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 built-in harness beneath your vehicle's dash.
Features:
For most applications, the factory plug is located beneath the dash, near the center console. If you have a Ford full-size van, the harness is underneath and to the left of the steering column. The Ford Explorer and Mercury Mountaineer have 6-pin connectors behind the glove box on the passenger's side. On a Ford 2010 Flex, the connection point is under the front edge of the dash directly below the steering column. On a 2013 Ford Explorer, the connection point could be behind the driver's side kick panel. On a 2014 Ford Explorer, the brake controller port is located by 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.

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 built-in harness beneath your vehicle's dash.by: Stephen11/25/2017
I haven't towed with the it yet. But installation on my 2007 Ford F150 was pretty simple. The plastic panel I attached it to had steel behind it. So I removed the plastic panel, mounted the bracket, then trimmed the excess length off the screws, and reinstalled the panel. The wiring harness plugged right into the truck's plug under the steering wheel. It seems like a great product, and having the specifc wiring harness for my truck made it simple to install. Sheila was very helpful too. Thanks. 454728
Ive been using it now for a year. It works great!
by: Brian L05/04/2014
Plug and Play...great product! The researched paid off. Installed it today and was driving off with trailer in 30mins...works perfectly. 128838
Solid, read to start another year of pulling family camper!

I purchased a Tekonsha Prodigy P2 trailer brake controller based on my satisfaction with a previous puchase for another vehicle a year ago. Your representative (Kat) was professional and a good communicator. I am a satisfied, returning customer and will purchase from etrailer in the future. Thanks for the good products and excellent service. Sincerely, Steve 211211
It works well as intended. Thank you for your excellent service and follow up.
by: Frank H.10/29/2012
so simple to install, plugged right into factory harness and brake controller 58317
Thanks, everything is good. I have only pulled a trailer twice but everything performed as it should
by: Joseph A12/17/2012
Installation went flawlessly, with the quick connect and the car being “prewired” from the factory I was done in 15 minutes. I have not used the controller yet but this is my second Voyager, I have the same unit installed in my Ford Ranger, and have used that one without incident. Thanks etrailer for your fast prompt service as always. 61656
after a couple of years use this controller still continues to deliver smooth consistent trailer braking, I would recommend this controller to anyone who needs a reliable controller to work the first time every time.

I just installed the Tekonsha Primus IQ controller and used the plug adapter 3035P to hook into my wiring harness on my 2013 Itasca Sunstar 26 HE. The chassis is a Ford F53 with a V10 motor, in case some one needs any reference to hooking into their motorhome wiring. Its was installed quicker than making my coffee! 124541
Question? Where did you find the factory plug? I will be installing Primus IQ in a 2014 Windsport which is also built on a Ford F53 chassis. Thanks.
-- comment by: John L - 04/12/2014John the plug-in on my 2013 Itasca for the adapter plug 3035P was on the left side of the steering column. It is a grey male plug with four wires very easy to see. Hopefully yours will be in the same position. Good-luck
-- comment by: Bruce - 04/14/2014Thanks for coming back to follow up with us!

I order the Tekonsha Brake controller and cable for my 2012 Ford Explorer. The customer service was outstanding. No automated answering systems. I was speaking with a human being in seconds and she was extremely knowledgeable of this product and the installation. I received the product in 3 days just as promised, received a confirmation, email, and email that the product shipped with tracking information, and an email indicating the product was delivered. I’m overwhelmed by the customer service. The product just as advertised is great it hooked up in about 5 minutes the cables fit and does an excellent job with my trailer. I haul a small stock car to and from the track and this controller is extremely easy to use and have very advance capabilities. The installation was on a 2012 Ford Explorer with the tow package. The wire to connect the brake controller is under the dash right next to the hood release level. Tow screws and an odd plastic push on is all that hold the black plastic cover to gain access to the Explorers cables. Again thank you to the outstanding customer service 37244

Plug and play installation. Doesn't get any better than that. Well worth the money. 139809
Still very happy with everything. No regrets.
by: Robert H.03/24/2015
Works great. I plugged it in flipped the switch and walla it works, great. Had really fast shipping and received in a few days. It is so worth getting the plug in type in lieu of wiring. Also, etrailers had a video that showed me clear step by step instructions. Will definitely order from them again. 180654
Still going strong. Great product durable and lasts.
by: Roy S.03/27/2015
The pigtail worked perfect, the one that came with brake assembly required wire match ups and was excessively long. This was a perfect fit and solution. Thank you for taking care of the shipping problem. 181130
Fantastic
by: Stan K03/12/2017
I ordered the trailer brake adapter harness for my 2010 full size Range Rover. It fit great and its well made to do the swap, for others that will read this here is how. I found the brake connector in the truck was hidden behind the fat harness thats next to the inside left kick panel, just behind the hood release panel By pulling on the OBD 2 wire harness, I found it was tied to the OBD harness. Some say that the connector is on the left side of the steering column , in my truck is was on the far side of the fat harness so it was hard to see. I had to remove the left side console, I removed the screw, then pulled the bottom of the wood panel towards the left door, the 2 pins released, then the panel slides to the rear of the truck to dislodge the top pin. 5 screws secured the lower panel , remove the lamp ,unplug it, then remove the OBD 2 connector from its mount , slide the gray collar to the left kick panel then the harness pushes up out of its holder. Plug in your new adapter harness for your trailer brake controller, Assemble is the reverse of taking it apart. in the picture the new harness is connected to the gray connector 351855
This harness works as it should, a good product,
by: Geoff G07/03/2013
Super easy install on 2013 Explorer Sport- just plugs in! Only reason I docked it one rating is it should have come with a couple of cable clamps and screws to hold the excess cable neatly & safely under the dash. I had to buy them separately - see photo. 87271
Continues to work perfectly!
by: Elliott L.08/09/2017
Fit our 2002 F-250 perfectly. Had plenty of length to route it where we wanted. 418085
Working perfectly.
by: Paul Chick08/18/2015
The right harness- couldn't find it elsewhere; prompt shipping 220091
All the products work very well. We traded trailers and made adjustments to the hitch accordingly. Perfect results! The brake controller required only slight adjustments for timing and intensity. Everything works beautifully. I recommend you to all who inquire about these products, and your services with very competitive pricing!!

Received my Tekonosha Prodigy P2 electric trailer brake and free connector for my 03 Ford Expedition in a very timely fashion 3-4 days after ordering. The following day I received an Email from George J.,confirming delivery, there was an installation video included for my vehicle (I was going to take the brake to my mechanic for installation). I installed the brake in minutes, thanks to the video. Saved me some bucks and time too!, What a great touch!, I would recommend etrailer.com to anyone with a trailer. Thanks for the great service and the video. .A happy customer... 180838
All is well with product...

My F150 had an OEM 4 pin trailer plug and hitch. The 118242 - 7 pin connector with wiring harness is the ticket. The hardest part of the install was dropping the spare tire. The plugs connect directly to the factory plugs and the harness length is the correct length. The 3035-P brake controller connector harness was just as easy. Plugs right in to the OEM plug next to the ECM connector and the other end into the brake controller. The PK12711U-26 - 7 pin bracket and hardware kit fastens directly the OEM bracket that is on the hitch. My truck had an OEM 4 pin trailer towing set up with the hitch. The OEM hitch had the bracket welded on it to attach the 7 pin mounting bracket to it. These kits make this install very easy and professional looking. If I have one complaint, the hardware kit to attach the 7 pin connector bracket is set up to fasten the bracket directly to the bumper with 2 - self tapping screws provided in the kit. The kit also includes 4 #12 machine screws with toothed washer nuts to attached the 7 pin connector to the bracket. This is fine if your truck hitch doesn't have an attaching bracket welded to it. The kit should included in it 6 #12 machine screws and nuts along with the 2 self tapping screws. Since my OEM hitch actually had a bracket welded to it to attach the 7 pin bracket to it, I had to use two other #12 screws and nuts to attach the 7 pin bracket to the OEM bracket on the hitch. Not a big deal, just a thought. It took me about 2 hours, start to finish to install the 7 pin connector, trailer controller, and add the two relays in the OEM relay/fuse box under the hood. I highly recommend these kits. 322340

Product was exactly as indicated. worked perfectly for my installation; quick snap and we were in business. Price very reasonable; delivered promptly as scheduled. My installation was a Tekonsha Prodigy-2 into our Damon Challenger motorhome. The motorhome was a 2009 built on a 2008 Ford F53 chassis, so this created a little trouble in identifying the correct part, but etrailer's tech support was on the ball. Tech even provided information that clearly showed where the F53's connector was located under the dash - which was exceptionally helpful since it is very hard to find. Have purchased many parts from etrailer and none have disappointed. Always the first place I look for any trailer wiring parts. 281764

I'd ordered the Tekonsha Prodigy P2 Proportional Trailer Brake Controller (1 to 4 Axles ) on a Monday with a Wednesday delivery date of two days, as I'd specified. I have a Lincoln Navigator that had the factory installed heavy tow package. I had also ordered the adapter connector for Prodigy P2 controller to the Navigator's factory plugin. The entire install took me 15 minutes. I found the video review of the controller quite helpful as it demonstrated how to static set the controller's setting before drive trials and how to set the "boost" settings. Good price and very easy to install. 557090

Very robust product. Great customer se rvice. 574805
by: John G.07/02/2014
The product turned out to be excellent. At first I thought it was totally wrong for my application, but through the help from a very knowledgeable tech support group at Tekonsha I was able to correctly install this wiring harness. How difficult can it be? I asked myself that until I learned that on my 2008 Ford E-450 motorhome chassis, Ford had TWO receptacles that the wiring harness fit into. Only one of those receptacles was connected to the trailer receptacle - who knows what the other one was for. The only obvious difference was that one was gray and the other was brown. The trick was knowing where to find the brown one and the Tekonsha folks came through with the location. I can't say enough about the great folks at Tekonsha. The wiring harness is very well made and is long enough to provide flexibility in locating the brake controller. It is truly plug and play. Etrailer was terrific in ordering, shipping and I received the order quicker than I expected. Packaging was excellent. I will definitely place another order with etrailer.com! 138847
No issues a year later. Out of site out of mind. works great.
by: Wayne11/14/2014
This is the first trailer brake controller I have ever purchased or used so I don't have any past experience for a reference. However I think I hit the jackpot with this. The installation was easy and took me no longer than 15 minutes after a quick review of the installation instructions. I have a 2004 F150 and along with the Tekonsha Brake Controller I purchased the Wiring Adapter which made the installation very easy. Took it for a test run and it works awesome. Good product. 160902
by: Brad10/04/2018
Assumed it worked OK, as I did not wire it into the vehicle. Didn't hear anything negative from the installer tho. 571572

great product 562320
by: Mark09/05/2018
Install on my '06 F150 was as easy as drilling two small holes for the mount and plugging in the adapter kit to my factory tow kit wires. I'll update this if any problems arise when i actually use the brake controller. Can't be happier with the install though. 562116
by: Michael09/01/2018
This connector worked on my 2007 Ford F150 perfectly. The vehicle connector was right next to the brake controller. It took just a few seconds to hook up with this connector. Excellent! 560678

Important note: There are 2 plugs behind the parking brake that this adapter fits into. For my 2003 Ford I used the BROWN plug, not the GRAY one. Works great. 555485

by: Justin08/17/2018
Yes, the controller came with wires i could have easily spliced in. By why? For $10 plug and play capability, worth every cent. It took longer for me to type this review than it did to install my brake controller. 554654
