If your vehicle already has a 4-way flat, this kit includes everything you need to install an electric trailer brake controller and 7-way connector. If there's not an existing 4-way flat on your vehicle, you can purchase one separately.I purchased the brake controller and wiring harness from you all and installed it watching the video on your website. I followed the instructions to an absolute T. Got everything ready and tested the product and got an SH error code for the blue brake wire shorting out. I pinned and measured resistance and everything was coming back fine (4+ ohms resistance). I then hooked a power prope to it to find the short along the frame and nothing. I had power from the female connector all the way up to the brake controller. After 4 hours of troubleshooting, I found that the female trailer connector was shorted internally. See the attached picture. The blue and green ring terminals inside of the female trailer connector were touching. Replaced the trailer connector and now all is well.
Kate M. my salesperson, had a most professional interaction with me being certain of my and my vehicle's needs. In addition, she walked me through the complete installation process. This I completed, wiring the 7-way and the Curt Discovery Controller making no errors along the way. On the first test, every terminal on the 7-way tested as it should. When we came home with the RV from the dealer, all the lights and the brakes worked flawlessly. Many thanks!!
Another successful order and install from etrailer.com! Always fast shipping and excellent installation guide videos! Installed on 2021 JL Wrangler EcoDiesel.
Very easy to install! I put off installing this stealth hitch for a month dreading taking off the body panel... Just to find out it was extremely easy. The whole process took me four hours, would have been done sooner if I didn't unnecessarily take off a small battery cable that prevent the car from starting. The part of the makes me happy is the added safety from the superior strength in steel and the protruding ball to help protect from getting rear ended!
Installation instructions are adequate, provided you keep the wires straight. After final install everything worked fine. The online video was a little too simplistic, and skipped frustration in finding where to put things. Final outcome was a clean install. It would have been nice to have been offered the dashboard knockout piece for the Highlander. I drilled mine out and it works
Have a 2021 Durango SXT. Bought the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires, Tekonsha POD Trailer Brake Controller - 1 to 2 Axles - Time Delayed, and Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite Brake Controller 12" Long. 7 wire was easy to install but break controller a little harder do to the vehicle I have. Previously bought tow hitch and 4 way wire trailer plug from etrailer. Very happy with all.
One year review - Exactly what we needed to go along with the Tekonsha Prodigy P2 Trailer Brake Controller (etrailer item# 90885) and a Class V hitch on a 2008 Toyota Tundra pulling a 1999 WW (WW Trailer Manufacturing) 2 axle horse trailer. We initially also ordered the Tekonsha brake control adapter for Toyota, but it did not work for our particular application, so the installer went a different direction.
I have a 2018 BMW X2 that did not come with a factory tow package. I had an etrailer hitch and 4 way plug installed last year and has been perfect since. I just recently purchased a camper and needed to have a Brake controller & Brake controller 7 way deluxe kit installed. My mechanic installed them with the detailed instructions that the units came with without any issues. The Tekonsha P3 is extremely user friendly and is working flawlessly. A bit overkill for my car being I can only tow max 3500 pounds, and my camper is 1 axel. this unit is rated up to 3 axles. I look at it like this way, when I trade in my BMW I will take my P3 with me. etrailer is amazing with the support & products they provide and I highly recommend them to anyone who asks me.

My Meghan said this was very easy to install, works great no complaints whatsoever.
It fits and works though required a modification, I think mine might have just been a bad part out the factory.
The install wasn't too bad but I spent way too long trying to figure out why my left turn signal was showing as tail lights and my tail lights were showing as my left turn signal. Turns out the wiring was wrong on the 4 pole connector (picture attached). I wasn't sure which end was wrong (the 4-pole adapter, or this adapter) so I cut and swapped two of the wires on the 4 pole adapter to make it work correctly. Definitely an issue with the manufacturing process, but the dealership wanted $2,700 to add a receiver and 7 way. Buying all the parts (and a new brake controller) from here was only around $700.
For anyone curious about this model Jeep. The main battery is under the drivers seat, it makes this install super easy because you don't have to bring anything through the firewall. I brought my wires through the small vent behind the plastic rear-quarter panel (big piece of plastic that wraps around the back) on the drivers side, then just under the carpet up to the battery. Once there I removed the rest of the grey layer from the wires, cut the black wire, and continued with the white wire and rest of the black wire to under the dash (for brake controller power and to send the signal all the way to the back).
The Universal installation kit #ETBC7 arrived with the Tekonsha Prodigy P2 brake controller. Everything is in great condition and is exactly what I needed. The installation instructions are straight forward and easy to understand. I can't wait to get everything installed so I can get my trailer on the road. I'll give an update after it's installed.
Worked perfect and looks great. The 7 way plugged into the existing 4 way. That left the White(ground), black(hot), yellow(reverse) and blue (brake controller). With my Nissan Pathfinder,I only had to connect the white and black wires and this 7 way pin was setup.
Easy to follow instructions and well made materials. Only plus would be heat shrink connectors but no one else provides those either. As a diesel mechanic I can say this is a quality kit.
Very nice item, very easy to install all the connectors were good quality and precrimped on the wire ends, the only thing the little plastic tab that locks the plug into the receptacle snapped off quite easily now I have to wire tie it to secure it but other than that very nice product includes everything you need for a nice clean install.
Easy install (I did not wire in the hot wire for the inside brake controller). I am using a Bluetooth brake controller that is working very well for my needs.
Install went fine and all but after a single winter and less than 6 months - the internals oxidized and rusted out completely, a few pins broke. I blame poor design and weak materials, see pictures. Not sure what do to about it at this point, total junk.

I know that weather and road debris can take a toll on harnesses however I am surprised that it did in a short time. To help with longevity you can use dielectric grease, such as part # 11755, on the pins when making the connection to the trailer. Keep on eye on the bracket and use a rust resistant spray paint like Rustolem to touch it up. Some with use wire loom like part # 7509-1 to wrap around the wires to help better protect them. I will have our Customer Service team reach out to you.
My truck didn't need extra wire, they sent the wrong mounting bracket for the plug, and the bolts beban to rust within a few weeks. They should use stainless.
I've had this trailer hitch on my 2013 Outback for a year now and love it! I tow a popup tent trailer and this hitch works excellently. It was a solid half day installation but my Dad and I were able to knock it out no problem! I love the discreet look of this since I'm not often towing the trailer. I couldn't recommend enough! Way better than the bulkier, less tasteful versions available.
1 year review. I installed this product on my 2017 Toyota Highlander. As a person inexperienced with vehicle electrical systems, I found the installation challenging but achievable. I appreciated the advice and videos from etrailer.com. I liked the final fit and finish on my vehicle when using manufacturer hitch and bumper kit.
After 1 year of usage, I have found 4 specific opportunities for improvement.
1. Water accumulation in the plug cover flap. After rain, I flip the flap up and water spills out of the crevice in the flap. There is also a small amount of water in the plug itself, but unclear if there is rain entering the socket or if this is from spillage when the flap is opened. This needs to be sealed to protect the plug!
2. Poor quality top mounting nuts and bolts. I overtightened one of the top bolts and it sheered off. I replaced it with zinc plated hardware. In my picture you can see after 1 year of use the included bolt on the left is corroded and the hardware store bolt looks new.
3. Poor quality front mounting screws. You can see the 4 rusting screws in the picture. These are designed to be exposed to weather, so I was surprised to find rust forming after the first few weeks.
4. Poor quality attachment point for the flat connector. The 4 way slips onto the side of the 7 way mount and is held on by rubber friction. It never stays in place and is always dangling.
One other suggestion is to offer a kit made for the newer wireless brake controllers. It could have less wire, fewer connectors, and cost less.
Because of the above problems I will have to replace the 7 way plug soon. Therefore I gave the product only 2 stars and would not recommend purchasing it.
I installed the kit on my 2007 Toyota FJ Cruiser, which was already equipped with the factory 4 wire connector, and it was pretty straight forward. Of course, it's universal kit so there are lots of variables between vehicles, bur that being said, it fit mine just fine. The only thing I did differently is tapped the brake light circuit at the master cylinder with the included Scotch Lock rather than at the brake pedal since my vehicle has a manual transmission and the clutch pedal made it all but impossible to access the circuit there. Overall, the hardware seems to be of good quality and the instructions were fairly easy to follow. I must say the included 4-wire connector extension isn't very secure in the connector bracket, but a little RTV should fix that. I will be towing a lightweight A-frame trailer and I'm sure this is just what I need.
Works great as a controller, doesn't take any room under the dash. I was advised to unplug it and put it in the car or trailer because it would be easily stolen. Wireless may be my only option because I have it on a hybrid.
Everything I needed was in the kit. I now have full trailer lights, brakes and electric controls on our 2022 Toyota Sienna Hybrid AWD. Thanks for the good advice, videos and quick delivery!
Complete wiring kit and is of very good quality. I replaced the connectors that came with the kit to a heat shrink style to prevent connection problems in the future. Kit would have been 5 stars with these included.
This is exactly what I needed to install the Tekonsha P3 controller in my 2000 Silverado. The 25' wire was installed from the engine bay to the trailer connector per the included instructions. It's been working perfect for over a year now.
Install was done very well, and the brake controller works great
Someone took great detail planning for this installation package for the complete installation of the trailer brake kit. Every zip tie and screw was included with detail and definition.
