How to Install the Hopkins Custom Tail Light Wiring on a 2014 Lincoln MKX

Today on this 2014 Lincoln MKX, we're going to install part number HM56002. This is a Hopkins Custom Taillight Wiring kit for towed vehicles. First off, we're going to open up the tailgate to get access to the taillights. We're going to use an 8mm socket to remove these bolts. We'll go ahead and just work our light loose, there's two pins right that's holding it in place after you unscrew it. We'll disconnect the wire harness right here, we'll push on this tab and pull it apart.

We'll repeat this for the other side. Now we can go ahead and start working with our new wire harness. Quick little tour, our 4-Pole end will be ran eventually up towards the front of the vehicle. This wire harness with the green wire will be ran over to the passenger's side. The shorter wire harness with the yellow wire will go over to your drvier's side. First off, I'm going to take our 4-Pole wire harness and we'll go ahead and drop it down between the bodywork and the bumper cover on the driver's side.

This is a really tight inaudible 00:01:21 between the bumper cover and bodywork so we're actually going to loosen up these fasteners here to give us some working room. Now these are just basically plastic rivets but you can use a Phillips head screw to back out the centers. Then loosen them up and pull out the rest of it and set it aside and put them back in later. All right, we'll use this very fine screwdriver to pull up the rest of this. We're going to pull up our bumper cover just a little bit and drop it down through. We'll take our Diode box and we'll go ahead and route it, our wires up through here and into the area right below the light.

While we're at it we'll go ahead and connect these two matching ends together until they click and the remaining end will eventually go back to our taillight. Let's just set that in there for now. Then our other half of our wire harness, we'll go ahead and hide underneath here and go over to the passenger's side. We're going to aim for our wire harness to be about right in this area here underneath our bumper cover and then our rivets will hold everything in place. Let's go ahead and make our connection back here as well. All right, we'll go ahead and bundle up our wires with some zip ties that come with the kit.

Go ahead and bundle up our wire on the passenger's side and then we'll go ahead and reinstall our rivets. Now look underneath to go ahead and check our wires that ran across and actually we can see them pretty good so we'll use that to our advantage and let's go ahead and zip tie them to the factory wire harness right here. We'll go ahead and cut off our tails to our zip ties. At this point we can go ahead and take a moment to reinstall our taillights. Our other half of our wire harness will go back into the taillight and we'll go ahead and push it back into place. Put the little plastic rivets in if you'd like. All right, at this point we can go ahead and take our wire at the 4-Pole end and we'll go ahead and route it up to the front of our vehicle. When we do that we want to stay away from anything moving like the suspension components or anything hot like the exhaust. Once we get up to the front, we want to stay away from anything moving like steering components as well. We'll go ahead and show you how we ran our wire and then we just continued on over the top here, zip tied to this line here and then we found the wire harness on top of the sub-frame for rear suspension and zip tied to it and just followed it on down. Went around the gas tank, came back over here by the parking brake cable and zip tied it and used some empty slots that's holding here for lines and just followed that on through, we zip tied as soon as we could. Next what we're going to do is take our wire and we'll go ahead and pull it up towards the top of the engine compartment because some supplemental braking systems need access to this wire. We'll go ahead and pull it up towards the top and to do that, we're using an old piece of air line tubing, this can also be any type of wire that can hold its shape and you run it down from the top to the bottom. We're going to attach our 4-Pole to our wire pull and just pull it on up. Mine's going to go around the brake lines so I'm going to guide it by hand first to go through there and that should be the only obstruction. We'll go ahead and pull the rest to the top. I'm just going to take my wire here and I'm going to route it up and around the battery and around the box here as well, maybe around the fuse panel as well. Then I'm going to go straight right back down in front of the engine and we'll come out to the front of the vehicle down by the bumper. All right, we've got it routed down for now, let's go ahead and take a few moments and we'll zip tie our wire to keep it from moving up here. Now when we pull down our wire, we made some adjustments so it wouldn't sit on the radiator hose and we hid it behind these hoses as well and we're just going to come straight down. Now we'll go ahead and route our 4-Pole wire harness to the center of our base plate on our vehicle. To help us go over a little bit, we're going to remove this plastic rivet and then put it back into place. This will also help hold our wire in place as well. Just catch the edge of the center of the rivet and just work it out. A small screwdriver works best to get it started and then a larger one or a trim panel tool will work to get the rest of it out. All right, I'm just going to move my wire past that rivet and then we'll put the rivet back in. All right, let's go ahead and route our 4-Pole on over to the center. We'll go ahead and attach our ground wire to this crossing bar using this provided self-tapping screw. Now this screw uses a 1/4 inch hex driver. Typically the sub-frame is not going to ground into the body so we just ran a jumper wire from our sub-frame assembly up to our body work right here. We just used a simple piece of 10 gauge wire, two ring terminals and some self-tapping screws, anything to get a metal connection from here to here will work. Also you could take the white wire extend it and run it up to the battery or a body ground somewhere else. Now our last connection, really, is just to go ahead and find a place to mount our 4-Pole wire harness. This is the bracket that comes with it and also comes with a cover. We'll go ahead and put the cover on first. It just slides over top and friction holds it in place and our bracket will just clamp around it, make sure you've got the cover route through this edge here, put it back over itself and just push it together. Now there are two screws that you can mount this to wherever you like on your vehicle. Again, this is going to be personal preference. It looks like it fits right in the grille here but what I think what I'll do since we don't really have any access to drill or anything, I think we'll just go ahead and use some zip ties to go through the slots and to this bar right here in the grille. Cut off our tails as close as possible. All right, once you're satisfied with the placement we'll go ahead and apply power to it to make sure the lights work in the back. All right, let's go ahead and apply power to it. First we'll go ahead and try the running light circuit. Now our right turn signal and now our left turn signal. We'll go ahead and take a look at our brake signal. All right, it looks like everything works. That will finish it for our install of the Hopkins Custom Taillight Wiring kit for towed vehicles, part number HM56002, on our 2014 Lincoln MKX. .
