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.

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

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


Have used this for about a year. No problems. Works great with small box trailer and 25 ft. camper trailer.

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

Ordered Curt 1K/10K weight distribution hitch and a Tekonsha Prodigy P3 brake controller, on Friday 11th at 4:00 pm and received them wed 16th at 3:30 pm. Installed brake control same day in about 20 min. installed hitch next day, took about 1 hr to put it together and hook to brand new 25 ft. travel trailer. Brake control was easy to set for right braking power. Left sales yard and drove 140 miles with trailer in tow. Both items work flawlessly without any problems. Sale agent, Lisa D, was very helpful with my order and getting it shipped to me promptly so I could meet A 10:00 pm pick-up appointment Thursday the 17. Great job LISA, Thanks, B Lewis 320227

I sold my 2003 F150 and moved to a 2007 Chevy 2500HD. I moved my Tekonsha P-3 over to the Chevy. This is a well made product. No issues going in. I misread my instructions and didn't need a harness with two plugs. In this model Chevy there isn't a wiring terminal plug. The brake controller is hard wired into the system. I simply cut the plug off that would have connected to the truck harness and spliced into the existing wiring. It took about 20 minutes total. It took longer to make the decision on where to place the controller. :) A harness without the second plug is available at etrailer. 398957

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

This brake controller wiring harness was exactly what I was looking for and it was easy to figure that out on the website. The price was great and shipping was quick. I'm still trying to figure out the wiring connections under the hood on my Chevy. A call to tech support was informative but hasn't completely solved my problem and I'd rather not take it in and pay someone big bucks so will continue to search for my "missing" wires. I've ordered from etrailer several times in the past 5 years and have not been disappointed! 363036

by: Kurt09/18/2014

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 to others. 148187

by: Ed W.11/05/2013

Worked as advertised. I was going to hire someone to install my brake controller as I am getting up in age and not as limber as I once was, until I discovered this product. The installation took me about 30 minutes and worked perfectly. The last test will be to try it on the trailer, but I have no doubts that it will work. I would encourage anyone with basic electrical and mechanical skills and has a vehicle that will accept this type of plug to install it yourself. It was just to easy! 106325

by: Rob W08/12/2015

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 already owned the Prodigy 2 controller and was using it with a vehicle different than my 2004 Yukon. I recently purchased a travel trailer and needed to add a brake controller to it. The installation of the Prodigy 2 controller was simple and all I had to do was order the cable 3015-P for the controller connection to the vehicle. It was just plug and play, very simple.. It took about 20 minutes for total installation time. 363028

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

Everything was plug and play as advertised. I used the videos posted by as installation instructions since none are provided with the item. The link for the video was easy to find on the etrailer web site. Total time to install was less than half an hour, counting getting out the needed tools. My 2005 Tahoe needed the addition of a 30 amp breaker in the under hood fuse panel. 306140

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

Perfect fit, correct cable and correct length works fine. I bought the cable to go along with the Tekonsha Primus IQ Trailer Brake Controller. I like the brake controller and find it easy to use and very easy to install. One note, don't forget to add that fuse to your engine area fuse block. It is needed to power the controller and other things. 353653

The 3015-P is a simple plug and play wiring completely eliminated the need for cutting and soldering or crimping wires...I was able to install the brake controller in less than 15 minutes.

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,...

  • Installing a Brake Controller on a 2006 Chevy Silverado 1500 with Tow Package, Is it Pre Wired
  • As long as your 2006 Chevrolet Silverado 1500, has the factory 7-Way tow package wiring at the rear of the vehicle all you will need is the Draw-Tite Brake Controller with Wiring for the 2006 Chevrolet Silverado, item # 5100-3015-P, which includes the # 5100 brake controller and the # 3015-P wiring harness needed to install the brake controller on your truck. The # 3015-P adapter will plug into a port in the power distribution box under the dash on your truck. If you do not have a factory...

  • Where is the Brake Controller Port Located on a 2005 GMC Yukon Denali
  • The brake controller port on your 2005 GMC Yukon Denali will be located in the black junction box, which is under the dashboard and to the left of your steering column, right above the carpet. The plug in point will be the second port from the left, on the top row. I have included a link to instructions for a brake control wiring adapter # 3015-P that plugs in at this same point, if needed. If you do not already have a brake controller, I would recommend the Prodigy # 90185,...

  • 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...

  • Location of Brake Controller Port on a 2003 Chevrolet Silverado 2500 HD
  • If your 2003 Chevrolet Silverado 2500 HD has the factory installed hitch and a 7-Way connector, then all of the wires for the brake controller have been run. The factory brake controller port is located in the black box underneath the dash on the drivers side, to the left of the brake pedal. Usually a brake control adapter will be included in the junction box. If an adapter is not in the junction box you can use the Draw-Tite Universal Brake Control Wiring Adapter, part # 3015-S, for...

  • Brake Controller Installation on 2007 Chevy Tahoe
  • The tow package wiring is located under the dash above where your left knee would be as you were sitting at the wheel. Look for a wiring harness with a white tag on it. GM no longer has a connector, you'd just need to wire the controller directly to the tow package wiring. 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...

  • Weight Distribution Recommendation 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...

  • Installing a Brake Controller on a 2014 Chevy Suburban
  • The 2014 Chevy Suburban does not have a place to plug in a brake controller but it does have a tow package wire bundle that you will use to wire up a brake controller. The wire bundle is located up under the dash to the left of the steering column. It should be held together with a white tag which also lists the wire functions. I have included a link to our help article that explains the installation. There may also be some connections that need to be made under the hood to make everything...

  • Brake Controller Installation on a 2010 Chevrolet Silverado 1500 Crew Cab
  • More often than not, the connections under the hood of your 2010 Chevrolet Silverado 1500 will need to be made to complete the installation for a brake controller. I have heard of some occasions where these connections were made at the factory, but it would be wise to double check. Once you have the brake controller wired to the brake control harness in your cab, check for the brake control wire and the battery charge wire under the hood. The brake control wire will be located to the...

  • 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...

  • Trailer Brake Controller Wiring For a 2005 Chevy Suburban with Factory Tow Package

I have included a link to a video showing a typical installation on a similar vehicle. The brake controller wiring functions are: White = Ground Red = Input from brake switch Blue = output to trailer to brakes Black = 12 volt power But since you have a simple plug in option, you will not...

  • What Size Fuse or Circuit Breaker Should be Used for Brake Controller on a 2006 Chevrolet Silverado
  • 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. In applications with 6 to 8 brake magnets or more, more amperage is required to activate the brakes properly so the time for the amperage spike...

  • 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...

  • 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...

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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

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...

Under the hood, on the drivers side towards windshield, there is a bracket you will need to remove to gain access to the Accessory Fuse Block and lower fuse housing.

  • 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...

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.
