Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 6-pin connector in your vehicle's junction box. The box is located underneath the dash, to the left of the steering column.


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 Tekonsha Brake Controller 3027-P Review

Today we're going to be taking a look at the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers. The wiring adapter is going to ease the installation of your electric brake controller. This is a custom connector and the custom end plugs into the built-in port beneath the dash of your vehicle, vehicle specific. The other end plugs into the back of your electric brake controller so again this wiring adapter is going to really help make the installation of your electric brake controller quicker and easier. This unit is compatible with time-delayed brake controllers like the Draw-Tite Activator I, Activator II, Activator III, and the Tekonsha PowerTrac. It's compatible with proportional brake controllers as well, the Tekonsha Prodigy, the P2, the P3, the Primus IQ and the Voyager. This adapter simply plugs into the six-pin connector in your vehicle's junction box.

That box is located underneath the dash to the left of the steering column. The adapter requires no hard-wiring. It is designed to plug directly into your electric brake controller and snap-locks together for a nice, tight, secure fit. Offers the simplest installation possible and because there are no wires to connect, installation is not permanent so you can unplug and remove your brake controller at any time and securely stow it away. The wiring is all bundled together with a nice protective mesh, so it keeps the wire bundled up so that way you don't have anything dangling down below the dash.

So that's a nice design of the unit as well. That's going to do it for today's look at the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers.

Came in a day early! Exactly as described. It was suggested by other from a Forum and they were right. Plugged right in and easy to mount. I far from home and the person from etrailer walked through order and assured me I would get it drop at the park I was staying at. He was right and made it a day early. All tuned and ready to pull 452719

  • Trailer Brake Controller Installation in RV Built on 2015 Freightliner Chasis
  • There are several different Freightliner chassis types used for RVs, such as the popular XC-series that is often used for Class A diesel motorhomes. This chassis can allow for plug-and-play installation of a trailer brake controller such as the Tekonsha Primus IQ Trailer Brake Controller # TK90160 so long as the RV has a factory tow package. In this case you will use wiring adapter part # 3027-P to connect the Primus to the under-dash port. This adapter also fits 2004 - 2015 Freightliner...

  • Trailer Brake Controller Install Harness Recommendation for 2004 Fleetwood Excursion 39s
  • Your Fleetwood Excursion 39s is built on a Freightliner chassis so the correct install harness you need for the Prodigy P3 part # 90195 is the part # 3027-P.

  • Prodigy Trailer Brake Controller for 2014 Thor Palazzo Motorhome
  • Since your motorhome is built on the XC chassis that has a factory 7-way setup,with the blue brake circuit wire already run for you, I suggest the Prodigy P3 Proportional Brake Controller # 90195 along with the mating wiring adapter harness # 3027-P. The harness allows quick installation at the port under the dash. You will want to find the square connector that will mate with the one in the photo, which is on one end of the adapter.

  • Recommended Brake Controller Plug-In Adapter for 2009 Fleetwood Discovery on Freighliner Chassis
  • The Tekonsha Primus IQ Trailer Brake Controller # TK90160 referenced in your question will work great on your 2009 Fleetwood Discovery RV. This is a really nice proportional controller that will activate the trailer brakes at the same time and with the same intensity that you apply to them in your RV. If the Freightliner XC Series chassis has the pre-wired, factory tow package with a 7-Way connector, you will just need to add the Plug-In Adapter # 3027-P. This adapter will connect to...

  • Wiring Adapter For Brake Controller On The 2006 Winnebago Journey
  • One of the best brake controllers we offer is the Tekonsha Prodigy P3, part # 90195, because it is so easy to install and operate. This will work with electric or electric over hydraulic brakes. Since the Winnebago Journey Motorhome is built on a 2006 Freightliner XC-Series Chassis, the # 3027-P harness is the correct harness to use. If your Winnebago Journey already has a 4 and 7-way trailer connection, one end of the custom adapter plugs into your vehicle, and the other end plugs...

  • Trailer Brake Control Installation in 2007 Coachmen Cross Country RV on Freightliner XC Chassis
  • The 2007 Coachmen Cross Country 389DS Class A Cummins diesel pusher motorhome is built on a Freightliner XC chassis, according to my research. For this base chassis trailer brake controller installation is simple if the vehicle has the factory pre-wired 7-way tow package. In this case the connection point for the controller, such as the user-friendly and reliable Prodigy P3 # 90195, will be under the dash. You will use wiring adapter part # 3027-P to connect the controller to the vehicle's...

  • Recommended Brake Controller For Fleetwood Excursion
  • I recommend our Tekonsha Prodigy P3 Trailer Brake Controller # 90195. This brake controller can control up to one to four axles of trailer brakes. This is an ideal solution for towing small trailers, all the way up to large trailers. Being a proportional brake controller, it'll give you the braking power relative to the braking power that's being applied in your Fleetwood Excursion that's doing the towing, so your trailer stops evenly and smoothly behind you. If you need 7-way wiring...

  • What Brake Controller Adapter is Compatible With 2009 Coachmen Cross Country Motorhome
  • Based on my research your 2009 Coachmen Cross Country is built on a Freightliner XC chassis, so it will use the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 3027-P to connect to the Prodigy P3 # 90195 ONLY if you have the factory tow package on your '09 Coachmen. If you do not have the tow package you will need to hardwire the P3 in by first installing a 4-way (if you do not already have one) like the universal fit # 119147KIT. You would also need to the Universal...

  • Trailer Brake Controller Installation in 2013 Tiffin Allegro Red 38QRA Class A Diesel Pusher
  • For your 2013 Tiffin Allegro Red Class A diesel pusher motorhome, which is built on a Freightliner chassis, you can use one of the excellent Prodigy series trailer brake controllers from Tekonsha, such as their superb P3 # 90195. This is among the easiest controllers to set up and operate, thanks to its advanced feature set which includes storable settings and a large display. If your Red is based on the Freightliner XC Series chassis you will use part # 3027-P to connect the controller...

  • Brake Controller Port Location in 2017 Freightliner XC Chassis
  • Tekonsha brake controller wiring adapter # 3027-P is the specified part for installing a Tekonsha trailer trailer brake controller in a 2017 Freightliner XC chassis with the tow package. Sometimes the correct plug can be hard to spot. There may be others in the same general location. The one you want is black and it should be close to the steering column. I confirmed the part and port location with my contact at Tekonsha. It will be a match for the connector shown in the linked photo.

  • Is Prodigy P3 Brake Controller a Plug and Play Installation on 2006 Freightliner XC Chassis
  • The Multi-Plug T-One Connector Assembly # 20135 is not a fit for your 2006 Freightliner XC chassis; it is a replacement socket for some vehicles that have a factory 7-way already. That said, if your '06 Freightliner XC has the factory tow package the Prodigy P3 Brake Controller # 90195 is a plug-and-play installation. The only other part you would need is the Tekonsha Plug-In Wiring Adapter # 3027-P which plugs into brake controller harness under your dash. The 6-way you have on your...

  • Does Tekonsha Brake Controller Adapter 3027-P Fit 2016 Freightliner XC Series
  • Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 3027-P is indeed a confirmed fit on the 2016 Freightliner XC Series chassis on which your Tiffin Phaeton is built. I checked with my technical contact at Tekonsha who confirmed it will work for you to install a Tekonsha trailer brake controller such as the excellent Prodigy P3 # 90195 or the similar P2 # 90885 proportional brake controllers.

  • Will Tekonsha Brake Controller Wiring Harness 3027-P Fit a 2014 Freightliner XCS Chassis
  • I checked with Tenkonsha and they only show brake controller wiring harness # 3027-P as a fit for the 2004 to 2016 Freightliner SL and XC models. It is possible that they just haven't been able to test it on an XCS chassis yet. Worse case scenario is that the plug will not match what is on the XCS so you would have to hardwire it in. On the harness the white wire is the ground, black is power in, red is input from the brake switch, and blue is output to the trailer brakes.

  • Installing a Brake Controller on a 2006 Coachmen Cross Country 351DS Motorhome
  • The brake controller that I recommend using is the Tekonsha Prodigy P3 # 90195 as it is one of our most popular brake controllers. The reason being that it is very easy to use, it doesn't require you to remember codes, the LCD screen make navigating different options very easy, plus it allows you to store settings if you have different towing applications. To install this on your 2006 Coachmen Cross Country 351DS (which is on a Freightliner XC chassis) you can use the plug-in adapter...

  • Troubleshooting Lack of 12V Power to Electric Trailer Brake Controller on 2004 Freightliner XC
  • The Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 3027-P is the correct wiring harness for your 2004 Freighliner XC Chassis. I recommend removing the harness and testing the pin with a circuit tester like # PTW2993 where the black wire connects to give power to your brake controller. If you don't have power at that pin, then I recommend checking your owners manual for fuses and relays. Unfortunately we don't have wiring schematics or owners manuals for every vehicle,...

  • Installing a Hopkins Brake Controller in a Class A 2015 Winnebago Forza 34T on Freightliner Chassis
  • If your 2015 Winnebago Forza 34T DP has a factory trailer connector, then the adapter plugs into the 6-pin connector in your vehicle's junction box. The box is located underneath the dash, to the left of the steering column. There is not a harness for your Hopkins brake controller, so I recommend the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 3027-P and then cut and splice matching colors and functions. If you don't have a factory trailer connector, then you will...

  • Towing Mirrors for a 2017 Silverado 2500 and Brake Controller Adapter for a 2009 Tiffin Allegro
  • The CIPA Custom Towing Mirrors # CM10950 actually have adjustable mirrors to fit your towing experience. We haven't tested your scenario exactly but if you check out the attached test coure video you can get an idea of what it looks like with a trailer that is just as wide but slightly longer than your trailer. Keep in mind that the camera is attached to the window so it will look a little different from inside the cab of your 2017 Chevrolet Silverado 2500. If your Tiffin Allegro has...
