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.

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

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.

Got the brakes, drums, breakaway, controller and harness installed this weekend everything works great 78261

Ive had the products for about a year now and everything still works great. Now Ive update my vehicle to something new and transfered the brake controller to my newer vehicle. I did watch a Utube video for etrailer on the newer vehicle because it was not a plug and play, so I used my old harness and it works great.Thanks for checking back with me and if I ever need anything you will get my business.

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

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

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

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

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

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

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

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

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

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

The red tow package wire supplies 12-volt power, and connects to the black wire on your brake controller. The light blue tow package wire attaches to the red wire on the controller, the dark blue tow package wire connects...

  • Installing an Electric Brake Controller on a 2005 Chevy Silverado
  • 2005 Silverado models that came with a factory 7-Way plug, meaning 6 blades running around the edge and a round pin receptacle in the center, would not require additional connections to be made in order for the brake controller to function. If your 2005 Chevrolet Silverado did not come from the factory with a 7-Way installed, you will need to connect the 12 volt and electric brake wires under your hood. To do this, you will remove the bracket in the corner that is closest to the...

  • 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,...

  • 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. If you have a Tekonsha brake controller with the quick connector, you would just use part...

  • Trailer Brake Controller Wiring Harness for a 2014 Chevy Silverado 1500
  • If you are looking for a brake controller wiring harness like # 3015-P you selected then you will need # 3016 for your 2014 Chevy Silverado 1500. I have included a link to the installation instructions for you to view. If you do not already have a compatible brake controller I recommend the Tekonsha P2, # 90885. This is one of our most popular controllers because it is easy to set up, easy to use, and its reliable. If you are talking about a trailer wiring harness the only options...

  • Weight Distribution for 5000 lb Travel Trailer Towed by 2004 GMC Sierra
  • When choosing a weight distribution system, ideally the tongue weight of the trailer will fall right in the middle of the effective range of the system. Make sure that the tongue weight figure you use includes the fully loaded and ready to tow tongue weight of the trailer. The weight of anything stowed behind the rear axle of the tow vehicle also needs to be included in the tongue weight figure. If the 405 lb TW figure you mentioned represents the dry tongue weight that does not include...

  • Brake Controller Power Wire Not Receiving Power On 2010 GMC Sierra With All Fuses and Connections
  • It sounds like you still need to make a few connections under the hood of your 2010 GMC Sierra. You will need to locate 2 wires, both wires are red/black with eyelets on the end. One wire is located between the fuse box and driver side fender, the other should be located under the brake master cylinder. On the driver side, remove the fuse box cover, there will be 2 threaded studs that are different sizes, the wires which have different sized eyelets will connect to the corresponding studs...

  • Electric Trailer Brake Controller Recommendation for 2007 Chevrolet Silverado 2500
  • The Tekonsha Prodigy P2, part # 90885, would be an excellent choice for your 2007 Silverado. Chevy produced two body styles that model year, the classic and the new body style. If you have the classic model, you would need to use a wiring adapter, part # 3015-P. The adapter would wire directly to your controller, and then plug into the port located under the dash behind the emergency brake pedal. If your Silverado is the New Body Style, the controller would directly wire into the...

  • Brake Control Wiring on a 2004 Chevrolet Silverado
  • To install a controller on your Silverado, you will need to choose a controller and the appropriate brake controller wiring adapter. I recommend the Tekonsha Prodigy P2 # 90885 and Wiring Adapter, # 3015-P. The P2 is a great unit for the price, and is very easy to install and set up. One end of the adapter harness plugs into the rear of the controller, the other end will plug into the connector located in the junction box behind the emergency brake pedal in your Silverado. I will link you...

  • Trailer Brake Controller Recommendation for a 2003 GMC Yukon XL and 2012 Crossroads Sunset Trailer
  • For your 2003 GMC Yukon XL, I recommend the Tekonsha P2, # 90885. It is one of our most popular controllers because it is easy to set up and use and it offers diagnostics. The P3, # 90195, is a great controller but is geared more towards individual with brake controller experience. It has a lot of diagnostics and features, though and would work well. Both controllers are compatible with electric trailer brake systems as well as electric over hydraulic systems. For your Yukon XL, you...

  • Electric Trailer Brake Controller Recommendation for a 2010 Chevy Silverado
  • The 2010 Chevy Silverado has tow package wiring already routed under the dash, but no port to plug into so you will need to hardwire the brake controller to the factory wiring. The wiring harness on the truck is located below the steering column and to the left of the brake pedal. The bundle of wires will be held together with a white tag that lists the function of each wire. The brake controller only uses 4 of these wires as indicated below. Any additional wires will not be needed and...

If your Voyager has a connector attached to the wires at the back you can use the Pigtail Wiring Harness, # 7894, to connect to the wires on the connector supplied by GM that is similar to the # 3015-S connector we carry. If you wanted a complete harness without splicing you could use the plug-in wiring adapter, # 3015-P. I have added a photo of the connector for the 2005 Chevrolet Silverado...

  • Which Brake Controller and Parts are Need for a 2006 GMC Yukon Denali XL
  • Since your Yukon is already wired with a 7-Way from the factory, all you will need is the brake controller and harness. Brake controllers are universal so any brake controller will work, so long as you have the right harness. The Prodigy P2 # 90885 has replaced the Prodigy # 90185, and is our best selling brake controller. The correct wiring adapter for your Yukon is # 3015-P. I have linked to a video of the Prodigy and # 3015-P harness being installed on a 2004 Chevy Suburban. Different...

  • Brake Controller Wiring for a 2006 Chevy Silverado Pickup
  • If your 2006 Chevrolet has the factory installed 7-way you will need an adapter to install the brake controller. The Tekonsha Voyager brake controller has the wires hard wired into the unit so the Tekonsha Wire Replacement for GM Vehicles, 2003 - 2006, part # 3015-p, would not be the easiest way to install the Voyager. An easier route would be to purchase the Universal Brake Control Wiring Adapter 2003 - 06 Chevrolet, GMC, Cadillac, part # 3015-S, and then wire it to the Voyager brake controller...

  • Wiring a Brake Controller on a 2007 New Body Style Chevy Silverado
  • On your New Body Style 2007 Siverado there is no port underneath the dash, so you won't need a wiring adapter like the 3035-P. There is a bundle of 5 wires taped up together with the following colors red, dark blue, light blue, white and brown. You can find the bundle underneath the dash above the brake pedal. The wiring harness also has a white tag taped to it, which should make it easier to located. We have a chart for how to match these wires up to the wires on the brake controller....

  • Trailer Brake Controller Recommendation for a 2005 GMC Sierra 2500HD
  • When choosing between a time delay and proportional brake controller I will always go with proportional. The reason is that a proportional brake controller will actuate the trailer brakes in proportion to how much the vehicle is braking. This is the safest braking situation. It will also reduce wear and tear on the vehicle and trailer brakes. I have included a link to our brake controller FAQ article for you to view. For your 2005 GMC Sierra, I recommend the Tekonsha P2 # 90885 and...

  • What Do the PL and SH Error codes on the Tekonsha P2 Trailer Brake Controller Mean
  • The PL error code on the Tekonsha P2, # 90885, indicates that there was a power interruption when stepping on the brakes. The SH error code indicates that there is a short circuit at idle. Both of these problems could be caused by a bad ground connection. If you have hardwired the controller to the vehicle, make sure that the ground is connected to the negative battery terminal. The white wire is the ground. Black is for 12 volt power. You will need to test the wiring with a circuit...

  • Brake Controller Wiring Harness for 2008 Chevrolet Silverado Pickup

This bundle will contain a thick blue wire also. Once you have the wire bundle located you will have to hard wire the brake controller to these wires. The thick blue wire on the truck goes to the blue wire on the brake controller, the light blue wire with the white stripe...

  • Wiring a 2003 Chevrolet Kodiak C-5500 for a Brake Controller with Factory Style Wiring Harness
  • When wiring the red brake switch wire on the brake controller you should use a circuit tester to determine the wire that goes hot only when the brake pedal is pressed. If you find a wire that has voltage on it before the brake pedal is pressed and then gets brighter when the brake pedal is pressed that is the wrong circuit and should not be used. If your Kodiak has the prewired connector under the dash for the Tekonsha Wire Replacement for GM Vehicles, 2003 - 2006, then this should be...

  • Brake Controller Harness for a 2003 Chevy Silverado
  • It sounds as if you might have the wrong wiring adapter. The wiring adapter for the 2002 and 2003 Silverado will fit either vehicle, but the order in which the pins are wired is different. Therefore if you have the incorrect one, it will still plug in, but will not work correctly. For the 2003, you would need part # 3015-P, not the 3025-P which is for the 2002. This can easily be verified by using a circuit tester like part # 3808 on the red wire exiting the rear of the controller. If...

  • Is a Brake Controller Needed on a 2010 GMC Yukon Denali Towing a 6,000 Pound Camper
  • Some trucks now come equipped with factory brake controllers. Ford has been doing it since 2005 and GM started in 2006 or 2007. Your Yukon Denali may have come with an integrated brake controller. I would check with GMC to see if your Denali was built with an integrated brake controller. You should be able to call in with the VIN. If your Denali does not have an integrated brake controller, I would certainly add one if the camper is equipped with brakes. It will save wear and tear on...

  • Which Brake Controller Should I use on a 2005 Chevrolet Tahoe with Factory Trailer Connector
  • The part you were looking at includes the harness for Ford vehicles. If you want to use the Hopkins Agility, the part number you would need is # HM47294 and # 47795. It has the plug-in harness for your 2005 Tahoe brake controller port. That port will only be active if your Tahoe came with a 7-Way trailer connector from the factory. I would strongly encourage you to get the Tekonsha Prodigy, part # 90185 and adapter part # 3015-P. It is our best selling brake controller and is one of...

  • Trailer Brake Controller Recommendation and Install Method for a 2008 GMC c5500 Topkick
  • 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. However, there is not a 4-Way harness available for the Topkick, so you will need to clip off the 4-Way plug on the ETBC7 and hardwire...

  • Finding the Stop Light Switch Wire for Installing a Brake Controller on a 1995 Chevy C/K Pickup
  • You will need to use a circuit tester, like part # 3808, to test the wires under your dash. That is where your stoplight switch is located. 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.
