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.

Simple to install kit that does exactly as listed. Very thorough instruction that were easy to follow.
It does what it says on the tin. Easily lit up my XJ so I could tow it. Only regret is that by making the connections at the rear, you don’t get the front market lights on the toad. I should have connected the running lights diode in the harness under the dash so all the marker lights come on at night.
I’m always extremely satisfied with Roadmaster products. I had just bought a new truck and planned on towing it so I needed everything to get it ready to tow. This review also applies to to the other items I purchased.
I thought I order the 7 to 6 pin wiring harness for my vehicle as I have the 7/6 cord I used when I pulled my pickup. I also ordered the 6 pin mounting bracket with the 6 pin adapter that wires into the harness. I received the kit which is a flat 4 pin harness.
etrailer is a great company for towing products. They have fast delivery and they have nice installation videos. This order I added 2 more diodes to wire my 2015 Subaru Forester to have separate wiring for break, running, and turn signal lights.
First of all Justin B,was awesome so very helpful and knowledgeable went over everything with me and then double checked what was needed before I placed the order for my 2022 maverick to be flat towed, order only took 3days to get to Fl.Kudos to Justin B all the guys putting together the order
and etrailer awesome job,will definitely use them again for any of my needs.
Works perfectly and straightforward instructions made it easy to install.
This system worked perfectly from experience. They help from trailers e trailer agents was crucial for guiding me through the process.
It is exactly as advertised, not yet installed but looks pretty self explanatory
THE EQUIPMENT IS FINE. THE INSTALLATION VIDEOS ARE SUPERB. MAKING PURCHASING THIS PRODUCT VERY WORTHWHILE.
the service was great, they went out of their way to make sure they were providing me with the correct part
I have order several things from etrailer. Their products are great. Due to nobody's fault but my own I ordered some wrong things. The return was so easy, no questions asked. I would recommend this company to anybody.
I’ve used several of these and they always work great.
etrailer videos are a great help!
Excellent help when ordering and follow through when order received. Can’t beat their customer service and sit!!
Installation instructions were great, no issues or questions. I ran the wire thru the frame, and used split wire loom and tape to protect wiring when outside the tube frame.
Items arrived right on schedule and in good order. I ordered three items in the last few weeks. Their CHAT agents were extremely helpful in answering all my questions about compatibility with my vehicle.
My parts arrived intact and in a timely manner. I am very pleased with my purchase.
Great tow plate , easy to install
Good instructions and easy to install.
Fits and works just as it should.
Product is very well built and is hidden within the bumper/grille. Installation wasn't too difficult, reinstallation of front bumper requires 2 people.
Pleased with end results.
Lori was spot on in making sure I got the correct base plate assembly and light package for my 2015 Jeep Wrangler Sport. Deliver was within the projected timeframe and installation when as per detailed instructions . Good job Team ETrailer, that is why I keep coming back
We tow a 2022 Ford Escape behind our Winnebago motorhome. This wiring kit did the job for us. Everything working great!
I used this on a 1988 Toyota Land Cruiser, so I could flat tow it behind an Motorhome. Easy to install!
The install was more challenging than the tow bar itself but we got it done. Be patient with the tail light diodes they are tricky to fit but not impossible. I ended up using some 3m double sided adhesive sticky’s to hold the diodes in place while i pushed the tail light assembly back into position.

Diodes were not the ones I needed even though the etrailer site said they were. I had to purchase the correct ones from the auto electric shop where I had the wiring done.
