How to Install the Roadmaster Diode 7 to 6 Wire Coil Kit on a 2015 Jeep Cherokee


Today in our 2015 Jeep Cherokee, we'll be taking a look at and installing the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, part number: RM-15267. Here's what it looks like once it's installed. It's is going to have the diodes to protect your electrical system in your vehicle. And it's going to make hooking up to your trailer very easily without having to run separate set of lights back to the end of the vehicle for your brake and turn signals.This is going to be installed at all times. And the only time it's going to be active is when you plug into your RV. What's nice about this kit is it has diodes.

So it's not going to allow anything to backfeed into your car's electrical system, causing a short. Not a Cherokee. That's very important because they're very sensitive to shorting or any kind of sparks in the wiring can take out a computer. Not with our kits. It does come with a 7 to 6-way Adapter so if your RV has a 7-pole connector, then your vehicle's going to use a six...

This will swap it over so you can use it that way.We'll just snap into position, you'll plug this into the back of your RV, and you're ready to go towing. Now let's go ahead and show you how to install it. So your Kit's going to consist of a roll of wire. It's about 30 feet of wire. It's going to run to the front.

Four diodes, some zip ties, a butt connector, and a ring connector. It's going to be a little bit of loom that we can use in the front to cover our wiring. It's going to go to the RV. We're going start by removing our passenger side tail light. We'll take a T30 Torx bit, take out those two screws, set those aside...

We're just grabbing a light. Pull firmly. We're going to push down on this tab to release our plug. Set our lights to the side.Started by taking a self-tapper and we're going to attach it in here so we can use this as a grounding point for our test light, and later, we'll use it for the ground on our wiring harness. Now we can put our ground from our test light on there. We're going to need to reconnect our light because it doesn't work unless it's plugged in. So we can test it. You want to use a low voltage. an LED style test light, because these Jeeps are very sensitive to any wiring spikes. And don't plug in or unplug anything while the vehicle's running. Wait until it's shut off and everything is turned off before you disconnect it. Now the white with a yellow tracer. It's going to be our turn signal and brake light. These are our combined brake and turn signal. So, that one is one we're going to cut.Now we can take our stripper, strip back about a quarter of an inch of the wire, twist it. We're going to take it and fold it in half to double the size of the wire. And we'll do that on both sides. That way we have enough there to grab it inside of our connector. Take our supplied spade connector. We'll slide that over up into position, then we'll crimp it. We're going to tug to make sure it stayed. I'm going to do the same thing on the other side here. And before we put our diode in, we're going to go ahead and. We figured out the other one that we're going to use. It's going to be the white with the gray tracer which happens to be the one right next to it.We're going to do the same thing with that wire and put on two terminals. Then, we can attach our diodes. Now we'll take our wire with the yellow tracer, we'll plug that into the single side of our diode. Then on the other side of the diode, there's two outputs. We're going to put one side of that yellow one on that, and we'll do the same thing for our white, with the gray tracer. Always want your single side pointing to the bulb.Now, we can take our 4-Flat wiring, and we're going to fish it down between the body and the bumper. Going to let it drop out and we'll pull all that through. We're going to be sure not to let it get knotted up. Now we're going to separate out our wires. Our white wire is going to be for the ground. It's going to go to that right there. The green will go to our brake and turn signal and the brown is going to be for our marker light. The yellow is not going to be used on this side, so we'll just cut this back.We can strip back the white wire. We're going to put our supplied ring loop connector and we'll crimp it. We'll do the same thing with our brown wire. About a quarter of an inch. And those two are going to receive spade connectors. We'll give those all the tug. Now the green wire. It's going to go to the brake and turn signal, which is going to be our white with the yellow tracer. So we'll snap that onto the other side of our diode.And the brown wire will go on to the other diode. Now we can attach our ground. We have our ground nice and secure. We're going to put a zip tie around these two to hold them together. And we zip tied them and we cut off the excess. And we get a little bit of silicone. And we'll just take a little bit and smear it around the ends. I'm going to take a small screwdriver and we can help spread it around. I want to make sure you get it all around the outside of the connectors. Then we'll take one zip tie, and we're going to tie our wiring harness to our 4-Flat wiring just to keep everything intact.Now we can reattach our light, snap it back into place. Then we'll slide our light back into position. We're going to make sure we tuck everything down inside and we can replace our two T30 Torx bolts. Now we can go on to the other side. We're over here in the driver's side. Now we're going to need to get our wiring from the other side, route it underneath the car and back up. To make that easier, we're going to take a piece of air tubing. Just push it down inside. If you don't have a piece of air tubing, you use a coat hanger or a piece of hard wire. You're going to come out the bottom. We ran a piece of tubing on the inside of our bumper.We're just going to attach it. We'll pull it through. We want to make sure we tie our wires up so they're away from the exhaust. Do the same thing on this side. Now we attached our wire to the piece of tubing that we ran up the inner part of the bumper cover here. You're going to pull this all the way up through. And then we have our wire run up to the top. Go ahead and put a zip tie around it to keep it in place so it doesn't fall back down. Now, we're going to need to unplug this light. Pressing in on the tab, sliding it back so we can get all this covering off the outside of the wiring.We can plug our light back in and we'll test for our other two wires. Now we've tested our wire and the white with the green stripe on it. It's going to be our brake signal and turn signal. Give those a tug. Now the other wire we're going to use, it's going to be the white with the yellow tracer. That's going to be our marker lamp. Now, we're going to need to fold our 4-Flat wiring. We're going to have to separate it. We use a knife, carefully slide it in between. We need to gain access to the brown wire and our yellow wire. The green wire is going to stay intact because that's going to run up to the front. That's from the other side.Now our yellow wire, where it comes up, was a dead wire on the other end, so we're just going to snip this off back over to here. Strip that back and we can put one of our blue spade connectors on the end. And our brown wire. We're going to cut that one in half, strip back both halves. Now we're going to take a yellow spade connector, twist those two together. It's going to go on there. And we'll crimp that one into place. Now we'll take our diode. The wire with the white, with the green is going to be our brake.The other end is going to go on one side, torque diode, and the yellow wire goes to the other side of the diode. That's going to be our brake and turn signal. Do the same thing with our white with the yellow. Single side towards the bulb. The other half will go to the one side of the back half. And the brown wire we spliced together will go on the other half. Now, before we silicone this up, we're going to take our wire and drop it back down into the fender well, so we can route under the vehicle to the front of our car.Apply some silicone and we can plug our light back in. Then we'll tuck our wires down inside, take our two T30 screws, and we're ready to go to the bottom side of the car. Now we have the wire we pulled back down and we're going to run that to the front of the vehicle. And we'll just route it along the factory wiring and plumbing as necessary. So we ran our wire up over the cross member in the back, over the rear differential brackets, zip tying it all the way. We came across and followed our brake line down and around.We went ahead and ran it through the inside of the skid plate all the way through. Came out of it there, went to the bottom of the skid plate here, all and up around, and we just tied it to our frame rail and we've come out through the grill. But you want to keep in mind. On this vehicle, we're going to be using an air break system, so we don't have to tie into our wiring. But, if you're using a braking system that requires electric, you'd have to make sure you leave a loop up top for your braking system. We're going to select a location to mount our 6-pole plug. I'm just going to mount it directly to the grill. So we're going to notch out. Couple of these webs here, take a pair of side cutters.That should give us enough room to slide our plug through. Then we'll mount that with some quarter inch bolts, lock washers and a couple of fender washers we picked up at the hardware store. First, we're going to wire our plug up before we push it back in. We need to separate our wires. Then before we begin wiring, we're going to go ahead and slide our rubber weather boot back behind the grill. Then we'll strip back our wires about a quarter of an inch from the back of our plug.It's going to be marked for your right, your left, your ground, your tail lights. This would be for a trailer brake if you had them. That would be for a backup lights, if you're going to use those. Or an auxiliary. We'll start with our white, which is our ground. Put that into the position marked. It'll say GD on it. Slide our wire in. I want to make sure you have all the wiring down. You don't have any stray wires sticking out. Then we'll tighten down that screw. Give it a tug. Then we'll go to the Brown wire. It'll be our tail lights, marked TM. Right there. And same thing.We'll take the green, which is going to be our right turn signal. This one right here RT. The last one we'll have is going to be our left. The yellow. Then we're going to this one right here, marked LT. You just want to double check and make sure that you don't have any stray wires sticking out to come in contact with any of the other sockets. Now we can slide our rubber weather guard over top of the wiring, take some electrical tape. We'll secure it to the back and we'll secure this side to keep any dirt and moisture that could get inside the plug.Once we have that taped up, take our plug, slide it back in, we'll take our quarter inch bolt, our fender washer and lock nut. And then we install it on the inside, make sure we have it centered up, and tighten it up. All we have left to do is test it and make sure everything works. Let me plug in our 6 to 7-Way Adapter and torque tester and we'll try our left brake and turn and our right brake and turn and our taillights. That's going to do it for a look at and install of the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, part number: RM-15267, on our 2015 Jeep Cherokee.
