1986 Dodge Ram Pickup - Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit

Diode kit allows you to use your Dodge Ram Pickup'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; 30' long, 4-wire harness; wire connectors; cable ties; 1 ring terminal; 3' long plastic loom, 8 ft coiled cord, vehicle mounting bracket, and socket
  • Made in the USA


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.

Video Transcript for Roadmaster Diode 7 to 6 Wire Coil Kit Installation - 2005 Dodge Ram Pickup

Today on our 2005 Dodge Ram 2500, we're going to be taking a look at and installing the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, Part Number RM-15267. Now that we have it installed, you can see this nice coiled 7-way to 6-way power cord. It's coiled to keep it up off the ground. It'll stretch out and come back as it needs you as you turn the corners with the vehicle and the tow coach. Now, we can go ahead and test our system. We can try our tail lights, our left turn and brake, and our right turn and brake. Now, with our Tow Doctor hooked up, we're not going to get both bulbs on the brakes to flash at the same time, but if you have a turn signal bulb, it's going to be that they share the brake bulbs, so if that one's working, your brake bulb's going to work also. Let's go ahead and show you how to install it.

Our first step is going to be to remove the tail lights from the vehicle. We're going to take them out and set them aside. We're going to take a T25, and we're going to loosen up the 2 screws. Once you have your 2 screws out on the other side, we're going to take a plastic panel tool so we don't scratch anything. I'm going to have to pop the light out.

There are 2 metal tabs that snap into the body here. Sometimes it can be a little difficult to get them out. You just have to work it out, and there's a little red lock tab on the light. We're going to push that out. This might require a screwdriver to pop it loose. Once you have it slid back, press in on that little tab and slide it off, and we'll set the light somewhere where it's going to be protected.

We'll do the same thing on the other side. Slide it out of the way, and we'll set that one aside. We're going to test for a signal for the parking lamp circuit. It's going to be this white wire. We're going to run some wire from this side of the truck over to the other side of the truck, so we can tie our lights together. We're going to snake some wire down through the hole here.

We're just going to need a green, a brown to go across. Now that we have our wires there, we'll take the wire that we tested that was the white with the gray tracer. We're going to cut that wire. We're going to strip it back about a 1/4 of an inch. We're going to put our spade connectors. Always be sure to tug on it make sure they're nice and secure. Now, we're going to install our diode. It's designed to stop your coach from backfeeding power into your truck system when it's being towed, so you're going to place the outside, plugs to plug. Then on one side, you're going to place the one that comes out of your harness on your truck to the inside. Then, the 2 wires that we ran from the other side, we're going to have a spade connector on that. We're going to do the same. Crimp both of these. Our marker lamp circuit is actually going to be the brown wire that's coming from the other side. We're going to plug that in to the other half of our diode, make sure it's secure. Our green wire is going to go to our turn signal and brake light circuit. Now, we'll test for those. This is the white with the green tracer. We can cut that wire, do the same thing. Now that we have our spade connectors in, we'll do the same thing. We'll put the outside towards the plug. This is our green. It's coming from the other side. I'm going to plug that in and the wire out of the factory harness. For ours, we're just going to take and peel off the 2-sided tape. We're going to stick them together. We're going to use some Loctite RTV, available on our website, Part Number LT37467. We're just going to smear a liberal amount around the outside. We want to make sure we can seal these up so no dirt and corrosion get in there. Once we have that, we can tape it all up with some electrical tape. We have it all taped up. We can go ahead and put our light back in. We'll just snap it on. They don't normally make a click sound on these. Just push them down, and if it's all the way down, the lock will go across. We'll just tuck everything back in the hole, line up our 2 tabs, snap them in, and we'll put in our 2 T25 screws. We're going to route our wire across. You can actually follow our factory harnesses. Now, we can just zip tie it across, just keep it attached to anything that the factory wiring harness and keeping it away from any kind of heat source or anything that could cause a chafe in your wires. Just be sure to keep it taut as you pull it across, so we don't have any slack playing down. Just want to be sure to trim back the excess on all your zip ties. Now, we're going to need to fish it up inside. Just take a little bit of tape and we'll attach it to that other cable. Now, we can pull our wiring up, we taped it on, and we'll put up all of our slack. The brown wires are tied together and they're going to the inside of the diode for the marker light circuit, and the other side is going to go to our harness to go to the front of the truck for the factory wiring, and then the output side is going to go to the plug. We did the same thing on the brake light side. The other wire went into input side and the green wire with the white tracer is the factory wire that went into the other inside of the diode, arrow pointing out is going to go into your plug. We're going to do the same thing on this side. We're going to silicone all the connections. We're going to tape them together, and then we're going to electrical tape everything to keep out all of the moisture and dirt. We're going to ground our lights. The white wire, we'll just take a self-tapping screw and we'll set it to the back here, and that'll ground our lighting. Now that we have everything connected up and taped, we're going to go ahead and heat up this heat shrink butt connector that we have here from Deka. That'll complete our install on this part of it, and I'm going to put our light back in. This inaudible 00:07:44 butt connected is the wire that jumps from the other side. We want to make sure we keep that from getting any corrosion or rust or water and dirt inside that connection also. That's why we use the heat shrink on there. Now, we can take our light, slip it back on, slide our lock over, line up our 2 tabs, snap it in. We can take our T25 torque screws, put those back in. Now, we'll go to the bottom side, and we're going to run our 4 flat wire all the way to the front of the truck. We went ahead and route our wire up over the frame rail, and we just followed the factory wiring harness up across, and we followed in behind the gas tank. inaudible 00:08:48 got past the tank, we just back with the factory harness and plumbing. We've tied it to some of the tubes that go up to the fuel lines and go to the front of the vehicle. You want to pay special attention when you go by anything like a drive line, make sure you've got it tied so it can't come around and hit the drive line. We went across up over the axle, tied it to the crossmember, paying attention to keep away from your steering linkage and your steering arms, tied it to the bottom of the shroud away from the fan. Then, we've come up across and we come out the front in the grill. Now that we have our wire run out to the front, if you're going to have a braking system, you definitely want to leave a loop of wire, so you can tie into it. We run the excess wire out the end here. I'm going to go ahead and strip it back after we separated it. You want to make sure you slide your boot for your connector over the wires before you start attaching anything, slide it back. We're going to strip our wires back. We'll start with our green wire, which is going to be our right turn marked with the RT, slide it in, and we'll tighten it up. Give it a tug and make sure it's tight in there. Then, we'll do our yellow wire, which is going to be the left turn, marked LT. You want to pay close attention you don't have any stray wires hanging out because if you do, it can ground out and cause a short. Then, we'll take our white wire, which is going to be our ground, marked GD, and we'll take our brown wire, the last one, one marked TM, which is going to be your trailer marker lights. On our case, our running lights on the back of the truck. Once you have those all secured, we're going to slide our boot back over. We'll take some electrical tape and we'll wrap it up, keep any grime and corrosion and water out of the system. Now, our kit did come with some loom, so we're going to go ahead and take that and we're going to place it over the outside of this just to protect it. Once you have it inside, take some tape and go around the outside. Take our self-tappers, we'll slip them into the hole there. We can pull our excess back, put our loop over here for our braking controller. That's going to do it for our look at and install of the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, Part Number RM-15267, on our 2005 Dodge Ram 2500.

Very good quality. Installation took 4 hours and that was due to locating tail light pins of which i had 2 on both left and right lights. Had to find 2018 jeep wrangler jl wiring schematics to find which one was the correct one to use. Where i could, I ran all wiring inside the frame members. That took more time than expected, but after that installation was a breeze. Refer to installation videos, very big help! After installation everything worked as expected between RV and Jeep! 693146

Overall this would be a five star review except for two issues. One being the wire provided was not 30 ft but was closer to 25 ft as I checked before using. I wired the same as the great etrailer video for my vehicle Cadillac SRX and ended up short. Fortunately I had additional wire and was able to complete the run. Secondly, the female spade connectors used on the diodes needed to be tightened as they were not very tight as provided by Roadmaster. These were all Roadmaster issues and of not fault of etrailer. Everything else looked of good quality. 428886

I like the coiled cable in RM-15267 At one time I owned an Airstream travel trailer that had a tow cable. The Airstream did not have a coiled cable and I had to tie it up with bungy cords to still allow flexibility while traveling. That lasted for one season and the bungy cords stretched out and the cable started touching the road, scraping off the insulation! The coiled cable in the RM-15267 prevents the cable from dragging on the road! 446459

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. 444983

Everything installed without any issues. I'm very particular so it took 2 days to complete everything. I'm sure a pro could do it much faster. Have towed the 4" lifted (and loaded) Jeep accross the Rockies about 6 times and everything is working perfectly!! Very happy camper!! 301003

The product is a good quality I installed this before. This time I needed 4-5 feet extra wire to route it properly. That's why I give it a 4 start. On the end its worked fine. 252634

Great kit for auto to motor home connection. Watched the video while installing the kit. Very good video and spot on for making the connection and explaining how to route the harness. 502226



- RM-15267

The wiring kit included all the parts listed and the video was most helpful with the installation. The installation went fairly easy until I got to the portion of running the brown wire from one taillight to the other taillight. The brown wire was not long enough. I had to splice another piece of wire on to the brown wire to make it longer. etrailer should consider making the length of included wire approximately 3 feet longer. That would have helped a lot with the installation. Also include a longer piece of the split protective plastic. Other than those two issues, I am satisfied with the product. 459131

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. 616795

Excellent company. Great communication, fast shipping and the products worked perfectly. I had some trouble installing this to my rear brakes, but that was my own fault. I didn't realize that the brake lights are grounded when they are mounted to the Jeep. So I kept testing the lights once they were hooked up, however they weren't mounted back on the Jeep. It wasn't until everything was mounted back on that it all worked without any issues. 305606

I ordered an entire setup to flat tow my Subaru with my RV. Having never done this before I was nervous about missing something I might need. etrailer made it very easy when I called them on the phone. I told them what I was trying to do and they made sure I had everything needed to complete the job. I was given a name and phone number to call the same person if I had any issues. When one of the boxes was opened it was missing two pins from the manufacturer. A quick phone call and they had them in the mail in a matter of hours. This kind of personalized service is missing in our ever changing world. It was a pleasant surprise to find it here. Great Job etrailer. I will favorably recommend to everyone. 493275

This product is incomplete. 4 feet more wire and five wires instead of 4 wires. The 4 wires are at least 4 feet short requiring you to purchase more from a local hardware store. This kit also does not combine the brake and turn signal requiring an additional wire. DO NOT be fooled by this kit. If you have a supplemental brake They want you to buy another kit that is impossible to install on the brake switch under the dash. I just added two relays at each taillight to keep the motorhome brake power from mixing with the Explorer power. Very simple and everything is easy to access. 519554

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. 711935

This kit has every thing you need to get your lights hooked up on your toad. Had to read the instructions a few times to make sure we were getting the right wires hooked up but after a couple of hours we were done. Worked as it is supposed to. This was on a 2019 Jeep Cherokee Trailhawk with the 4 cylinder turbo. Only wish they had the molex plugs to intercept the factory wiring but splicing the wires in was okay. 704062

Had it professionally installed. Nice, clean look on the front of my Equinox. Easy to hookup -the carabiner clips for the dead mans switch are quick and easy. The coil electrical line eliminates sagging loops hanging over the towbar. The battery charging line to car means no dead battery after a long haul even though the car was in ACC mode. Plus E-trailer had great technical help for any question we had before making the purchase. 703801

Next you'll want a tow bar to connect the base plate to your motorhome. The Roadmaster Falcon 2 part # RM-520 would be your best option. It's the easiest to use and our most popular option. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. For lighting you can use the diode kit, # RM-15267,...

  • Wiring to Flat Tow a 2019 Jeep Wrangler Behind a Motorhome
  • Magnetic tow lights, like part # TL21RK, do their job just fine, are less expensive, and don't require much to setup so they're not a bad option by any means. The only real drawbacks to them is that you need to set them up or take them off each time you change from towing to driving the Jeep. They also have a chance of scratching the Jeep's paint since they're being attached to its surface each time. We often recommend them if you're not going to be towing the vehicle very often or if...
