Install your Curt electric trailer 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 port beneath your vehicle's dash.
Features:
To install your Curt electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.
This adapter plugs into the port on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, and it is taped to another harness near the emergency brake pedal.
No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

Using the Curt wiring adapter, installing the Curt TriFlex brake control in my 2006 Toyota Tundra was simple after watching your video. Very pleased with everything I ordered from e trailer.
Yes I received my order and installed the brake controller. All seems to be
fine, although I have yet to tow with it yet. Here are a couple photos of
the installation in my 2010 Toyota Tundra.
Fit perfectly on my 2023 Toyota 4Runner
Installed on 2011 Toyota Sequoia - Plug and play as advertised.
Well that was the easiest thing I've ever done on a vehicle. The info on the etrailer site was instrumental in this being a quick plug-n-play mount of the Curt brake controller. I watched the two minute video and 10 minutes later I had a new brake controller installed in my 2010 Tundra.
Teconsha P3 is an excellent brake controller.
Even better was the customer service from etrailer....I had an issue with another model, called etrailer, and they made it right. No questions asked. Will definitely shop with them again. Thanks, etrailer! -wade

Love the Tekonsha. Will not buy another Curt. Thanks for asking. And e-trailer was great, especially dealing with the dysfunctional Curt. Thanks.
Perfect cable for my Tundra!
The adapter for connecting the trailer brake controller arrived earlier than scheduled. It enabled a quick and easy plug and play connection of the controller to the vehicle.

Worked perfectly - plug and play
Fast shipping! Great product for this price. My 2012 Tundra has airbag underneath steering column so I mounted brake controller just left of area.....perfect! Works like it came stock.

The EOH braking system works perfectly. You are my supplier of choice if when I need additional trailer parts on the future.
plug in to factory harness without cutting orvsplicing. saved a couple hours working under dash. worth the cost. unfortunatelt harness adapter, brake controller or some other fault is causing random trailer brake lock-up without applying vehicle brakes at highway speeds, a scary event. unable to troubleshoot as winter snow then heart health issue continue to prevent me from moving trailer to troubleshoot.
I’ve owned 5 brake controllers. This is the only one I’ve disliked. This controller has non digital controls (should have been my first clue it might not be good) it just has two slide controls. Problem is two things, the slide controls themselves are black, the same color as the case on the unit and you can’t even see the position of the slide controls because they blend in with the color of the case. It’s impossible to tell if they’re turned down all the way, turned up all the way, in the middle? The other problem is that the slides are so imprecise, They slide way too easily and there’s no detents and I found if you even bump the unit slightly or are going over rough roads the slide switches migrate. I was towing a couple of weeks ago and I thought I had the switches dialed in as good as I could, I was on some rough roads, due to road construction in the area, the output switch vibrated over to maximum and the next time I hit the brakes , the trailer locked up completely. So I had to turn it off until I could get to the next town where there was a parking lot I could readjust. I’m definitely getting rid of this thing and I definitely recommend you do not buy it. Buy something with digital output controls so you know precisely where the settings are. I firmly believe this controller is dangerous and I know if I keep using it I’m going to get an accident.
Custom cable made my brake controller installation a simple project. Fit perfectly and took all stress out of the job. I would buy again without hesitation.

Yup, still working as supposed to. No complaints. Well worth the money.
This wiring adapter fit perfect between the Curt Adventurer brake controller and the pigtail harness in my '06 Tundra. Remove the truck's driver side kick panel, cut the truck connector loose from where it was secured, and plug this adapter into both the truck and the brake controller. Plug and play.
Mating harness is perfect. Well made, quality connectors, proper length, time saver, priced right, a no brainer. Buy it!!!!!

Great. This controller is very consistent in applying dependable braking while towing our travel trailer. After dozens of trips and thousands of miles the unit continues to do the job. Very satisfied.
Item worked great. It was able to connect with the Trailer Brake Controller and straight to my wiring harness in my truck. I couldn't have asked for a better installation! Thanks etrailer.com!!!
This was my fourth order from etrailer and, as were the earlier ones, was delivered quickly. The instructions were clear and easy to follow and it took me only about 15 minutes to install the Curt Venturer Trailer Brake Controller with the wiring adapter for my 2012 Tundra. The white ground wire did not have to be grounded separately as it connects to a white ground wire in the adapter. I used Velcro on top of the controller and beneath the panel instead of the included bracket and can easily make adjustments without removing it. Adjusting the slides on top and the left side of the controller to get the desired braking action and a test drive to verify took another ten minutes. Great product.
I was sent the incorrect "direct plug in" harness originally but after contacting etrailer they sent out the correct one. Everything works perfectly now.
The small rubber pieces that hold the brake controller to the mounting bracket instantly fell off and rolled away, not the best design. Other than that it is small and compact and works great!
Excellent controller for my needs...fast shipping and a great price too! I read up on Progressive vs. Time Delay controllers; and for my needs I felt this Curt controller would be just fine. I just finished installing and adjusting the controller this morning.
We recently bought a '99 Coleman Westlake Pop-up that weighs about 2,400 lbs. dry (much less than my brake-less boat trailer) and wanted to take advantage of the brakes that came on the camper for when we travel in the SC & NC mountains camping. On level ground I have found the controller to be very responsive and easy to adjust. I am sure having working brakes in the mountains will be nice! As others have said, finding just the right place to mount the controller was the most difficult part. The "plug & play" adapter/harness was more than long enough to complete the installation. Oh, did I mention fast shipping too! I am another very satisfied etrailer.com Customer!
Haven't installed yet since I do not have a level surface to calibrate the Curt 51140 brake controller. Travel Trailer currently resting on Jack Stands while in process of doing some restoration work.
Delivery was as expected. Ordered on Sunday and received on Thursday.
I have downloaded and printed PDF instructions (Printed in "Fit to page" for larger print) that will be added to my Owners Manual.
Regarding price; I looked a several RV parts shops and Auto Parts stores both on line and walk-in stores. eTrailer had the best price and the accessories I needed for the installations. The free shipping for orders over $99.00 helped make my decision to place my order. I will revisit the review page when I have everything installed and working.
Thanks eTrailer,
Gerard
Great website, easy order, arrived a day ahead of schedule. I recommend this site .
I was in need of a trailer brake controller along with the wiring harness. ETrailer had a unit in their inventory and made an exact match to connect to my truck. It was delivered on Friday and I pulled a 30 foot, 7500 pound trailer 170 miles on Saturday with brakes that worked flawlessly. I couldn't be happier with my purchase.
The adapter cable I ordered worked just as advertised. It took me longer to find the plug in the pickup than it did to hook the whole thing up. I was transferring my Curt Reflex from my Honda Ridgeline to my new Toyota Tundra. Everything hooked up and works perfectly. Shipping was excellent this time. I'm still waiting for delivery on another product from a different supplier...only 6 days late. Your web site offers some nice products, so I'm sure I'll be ordering again soon. Excellent service and I'm well satisfied. Thank you.
I have a 2012 Toyota Tundra and I was adding a trailer brake. This adapter made it simple, took only minutes to install and no cutting wires.
