How to Install a Roadmaster Tail Light Wiring Kit on a 2010 Ford Explorer


Today on our 2010 Ford Explorer, we're going to show you how to install the Roadmaster Bulb and socket kit with bulbs part number RM-155. We'll hook our tow vehicle up to the front here, we'll start by turning on the taillights. With those working, let's check the left blinker, then our left break. Now our right blinker and our right break. Now as you can see, we mounted our plug in the position we went right on top of the bumper structure there. That way we wouldn't have any issues once we had everything on and trying to get it installed. WE're going to take care of getting our bracket mounted for where our wiring's going to go up here in the front.

Now a lot of times, like this bracket on the top side, we need to elevate it just slightly, so we just took a little piece kind of bent it up there to where it'll kind of elevate it up to where it'll appear out from behind our bumper. Now for the socket wiring kit that we're putting in, we need this to be connected up there at the front. It needs to make a detour by the breaking system that we're using and then head to the back of the vehicle. What we're going to do is just take the majority of it, pass it right down through to where we can find it on the underside of the vehicle, get that ran back there where we want it you can see it just pop out there below the car. We'll take our loop, we're going to leave a little bit up here on top so we can get that connected, then just run it right back. Slack out to the mean, there we go, and over there to our bug side.

I'm going to pass that thought he bracket and we're going to be trimming that off just behind that inaudible 00:02:10 plug. We'll bring in the rubber cap that's on the back of the socket. That's going to slide over all four of our wires. Now we need to strip the end off of each one here. Then we'll put them in their respective spots here in the back. The white wire, that's going to be our ground.

Next one we have is TM, that's trailer marker, that's going to be our brown wire. Skip one there, we're going to go to RT, that's the right turn signal, that will be our green wire. Then finally our yellow wire, that's going to be our left turn signal. Now while it's not a necessary step, since these wires are going to just kind of be hanging out there exposed, you'll be able to see them behind the grill, let's take some electrical tape and just wrap them up as neatly as we can here. Now up here on the top, you can see we've just routed our wire right here. I'm going to use a zip tie just to hold the slack in it that we need right here on top. Now we're going to start routing our wire towards the rear of our vehicle.

We want to avoid any significant sources of heat, any pinch points, any sharp metal edges, anything that might damage the wire essentially. See how we're just kind of going over top of that pass shaft location, we don't' want it to get near there. We'll go right up from there into kind of the ear the spare tire is. Now let's use a couple more zip ties. Now we'll trim the plug end off of our four pull wiring, then we'll tart pulling each wire apart to separate them. Now we'll use our green, our brown and our white wire, we're going to run this up behind the passenger side tail light. To do this we're going to use a little pull wire. We've got airline tubing here, you could use a coat hanger, stiff piece of wire, but you just want to tape the three of them off. That way when we remove our tail light, we'll be able to pull them up to us. Now we'll stick them up in the small slot here and kind of direct it up towards the bottom of our tail light housing. Now we're going to take the two screws out of the side of the tail light here that require the 8mm socket. You want to pull that housing out. Now we want to separate the two clips on the outside here to kind of hold that tail light in place. Now let's pull our plugs off the backside here. They've all got just little push tabs on them. Let's set those aside. Now let's bring our pull wire on through. Now with our housing off, you can see we've pulled that lower light out and we're going to go right about here and drill just a small pilot hole in. When we do this, we'll kind of hold everything upwards, that way any particles will have a better chance of falling down and hitting the ground rather than going inside of our light. Now let's use our 1 inch hole saw and finish making our hole. Now let's take our socket and kind of bend our tabs out a little bit. For this application, we've got to be pretty careful about how we put it in there. Our bulbs are going to want to touch so we're going to put half of the socket inside of the light and we're going to use these teeth on the other half of the socket to keep it from going in. We'll bring about the top half of the teeth in, we'll let those make good contact as you can see right there. Then we're going to use the bottom teeth to kind of hold out on it slightly and we're just going to seal that up with some silicone to give us a nice seal that'll leave our bulbs separated just enough to where they'll both work properly on the front side. Now I'm just going to use some RTV silicone, we're going to go around there really well, make sure it gets a good hold. All right, now that should do it. We'll let this one sit to the side and let that sealant have time to kind of firm up while we take care of drilling out our other light. Now that we've got our sockets installed in our lights, let's get our wiring ready. We're going to start by taking just enough brown wire for what we need here. We're going to strip both ends of that back. Kind of place those together and give them a little twist to kind of make them from two wires into one wire. Yellow butt connector's going to slide down on there, get it crimped down. Anytime we make a crimp, we want to make sure we've got good connection there. Let's do the same for our white wire here. Now for the green one, we're just going to trim that off. Now I need one end of this, we'll strip it, and this one's going to get one of our blue butt connectors, slide that on and crimp it. Now for your green wire, I recommend tucking it down here because we don't want it to fall back in and disappear on us. The other ones are going to be kind of held in place by the other wires here. The end of our wires here where we still have our fish line attached, I'm going to trim the green off, leave the brown and white on there. Then we'll wrap that right back down to the underside of the vehicle. See if we reach under, we'll be able to find it there. We're going to pull that brown and white slack back down through. Now let's strip the end off of each of the wires coming from our light. The black one, I'm going to strip it off extra long and I'm going to fold it over. THat's going to give that yellow but connector more meat or more wire to grab on to. Do the same thing for my brown wire and then we'll strip off just a normal length for the red wire. Our red wire gets connected to our green wire. That's going to be for our passenger side turn signal. The black wire, it gets connected to our white wire, that's going to be for our ground. Then lastly, the brown wire, it gets connected to our brown wire, that's for our running lights. All right, I'll just use a little tape and wrap those up. All right, now we're ready to put our tail light back in. Right back into it's spot. Now we're going to add our yellow wire onto the brown and white wire that we passed out from under the car. Let's get these over to the driver's side. We're just going to run them right along that bumper structure there. We'll just keep working it on across here. We're just going to use zip ties as we go to keep everything up nice and secure. Right over the frame rail there. All right, perfect, now let's make our connections up there. Now for our wiring on this side, we're going to take our yellow wire, we'll cut that off, strip the end, and on this one, we're going to add a little blue butt connector. Now let's do our brown wire. Same treatment on this one. Now for the white one, we're going to do it the same way we did the white one on the other side. We're going to strip it, or cut it, then we'll strip both ends. This is going to get a yellow butt connector. Now let's take about 5, 6, 7 inches of the tag end, the one that's connected to our full wire. Cut, strip, this time we're going to add on a rain terminal. Then we can take a self-tapping screw, we'll get it anchored right into the body. Now again, our black wire that's going to go to our white wire and since we've got that larger butt connector, we need to strip some extra off. Our brown's going to go to our brown, and our red to our yellow. Now we're going to tape this side up just like the other side. We'll just slide our connectors back on. Get our bolts started and get them secure. That's going to complete today's installation of the Roadmaster bulb and socket kit, part number RM-155 on our 2010 Ford Explorer.
