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 P3 controller sits level on a horizontal plane and is pointed in the direction of travel, 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.

Power Boost for Heavy-Duty Towing

Aside from smoother, more efficient braking, Tekonsha's P3 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.

Storable Settings

Customize your P3 and store settings so that you can easily access them later. If you tow multiple trailers, or the same one but with differing loads, store the desired boost and power levels for each so that you don't have to completely reset the controller every time you switch between the trailers. Do other drivers use your towing setup? Customize the P3 display with your desired screen color, brightness and language, and you can easily return it to your preferred settings the next time you tow.

Customizable LCD Display and Advanced Diagnostics

The P3's LCD display features a distinctive look with multiple color and contrast options. It also includes a highly advanced, easy-to-understand roadside diagnostics display. The P3 advanced diagnostics not only notify you of potential problems, but they can also tell you where to begin troubleshooting.

Safety Features

The Prodigy P3 offers advanced safety features to prevent damage to various components of your towing setup. Integrated reverse battery protection shields the brake controller and your trailer's breakaway system from shorts. When the P3 is not in use, it will be in power-saving mode. In this setting, the power draw falls to only 3.6 milliamps, 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 P3'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 lever is easily accessible. Pushing this lever 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.

Automatic Leveling and Simple Installation

The self-leveling feature of the P3 ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount it in your cab at any vertical angle, and the controller will level itself automatically thanks to its 360-degree rotational range.

Correct P3 mounting360-Degree P3 mounting

Note: The P3 must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.

P3 mounted in bracket P3 mount

Installation is a snap. After mounting the P3 unit in your cab using the included bracket, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller. To transfer the P3 to another vehicle or to remove it for storage, just unplug the unit and slide it out of the bracket.

Installation Accessories

For even easier installation, a vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

Note: If a custom brake-control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

See also'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.

Average Customer Rating:  4.9 out of 5 stars   (5098 Customer Reviews)

Proportional brake controller automatically levels when mounted within a 360-degree vertical range. Includes customizable LCD display, storable settings, 3 boost levels, battery protection and continuous diagnostics. Transferable between automobiles.


This Tekonsha Prodigy P3 was recommended to be by a friend who works at an RV dealership service center. This is my fifth trailer brake controller over a forty-year period, and my first progressive controller. I really love this controller. My truck has a factory towing package, but was manufactured prior to inclusion of integrated controllers. Since the truck has factory towing, the installation was very simple. The installation instructions were clear and complete. I would definitely recommend this controller to anyone looking for a dependable, easy to install and easy to use controller.

After a year of use, I am very happy with my beak controller. I would purchase this controller again, without any hesitation. I highly recommend it.

I mounted my Tekonsha P3 on the dash just to the left of the steering wheel. Has very easy access to quickly activate the lever on the bottom of the unit to apply maximum trailer brakes. But I needed a wiring harness almost double the length of the Tekonsha Wiring Adapter so I just purchased two and spliced them together to make one long one......yea I could have saved money and just sliced in longer wires....Am very happy with the Tekonsha P3, With this mount it makes it easy to disconnect and put into my Ford F150 or my Tacoma.

Still lovin it! Works Great!

I have a 2018 BMW X2 that did not come with a factory tow package. I had an etrailer hitch and 4 way plug installed last year and has been perfect since. I just recently purchased a camper and needed to have a Brake controller & Brake controller 7 way deluxe kit installed. My mechanic installed them with the detailed instructions that the units came with without any issues. The Tekonsha P3 is extremely user friendly and is working flawlessly. A bit overkill for my car being I can only tow max 3500 pounds, and my camper is 1 axel. this unit is rated up to 3 axles. I look at it like this way, when I trade in my BMW I will take my P3 with me. etrailer is amazing with the support & products they provide and I highly recommend them to anyone who asks me.

Love the P3, so easy to use and will be using this on my next vehicle when I trade this in. Highly recommend this unit.

I have not used this yet, but I was able to install in my ‘22 Honda Ridgeline in a pocket in the dash as shown in a video on eTrailer. I used a piece of 1” masking tape, marked with lines 5/8” apart to stick where I wanted to cut the hole for the plug & wires. I could not get the wires to come back down to the left of the pocket, so I taped a couple of feet of string trimmer line to the plug, worked the line up and left. I had to pull the trim panel from under the steering wheel to get my hands where I could feel it and pull it down. (Use a trim tool and remove the left side trim before pulling the panel under the steering wheel loose.) Be careful of the little electric sensor and air tube that are plugged into the right side of the panel. After guiding the the plug with the line, it was not much work to route it over to the left side where Honda put the brake plug. It was a booger plugging it in, because the plug on the truck was taped with little room to maneuver. The instructions with the controller were clear about which screws to use. Just remember you are screwing them into plastic, so don’t turn them too hard. The controller came alive as soon as I plugged it in, and it looks almost like a factory install in this spot.


Great aftermarket trailer brake control ler.


Used this in my Hyundai Santa Cruz. Fits great works great plus matches the interior colors.


I bought the P3 to replace my factory integrated brake controller. Factory controller cannot deal with hydraulic disc brakes on new fifth wheel. Installation was fairly easy on my 2010 Ram 3500. However the Dodge dealer could not get rid of the service message that appears on truck display after factory integrated brake controller was unplugged. I gave dealer the printed instructions from etrailer on how to do it, but dealer says instructions incorrect.

The Dodge Dealership will be needed in order to get rid of the error, since they will be needing to disconnect the ITBM for you. In order to disconnect the ITBM and not get the warning lamp, your local Dodge dealer will have to reconfigure the TIPM Totally Integrated Power Module, of the truck. Once that is reconfigured, then the ITBM can be unplugged.

I recieved my brake controller quickly. It arrived in a padded envelope with a small hole in it. Opening the envelope, the retail box that holds the brake controller was open and parts spilling out into the padded envelope. I am concerned that it may be damaged, but I do not have my trailer yet. Who ships a flimsy box with a $xxx electronic item in a padded envelope? Why not a box?? Shipping is an area for reviewing!!

Customer Service will reach out to you.

Prodigy 3 is our go to brake controller. We've been using it successfully for many years towing our 19' Escape and our 30' Airstream Classic. Works really well in our Sprinter 2500 and our GLS 580 tow vehicles.


Very impressed with my order. Etrailer tracking nad delvery is the best I have ever seen. I follwed my order from the time I placed it until final delivery on their web site, awesome.. I haven't installed the brake controller as of yet, but will give feedback after installation.

Has worked flawlessly. Easy install.
Jim S - 04/10/2022


Works perfectly for me. I switch between P1 and off, depending on whether I'm driving in the city on on the highway (P1 is too sensitive for city driving, the brakes lock up and make the trailer bounce around). It took me a little bit to figure out the settings I liked ,but now it's working great.

One thing to note is that the directions to find the right setting involve getting up to speed and then hitting the trailer brakes to stop the vehicle + trailer. No matter how much I messed with settings, I couldn't get the brakes calibrated this way (the brakes didn't lock up in the way described). So instead, I just found a good setting via trial and error during driving.

This is still working great after a year. The calibration procedure getting up to speed and using the trailer brake in a parking lot never worked for me, but after some usage, Ive figured out the right levels for my truck and trailer. Last fall I got my brakes inspected on my truck and the mechanic confirmed they had the appropriate wear and tear for my mileage, so the evidence suggests the trailer brake is doing its job!

Perfect! Plug and play on 2017 4Runner. Easy setup and adjustment. Swift delivery and follow up customer service. Used zip ties to mount for a smoother profile. Less bumping into it with knees and knocking it loose from standard hard bracket.


This brake controller was installed in a motorhome on a E450 Ford chassis that came with the Ford brake controller harness installed from the factory. Although factory wired for a Ford brake controller the Ford brake controller would not work because the motorhome did not come with the digital instrument panel and steering wheel with the required controls.

The Tekonsha brake controller with the Ford adapter harness was very simple to install, plug and play. The Tekonsha brake controller also detected a brake fault that the Ford controller in my F150 did not show. The Tekonsha brake controller works perfectly stopping my 7000 lbs. enclosed car hauler trailer.


Super simple to install. I spent most of my time determining where I wanted to mount the thing. In the end, I used the detachable mount, for two reasons.

1. To reduce the number of things that I can bump against, when they are not absolutely needed. In this case, if I'm not towing, I don't need the controller.

2. As much as possible, I try not to have anything in the truck that is drawing current if it is not in use. And unplugging the cable from the back of the P3 is an absolute pain, if the P3 is up against a surface; I could not get to the "release clip" if the controller was in place.

The one thing not noted in the instructions is that you need to open the fuse box inside the engine compartment, and install a 40A fuse. Fortunately, there are several videos which make this clear.


Excellent product! Great service! The installation instructions were detailed and easy to follow. The install kit had everything I needed to install my brake controller. I especially found the videos I found on your site helpful as well.


The Prodigy P3 came on just as the instructions said it would. Although I have not used it yet it looks good in my ‘15 LX. I look forward to great service towing my 20’ flat trailer with tractor, rotary cutter and box blade. My to the staff at etrailer.


I have a 2002 Land Rover Discovery and it turns out Land Rover doesn't make the parts to enable towing a trailer with brakes. I ordered the Tekonsha Prodigy P3 brake controller and was able to get it installed with the ETBC7 Universal Installation Kit. I had it installed by a Land Rover maintenance shop but the fact that it worked as advertised was great. I'm glad this was an option for me considering my "non-standard" but capable towing vehicle.

This unit was easy to use, experimented in a vacant parking lot to get the setting right for my towing of a Casita camper. I did not want to drill into my dash panel to mount it so I cut a piece of 1/2 inch plywood /painted to insert in open slot in dash below radio. I cut a wing than is for mounting the bracket to. This allows the controller to be away from my knee and within easy reach. I cut the board from a template of cardboard to see hold tight a fit I needed so I would not need screws or double sided tape. I wanted to remove it when not towing. I tapered the board so when inserted it wedged tight at the final position. It does not move when driving even on rough uneven surfaces. My tv is a 2012 Nissan Pathfinder.


This is a great plug and play controller. Using it on a 2020 Chev Silverado 1500 towing a 22-foot Jayco Travel Trailer. It woke great. Its sensitivity adjustments are extra good. It is 10 times better than the unit I was using initially which was erratic and very jerky at slow speeds. This unit is very smooth at any speed. Great purchase.


The Tekonsha Prodigy P3 Trailer Brake Controller has worked great for a year and I expect many more years of satisfaction. It actually replaced another one I had for over 6 years, but the other was shorted out when some repair work was done on my pickup. I pull a 2021 Jayco Eagle HT 28.5, which has a loaded weight of around 10,000 lbs. etrailer had the best price on this the first time I bought it and this second time. Great company! Very helpful.


First, a huge "Thank You" to Janice!!! You are the best, and the main reason I am the proud owner of Tekonsha P3 Brake Controller! (see, I initially had an issue with my standard online payment service and almost canceled my order because of it) So I went old school and picked up the phone, one with a cord and spoke to a human being. Her name is Janice, and she made me feel confident that I could trust her and etrailer. And as a result, 4 days after placing my order with her I received my package. That's incredible. I am very happy and will most certainly do business with etrailer again in the future because of Janice.

I don't have any experience with brake controllers. So I can't really comment on how much better or worse this one is to any others. But since I am new to the B/C scene maybe this can be considered an unbiased, non professional review of the Tekonsha P3.
My general skill level is "requires supervision around all power tools". But I do have some mechanical ability (snicker). So I will just say, if I could install this thing anyone should be able to do it. Of course I also bought the OEM wiring harness for my vehicle so even I was able to figure out which plug went where. On A scale of 1 to 10 I give it a 3 (I'm somewhat large and getting under the dash wasn't easy or it would be a 1). And as others have said, deciding where to mount it actually took longer.

I attached mine to the top of the lower dash cowl and it fits almost tight to the dash but still within the 180 degree limit. This positions the controller at the same height as my knee and puts it within fingertip reach while resting my hand on my knee. I can see the controller perfectly through the steering wheel spokes. I went with the green screen background. it seemed to provide the best view in all lighting conditions.

The controller itself works perfectly and the set-up was a breeze. Once installed all the functions worked as described. The real time vehicle diagnostics are a plus. I like being able to monitor my battery voltage to the decimal place if I want to. I'm sort of a techno geek so this is really cool. I set the B/C voltage per the instructions and will only use the boost feature if I am in a hurry or feel the trailer is at max load, but my truck is 8k lbs so you may want to set yours to suit your own conditions.

I highly recommend the Tekonsha P3 brake Controller if you want the latest and probably the best controller out there in this price range. I highly recommend the OEM wiring harness if your skills are not pit crew comprable and want the easiest install possible. And, I highly recommend you buy it from etrailer if you want to get it at the best price available (I checked them all) and want the added security you're buying from one of the best online retailers that sells this product. And do yourself a favor, go old school for a change, use the phone and call them, and ask for Janice, although I'm willing to bet everyone there is as nice as her.

How long is the wiring harness? I want to mount the brake controller on the right side of my steering wheel. It looks short in the picture. Thanks! Tom

Installed this on my GMC 3500 Duramax with factory integrated brake controller. Not happy with the integrated brake controller on my truck, had problems from the start on 3 different occasions with "Service Trailer Brake" warning on DIC, which of course means NO TRAILER BRAKES. Decided the P3 was the perfect solution. Many more features than the IBC, plus the P3 will also work with electric over hydraulic disc brakes should we ever need that in the future. Fairly easy install on this particular truck, the most difficult thing was running the brake wire from the controller to the 7-pin plug. (This is only required when installing in a vehicle with a factory installed brake control) Well worth the extra effort.

Recommendation...dont mount it to low out of reach. When you have a trailer go astray...your seat belt will tighten and then you cant reach your controller to help you out. Believe me I mounted my too low and out of reach, and I was seconds from ditching the truck and trailer. Was very lucky. Just a recommendation.

Installed P3 this weekend in 2013 Tundra Crewmax with towing package and pre-wire. Extremely easy, even with the center console installation. Will let the photos tell the story. Did have to combine the P3 included harness with the additional OEM harness to gain the length I needed. Plug and play with the pre-wire. Hooked up to trailer and set boost levels for varying loads. Works great! Vast improvement over older model Tekonsha controller in my Ram 2500 Diesel. Pull a Kiefer BP horse trailer: about 3600 lbs empty, 7500 with 3 quarter horses and gear. Usually pull 6-8 times per year, with only 1-2 horses. Short distance and flat terrain. It took about an hour to install. Dad is a retired USAF/FAA radar technician with every tool known to man. He QC'd the job. Will try to write better review later.

how hard is it to remove small center console plugin great installation thanks Mark
-- comment by: mark d - 11/14/2013
To remove the small center console cubby hole you need to open both 12V outlets, then using your thumb and index finger, slowly work the cubby out. I used a very thin straight edge screwdriver to get it started as well. Helps to have two people. Once out, I used a rotozip tool to cut the back out. I thought I could get away with simply drilling a hole for the wires, but you will need more room. Recommend leaving a lip on the bottom edge where you cut out so small items dont fall behind your dash. Hope this helps.

Great write up Chris M. I just mounted mine and would like to make one note about the little yellow clips that hold in the console. They are very good at making a quick exit to some unknown location but I was able to fine the Toyota part number incase someone may need it. It is 90467-10203. They cost about a dollar. I got lucky and finally found the one I lost and saved myself a dollar.

  • Setting an Electric Trailer Brake Controller for Optimum Braking with a 2012 Dodge Ram 2500
    There is an easy way to set up a brake controller for the right amount of braking for any load. If the controller has a boost feature like the P3 you referenced, # 90195, then before setting boost follow these steps: Connect trailer to tow vehicle. With the engine running set the power (with Power Buttons) to indicate 6.0. Drive the truck and trailer on a dry level paved surface (like an empty parking lot) at 25 mph and fully apply Manual Override Knob. If the brakes lock up adjust the...

I would check the front and the back of the connector for corrosion or exposed wires and fix as necessary.

    The Tekonsha P3 would need to be mounted so that it is level in the side-to-side orientation, and pointed so that it is parallel to the direction of travel. The controller does not have any error codes specific to the controller being out of horizontal, but installing it so that it is not level or parallel to the direction of travel would cause erratic or poor brake performance, therefore you should make every effort to install the controller as stated in the instructions.

    Since you have a brand new tow vehicle and a new Tekonsha P3 brake controller I would first focus your troubleshooting efforts on the wiring in the trailer. Something is causing an excessive current draw from the controller. The most common causes for an overload message on a brake controller are a corroded trailer connector, damaged trailer wiring or an issue with the trailer brake's wiring or magnets. First verify that the P3 is correctly set to the type of brakes installed on your...

  • Is 12 Volt Accessory Circuit Required on 7-Way to Install Brake Controller
    If you have only the need for a brake controller output circuit on the 7-way you do not need to activate the 12 volt power accessory circuit. Those two circuits are independent of each other.

  • How Does Prodigy P3 Brake Controller Install to 2011 Chevy Silverado
    No plug is present under the dash of your 2011 Chevy Silverado, but the needed wires are already run. You will connect the Prodigy P3 part # 90195 brake controller wiring with the vehicle wiring already present under the dash. I attached an install video for the P3 on a 2011 Silverado just like yours for you to check out as well.

  • Use of a P3 Brake Controller on 2005 Ford F-350 Instead of Factory Controller
    I can help you understand the compatibility of the P3 and your 2005 Ford. Because your Ford already has a factory installed brake controller, the truck's computer has been set to identify that brake controller only. When you remove the plug from that controller and plug it into the P3 # 90195 there will be an error code because the Ford's computer does not recognize this as being the OEM controller. When you take it to the dealer they are essentially deactivating factory brake controller...

  • Tow Package Wiring Location for Brake Controller Install - 2016 GMC Canyon
    According to my research, the 2016 Colorado/Canyon with the factory 7-way won't have a plug under the dash for installing a brake controller, but there will be bare tow package wires that you can wire the brake controller directly to. The tow package wiring is located behind the left kick panel, as you suspected. The wiring pigtail that came with your brake controller would wire up to the tow package wiring as follows: Black pigtail wire connects to red/green tow package wire (12-volt...

  • Troubleshooting Trailer Brakes That Apply When Trailer Is Placed In Reverse
    I'd be curious to know which fuse is blowing and if this is a suddenly occurring problem or if it has been happening since the first time you used the trailer with that truck. If the trailer brakes are being applied when the vehicle is placed in reverse, two possibilities immediately come to mind: 1) Either the connector on the trailer or on the vehicle is mis-wired. Since the Tundra has the factory tow package, I'd suspect that the mis-wire is on the Airstream, unless the connector on...

  • Prodigy P3 Brake Controller Light Stays On
    Brake controllers such as the P3 you referenced # 90195 will go into a sleep mode after about 15 minutes of it sensing no movement. If you peek through the window after 15 minutes then it should be in sleep mode. Opening the door or causing movement to the truck could cause it to wake back up.

  • Probable Tow Package Wire Colors and Functions on a 2007 Chevy Silverado, New Body Style
    Wiring color and corresponding function varies among vehicle manufacturers and most of the time, they do not match up with the color/function on brake controllers like the Tekonsha P3, # 90195. For a 2007 Chevy Silverado, the Red/Black wire will attach to the brake controller black wire. The light blue/white wire will attach to the brake controller red wire. The white wire will attach to the brake controller white wire. The dark blue wire will attach to the brake controller blue wire. The...

  • Tekonsha P3 Display Back Light Works But No Display
    I have spoken with one of my friends at Tekonsha, who tells me that he has heard of this problem from time to time. Your controller needs to be reset. To do this, simply unplug the wiring harness from the rear of the unit (while the trailer is NOT connected) and wait 10 or more seconds. Then plug the unit back in. This should return the unit to normal operation. I will link you to the instructions for the P3, in the event that you no longer have them.

  • Is there a Brake Controller Wiring Harness for Elecrical Connection on a 2006 Buick Ranier
    Yes, your 2006 Buick Rainier will have a bundle of wires under the dash to the left of the steering column that will need to be spliced to the wiring included with the Tekonsha P-3 Trailer Brake Controller, item # 90195. This installation is the same as the one you saw in the video for the 2004 Trailblazer, and will work for the 2004 - 2006 Rainier with factory tow package. There is not a connector on your vehicle, so the wires must be spliced and the P-3 includes butt connectors for this...

  • Location of Factory Wiring Harness to Install a Trailer Brake Controller on a 2008 Chevy Silverado
    GM has stopped supplying a port for a brake controller several years ago, so you will need to splice the wires from the brake controller. The good news is that the wires are already run and are present under the dash, above the brake pedal. The wires will be bundled together, possible tied to another harness. If you pull them out, you should also notice a tag that indicates the function of each wire. On the brake controller, the white wire is ground, the black wire is 12 volt power, the...

  • Will the P3 Brake Controller Use the Same Connector that the Prodigy Brake Controller Uses
    Yes, the 4 flat connector that plugs into the back of your Prodigy brake controller will plug right into the back of the P3, item # 90195, brake controller and work properly. If the original brake controller is not operating properly I recommend testing the wiring with a circuit tester, item # 3808, before installing the new brake controller to make sure the connector is wired properly. I will list the wire functions below for you. White = Ground Black = 12 Volt Power Red = Brake Light...

  • Tekonsha P3 Trailer Brake Controller Will Not Go Into Power Saving Mode, 2005 Chevy Silverado
    The Tekonsha P3 Brake Controller, # 90195, only draws a few milliamps even when it is on. This power draw is so minimal that it will not drain the battery on your truck. If the screen on the P3 is blank when the truck is parked, that means it has gone into power saving mode. Otherwise, to remove power completely, it will need to be unplugged. I spoke with my contact at Tekonsha and he stated that usually when the P3 does not go into power saving mode it is because it is receiving a signal,...

  • Will the Tekonsha P3, part # 90195 Drain my 2009 Dodge Ram Battery While the Vehicle is Off
    The Tekonsha P-3, part # 90195, will go into a sleep mode after several minutes of no activity. The power draw while in this sleep mode is so small that it is really not worth worrying about, certainly not enough to discharge your battery. If it would make you feel better, you could unplug the harness from the rear of the unit if the vehicle will be left for long periods of time. I attached installation instructions as well as a video of this product being installed onto a similar vehicle...

  • Leveling Tekonsha P3
    The Tekonsha P3 # 90195 can be mounted anywhere between -90 degrees (straight down) and 90 degrees (straight up), so having it tipped for easier viewing should not present any problem. Just make sure the unit is parallel to the direction of travel as shown in the instructions, and you will be fine.

  • Should 12 Volt Hot Lead on 7-Way Trailer Connector Be Hot All the Time, WIll it Drain the Battery
    The light that indicates that the 12 volt circuit is hot is normal and it will not drain the battery. Think of it as the battery having a really long positive terminal that just extends to the rear of the vehicle. If nothing is drawing power from it, it will not drain the battery. If you did have a trailer connected, for example, and that trailer used the 12 volt circuit for an accessory that remained on all the time, that would draw power from the vehicle power and could potentially drain...

  • Brake Lights on a 2005 Dodge Ram 2500 Stay on with Brake Controller Connected
    On your 2005 Dodge Ram 2500, the fuses that protect your tow package circuits are located in the fuse box located under the hood. The fuse box should have a legend on the inside of the cover that outlines which fuse protects which circuit. If your fuses are blown, I would recommend to check all of the wiring and the connections for your brake controller and the 7-Way connector to make sure that none of the wiring is shorting out and causing the fuses to be blown. I would also recommend...

  • How to Install Prodigy P3 Brake Controller to a 2009 Acura MDX with a Factory Tow Package
    To connect the Tekonsha Prodigy P3 Brake Controller, part # 90195, to your 2009 Acura MDX you will need to hardwire the included pigtail wiring harness directly to the factory four wire harness that plugs into your factory brake controller port. The wires will connect color to color, red to red, blue to blue, black to black, and white to white. The Honda wiring harness will not work. I do not have a brake controller wiring harness available for a 2009 Acura MDX that will plug into a factory...

    I would recommend the Tekonsha P3 Brake Controller, item # 90195, for your application. This brake controller has several functions that will help when pulling a dump trailer. You will be able to set up the controller for towing the trailer unloaded, and then when additional loads are applied you will be able to use the boost settings to start the braking at a higher setting so the controller will instantly apply additional power and brake smoothly. There are 3 boost settings to choose...

    If the gain on your Tekonsha P-3 Trailer Brake Controller, part # 90195, is turned up, you should get up to 12 volts of power. What you will want to do is disconnect or unplug your brake controller for a minute or two, then plug it back in, which will reset the controller. Then, you will want to adjust the settings again.
