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.

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!

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.

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 :)

I want to thank everybody from etrailer.com very good communications. The D ring bumper mount and the roadmaster diode 7 wire to 6 wire wiring harness they said it would take 4 to 6 weeks for it to come in and It only took two weeks.

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 ran out of time to install this myself, so I had it done by a trusted Auto repair shop. While they had not done this specific kit before, they did comment that it was more complex than they had expected. They also installed the base plate and breakaway switch for the supplemental break and took about 10 hours in a fully equipped auto shop. The estimate the next one will take about 5 hours and only charged for that. This leads to a couple of points. 1. If you choose to do this in your typical home garage, plan on a day or two. 2. Once installed properly, it is a really slick system.

Excellent product. Fast delivery as usual.

Easy to follow instructions! Installed on a 2011 Mini Cooper S hatchback. Hardest part was figuring out what wires went to what bulb on the Mini. Once I got that squared away, install was a snap! I did mount the 6 round plug socket to the Mini's front license plate bracket. Not a great spot. May switch location or go with a 7 round to flat 5 coiled wire.

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.

Hi Robert, Thanks for your feedback! I reached out to my contact at Roadmaster and this is the solution he provided: Check the wires at the taillights and make sure that they are on the correct wire. I have the colors for the taillights and brake lights. Taillights would be a Grey wire and the brake lights should be an orange wire. He should install the Diodes in between any plug and the light its self. Sometimes when you tap into after the plug, the plug feeds back into the cartruck.

Running this wiring on my Wrangler 4 door is a bit of work, aside from that the wire/plug setup has gone 20 thousand miles now and no issues, works well. I am also running the trickle charger through this connector/cable a separate item just wanted to mention it is easy enough to use with this. On a side note, on my RV i had to fix the plug wiring, they had it wrong from factory. So if you get funny light behavior after hooking this up, check your vehicle wiring for accuracy, especially on RV's it is all hand done and mistakes happen.

Works as it should wires could be 3’ longer. Had to do a re-route going to rear of vehicle. 2019 Buick Envision. I used this with a Demco Stay in Play Duo. Very happy with etrailer videos and customer support folks. Had to call several times during install of baseplate, braking system and taillight kits. The auxiliary brake switch is a real bear to put in. As in recline seat all the way back lay upside down and try to see the correct bolt. There were a few working words spoken that day. Once installed and setup the systems works flawlessly. The videos are just awesome. Would have gave it 5 stars if I didn’t have to do wire re route. (I used the path in video)
