How to Install the Roadmaster Diode 7 to 6 Wire Coil Kit on a 2017 Lincoln MKX


Speaker 1: Today in our 2017 Lincoln MKX, we're going to be taking a look at and showing you how to install the Road Master diode seven wire to six wire flexo coil wiring kit, part number RM-15267. Here's what our wiring looks like when it's fully installed. It's going to allow us to accept our RV lights and activate our Lincoln's lights in conjunction with that so when we're flat-towing our Lincoln down the road, people will know whether we're slowing down, changing lanes or anything because our lights will activate on the back at the same time that they're activating on our RV.Now, our kit is going to come with a six-way round plug at the front of your vehicle. And it's going to come with an umbilical cord to connect from your RV with the seven way end and then a six way round end for the vehicle. Our wiring is going to have some diodes and they are going to stay right behind our tail lights. We are going to have to splice into our wires.

The nice thing about our diodes is is it's going to prevent any kind of feedback that we may have on the RV side from damaging the electrical components in our car.Now that we've gone over some of the features and we've seen what it looks like, let's show you how we got it installed. I took my loom and I went in and put it on the end of my full pull wire. I left a big wad of it up here. We're going to leave it there for now and we're going to start routing the other end towards the front. I'm going to come behind the headlights, down towards the radiator.

I'm going to zip tie this temporarily for now just so that I don't have to worry about the wire falling down. Now, the wiring is going to be a lot easier and a lot easier to route if the fascia's not on the car. I would suggest doing your wiring whenever you do your base plate.Now that we have our fascia back on, we can go and start running our wire towards the back of the vehicle. And to help me get it there, I'm going to take a piece of airline tube. I'm actually going to run it down to the bottom of the engine so that I can catch up with it down at the bottom.

That way I make sure that my wire is going where I want it to go. I'm just going to start feeding this down until it reaches the bottom. Then I can attach the other end to my wire so I can pull it through. Just going to take a little bit of electrical tape and tape my wire to my airline tube so I don't have to worry about it dropping and losing my wire when I start pulling.Here's where my airline tube came out. I'm just going to start pulling it down until my wire comes down to the bottom.

I'm going to pull all the excess wire down, make sure it doesn't get hung up up top. Once we have all of our wire down, we're going to need to route this all the way back to our tail lights. Everybody's going to do it a little bit differently, but just want to recommend that you stay away from any heat sources like the exhaust or any moving parts that will damage the wire. I routed my wire, zip tying along the way, and routed it underneath this cover. Then I came out, went around the fuel tank, over the filler neck, and I went over the area in the back axle here. Then I actually went underneath my heat shield so that I don't have to worry too much about my muffler then I having it drop down right here.Now we're going to need to split each one of these wires. The easiest way to do it is to split them all the way back up to the bumper that way we have four separate wires. The easiest way to do this is if you take a pair of cutters and very carefully cut in between each wire, being careful trying not to cut it. Once we have a little bit of room in between the wires, we can start pulling them apart. You're going to want to split each one of these wires. With the wires ran to the back, we're going to gain access to our tail lights. We're going to open up our rear hatch. The way our tail lights are going to be attached is right behind this cover, we're going to have a fastener that we're going to have to remove.I'm going to take a flat blade screwdriver and pop that cover off. Then we can grab a T-25 torque's bit and we can remove that bolt. And with that removed, you're going to want to kind of wiggle the tail light back and forth. Once it loosens up you're going to want to pull straight back. We can go ahead and disconnect our electrical connector. There's going to be a small tab towards the back. If we push on it and then pull and release it. To make it a little easier to test, I'm going to remove the clip here on the connector so we can have a little bit more room to work with. Now that we have this one exposed and open, we're going to go and repeat that on the passenger side as well.We've build the tail lights out. We're going to need to test our wires to figure out which wire is for which circuit. I went in and turned my headlights on so we can figure out which wire goes to our tail light circuit. I'm going to take my test probe and I'm going to probe each one of these prongs and figure out the corresponding wire that goes to my tail light signal. It's going to be this bottom left one right here. It's just going to correspond with the purple and teal wire. We're going to need to remember that or write that down. Now on the passenger side we're going to be testing for the same thing. It looks like it's going to be this bottom left one here which is going to correspond with the white wire with the orange stripe. Again, we're going to need to remember or write that down.The next circuit we're going to test for is going to be for our brake light circuit. I went in and turned the headlights off and I have an assistant holding the brake down for me making sure that's the only lights that are going to come on. We can go ahead and start testing our wires. And it looks like it's going to be this bottom pin right here and that's going to correspond with the white and teal wire. Again, we're going to need to remember or write that down. And we'll test for the same thing on the passenger side too. That's going to be the bottom right, which is going to correspond with the gray and purple wire. Our brake light signal was this white and teal wire. We go in and check that wire. And we can see we are getting our turn signal circuit right here. And we'll go ahead and double check the right side as well.On the passenger side, if we remember our brake signal is the purple and gray wire. And if we check that pin, we can see that it's also activating our right turn signal. We're going to start on our driver side. Again, I'm going to take a piece of airline tube. I'm going to go down between the body and the bumper and I'm going to feed my airline tube down so I can grab the wires and start pulling them up. My airline tube here. We're going to leave our green wire down at the bottom for now. But we're going to grab the yellow, brown and white wires. Let me grab the end of them. Grab our airline tube and going to put a couple of them inside the airline tube and take a piece of electrical tape and secure it and start pulling our wires up. When you pull these up, you want to make sure you get all the wire pulled up and there isn't any bundle or wad that's getting stuck underneath.We're going to go ahead and start with our yellow wire, which is going to be for our turn signal and our brake. If we remember, on the driver's side that's going to be the teal and white wire. I'm going to go ahead and cut this wire in half and strip back both ends. I'm actually going to fold these in half that way there's a little bit more wire once we get ready to make our connections. You're going to grab one of your diodes and we're going to take the connectors off. We can take one of the connectors, put it on the connector end of our tail light circuit. Crimp it into place. Put another connector on the other end of that wire. And then we take our diode and the side that's going out is going to go towards our plug that plugs into our tail light and the other end of the wire is going to go into the inside, doesn't matter which side. And then we're going to take our yellow wire. We're going to estimate about how much wire we need. That'll be plenty right here. And we can strip back the end of that wire. Now we're going to take our other connector and crimp it into place. Then we can plug it into the other side of the end on the diode.Now we're going to be working with our brown wire which is going to be our tail light signal. On the driver's side it's going to be the purple and teal wire. We're going to do the same thing. We're going to cut it in half and strip back both ends. Again, I'm going to fold my wire to have a little bit more to grab onto with the connectors. This time we're going to grab the diode with the two blue connectors and the one yellow connector. We're going to start off with the two blue connectors and one of each is going to go on each of the wire that we just stripped. With those connections made we can go ahead and plug in the in and out. Again, the out is going to go towards the plug on our tail light. We can go ahead and pull off the yellow terminal. Set it aside. We're going to take our brown wire. We're going to need to estimate about how much we need again. This should be about plenty. We're going to cut this wire. This time we're going to hold onto the excess and we're going to strip back both ends. The end on the excess and the end that we routed up. And we're going to twist both of these together and combine them to one wire. And we can crimp on the large yellow terminal. Finally, we can plug it in.Now that excess wire, our brown wire, this is actually going to go over to the passenger side. We're going to have to route that back down. I'm going to drop my airline tube back down. And then on the other end I'm going to attach my brown wire. Before we move back down, let me go ahead and finish up up here with our white wire. Our white wire is going to be for our ground. We're going to need to connect it to some sheet metal. And they do provide us with a self-tapping screw. I'm going to estimate about how much I need. Cut it and strip back the end of it. Now on the end, I'm going to be crimping on a ring terminal that they provide in our kit. Then we take the provided self-tapping screw and just screw it right into the sheet metal right here. I'm going to be using a five sixteenth's nut driver to put it in place.Now we are going to have our brown wire run across over to the passenger side. Obviously we see that we don't have enough wire, but you can pick up some wire on our website by the foot using part number 16-1-1. Go ahead and strip back the end of our brown wire as well as the extra wire that we got. I just happened to have a little bit of green wire laying around. Now, in our kit, they do provide us with the butt connector to connect the wire, so you can put your extension in. But I'm going to be replacing that connector with a heat shrink butt connector since it is going to be on the outside of the vehicle and help provide a little bit more protection. Now, if you need some of these you can pick these up on our website. And crimp our wires into place.We're going to be using a heat gun to shrink down my connector. I just do want to mention that you want to be extra careful not to burn the wire or the connector itself if you are using an open flame such as a torch or a lighter. Now we're going to use the same method to get the other two wire back up to our passenger side. I'm going to take my airline tube and go ahead and start passing it down. Go ahead and attach my two wires to my airline tube. And then I can go back up top and start pulling them through. Again, you want to make sure you pull all the excess wire up. It never hurts to look underneath and make sure it didn't get knotted up and tangled.We can start with the green wire, not the extension, but the green wire coming off of our full pull wiring. And that's going to be for our right turn and brake signal. If we remember, that's going to be the purple and gray wire. We can go ahead and cut that wire in half and strip back both ends. Again, the out is going to go towards the tail light socket. It doesn't matter which end we put it in. Estimate about how much wire we need. Cut our green wire and strip it back. Crimp and put the terminal in place. Plug it into the end.Finally, for our extension, we remember this wire was originally brown and that's going to be for our tail light circuit. Now the tail light circuit's going to be that orange and white wire. We can go ahead and repeat that same process. All the connections made back here, we're going to tuck our diodes down as far as we can. We're going to put our connector back into the clips holding it, that way we can get our tail light back in place. We're going to go ahead and do that on the other side as well.We can plug our tail light back in. We can finally reinsert our tail light. Once we have the tail light, we can replace the screw holding it in. Finally, we can put the cover back in place. We can go ahead and do that on the driver side as well. You want to make sure you tidy up your wires that are underneath. You don't want them hanging down. You especially don't want them touching the muffler or anything really hot.Now, I put some wire loom around the wire and then secured it to the top of my vehicle and the frame on the bottom right here with a wire loom clamp. Now if you need some wire loom, you can pick some up by the foot using part number 459075-1. Now if you need some wire loom clamps like this, you can pick one up on our website using part number A0500. We're going to have the wire up our connector on the front here. We're going to have to split those wires again. Again, just take your pair of cutters. Be extremely careful and try your best to go in between the wires and not cut the wire itself. This time we don't need to strip it back. Don't pull them apart too far, just enough so we have some working room.Now we have them pulled back, we're going to strip back the end of each one of these wires. Before we start, I'm going to take my dust cover. I'm going to slide it over my wires. I'm going to push it back fairly far that way it's out of the way. Now we can grab our plug and we can start to wire up our plug. We can go ahead and start with our white wire. That's going to be our ground. We're going to find the terminal that says "GD". I'm going to loosen them up and take our white wire, insert it into the terminal and then tighten up the set screw. Now, if we come to the top, it's going to say, "TM." That's going to be for trailer marker, which is going to be our brown wire. That's going to be for our tail lights. We're going to do the same thing. Loosen up the set screw. Put our wire in and tighten it up. Now if we come to the bottom. It's going to say, "LT." That's going to be for our left turn. That's going to be that yellow wire. And finally, right next to that one, we're going to have one that says, "RT." That's going to be for our right turn and that's going to be our green wire.Now before I put my dust cover on and secure everything. I'm going to take a little bit of dye electric grease. I'm just going to put it inside the connection points in here. I'm going to take my dust cover, slide it over. The dye electric grease is going to help prevent some of the moisture and corrosion from building up on our connectors. If you need some, you can pick some up on our website using part number 11755. I'm going to take a little bit of electrical tape and I'm going to wrap my loom as well as the dust cover with some electrical tape to help prevent any kind of moisture or debris from getting inside and it'll also help hide the color of the wires in case that loom starts to move.Now, our base plate already has a spot to mount this right here. These two tabs are coming out. I'm going to take a couple of self-tapping screws and put them in place right here. You can go ahead and plug in the cord that comes with our kit. Then I'm going to plug the other end in to a tester so we can make sure our lights are working properly. So if I turn on the tail lights, we can see that those are working. Now if I turn on the left turn signal and the left brake light, we can see that's working properly. Now on the right side, we can see that's working as well. Now we know that our Lincoln is going to accept the lights from our RV.Now just to make sure that our Lincoln is going to have regular lights when we're driving it normally, go ahead and show you that our factory lights still do work. We turn on the headlights, we see the tail lights still work as well as the left turn signal, right turn signal and the brakes and both turn signals. With everything working properly, we're ready to hit the road.Now that everything's in place, I do want to mention if you are going to be using a supplemental braking system, you may be required to pick up a brake light relay, which are sold separately. And you can pick them up on our website using part number RM-88400. That'll finish up our look at the Road Master diode seven wire to six wire flexo coil wiring kit, part number RM-15267 on our 2017 Lincoln MKX.
