Due to cargo boxes installed on the tongue of my trailer, I don't have that headroom above the top of the trailer frame. I will have to return it in favor of an in-cab mounted controller. 147121

The ONLY way to tow with a Mercedes GL350...easy to install after scanning the E Trailer video. Not sure why it wasn't already "paired" with transmitter at the factory...but that was pretty easy to initiate. Has worked flawlessly for the last year. Somewhat pricey, but really the only alternative for German vehicles. Highly recommend. 240308

I know a lot of folks said they had to pair it using an American tow vehicle first, but I did not. It quickly paired with the MB but the accompanying directions must be followed precisely.Good luck...great to see another GL Blutek hauling...we are really happy with it as a tow vehicle...pulls our 25 ft Airstream effortlessly.

Tekonsha Prodigy RF Wireless works exceedingly well. Our Prodigy has been used by us for over 5000 miles in last 10 months...usually we don't even know it is working because the additional braking provided by trailer is so smooth due in part to smooth operation of Prodigy. In fact that is biggest problem...forgetting to get handheld in-unit device out of trailer and plugging in to cigarette lighter socket prior to taking off with trailer in tow. Not having to "splice in to under dash wiring" was a big plus for me thus this wireless device sounded perfect and it has been. Synchronizing to our tow vehicle was accomplished by our trailer dealer...they could not get it to work with our TV and used one of their TV's, just as Prodigy instructions advise. 311240

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

This is by far the best product I have bought for my trailer! Super easy to install and set-up! Just pre-drill 4 holes where you want to mount the system and using the enclosed self-tapping screws, screw it into your trailer frame. That is the hardest part!! Plug it in, turn on your car and then turn down the setting on the hand held remote then plug it into any 12-v lighter, step on the brake and wait for it to read 0.0 and you're done!! A little adjustments along the way but for the most part its done. Bought this because I did not want to drill into my tow vehicle. Buy this product because you will not go wrong!! Also Etrailer.com shipped it super fast! Love the controller and love the website!! 41614

I would have to say that the product is fantastic. I still say that it is excellent, but the instructions are a little lacking. (After talking directly with Takonsha) I was having a lot of trouble pairing the device. Why it is not paired from the factory I don't know. The best vehicle to perform the initial pairing with is a Dodge/Ram truck or a GM vehicle after 2012. These just get it done. Once that was completed I never had another issue. Also a note for those attempting to pair with a Mercedes-Benz product. It can be done with the Mercedes-Benz if the pin at the 5 O'clock position is covered with tape in order to complete the pairing. This also was information relayed to me by Takonsha. 251293

Saw a thread about this product on the Jeep Forums and browsed over to etrailer.com to check out the product. Installation of the product is straight forward. I have a trailex 8045. The most time consuming part of the install was moving and adding some wire extensions so that I could put the control box on the inside rail to prevent damage from road debris, etc... The instructions that came with the controller were helpful in installing the brake controller on the trailer however the video on etrailer was much more helpful in setting up the handheld unit. Very happy with the unit. 166422

An excellent choice for a trailer that uses multiple tow vehicles. Easy to install. The directions need to be followed closely and the power on your plug has to be set up correctly with a 40 amp breaker available on the site. I have used the controller for loads of various sizes all the way up to max limit and the controller's tuning wheel allows quick refinement so the trailer slows nicely with the tow vehicle. Very easy to tune with just a short, slow speed application of brakes and the controller in your hand. This will be the controller I put on any other trailer in the future. 265283

I have a 2014 Mercedes Benz GL350 and could not get my MB dealer to install a brake controller. I order the Prodigy RF model from etrailer and received it in 2 days. I followed the simple mounting instructions and tried pairing the unit with my vehicle first but it did not work. I then paired the unit with a GMC pickup successfully and then connected the cable back to my vehicle and it worked immediately with my vehicle. The unit and the brakes work fine now on my 20' SnoPro snowmobile trailer. Awesome product and awesome service and communication from etrailer. 170619

I installed this controller on our flat bed about 2 years ago. We sometimes pull with our Porsche Cayenne, and I did not want to drill into dash area to mount a controller and loose knee space. For some reason due to the peculiarities of the German wiring, I could not get controller to pair. Tekonsha tech help and online searches led me to get it working. I really like being able to switch between 3 tow vehicles and have the brakes work. We just bought a tandem cargo trailer with brakes, so without a question, ordered the same setup for the new trailer. 389685

This product work perfectly and was very easily to install. We used it pulling a tent trailer with a 2015 Volvo S80 . It allowed us to avoid tying into the brake system of the car which would have voided the warranty. All that was required was a connection to the car battery, not the car's braking system. It provided very smooth braking though out many miles of driving through the mountain of the western USA! 248071

Perfect for multiple tow rigs Works as well as the Prodigy we all know and love, except wireless. People who are concerned about interferance with the wireless aspect of this unit put your mind at ease. Even if this happens (which is about as likely as me winning the lotto) the controller will still function on its last setting. This is a great choice if you have more than one tow rig. 3167

The key now is to start the vehicle, plug in the hand held controller and then plug in the trailer, works really well. 248366

From the measurements that you have given me, I recommend getting about 35 to 40 feet of 10 Gauge Primary Wire, # 10-1-1, in order to wire the electric brakes on your trailer. Depending on the tilt function of your trailer, you may want to order a bit more to be on the safe side. I have attached a wiring diagram that illustrates the basics of wiring your trailer. A couple additional items that may want to...

  • Brake Controller Recommendation for a 2012 Mercedes GL450
  • In order to install a trailer brake controller on your 2012 Mercedes GL450 it will require hardwiring in the controller unless the Mercedes dealer has a wiring harness specific for a brake controller and your vehicle. If they do then you will need to wire in the controller to the Mercedes harness by function. On a brake controller, the wire functions are as follows: White is ground Black is 12 volt power Blue is output to the trailer brakes Red is input from the brake switch On...

  • Location of Brake Controller Wiring Connector on 2014 Fleetwood Bounder on Ford F-53 Chassis
  • On the 2014 Ford F-53 chassis the brake controller port is located on the left hand side of one of the steering column supports. The plug is gray in color, and you should be able to see it if you look to the right of the emergency brake release handle. If you don't already have a brake controller, I can highly recommend the Tekonsha Prodigy P2, part # 90885. To install the controller onto your motorhome, you would use harness # 3034-P which is compatible with Tekonsha brake controllers.

  • Installing a Brake Controller on a 2015 Mercedes-Benz GL-Class
  • I have a solution for you, but unfortunately there are no plug-n-play style wiring adapters available for your 2015 Mercedes-Benz GL-Class, and it is usually fairly difficult to hardwire in a brake controller because you have to locate the stop light switch. What I recommend using is the Tekonsha Prodigy RF Wireless Trailer Brake Controller # 90250. This is the best option for your Mercedes-Benz because it plugs right into the 7-Way wiring harness on your Mercedes-Benz. The RF will activate...

  • Will Tekonsha Prodigy RF Wireless Trailer Brake Controller # 90250 Work on 2007 Mercedes GL-Class
  • Trailer brake controllers, including the Tekonsha Prodigy RF Wireless Trailer Brake Controller # 90250, are not vehicle-specific. You can use any trailer brake controller in just about any vehicle. The Prodigy RF is a great option if you will need to often transfer the controller between different vehicles. If not, one of the standard Tekonsha units, such as the P2 # 90885 may be a better choice. Certain vehicles that have a bulb-out sensor (Mercedes-Benz, BMW, Audi and Porsche) will...

  • Brake Controller Installation Information on a 2015 Audi Q7 and BMW X5
  • To install a brake controller in either a 2015 Audi Q7 or BMW X5 there isn't a custom install harness for either. I spoke to my contact at Tekonsha and he said that for the Audi you will need to check out the FAQ article I attached to the right for what is required to install a brake controller in the vehicle. The BMW X5 would be a difficult vehicle to install your brake controller into. At this time there is no fit information for installing brake controllers in this vehicle and...

  • Theft Deterrent Recommendation for Prodigy RF Brake Controller # 90250
  • The Prodigy RF brake controller # 90250 uses regular hex head bolts to secure it to a trailer though you could use different bolts if you wanted to. A hardware store would have a nice selection of bolts that require uncommon tools to install or remove. The Prodigy RF # 90250 won't work without its handheld unit. And if someone wanted to try to buy a new handheld unit the cost is not as low as they might think, # 90251. They would have to know that though before attempting to steal it...
