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 junction box beneath your vehicle's dashboard.
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.

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

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

Great brake system, made my life on the road so nice.I would not hesitate recommending this product to anyone...Thank you for your prompt and courteous service.etrailer ROCKS!!! VAT cheers 58534
Application: 2004 Chevy Tahoe LT / Pulling RV Camper My first ever review of anything purchased online and I figured this one really had merit to deserve the extra attention in giving credit where it's due.. Easy and efficient online ordering processes, excellent customer service and the follow-up email after the sale and delivery of the product was the icing on the cake! You guys' have really got it together over there and I'll be ordering from you again very soon! Thoroughly impressed with the fantastic O.E.M. quality connectors and wiring harness of this product! Perfect length, perfect fit and installed just as quick and easy as the product's description and related installation videos have shown. Thanks again for the outstanding customer service and superb product quality! "I'll Be Back!" 144028

I watched the video on how to install on a similar vehicle. It took me about 20 minutes to install because I had to find my tools and wire ties. The installation was simple. 158200

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 purchased the Prodigy P2 and the corresponding wiring adapter item number 3015-P. Installation was very straight forward and simple. Only issue was after everything was installed correctly and triple checked. The brake controller would not connect to the trailer and was throwing a "NC" error code. Trailer lights worked, proving connectivity between factory plug and trailer and also a good ground. After troubleshooting for over an hour, re-seating connections, and everything else I could think of, I left everything alone for the evening. Next day, turn the ignition switch on and the controller was working perfect...and has for over a week. No idea what the issue was/is but it hasn't arose since. 143433
Outstanding sale. Good price, smooth transaction and most importantly knowledgeable/good communication. I'll be back... 163657

I purchased a newer truck and wanted to transfer the trailer brake controller from my old truck to this one. I installed the controller and connected; lights came on but brake would not engage. E-Trailer has always been my goto for trailer parts so I gave them a call. Mark M helped figure out I needed a different harness between the controller and the truck connection panel. I placed the order thru him and recieved it on time as usual. The part was a perfect fit for my application and it took all of 10 seconds to install; it plugged right up to existing connections. I have always recieved world class customer from E-Trailer and this occasion was no different. Great place to shop! 155323

I purchased the item 3015-P along with the Tekonsha Prodigy P-3 trailer brake controller. The instructions were excellent as well as the etrailer online video instructions, which made the installation a breeze. I did call about a question I had about the Prodigy P-3 and my call was answered in a very helpful and very friendly mannor. Shipping was remarkably fast as is etrailer's service. And their prices are great too. I really enjoyed doing business with these folks and I will be a repeat customer. Robert M. Littleton, Colorado 72141
Excellent product! Plugs right into truck and is well assembled. My brake controller was a different brand, so I cut the Tekonsha plug off the end of this adapter and wired it straight to my controller leads. Using the wire sheath that came with it, I covered up my splice, tucked it under the dash, and it looks like a factory installation. I've wired a lot of brake controllers from the battery, through the cab, and out the back. This type of adapter is definitely the better way to go if you have the option. 151838
by: Michael E.08/23/2014
Well, I haven't used the product much yet other than to take the camper out for a test drive and set the brake control. All seems well thus far. I wil say though I am very pleased with etrailor's customer service. Very good service and prompt delivery - unlike the other place I purchased my brake assemblies from. Had I known etrailor has brake assemblies prior to purchasing from that other place, I would have purchased here instead. Wish I had. I know now and will definitely recommend etrailer.com to others. 148187

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

The Prodigy 2 controller is just what I expected. Installation was a quick and easy. Plug and play doesn't get much easier. I used the metal bracket on my installation due to the fact that it allowed me to use the holes previously used for the old controller. I hope to be back on the road using it for my 26' low boy equipment trailer and 38 ' fifth wheel travel trailer soon. I would give it an excellent rating but I haven't gotten to use it yet. 114335
i didnt take any pictures of the installing but didnt expect it to be as simple as it was it was quick and easy just plug it into the femal plug under the dash then into the p3 set it up and ready to go withen about 45 minutes i pul a 20 foot camping trailor with a 97 silverado classic trailor weight 8589 pounds and this p3 dois a great job going down montegle mountain and it is a steep mountain. sign tommy 69464
The install was quick and easy with this cable. The cable was too short for me to reach the desired location of the controller, though, so I simply cut it and spliced on the connector pigtail that was included with the controller. I used a similar kit when I installed a brake controller on my Ford and it was long enough. On this Chevy it could have been a foot or two longer for the most flexibility. 69888
by: Scott Y06/01/2015
They should add some finger screws since you may not be able to get a screwdriver between the mounting bracket and your center console, but other than that, installation was a breeze and it works extremely well. It took me longer to locate the plug in a GMC vehicle than it did to install the controller. The plug and play wiring harness is well worth the small price you pay for it. 199558

I ordered the pre-formed wire harness with a Tekonsha Prodigy P2 trailer brake controller. I was glad I ordered it, instead of relying on the included wire harness, as I did not have to make up the truck end, and it plugged directly into my Chevy truck, without any modifications. I highly recommend buying a wire harness specific to your truck instead of having to make up one end. 231703
Got it on time as Karen had promised yesterday when I ordered it, installed it in less than a few minutes and works great, Karen was courteous and very knowledgeable about the product and to complete the great experience she followed up on the delivery and sent me here for more info on what I bought. Karen you should get a raise. What a great customer service. Thank you 175208

I ordered this product on a Saturday and received it on a Tuesday. Monday was a holiday,so really surprised to get it so fast,since I had only paid for the standard shipping.The web site is really good, especially with the video that showed me how easy it is to install. I have installed it,but I have not had much time to use it yet,but I am sure it will be good. 116917

Ordered a Tekonsha to General Motors Wiring Adaptor and from the beginning of the product search on the etrailer website to receiving the part, this was an excellent experience. The website is very easy to navigate and the technical advice outstanding. The price was also great and I received the part in just a few days. Great place to shop for trailer stuff. 99874
The 3015-P is a simple plug and play wiring harness...it completely eliminated the need for cutting and soldering or crimping wires...I was able to install the brake controller in less than 15 minutes. I recommend the purchase of a wiring harness with any brake controller. The 3015-P is a quality product and well worth the money. Thanks Rick 6459
by: Reed A.05/21/2012
Wiring harness and brake controller are working great and install was a breeze. The only thing that would have helped would be to include a install diagram for the wiring harness as to the location of plug in on my 04 Chevy Tahoe. I had to look it up on you tube. Overall fast shipping, great tracking of shipping, and great product! Thanks. 41184

Very good conversation with sales person. Got correct equipment ordered. Received actuator and pigtail in very reasonable time. Found proper plug in inserted pigtail connected actuator . Easy programming. Mounted actuator in easy to reach position on dash. I would definitely recommend these people for any of your trailer product needs! 243373
The plug-in GM wiring adapter worked great on my 2005 Chevy Suburban Z71. Although my truck came with a brake controller wiring adapter, the idea of plug and play without additional work was a good idea. The unit supplied was the perfect length and has a mesh braid encompassing the wires. It was well worth the little extra cost. 122485
by: John S.07/21/2011
Plugged right in to the socket and into the controller. Unfortunately the socket is in a very inconvenient location for a large person to get to. If the instructions suggested using a mirror and light it would have gone faster. The tow vehicle socket is located where you can see it or reach it, but not both at the same time 19818
As usual our order arrived very quickly and all of the items were in excellent condition upon arrival. The brKe controller and harness went in perfectly. We are looking forward to trying it out with our trailer. Thanks again for all of your help with all of the parts needed to get our truck ready to tow our new trailer. 222563

The brake booster and GM cable was shipped and received very fast. Installation was easy on my 2005 Silverado that has factory tow package. It only took me about 30 minutes to install and set up. Tested with my popup camper and it worked flawlessly, would definitely recommend etrailer and this brake booster. 205982

My product arrived as scheduled and I was notified throughout the process of what was going on. The only thing that could have made the buying experience more enjoyable was if my items were free. I will definitely go to etrailer in the future for all my trailering needs. No more ebay for trailer stuff. 97545

I was amazed at how easy the wiring harness and controller installed on my 2007 Chevrolet Silverado LT. I just had to remove the cover to the left of the brake pedal and plug it in, then to the controller. I tied up the wiring harness and I was done. Now waiting to adjust my controller to my vehicle. 30319

Wow this worked great. Got . The 3015 p w out ring harness and the Tekonsha p3 controller in the mail ran out to my 03 escalade and as easy as plugging in a lamp everything worked great. I cannot sat enough about trailers service. I ordered on a Sunday night and it was at my door on weds. 113936
The Brake controller was easy to install and worked great. It made a big difference in slowing down my 7800 lbs. trail trailer. Thank you for such a quick dilivery and updates on tracking my items. I will do business with you all again and will recommend you to my friends. Thank you, Craig. 73422

This harness fit great. Made the installation quick and easy. I mounted the brake controller mounted under the dash right below the radio. The harness was just the right length to get to this point. The assistance from Wayne was great. The instruction from etrailer worked perfectly. 172740
by: Robert Young03/08/2012
Product is excellent and exactly what was expected. I wasn't too sure what harness was needed to fit my truck, and a quick phone call to an actual person (thank you Rose G.) got me just what I needed. Products and prices are great, service and shipment, even better.. Thanks again. 33256
by: Frank S.02/19/2015
I recieved my order promptly and as promised. However I have not had the opportunity to install the brake controller as of yet. Based on the very detailed instructions it should be fairly easy to install and set up. I am very impressed by the service I received from etrailer 175295
by: Harold L.05/22/2014
