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.

Video Transcript for Trailer Brake Controller Installation - 2003 Chevrolet Silverado

Today on our 2003 Chevrolet Silverado 1500, we're going to be installing the Tekonsha Prodigy P2 trailer brake controller, part number 90885. In conjunction with the brake controller installation, we'll also be installing the wiring adapter, part number 3015-P. Now, we're going to go ahead and remove this cover right here that gains us access to some electrical ports. To do that, we'll need to remove this little plastic nut, and you can simply pull the cover off and set it aside. Now, you'll notice here on the back side of the cover, there is a wiring diagram. We're looking for the second one over here. It's a trailer 6-way plug.

When you look back up underneath there, we'll go the second one over from the left. That's where we'll be plugging in this end of part number 3015-P. Now, we'll go ahead and take our adapter plug, put into position making sure that it fully snaps into place. Go ahead and put our cover back in place. Next, we're going to go ahead and hold our bracket up into position and then mark two locations that we'll need to drill. To mount our bracket in this location, there's a pocket here.

We're going to be using a screw and a lock nut. It's not supplied with a kit, so you'll need to supply that on your own. Now, we'll go ahead and take our drill, drill from the bottom up at the two marked locations. We'll then go ahead and take our two screws, drop them into place. We'll then take our bracket and slide it up into position. Take our socket and then tighten it down.

Next, we'll go ahead and route our wire over to where our bracket is. Go ahead and use a zip tie or two to help secure it along the way. Just keep it loose for now until we get our wire all the way over. We'll then go ahead and plug our harness into the back of the brake controller. Make sure that the locking tab clicks into place. Now, we're ready to go ahead and take the machine screws and attach our brake controller to the bracket.

Go ahead and tighten up our zip ties, and then go ahead and trim off any excess. Now, we're ready to go up underneath the hood and make our final connections. Now, underneath the hood, we're going to need to remove the cover to the fuse box. Simply pull up. We're also going to need to remove the four bolts here that hold this corner bracing in to allow us to remove the rest of the cover to the fuse box. Go ahead and set the brace aside for now. Next, we're going to need to lift up on these two little tab areas here so we can pull the rest of the cover off of our fuse box. Lift it up like that, set that aside as well. Now that we have our cover off, we have these red wires here. You'll notice that one's a little bit thicker. That goes to this stud right here. The nut that we'll be putting here on the smaller of the two studs is the 6 mm hex flange nut, part number 185916. Then, put the nut down on it. Take our socket and then tighten it down. The other red wire will go over here to this post. It's a little bit larger nut on this one. The nut that we'll be using on the larger stud is an 8 mm hex flange nut, part number 185917. Next, we're going to need to remove just this plug right here in the fuse box. This plug here powers to 12 volt hot back at our 7-way at the rear of the vehicle. That's also with this wire right here goes to on this stud. We're going to be putting a 40 amp fuse in its place. Go ahead and slide that down in making sure the fuse goes all the way down. Next, we'll go ahead and connect our two blue wires here. Line up the tab, make sure it locks into position. Now, sometimes this blue wire is already connected from the factory and other times it isn't. If for some reason you put everything together and your brake controller is not working, check to make sure that this blue wire is connected. Now, we'll go ahead and reinstall our fuse box cover and put the corner bracing back in. Now, you'll see with no trailer connected if you do the manual override, you'll get an NC that will appear on the screen. Now, we'll go ahead and connect our trailer. With our trailer connected, you'll see now that there is a C on the screen. When we do our manual override, gives power to the electric brakes. This knob over here on the left hand side, adjust the maximum output from the brake controller. This button over here on the top right side is the boost feature button or how aggressive the brakes will come on on your trailer. With that, that will conclude our installation of the Tekonsha Prodigy P2 trailer brake controller part number 90885 in conjunction with the GM adapter part number 3015-P on our 2003 Chevrolet Silverado 1500. .

2006 Ram 2500

I have this product on my 2006 Suburban 1500 LT and my wife's 2005 Honda Pilot. I just bought a 2006 Suburban 2500 and the new brake controller will on on this vehicle. I also bought a control cable to make it easier to install the Tekonsha P3 controller. This was a wire pigtail included with the controller/ Since I had trouble routing the cable from the center console to near the brake area, I cut the connector on the controller side of the pigtail leaving the factory connector on. Took the pigtail shipped with the controller and routed the loose wires thru the smaller openings and spliced the two cables together and the jobs done. Worked GREAT!!!!!!!!! The only down side of the installation the GM cable no connecting instructions came with it, But with that said the etrailer Site did have a picture where the GM cable was to plugin at. 727062

In the world of electrical accessories, it's very common to find "some assembly required" and the vendor expects the end user to figure it out. This is not that experience. If you can work a waffle iron, you can use this harness. There is no excuse to run without the electronic controller that you know you need. Paige this up with the Tekonsha P3 for minute control of your braking and much safer towing. Remember the hot rodder's creed - don't make or go if you can't make it stop! 724710

  • How to Wire a 2010 GMC Yukon XL for a Brake Controller
    Yes, you will need to connect two wires under the hood of your 2011 GMC Yukon XL to wire a brake controller to your vehicles brake controller circuitry. To attach those wires to your vehicle you will need a Zinc Plated Hex Flange Nut - M6, part # 185916, and a Zinc Plated Hex Flange Nut, part # 185917. I attached an FAQ article on how this is done below for you to check out, as well as the video that you watched of the brake controller being installed on a 2011 Chevy Silverado that you...

    On your 2014 Chevrolet Tahoe with tow package there is no under-dash connection port for a brake controller but all the wires are already run.

  • Brake Controller Installation in 2011 Chevy Tahoe
    Beginning with the introduction of the 2007 model year, GM stopped using the connector that was located in the convenience center under the dash for installing a brake controller. Instead, the tow package connection consists of 4 or 5 wires bundled up under the dash that end in bare wire ends that would be wired directly to the brake controller. If you have not yet chosen a brake controller, you can't go wrong with the Tekonsha Prodigy P2, part # 90885. The P2 is extremely easy to use...

  • Location of Electric Trailer Brake Controller Wiring Harness on a 2010 Chevy Suburban
    Mid-way through the 2007 model year, GM quit using brake controller ports. They now use a loose bundle of 4 or 5 wires underneath the dash; red, dark blue, light blue, white, and sometimes orange/brown. I have included links to a help page and a video of a brake controller install on a 2008 GMC Sierra. It should be pretty similar to your 2010 Suburban. The wire bundle usually has a white tag on it.

    GM did not start equipping their trucks with the plug-in connector until the 1999 model year Silverado/Sierra.

Because of the age of the vehicle, the ends of the wires are usually pretty hard to find,...

As far as we are aware the 2014 Chevy Silverados all came with factory 7-ways at the rear of them. Which in that case all you would need to install the brake controller would be the # 3016 harness.

    From what I was able to find, the 2008 GMC Topkick 5500 does not have a port to plug in a brake controller wiring harness. A brake controller will have to be hardwired into the vehicle using a 4 and 7 Way Installation Kit, # ETBC7. Usually, this would require the installation of a 4-Way wiring harness first that would then plug into the back of the ETBC7.

We have a video of a 1993 Chevy Suburban being fitted with a brake controller. Start at the 7:20 time mark on the video and you can see where our installer locates the wire. You should find the wire in a similar location, but use a circuit tester to verify.
