How to Install the Roadmaster Diode 7 to 6 Wire Coil Kit on a 2007 Jeep Wrangler Unlimited


Today on our 2007 Jeep Wrangler Unlimited, we'll be installing the Roadmaster Diode 7-Wire to 6-Wire Flexo-coil Wiring Kit. This is part number RM-15267. The Roadmaster tow bar wiring diode kit allows you to use your vehicle's tail lights and wiring system while preventing feedback from your RV. It lets you wire your vehicle to accept your RV's tail, brake and turn signal lights for flat towing. Here's what our kit consists of, the most important part being the four diodes that we're going to use to tap into our vehicle's stock wiring, so we can have towed vehicle lights behind our RV. We have a bundle of four pole flat wiring here. We'll run this to the front of our Jeep using this connector here, which is a six pole, where the flexo wiring here will connect to.

Then we have the standard seven way RV flat which will go in the back of the RV. We have several zip ties here to secure all of our wiring, and some wire loom nets included as well in case we need to protect it from any moving parts or sources of heat. We also have an optional bracket here in case your tow bar base plate doesn't already have a spot to put your connector here, so this will allow you to attach it. It even comes with the included hardware to mount it. Now that we've gone over what's included with the kit, we'll go ahead and show you how to install it. We're going to begin our installation by doing some pre-assembly here before we even put it on the vehicle.

We'll take our wire here and we'll separate the ends a little bit. With our wires all separated, we can strip off about a quarter inch or so of the insulation. We'll take our protective cover here off the back of our connector, insert our wires into it, slide it down over our wire, now we can make our connections to our socket here. We'll loosen the terminal for the ground. Take the white wire, which is our ground, twist it together, insert it and then we'll tighten down the screw. Then we'll go to our left turn signal, we'll take the yellow wire, twist it together, insert that, tighten down the screw.

Do the right turn signal, take the green wire, tighten the screw. Now we'll find the tail lights or side marker lights, which is the one here marked TM, take our brown wire, tighten up the screw. Check all of our connections, make sure their nice and tight. We'll slide our dust cover back over, just like so. Now we'll take some electrical tape and we'll go over our seal here, just so we have a nice, weather-proof connection to keep any moisture from entering and keep any corrosion from forming.

We'll go down a couple of inches, down the wire, just so we don't have color wire being exposed in the front of our vehicle as well. It just helps tidy up the installation and makes it look really nice. Now right here, on our base plate for our tow bar system, we have a really good spot to mount our bracket here. You can see the holes line right up to it, but we need to make a spot for our wires to pass through underneath the vehicle, so right in the center of it, down here on our rock shield, I want to drill a small hole. Now we'll take the end of our wire here, feed it up behind our face plate and we'll insert it into this hole here and we'll start pushing it back, then we can pull it through. Now we can grab a couple of self-tapping screws and secure our connecting point to the front of our base plate. Now with that done, we have a real nice solid connection on the front of our vehicle to secure our connection between the motor home and our Jeep. Now we're going to go ahead and run our cable towards the back of the vehicle. Just in keep in mind, we'll want to avoid any moving parts such as the drive shafts, the steering linkage, the axles or any sources of heat such as the exhaust. Once I have it routed, I'll show you the direction that we went. I started off by going over the front sway bar here, following the existing wire loom for the vehicle wiring harness. Secured it through a zip tie here right behind the sway bar. Go ahead and snip off the excess right now. Then I have another zip tie up here securing to the wire loom when it starts to curl up above the engine mount here. Then the wiring harness goes to the top of the frame in this area just so it has some space between the catalytic converter because it gets awfully hot right there, so I have it secured to the top of the frame with another zip tie to the wiring harness. Then once the wiring harness gets past this control arm point attachment, it goes back to the inside of the frame, so I have it secured with another zip tie right here. Then another one right here before this cross member where the transfer case mounts to. At this point, we're right in front of the gas tank. The gas tank's got a nice skid plate on it so I followed the top of the gas tank and went behind this skid plate, over these cross members, all the way back and then our wire comes out about at the rear our gas tank here. I have it secured to a wiring harness here and then again to the filler neck of our gas tank just to help hold it above the differential. From there, we go back and up over this cross member in the rear of the differential, secured with another zip tie right here and then goes over, secured with a zip tie to the shock mount. We go up over the frame rail here and we dropped it down on our passenger side, right behind the tail light area, and this is where we'll pull it up into the vehicle to make our wiring connections. Now before we continue any further, we need to remove our tail light assembles on both sides of the vehicle. You don't need to remove the outer two, you only need to remove the inner two. We'll take these two out, then we can take our tail light assembly, slide it inwards and just pull it out like that. We'll do the same on this side as well, by removing the two inner screws and we'll slide it and pull it on out. Okay with our lights out of our vehicle now and just resting off to the side, we need to bring our wire up. Now there's a little panel here on the inside, just peel it back a little bit and you have full access down below the vehicle, right in there. Got our wires up inside now so we can fold back this little panel here, just like so. Now just like we did on the front, where we split the wires to connect to our six pole round connector, we'll separate our four wires just by clipping them here, in between each one a little bit down the wire, and we'll pull our wire back so we have individual wires to work with. To make ourselves a little bit more room, let's disconnect the right side tail light here first by pressing on this tab here and pulling out the wire. We'll set this aside so we don't damage it. Then we'll undo some of this electrical tape on our wire loom here. We can pull it back. Now I have some nice, clean wire to work with here. Now I used a test light to determine that this yellow and white wire here is our right side turn signal, so we'll ahead and cut this wire right here in the middle, and we'll strip off about a quarter inch of insulation on either end of it. Now we'll grab one of our diode packs here. We'll take off the side for the output and we'll stick it right over here on the side going to our tail light assembly. We'll grab a wire crimpers here and we'll crimps that into place. We'll do the same on one of the spade terminals off the input side. Put it on this end right here and we'll crimp it down. We'll take our green wire, which is our right turn signal, measure off about how much we're going to need, we'll cut off the excess and set it aside. Go up about a quarter inch, tape the remaining loose spade terminal, stick it onto our green wire like so, crimp it on down. Take the green wire, connect it to the input side of our diode pack, same with the yellow and white wire that went closer to the front of the vehicle. The connector end will hook up to the output side of our diode pack, just like so. Now we can take the purple and white wire here, which is our tail light wire, we'll cut that right in the middle and we'll strip back a quarter inch on either end again. We'll just take one of the blue ones off for now, stick it on, crimp it into place. Take another blue one off of it, stick it on that end, closer to the connector, crimp it down as well. Now we can take our diode pack, plug the output into the connector side. Get rid of the yellow connector for the time being. Plug the other end of the wire into one of the input sides, just like so. At this point we can remove the protective cover for our double sided tape and stick our two diode packs together, just like that. Now we'll take our brown wire, which is our tail light signal wire, cut off about how much we need. We'll save the remaining part, we'll strip off one end of it, about a quarter inch or so. The other brown wire that we have going to the front of the vehicle, we'll strip off about quarter inch or so of it. Now we'll twist these two wires together like so, take the yellow connector we have, insert it, and crimp it on down just like so. Now we will connect this wire to the remaining input terminal on our tail light wire diode pack, and the extra brown wire that connected to it, we will drop this down the same hole we let our wires up through to begin win. We'll reinstall the insulation piece, pushing it back down into it's position. Now for our white wire, our ground wire, we'll measure off about how much we're going to need, just to make a connection with a self tapping screw to this back panel here inside our tail light housing. Back in there, there's a thinner liner behind it, and that would be a perfect spot to attach our ground to, and it's directly to chassey ground. Measure off about this much here, it should be plenty. I want to strip back about a quarter inch of insulation there, install a ring terminal and I'll crimp it down into place, just like that. I'm going to stick my wire over my self-tapping screw, get my screw gun on inside the tail light housing and install the screw. Now we need to drop our yellow wire down the same path the wires came up and the path that we dropped our brown wire down. This will be our turn signal signal for our left side. Now with all of our connections made, we can go ahead and take some electrical tape here and we will wrap up our diode packs with some electrical tape. This will ensure that we have many years of service without a problem. Okay, that nice little bundle there, we can go ahead and reinstall our tail light assembly on this side. We'll reinstall our electrical connection, making sure it snaps into place. Slide these tabs in here behind this lip on the body, push it in like that, and we'll reinstall our two screws. Now we can take our yellow and brown wire that dropped down from the passengers side and we'll route them over to our drivers side. Going over the frame rail here again, up over this exhaust heat shield, and we'll go up over the frame rail on the other side too and we can secure them with a zip tie to this wiring harness right here. This will keep it up and out of the way of any moving parts or any sources of heat. We'll trim up our excess. Now we'll push our wires up and to the inside just like we did on the passenger side, through 00:14:43 that little Styrofoam space. We'll pull our wires up, just like so, and we'll push back down on our insulation. Perfect, we have plenty of wire to work with now. Now before we test our wires, let's peel back some of this insulation and electrical tape and wire loom so we have something to work with here. We've determined that this orange and white wire is our taillight wire, so we'll go ahead and cut that in half. Strip off about a quarter inch or so from our orange wire on either end. Take our diode pack, install one of the blue connectors, we'll crimp it all into place. Take another one of the blue connectors, crimp it down as well. Take our brown wire, which is our tail light wire, measure off how much we're going to need, cut off the excess, strip off a quarter inch or so, take the final blue spade terminal from our diode pack, install it over the wire, grab our diode pack at this point, connect the brown wire to one of the inputs like so. The orange and white wire will go to the other input, and we'll connect the output to the side going to our tail light. Now we'll take this green wire here, which is our turn signal, cut it roughly in the same spot, strip back a quarter inch or so on either end, grab our final diode pack, install blue spade terminal connectors on either end. Take our yellow wire, cut off our excess, strip off insulation. Take the final blue space terminal connector, install it, and we'll crimp it down . Take the diode pack, connect the yellow wire to one of the inputs just like so. The green and white wire to the other one, and then the green and white wire that's closest our tail light assembly plugs into the output, just like so. Now take off our tape from the diode pack, stick it to the other then, then we can wrap them both up together in electrical tape, securing our connections. Now with all of our connections made on our drivers side and our diode pack here all secured up together, we can reinstall our tail light. Push all our wires back inside the vehicle, line those tabs back up on the outer edge, push it into place, reinstall our two screws and we'll fasten them down. We have a trailer tester installed on the front of our Jeep right now, so we'll go ahead an test all of our functions to make sure everything is working properly now that we've completed our installation. That completes our installation of the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, part number RM-15267 on our 2007 Jeep Wrangler Unlimited.
