Installation of Tekonsha Brake Controller Adapter

Junction BoxBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.


This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

2010 GMC Sierra

I have purchased products for various vehicles from etrailer in the past. I have always been very satisfied with the Products, Service, and Shipping. This time was no different. It was a direct plug and play for my 2004 GMC Sierra 2500HD 4x4 and the Tekonsha Prodigy P3 Trailer Brake Controller -Item # 90195, that I had purchased previously. I had purchased the Prodigy P3 and the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires, Item # ETBC7, for my 1985 Ford F-150. Now I can use my Brake Controller for both of my trucks, in whichever one that I am using at the time. I have also used the website for information, viideos, and wiring diagrams to do troubleshooting in the past, and will continue to do so in the future. Thank etrailer, you are the best. Keep up the good work. 443442

I've used a time delayed controllers for 15 years to brake my popup camper, where I became accoustomed to the initial "tug" from the trailer whenever I depressed my brake pedal. The Tekonsha P2 was my entry into proportional controllers when I traded up for a 25' Airstream. The installation was simple on my GM which allowed me to essentially plug and play. The P2 display seems a little "dated", with it's LCD type fonts, but once you get used to the code, it's really not a problem. I didn't know where I might be installing the controller, so having a unit that allowed 360 degreed of rotation gave me the options to install it almost anywhere on the dash, including my near vertical lower dash. That was a big plus. The biggest change for me was in the ride. On my maiden trip (around the block), I was sure that the unit was defective. Although the manual braking lever resulted in a definate stopping of the trailer, when I depressed my car brakes, there was no "tug", no lurching, no lock-up no apparent anything...BUT that was just the point. This controller applied just the right amount of braking on the trailer that was necessary. It was near impossible to tell that that you were stopping an additional 5000 lbs. I especially like it's "boost" option which applies additional inital braking power to trailer if you choose. Although my experience is a total of 2 miles with this product (soon to be 4000 mi), I'm quite impressed with it's abilty to do it's job. If I don't update my review in 2 months, it's becasue I have no complaints with it. 89541

The Tekonsha brake controller that we purchased about a year ago has been performing flawlessly. We are very pleased with the performance of the unit.

  • Brake Controller Installation in 2006 GMC Sierra Pickup
  • When installing a trailer brake controller in a 2006 GMC Sierra that has a factory 7-way you will both plug in the controller at the under-dash port using the brand-specific wiring adapter AND make some connections under the hood at the power distribution box. For instance, to install the Prodigy P3 # 90195 you would use wiring adapter # 3015-P. I linked an article that covers this process in detail along with photos to help you. One of the two wiring connections to be made provides...

  • Is Weight Distribution Needed for a 2018 Forest River Cherokee Wolf Pup 16BHS
  • The general rule of thumb is that if the gross vehicle weight rating (GVWR) of the trailer is more than 50% of the GVWR of the vehicle, a weight distribution system is recommended. Since the 3877 GVWR of your trailer will in fact be more than 50% of the GVWR for both your 2017 Chevrolet Silverado and 2005 GMC Yukon, I would recommend you use a weight distribution system. In order to choose the correct weight distribution system, you will need to find the total tongue weight (TTW) of...

  • Recommended Trailer Brake Controller and Harness for 2006 Cadillac Escalade
  • For your 2006 Cadillac Escalade, I highly recommend the Tekonsha Prodigy P3 Trailer Brake Controller # 90195. This is an excellent, proportional controller that will activate the trailer's brakes at the same time and with the same intensity that you apply to them in your Escalade. It features an easy to read LCD display, storable settings, and continuous diagnostics that will alert you to any potential issues. This unit is well known for its reliability and ease of use.

  • 5th Wheel Hitch for Clean Bed Once Removed on a 2003 Chevy Silverado 1500 Short Bed
  • If you are wanting to keep the bed of your 2003 Chevy Silverado 1500 clean then I highly recommend using the B&W Companion # BWRVK3400-5W because it mounts in the B&W Gooseneck Hitch # BWGNRK1059-5W. Instead of having bed rails in the bed of your truck you just have the gooseneck hitch ball receiver and safety chain loops as you can see in the attached photo. The Companion is made right here in the USA, has a 20,000 lb weight capacity (which is more than your pickup), 17" - 19" of height...

  • How Does Prodigy P2 Install in 2012 Chevy Silverado
  • Your 2012 Chevy Silverado is pre-wired for a brake controller but there is no plug under your dash for the connection of the controller. Instead there are 4 blunt cut wires there that you will need to hardwire to the Prodigy P2 part # 90885. The install video link I attached shows exactly how a brake controller will install in your truck. The truck in the video is a 2013 model but the process would be the exact same.

  • I believe you are looking for an electronic brake controller to tow a trailer with electric-over-hydraulic brakes with your 2005 Chevy Silverado.

If you do not have the factory 7-way there will be some connections under the hood you will need to make, and you will also need the Custom Multi-Tow 7-Way and 4-Way Trailer Connectors # 30955, which will be installed at the spot shown in the accompanying photo.

  • It sounds like you are in need of a brake controller. You would not want full 12 volts getting applied to your trailer brakes at the exact moment you apply your Yukon brakes otherwise your trailer brakes would lock up every time you touched the brakes. The tow package that came with your 2003 GMC Yukon XL gives you most of the wiring for towing a trailer but will not give you everything you would need to appropriately apply the brakes that are on your trailer. For that you will need...

  • Recommended Brake Controller Wiring for 2016 Chevy Express 3500 Van
  • There is not a wiring harness like the # 3015-P for your 2016 Chevy Express 3500. Vehicles with the 7-way and tow package have a blue output wire that is already run for you from the 7-way to the dash near the emergency brake pedal. Some models will have the connection wiring taped and tucked under the drivers side floor mat up towards the firewall. Then you will use # 5506 for the rest of your wiring and the circuit breakers. If you do not have a 7-way, then you will use connector...

  • You won't have to hardwire in a brake controller on your 2017 Chevy Silverado 1500. I double checked and you can use wiring harness # 3016 to plug the P3 # 90195 into your truck. So it will install in the same place as the 2014 Silverado in the video I have linked.

  • Installing Brake Controller On 2004 GMC Sierra With Tow Package
  • Your 2004 Sierra is factory wired for brakes, but you will need a brake controller to actuate them. I would recommend a proportional controller, like the Tekonsha Prodigy P2, part # 90885. A proportional controller uses an accelerometer to determine how quickly the tow vehicle is braking, and will send the appropriate amount of voltage to the trailer brakes so that the trailer brakes at the same rate as the tow vehicle. The result is more predictable and safe braking. In addition...

  • Brake Controller Recommendation and Installation on a 2003 GMC Sierra with or without Factory 7-Way

So if each wheel on your two axle trailer has a brake assembly, or just two of them, this brake controller will work. Brake controllers are not vehicle or trailer specific, so you will be able to use the best one for your application. I recommend going with a proportional controller because they offer the best and safest braking, and will reduce wear on both the trailer and tow vehicle brakes. I...

  • Where Does Brake Controller Plug in on 2019 Ram 1500
  • I spoke to Tekonsha about finding the exact location for the brake controller on your truck and they told me that for your 2019 Dodge Ram 1500 "the connector is behind the area in the attached picture and from what we’ve been told you can reach behind the dash, and around a metal brace to get to this connector." The picture I attached came from Tekonsha. The install harness you need is the part # 3024-P for the Prodigy P2 part # 90885 you mentioned.

There is no quick-connect brake controller port in your model year Avalanche; there was one included up to model year 2006 and this used part # 3015-P.

The dimensions of this are extremely important because it will determine the brake assemblies that fit. The Demco Trailer Brake Mounting Flange # DM60124 has a 2-3/4" pilot hole and has a 4 on 4-13/16" bolt pattern. This is uncommon compared to Brake Mounting Flange # 4-35 which is for 2-3/8" round axles and has 4 bolt holes which are 2-7/8" apart on center, which is what you...

  • How Does Brake Controller Install on a 2007 Chevy Silverado Classic Body
  • Actually to install a brake controller in your 2007 Chevy Silverado you would want to use an install harness like part # 3015-P that plugs into the junction box under your dash. The reason for this is that you have the Classic body style Silverado. The new body style Silverado requires hardwiring but not yours. Check out the install video I attached that shows a similar Tekonsha controller being installed with the # 3015-P harness. I also attached a help article that covers the same thing.
