Roadmaster Tow Bar Wiring - RM-15267
- Diode Kit
- Splices into Vehicle Wiring
- Universal
- Tail Light Mount
- Roadmaster
Diode kit allows you to use your vehicle's tail lights and wiring system while preventing feedback from your RV. Wires 2-wire and 3-wire systems to operate as a combined lighting systems. Includes 7-wire to 6-wire Flexo-Coil electrical cord.
Features:
- Lets you wire your vehicle to accept your RV's tail, brake, and turn signal lights for flat towing
- Wires towed car as combined system so that brake and turn signals travel along same wire
- Prevents electrical feedback and the damage it can cause to your vehicle's electrical components
- Diodes powder coated aluminum case is corrosion resistant and provides protection from the elements
- Brake light relay (RM-88400 - sold separately) may be required if used with supplemental braking system
- Flexo-Coil cord is resitant to water, oil, chemicals, and has silicone-injected plugs to prevent corrosion
- Center pin on 6-Way plug wired to 12V power, there are two industry standards
- Includes:
- 4 Hy-Power diodes - 27' long
- 4-Wire harness
- Wire connectors
- Cable ties
- 1 Ring terminal
- 3' Long plastic loom
- 8' Coiled cord
- Vehicle mounting bracket
- Socket
- Made in the USA
- Limited Lifetime Warranty
Specs:
- Diode Max amperage: 85 amps
- Diode Max voltage: 24 volts
- Coiled cord max length: 8'
- Coiled cord retracted length: 15"
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 (RM-792) 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.

The wiring kit was perfect and everything you need is there. I would have rated it a five, except that the multi-colored length of wire that comes with the kit was just barely--and I mean just barely--long enough for my application. If I had cut the ends even a quarter-of-an-inch shorter I would not have had enough wire to complete the job without splicing additional wire in. My only complaint is that the length of wire that comes in the kit is for small or short cars only. This is the second wiring kit that I bought. The first one was a coupe of years ago and was for a Ford F-150 pickup. In that application the wire was not long enough to run from the front of the pickup to the rear and I had to splice extra wire in to make it work. As long as you know that up front, then the rest of the wiring kit works great and the directions are very good.
Comments
No problems after one year. The contact points are not corroded and everything works great.

The wiring kit was mostly OK. They claimed the wiring supplied was 27' long, however, what I received wasn't even 20' long. I had to made a splice on all wiring leads near the front of the bumper. The diodes and rest of the kit worked as described. Upon testing, there were no issues when hooked up to my rig. I also added the brake light relay and wired it through the supplied harness as well.
Comments
I reached out to Roadmaster and they confirmed the wiring with the kit is 27 inches.

The wiring kit was installed on a 2020 Jeep JL Sport S. I really appreciate the ordering process and quick shipping of etrailer. The Roadmaster 7-6 wire cable is heavy duty and the coiled design keeps it from dragging on the ground. On the etrailer website there is there is a Q&A segment that has a flowchart to see if you need a brake light relay kit. It states that if you get a brake light with the ignition off you need the kit. I finally learned that the Jeep JL goes to sleep about 5 minutes after the ignition is turned off- so you do not have to use a brake light kit on the Jeep JL.
Comments
We pulled the Jeep several times this year. Installing and removing the cabling was quick and easy. The wiring kit worked well with the brake lights and turn signals working like they should. Installation was made easier after watching the videos

We have towed our Jeep almost 2,000 miles since installing the recommended parts from etrailer and it has worked perfectly on every connect and disconnect along the way. Tows beautifully, even at 70 mph. Excellent customer service and helpful videos from these folks. Would recommend to anyone needing help with parts and guidance in towing their toad to give them a call.
Comments
Our system is still working perfectly a year later. Our Jeep is a 2018 Cherokee Trailhawk and while we’ve seen some RV forums talk about “death wobble”, we have never experienced this using these Roadmaster products towbar & baseplate. We tow the Jeep with our 39’ Class A gasser and hardly know its back there. Even on sharp corners the Jeep follows perfectly and no binding. Connecting or disconnecting takes maybe 5 – 7 minutes. Then check all of our lights, make sure the Jeep is in neutral wbrakes off and we’re on our way. The braking system that we installed purchased from etrailer is the “Stay-n-Play Duo”. I would recommend that to anyone looking for easy operation. The installation time was a bit lengthy and involved but once completed makes all of your towing trips much easier. Just the flip of a switch and the braking system is ready for towing. No portable unit to lug around and adjust each time you tow your vehicle. The etrailer folks made the perfect recommendations for our needs and everything has worked GREAT!

My project on 2021 Ford Ranger includes the tow bar, base plates, wiring harness, supplemental brake system with break- away switch and rv brake warning and brake relay. Every component is the highest quality, fit perfectly and works exactly as it should. The written instructions were very good for this complex assembly but the saving grace was all the excellent instructional videos detailing the work. One of the box’s damaged in shipping was missing parts that were quickly replaced in just a few days. Great products and great support.

As a product development engineer, i know the challenges in designing aftermarket products that perform to expectations and are competitively priced. The five Roadmaster products that I’ve purchased and installed have been very well thought out, manufactured without defects, fit with OEM chassis has been excellent, packed and shipped without damage to the items and priced reasonably. Specifically, these items are a Falcon 2 tow bar, base plates for a 2017 Fiat 500 and a 2021 Jeep Rubicon, and their associated brake & stop light wiring kits.

This was easy to install and it works very well. I installed it on a Ford 2021 F250 pick up. The pick up does have the separate brake and turn signals, so you need to wire it as such. I would recommend this kit.

2018 Jeep JL Wrangler Unlimited
Received my kit and everything I needed was in the box. I did all things according to the excellent video that I watched numerous times. It paid off, because installation was a breeze. It took me about 21/2 hours from start to finish, 1/12 hours to run the wire through various places in order to keep it away from any moving parts beneath the under carriage and partially through the frame. Hooked up the passenger rear taillight first. Brown wire running from passenger side was a little short so I took an old piece of spare wire and spliced it into the brown wire. I used a shrink wrap making sure I had a good solid connection.it was very easy and something I thought I could never accomplish, but it turned out very well. The man in the video and how he walked you through the whole process, I felt it was doable. Thanks to good instructors and step by step videos, this install was very easy. Thanks etrailer for another good lesson and product. Thanks-John

Still working like it did when it was first installed. One of the best investment I ever made for towing my jeep behind my motor home, and knowing my lights on my jeep are working and making other drivers aware of my stopping and turning. Thanks etrailer for a good product.

Good wiring kit EXCEPT THE FOUR WIRES RUNNING THE LENGTH OF THE VEHICLE ARE TOO SHORT! This is even mentioned in your video for a Honda CR V!!! The CR V is one of most common toads out there. Why hasn’t this been remedied? I had to spend an additional $xx. Plus the time to get more wire. Would have gotten 5stars except for this issue. I’ve installed several of these kits on other shorter vehicles without issue.

2016 Jeep Wrangler
Towbar wiring system arrived within 4 days of placing my order. This 7 to 6 wire system is an upgrade to the simpler 4 wire plugs I've used in the past and will allow me to add on a battery charge line or brake system later on. The demonstration video was indispensable in hooking up the wiring and diodes. Though running and connecting the wiring does take longer than a 10 minute video. Now I can tow my 2016 Jeep Wrangler behind my RV.

When unhitched, the arms do not stay locked in. They keep sliding out. The connecting wire plug has become so hard to remove I bust my hand every time I disconnect it, which is taking longer every time. I am at the point of wondering if there will be a time I won’t be able to disconnect the plug. It was also installed onto a flimsy plastic piece on the front bumper of the Jeep , which means I have to hold the plastic piece as I use counter pressure to pull the plug with one hand, so the plastic does not bust.

I ordered this kit to get me a heavy duty coiled cable with room to use one input as a dedicated power supply from the bus to then be sent to the towed battery to keep it charged going down the road. the diodes i chose not to use, as i have a hopkins plug and play kit on the way, that will marry up the 6 pin fitting I just needed the cable with the 7 to 6 adapters, it was the best price for the need :)

Thank you for leaving a review! It sounds like you need a brake light relay, part # RM-88400
Roadmaster Brake-Lite Relay Kit for Towed Vehicles
$32.86. In this situation, it sounds like what is happening is your vehicles brake light is overriding the turn signal of your towing vehicle. As a result, when the turn signal is on and the brakes are being applied, the cars behind you only see that you are slowing down and not that you are about to make a turn or switch lanes. What this brake light relay does is make the signal from the towing vehicle the one that is displayed on your towed vehicle as well.
