This wiring kit carries brake and turn signals from your motorhome to your towed car while you're flat towing. Diodes protect your car from damage from electrical feedback.
Features:
Notes:
"Don't be intimidated by diodes: if you can strip and crimp wire, this installation will be no problem."
A combined lighting system, or 2-wire system, uses the same light bulb to signal both braking and turning. (In other words, the car signals a turn by flashing the brake light.)
A separate lighting system, or 3-wire system, has the brake signal and the turn signal light up independently of each other. Typically, the turn signal is amber.
To keep the separate lighting system on your car functioning properly while you're flat towing, add a wiring converter (118158 - sold separately) and 2 additional diodes.
If the engine is off and your car's brake lights illuminate when you press the brake pedal, you need to install a brake light relay (RM-88400 - sold separately) with this kit. Without a relay, your car's brake signal will override the turn signal sent by the RV when you are slowing down to make a turn, creating a potentially dangerous situation. Other drivers will see that you're slowing down, but not that you're making a turn. With a brake light relay, you can signal both and travel safely.

Took a bit to get to the rear lights on the wrx - trim pieces etc. But once there the instructions were easy to follow and the lights work great!
I returned this item in favor of the Curt Bronco flat tow light kit. The Curt kit is far superior to the Blue Ox kit. The Curt kit is totally plug and play no diodes to deal with. I would have bought the Curt kit from you if you sold it. You would be better served with the Curt kit.
Perfect for my application on a 2001 GMC Sierra 1500 HD.
Installed on new Ford Maverick Hybrid pickup. So far so good. Survived 8000 mile West coast trip with no problems.
easy install. I had to use my red connectors because I didn't want the blue ones getting a loose connection with the small gauge wire.
Had everything I needed to wire my Jeep Grand Cherokee. YouTube videos exist to help. There some surprisingly difficult places to route the wires along the frame.
I have inventory all packages and everything is here a ready for installation. All parts are quality and instructions are very clear.
eTrailer was very helpful in choosing the correct hitch for our rv and car. They also provided a special brake application in the car that makes it super easy for toad braking.
I am 72, and I hook up this toad and pull it with confidence. The instructions to hook up the toad was presented with ease. They knew exactly what they were doing, and we didn't rush through the demonstration. I would recommend eTrailer to anyone.
Great quality product and I like that they supply the few extra feet of brown & green wire to go between tail lights. The other brand I bought from you did not and I had to go to a big box store to buy another roll of trailer wire to complete the installation on my last vehicle.
We love the Blue Ox kit! Pretty simple to use.

Performing as intended. Good quality.
Perfect!!!
The Blue Ox Tow Bar Wiring Kit - 4 Diodes work exactly as advertised. The diodes work to separate the harness from the system, so there is no back feed to the car's electrical system when the brakes, lights, or turn signals are activated in the motorhome. The car's rear lights are activated in sync with the motorhome lights. So much easier to hook up the "toad" to the motorhome using this harness.
Installation when very easy, after I figured out how to access the taillights on the 2019 Chevy Traverse, but now that's another story.
I would highly recommend this harness.

its still a great product even after a year and I am sure it will last many more years
Dealing with etrailer for several years, always fair price, prompt service & communication regarding orders. Also Excellent videos that are extremely valuable.
Bety easy to install if you take your t ime
Toughest part of installing this system was determining the best and neatest way to route the wires from front of the vehicle to the rear. Works great but does not provide wiring to run the third/middle brake light on the towed vehicle which in my case is a 2010 Chevy HHR. I subsequently opted to install a system which constantly charges the HHR battery from the RV power which allows me to keep the HHR power on so when the Brake-Buddy applies the brakes all the brake lights illuminate. Otherwise a perfectly good system with everything you need for an easy install.
It makes wire easy
Went well except for instructions installing baseplate for my 2017 Silverado. After grille removal was not close to the instructions. I [looked for installation videos for] 2018 model and instructions for grill and bumper removal was right. Nice project and saved a lot on install. etrailer is great at putting together the equipment you need. Love website to research products. Have not pulled truck any where yet. [(Covid)]
Customer Service is excellent! The tow bar was delivered promptly and should work great. I didn't receive the wiring kit I ordered but when the company was contacted....they were great to work with and shipped another right away!!
Everything needed to provide motorhome lighting to the towed vehicle. This will NOT eliminate towed vehicle battery drain on long tows, and while many have a way to boost towed vehicle battery during tows, no one seems to have the reason for the battery drain. I thought the diodes would eliminate that problem.
The order arrived very quickly and is all intact. The (base plate) picture quality is a little poor from Blue Ox, but I talked to Angela B. and she is emailing the instructions to me for better viewing.
I might add that Blue Ox would have charged for shipping.
Now it is time for the installation.
I was looking for a product that had everything I would need to do the job without having to go to local auto parts store to find special parts not usually stocked. The instructions were pretty good but could have been better with a couple of photos and details in the routing near the engine compartment and wire loom for added protection in the area. The finished look is well hidden as it should be and not hard to install.
Still using magnetic lights. Haven't installed wiring kit yet.
Just what I need to do a proper installation.

Works great. Just what I needed!
I am new to the world of towing a vehicle behind an RV and found a lot of articles/videos on the interweb, not having a clue what to expect except what I've read and watched on the web I reached out to etrailer.com and Courtney B answered all my questions, removed all my doubts of what i was doing and provided everything we needed in the timeframe we needed it at a reasonable price! I can't thank her or etrailer enough!!! I will buy here again and trust in they're how to videos without question. Thank you
