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.

This is truly a plug and go on my 2015 Forest River Berkshire 400ql on the left side is the plug coming off the harness and you will need to remove the cover on the plug and the harness will plug right in the adapter is a perfect fit and plug right in to the controller took me about 10 min to install the blue plug end is what your looking for about 4” long of the harness tight fit but not to hard

OEM-quality product. Wires, plastic connectors, etc. seem identical to factory harness. Amy E. at eTrailer was great in helping me find the appropriate harness for my application. I wasn't sure if they'd be able to look it up so easily, but their systems are excellent - I told her I had a 2014 Fleetwood Discovery Class A diesel pusher, and she pulled up this p/n immediately. I technically could have used what I already had from prior owner, but I didn't like the butt-splices from the factory pigtail to the existing brake controller pigtail. For $15, it made sense to me to eliminate those splices and be "full factory." I used my terminal pin removal tool to remove 2 currently-unused stubs (key-on, and illumination?) from factory pigtail and transferred them to this new harness. That way, I have direct access to these OEM-supplied wires for any future accessories that may need them.

Installed in 2013 Tiffin 38 RED Freightliner. Was as easy as you said, just plugged in with harness #3027-P.



by:

Did not plug into the supplied brake controller in the kit. Had to cut and splice all of the wires. Might as well have just sent a pigtail instead of an adapter harness.

This harness does install with the part # RED44FR but you have to cut off the black connector and then wire the colors to the brake controller wiring color for color. We dont have a Redarc connector that matches the Tekonsha, so this is the best option and still makes install much easier.



by:

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

This wiring harness adapter was used to connect to my motorhome - Freightliner chassis wiring harness connector and my Tekonsha brake controller with a GM connector. It was a plug together and go! No cutting wires or personal adaption needed!!!!

No problems at all.

Works great! Product arrived fairly fast, although I paid for three day shipping and ordered it on a Thursday afternoon and got it the next Thursday.



by:

Have had this cable and Tekonsha controller in our RV for over a year. We put on roughly 10,000miles towing an enclosed trailer. This cable made the installation of the brake controller a breeze. I think the entire install took less than ten minutes.



by:

We were attending the rally in Sturgis SD and were trying to add a brake controller to our RV before leaving thru the mountains again. We determined the right wiring harness, and were recommended by Tekonsha to contact etrailer for the harness. I spoke with Stacey on the phone and explained the urgency of our need for this part. She made sure it got done ASAP and it actually arrived a day early! We had the controller installed and ready to go right on schedule.

Can't say enough about the service we received. Thanks etrailer and Stacey!!!



by:

I clicked on the button to attach to the factory connector (with Factory Tow Package) on the RV, and it added an adapter to the order. I did not see in the installation notes that you still needed to buy a second adapter to actually make it work. I would think that if you were going to create a package that connects to the factory tow package it would have everything you need. Based on the way this is built I would bet that there is no single adapter from Tekonsha that would function without a second adapter. Seems like a marketing strategy to get more money out of people. For me I paid about xx dollars for a x dollar connector and a few feet of wire, and I still had to do my own wiring. I would not recommend anyone to buy the adapter, it is truly a waste of money and will not do what you expect. Also if you decide to buy both adapters to make it work you are paying about $xx for about $xx in parts, about %xx of the cost of the unit just for a wire with connectors.



by:

This adapter works great! Easy! Anyone could hook it up! The Tekonsha controller works great too! I pull a 24’ inclosed trailer with my race car in it, weighs 8,200 pounds behind a 32’ Winnebago Journey and couldn’t be happier! Thanks



by:
2004 Freightliner XC-Series

Product was as described, well made, fit well and include more than enough wire length. NOTE: CHECK VEHICLE WIRING ... In my case the chassis wire connector was not wired properly. It did not match the chassis manufacturer's wiring diagram and sent the power to the wrong pin-out. Checking saved the controller.



by:

Plug adapter works great and easy to hook up plug and play as they say.

I called several camper sells trying to found a brake control for my motorhome, Freightliner chassis, had no luck. Called etrailer and they knew exactly what I needed, very professional.



by:
2015 Winnebago Journey Motorhome

The product was an adaptor to connect a trailer controller to my Winnebago Itasca motorhome. It fit perfectly and was delivered very quickly. I have used etraier in the past and continue to be satisfied with their products and service.



by:

Great tech advice and service. Installed a brake controller in my fleetwood RV inn15 minutes with adapters. No splicing, plug and play.



by:
2014 Freightliner XC Series

...the Tekonsha Controller cable construction is of OEM quality; well worth purchasing a pre-configured connector for fast connection to vehicle's mating connector.



by:

Very helpful in selecting the equipment I needed for my motorhome. I have purchase from etrailer numerous times and all my transactions have been a breeze. Great folks to deal with.



by:
2014 Tiffin Allegro Motorhome

This worked great. No cutting and splicing wires



by:

Just worked like they said it would pluged right in to Factory pigtail. Took more time to open package then to install . Thanks

etrailer is very reliable for getting the orders out in a timely manner. The website is very easy to navigate and there are always explanations about products so you can verify that you are getting the proper product for what you need.

  • 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 the...

  • How to Connect Prodigy P3 Wiring to a Renegade Valencia RV on Freightliner S2RV Chassis
    The Tekonsha Plug-In Wiring Adapter # 3027-P you referenced is designed for some of the older motorhome models so it doesn't surprise me that the plug doesn't match. With that being said, I'm not sure if you've found the correct wiring connector on your Freightliner S2RV Chassis either, since electric brake controllers only connect to 4 functions. We currently don't have a plug we know that matches your motorhome so I recommend using the universal pigtail that came with your P3 # 90195,...

  • Parts Needed To Install Redarc Tow-Pro Liberty On 2022 Entegrea Accolade Super C Freightliner S2RV
    Rather than use the connector that was supplied from Freightliner, you can use the Tekonsha Plug-In Wiring Adapter # 3027-P that will connect to your Freightliner connector behind the steering post of your 2022 Entegra Accolade. Then the Redarc Tow-Pro Wiring Adapter for Tekonsha Brake Controller Harness # 331-TPH-017 will allow you to connect to the Redarc Tow-Pro Liberty Brake Controller # RED24FR. This will give you a plug and play setup with no need to splice any wiring.

  • 2016 Newmar Ventana Trailer Brake Controller For Existing 7-Way Trailer Connector
    For your 2016 Newmar Ventana with the Freightliner XC chassis, the Prodigy P3 # 90195 you asked from is an excellent choice with easy to use features and no codes to decipher. Because you have the 7-way if it came from the factory you would simply use the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 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.

  • How Does Redarc Tow Pro Elite Install with 3027-P Harness
    This is a good question but the Redarc Tow Pro Elite # RED44FR does install with the part # 3027-P but you have to cut off the black connector and then wire the colors to the brake controller wiring color for color. We don't have a Redarc connector that matches so this is best option and still makes install much easier.

  • Will Curt C51180 Echo Wireless Brake Controller Work on 43 Foot Diesel Pusher Class A Motorhome
    A large motorhome with interior partitions is the one situation where a wireless brake controller won't work well for you. The partitions and distance involved would prevent a wireless controller like the Curt # C51180 Echo from being reliably effective. I'd recommend going with a traditional wired brake controller like the Tekonsha Primus, part # TK90160. From my research, I found that the 2020 Newmar Dutch Star could either be had on a Spartan or a Freightliner chassis. Both have a...

  • 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 into...

  • 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.

    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.

  • Which Trailer Brake Controller Can I Install in a 2013 Tiffin Allegro Red Class A Motorhome
    As long as your 2013 Tiffin Allegro Red did not come with a factory towing package, you can use the Curt Spectrum # C51170 by hard-wiring into the coach. You will need an additional wiring plug to help ease installation, which is part # C51515, as well as some heat shrink butt connectors # DW05745-5 to make your connections cleanly. If you've got the factory towing package, which puts a plug and play harness in the cabin of the vehicle, you will not be able to use the Spectrum . Instead,...

  • Brake Controller Connector Location and Install on 2008 Fleetwood Discovery Motorhome
    My research indicates that your 2008 Fleetwood Discovery 40X was built on a Freightliner chassis. If your motorhome has the OEM 7-way at the back bumper, the brake controller install will be plug and play. From what I found online, the brake controller connector is located behind the steering column. If you're planning on using the Redarc # RED44FR Tow-Pro Elite brake controller you'd looked at, you'll need the # 3027-P harness as well as the # 331-TPH-017 adapter. Plug the # 3027-P into...

Once you find this, I recommend the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3027-P for plug and play installation of the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195. Please note, the plug can be tapped to other wires or even have a dummy plug...

It will consist of the following items: Redarc Tow-Pro Elite Trailer Brake Controller - 2 Braking Modes - 1 to 3 Axles - Proportional, part # RED44FR Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers, part # 3027-P This brake controller comes with a custom wiring harness.

  • 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.

To install your Prodigy P2 # 90885 you'll need to splice the connections using a universal pigtail like # 7894 since there isn't a plug and play connector option for the 2017 or newer Freighliners. Another option would be to use the Curt Echo brake controller # C51180, instead. This mobile brake controller does not require you to test or splice...

    Because of the length of your motorhome and the interior partitions, the Curt # C51180 Echo Wireless Brake Controller wouldn't work on your Class A motorhome. You'll need to use a standard brake controller. Your motorhome has the 7-way trailer connector installed at the rear bumper, so it's already prewired for a brake controller.

    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.
