Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.
Features:
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 of Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers - GM
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're going to review part number 3025-P, this is the Tekonsha plug-in wiring adapter for Draw-Tight and Tekonsha electric brake controllers. Now this part number is a custom fit part number, it is designed to fit the Cadillac, Chevrolet and GMC vehicles starting in 1999, it does fit a wide range of vehicles so what I would recommend is to go to our website, use our fit guide, put in your year and model of vehicle, and it'll tell you it this part will work for your application. Now this wiring adapter will ease the installation of your electric brake controller. One on end, right here, you can see it's a custom connector. This is designed to plug into your factory brake controller connector that's usually beneath the dash of your vehicle. The other end right here, this will plug into the back of your electric brake controller. This wiring adapter is compatible with time-delay brake controllers by Draw-Tite, and it's compatible with proportional brake controllers by Tekonsha, like the Prodigy, Prodigy P2, Prodigy P3, Primus IQ and the Voyager. Basically the way this would install, here's an example I have a Prodigy P3 right here. You can see the very back has the plug-in, so just take your plug-in, push it in, you can see it snaps and locks into place, and then your other end has the custom connector on it.
This you would just locate your factory brake controller port on your vehicle, it's usually under the dash, plug it in, and then you're all ready to go. And then when you just want to remove your break controller, just lift up on your bracket, and then you pull it out. And then it's easily removed. That should do it, for review on part number 3025-P, the Tekonsha plug-in wiring adapter, for Draw-Tite and Tekonsha electric brake controllers. .

etrailer's instructions and videos are awesome. installation was a breeze UNTIL I needed to locate the brake signal wire (cold side of brake switch) on my 1999 suburban. What a pain. the switch is not very accessible let alone there are a ton of white wires under the dash --along with an alarm. Long story short, I found this in a GMC forum and it saved me big time: "Under the dash, next to the emergency brake is a black convenience box. At the bottom of the box is the letters GRN, next to that is the letters NAT with a small recessed box with two male spade connectors. The spade on the right goes to the brake switch. The wire from the brake controller is terminated there." Using the supplied probe tester I was able to verify this and finished up my installation. The Tekonsha Prodigy P3 controller works great. 112192
The Tekonsha Prodigy P3 controller is still working great. I cant believe i didnt get one sooner. Easy to adjust on the fly and no issues at all.

Bought a new Primus IQ brake controller but it only came with a pigtail wiring that had to be spliced into my '01 Suburban. Ordered the direct fit wiring pigtail from etrailer.com and couldn't be more pleased! It literally took me less than 10 minutes to plug in the wiring and mount the brake controller. Excellent customer service and very fast shipping! The kind of shopping experience that causes repeat business. Thank you etrailer.com and customer rep Lexus for making everything so simple! 203301
Excellent. No problems at all!

The hitch and controller was installed on a 2002 Chevy 2500HD. It took roughly 15 min to install the Tekonsha P3 Brake Controller, plug it in and program it. As far as the B&W Turnover Ball Hitch, I cut the hole in the bed and cut the heat shield out the day before while I was waiting for the hitch to arrive. The next day my parts arrived, I laid out all the parts to make sure everything was there and then started the install. I didn't want to cut the 1"x1/2" notch out of my fender well to get the angle iron in so I spent about 15 min. trying to get it up on top the frame from underneath the truck. A waste of time. Do like the instructions say, cut the notch and slide it straight across the top of the frame. It will save time and aggravation. After getting both braces in place I ran a piece of rope down thru the hole and pulled the hitch plate up into place and tied it off. I installed all the bolts finger tight, put the side plates on and tightened everything up. It looks nice and I saved myself a $435.00 installation fee. With out a lift and without taking my rear tires off it took about 3 1/2 hrs. to install by myself. The only thing I want to say to B&W is don't place the heavy metal hitch parts on the booklet with the packets of Lithium Grease in it, they bust as the picture shows. Last but not least, thank you Sherry for all your help with my order and getting it to me quick in such short notice. I really appreciated it. 353453

by: Matthew07/21/2018
Makes installation a snap to wire up. Also makes it convenient you can use between other vehicles pretty much makes it a plug and play. I have 3 of them in our vehicles and there all the same set up. So if one did go down i can take one and swap it out with another one. Just need another mounting bracket and you can have 1 controller for 2 vehicles. 544434

Hello I hooked it up and it will not power up, any suggestions? 588610
If your 2002 GMC Sierra does not have a factory towing connector you will need to finish the wiring for a 7-way plug at the rear of the vehicle. If you have a bundle of wires at the rear of the vehicle you will need part # PK11898
Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness and Mounting Bracket
$30.95. If you have a plug at the rear of the vehicle with a cap you will need part # 30955
Replacement Custom Multi-Tow 7-Way and 4-Way Trailer Connectors
$29.99 instead of the PK11898. If your 7-way plug is already wired in and you still do not have power you probably need to activate your towing package by connecting two power feeds to your fuse box. These two power feeds are located under the hood and they will need to be connected to two posts in front of the battery. The first power feed is located on the wiring harness that runs below the brake master cylinder and booster that will need to be connected the post on the battery. You can locate the next power feed in a wiring pigtail between the fuse box and the inner fender well on the drivers side that will need to be connected to the post on the battery. I have attached a video please skip the brake controller installation until you get to 3 minutes 45 seconds in the video.

1 year to the month, my Tekonsha controller has been flawless. got into a much heavier crosswind once that the Suburban could handle, and reached down to the controller and hit the Trailer Brakes..... worked like a charm, straightened us out immediately. I really like the variable power feature, I can change it depending on conditions as to how much trailer brake is needed for just creeping along..... my old controller was a "set it once" and that is it.... so the trailer always hit hard first. not this one, it is extremely good at sensing how much brake the trailer needs. 581279

So far so good. The last one I ordered fit perfectly so I'm trying again for a different vehicle. Same trailer brake controller and wiring harness. 498778
by: Noah04/20/2018
See review for the brake. :) This wiring kit makes it so you can install it with almost no eyes or hands. Yes I needed them both but it took all of 45 seconds to attach to the brake controller and then into my 1999 Chevy Silverado 2500 panel. Best product EVER! 498509

I have a 2006 Chevy Silverado 2500 hd and had to move a wire into a different location on the connector in order to make the brakes work. Moved the blue wire up to the top right location. 496388
The 3025-P is a fit for 1999-2002 Chevy Silverado/GMC Sierra. For a 2006 model, youll want to use the 3015-P. As you found, moving the brake output circuit wire will make the 3025-P work on your vehicle.

Installation was a breeze thanks to the wiring adapter that was fit exactly to my truck. This unit works great. It has settings for multiple trailers. There is no off button. It goes into a sleep mode after about 15 minutes. The drain on the battery is insignificant. I recommend disconnecting it though, if you are not driving your vehicle every day. As always, etrailer was super easy to deal with. I ordered this at about 7PM CST and it was ready for shipment that night. They are my go-to company for anything I need for my boat trailer and RV. 474167

I like this controller, and the installation was pretty straight forward. I purchased it because the larger trailer I bought had brakes, but I have since only needed to use it twice, so I haven’t had enough experience with it to give an excellent rating. I had no issues when it was used. 451424
