This complete kit includes everything you need to connect your RV's tail, brake, and turn signal lights to your towed car. Diodes prevent feedback and wire your car to operate as a combined system. Includes a 7-way to 6-way straight adapter cord.

Specs:
Note: For applications that have separate lighting, this kit will cause your brake lights to function as both brake and turn signal lights. A wiring converter (118158 - sold separately) and 2 additional diodes will be needed if you want to retain separate turn and brake signals.
Separate vs. Combined Lighting Systems
Some automobiles operate on a 3-wire system, wherein the brake signal and the turn signals travel along different wires to illuminate different lights. (Typically, these vehicles have amber turn signals.) This is referred to as a "separate lighting system". When you hook up for flat towing using this kit, your towed car's lighting system will operate in a combined fashion regardless of whether it typically has combined or separate lighting. This means that the brake and turn signals sent by your RV to your towed car will be carried on a single wire. As a result, your car's brake lights will do the flashing for the turn signals. Your vehicle will still function as designed when not hooked up to your RV.
Do You Need a Brake Light Relay?
Because this kit wires your vehicle as a combined system, a brake light relay (RM-88400 - sold separately) may be required if you use a supplemental braking system with your towing setup. A supplemental braking system depresses the brake pedal in your towed car every time you apply the brakes in your RV. So, if your towed car's brake lights illuminate when the brake pedal is pressed and the engine is off - as is the case when towing - then you need to install a relay to ensure that the lights on your towed car always act in accordance with the signals sent by your RV via the wiring harness. Without a relay, the brake signal from your towed car will override the turn signal sent by your RV when you slow down to make turns, creating a potential hazard.

One thing bit us in the butt, forcing us to cancel a trip at the last minute (when testing that our towed vehicle's turn signals, brake lights and supplemental brake system was working before driving off!): the left-turn signal prong in the male part of the connector (that plugs into the towed vehicle) was not opened enough, so no steady connection was being made because there was no contact between the prong and the walls of the female part. This had worked in a previous test. Picture included. Make sure to use a flathead screwdriver to open each prong up so full contact is made!
Over-all, the Roadmaster products were great! I watched all videos for install several times. I went through the Jeep frame-rail front-to-back. But I did not loop the wire kit up unto the engine compartment just to cut and splice for the supplemental brake system. I called etrailer and asked whether there was an issue bringing the supplemental wiring directly to 6-wire plug which seemed to be a new concept with no answer either way. This actually worked well and ended up as a cleaner install with fewer cuts/splices
Very straight forward install, easy to follow instructions. If you do this your self be prepared, the factory light wiring isn't very long or thick it was difficult to strip the wire back far enough to double it over to get a good connection. Upon completion of the wiring, I double checked all power at both plugs, it was all good, I installed the lights, brake and turnsignals worked great, I didn't have any running lights. About 3 min later they came on and stayed on. I don't believe this has any thing to do with the kit, this vehicle has all kinds of light sensors, darkness sensors, rain sensors.. etc. I believe it just too a min or 2 for the lights to actually come on.
I chose the order by phone option. The website is well organized, but, I had gone too long without hearing another person. I have received several orders from etrailer after purchasing an RV last summer. I knew we would be Purchasing a Toad. I don’t have any experience with towing another vehicle, so I had plenty of help in finding the right equipment for me. The delivery times were all easily tracked and arrived in good condition. As md on time. I had the simple tools required to install the base plate and hitch. The videos available on their site are clear and easy to understand. I have had a great overall experience with etrailer.
I haven’t had time to install this product yet, but I know it’s going to work exactly as the customer service is always superior to get the right parts sent.

I had a Toyota Tacoma that has separate blinker lights. Took a mechanic that was knowledgeable in electrical wiring. Followed the instructions and it worked perfect. Used it several times since
Works as designed but wish i would have got the curly cord vs the straight cord between my Entegra and jeep
Jenny N - 04/02/2022Knowledgeable people. On time delivery. Great products.
Products arrived earlier than was expecting. Haven't had a chance to install just yet, but I am looking forward to that process. etrailer has been very easy to work with and very knowledgeable about the different products that are available for my project.
Had it installed by my RV Service guy, and it’s worked great for us in towing our Jeep Cherokee with the Roadmaster Falcon 2 towing system!
The kit contained all I needed and their on line video for installation in a 2015 Kia Soul was excellent. Hardest part was routing the wires to the back of the car, but overall it was much easier that I thought
Very good quality, video and instructions very informative. But, I still cannot figure out where to mount the six pin bracket. Also, no self tapping screws…
Jenny N - 10/29/2021Great service. Knowledgeable people to help you get the right product's. This is my second opportunity to use this company. It was great both times. I wish more online companies were this great to do business with.

Great customer service!
I am very happy with the Roadmaster wiring kit. I was worried about cutting into the taillight wiring on our 2017 Grand Cherokee but the directions were very clear and worked just as advertised. It has been a good year traveling in our coach to 11 states towing our Jeep. A lot more RVs on the road, hope they make more campgrounds to accommodate the increase. etrailer is the best !
