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.

In all honesty, I have to say that I am very pleased with the product. It was exactly what was described and did exactly what it needed to. Delivery was in a timely manor and was shipped in packaging suitable for the contents. If I was to mention any con was that I wished it had come with more instructions on the installation. Thank goodness for the web; I was able to look up my vehicle and find the information that I needed to install this product. 218793

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

It was easy to install. Just plug in under the dash with the prewired wiring harness. I first installed the permanent mounting bracket. I was unfamiliar with its use and hard to see it when it is mounted down below the steering wheel. Installed the removable mount, it allow you to bring the unit up to where you can see it. The boost is help full for pulling at rated load behind a 1500 Chevy Silverado. I was moving a tractor on a trailer and the road out was a downhill gravel road. The plug is powered at all times. I would have thought it would shut off when the ignition was off. If your truck sits a lot and just used for the weekends, you may drain the battery. Not sure of the load, it may not matter, except the display does stay lit up. 48918

I ordered a Tekonsha 90195 P3 Brake Controler and the GM 3015-P Plug- in wiring adapter. I'm replacing an older Tekonsha Voyager unit on my 2004 Chevy 1500 pickup. New items installed easily in less less than an hour, as described on your web site.Have not road tested the unit yet but expect this controler will prove to be a good one. I placed my order on-line on Monday (also a Holiday) and recieved the items two days later on Wednesday. Recieved several e-mails from Etrailer keeping me updated on the order. Great service. Have already recommended Etrailer to others. 82687

Every thing is work very well. The brake control I bought has turned out to be a big improvement over the older controller I was using with my 30 travel trailer.

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

  • How To Install a Brake Controller in a 2011 Chevrolet Silverado
  • In 2007, Chevrolet stopped offering plug-in connectors for brake controllers on their full size trucks with tow packages. Instead, you will have four or five blunt-cut wires bundled underneath your dash. The wire colors should be red with a black tracer, white, light blue with a white tracer, dark blue. You may also have an orange wire for a center high mount stop lamp function, but this would not be used for a brake controller installation. I would recommend the Prodigy P2 brake controller,...

  • On a 2005 Chevy Silverado 1500, If you are facing the front of the truck looking at the power distribution box, there will be a post at the back left side and a fuse slot near it. It is that fuse slot that you will install a 30 amp fuse. I have included a picture that should help. I have also linked an article that will also help.

  • The reason you would not want to install a 30 amp fuse or circuit breaker in a 4 brake magnet application, when installing a Prodigy P2 brake controller, # 90885, is that the extra amperage required to break the circuit could cause an issue with the wiring on the trailer or vehicle because it would take longer for the circuit to spike to 30 amps.
