How to Install a Trailer Wiring Harness on a 2010 Jeep Liberty

Speaker 1: Today, on our 2010 Jeep Liberty, we're going to be taking a look at and showing you how to install the Tekonsha T-One Vehicle Wiring Harness with four-pole flat trailer connector, part number 118554.This is what our wiring harness looks like when it's installed. We have plenty of length. However, if there was more that you needed, it's folded up on the back side of the hitch here, just zip tied. You can see it has a dust cap that's connected, so you don't lose it. Whenever you're not using a trailer, to keep it from dangling, you just hook it on your ring.Now, this is what you're going to get in your wiring kit. It's going to have your connectors for both your tail lights, plug into your existing connections.

It's going to have your feed for your trailer wiring. It's going to have your black wire that runs off of your converter box. What's good about this converter box, it's going to help your vehicle from any back feed from your trailer, if your trailer may have any wiring issues. You also get a hardware kit for all your other connections.To begin our installation, we're going to remove the driver's side tail light using a 10 mm socket. Gently pull this out from the vehicle.

Then, what we're going to do, is we're going to remove this wiring harness right here. Now, we're going to repeat this on the passenger's side.Now, what we're going to do here on our driver's side, is we're going to take our yellow and brown wire, and we're going to connect it into the existing wiring harness that we took off of our tail light. First thing we're going to do here, is we're going to strip back this black wire that goes to our converter box. You want to take your black wire that comes in your kit, and strip one end of that. Your kit does come with butt 00:01:44 connectors.

However, because it's going to be living outside of your vehicle, I'm going to swap them out with heat-treat butt connectors. You can find them here at you have it in place, go ahead and crimp it down, and you're going to connect your black wire that comes in your kit in the other end. Again, crimp it down. We're going to take a heat gun ..Next, what we're going to do, is we're going to take all of our wiring .. and we're just going to drop it down right through the bumper here, like that.

Next, what we're going to do, is we're going to mount our modulator right inside on this panel, but first we want to make sur it's clean of any dirt, so we get a good contact and it sticks good. I'm just going to take some rubbing alcohol. Now, what we're going to do is we're going to peel this off. Now, you want to make sure your wiring side is facing down. Once you get in place, push on it a few times.Next, we're going to take our white wire and our self-typing screw that comes in the kit, and we're just going to mount . right in there. Now that we have all of our wiring connected, down on the bottom through our bumper, we're going to go ahead and hook back up to our tail light, and we're going to put our tail light back in place.Once we ran our wiring down, and I ran it across, I noticed that this wiring was close to this metal edge here. What I don't want to happen is a I don't want the metal edge, if any wind moves this or anything, to wear that thin. What I did, is I took some black wire loom here, some extra that we had laying around, I'm just going to tape it, just like that, so that the metal edge is off the wires.What I did is I took my four flat, and I ran it above my hitch, and just zip tied it to the back of the hitch here, so that I have extra wiring, if I need it. My other wiring that's going over to my passenger side, I just zip tied it along the back, wherever I could find a spot to put it. Now, we're ready to go and hook up our passenger side.Next, we're going to take the passenger side wiring harness here, and just feed it up, through the bottom of the bumper. Once you've pulled up all the rest of your hanging wire, up to the top through the bumper here, what I'm going to do, is I'm just going to wire it up and zip tie it together. Now, we'll take our existing wiring harness, and plug it into the wiring harness kit. We'll take the other end. We'll hook it into our tail light. Now, we'll put our tail light back in place.Once you get your passenger's side tail light hooked up, you want to check to make sure your wire is not close to your exhaust here. Next, I'm going to run the black wire to the front of the vehicle. Let me do that real quick, and I'll show you how I did it.I ran here, just attach to the body there. I ran and found the hard line, connected it there, so I could stay away from the shock here. Once I zip tied here, then I came up here to the back of the tank here, and I zip tied it here because next I'm going down. I didn't want it to go interfere with the spring here. Attached it there. Just ran it through the existing wire hangers here with a couple zip ties.Then, I just ran along the frame here to these hard lines, attached to the hard line here. I also attached it here, to stay away from this. Again, attached it there to the hard line. Attached it right here, so I stay away from the exhaust. Now, since this area's kind of tight, what I did is I just found an airline tube laying around the shop, dropped it down through my engine compartment where I wanted to run the wire, stuck the end of the wire into the tube, put a little tape on it, and started pulling my wire up through it. Now, what I did is I fed it up this side over here to try and keep it away from the engine as much as possible.What I did is I zip tied here, just along some existing wiring. I ran it up right along the outside here, again zip tying it to the existing wiring. I did this all the way up the battery, positive side of the battery, just to give it a cleaner look.Next, you want to take your fuse holder. We're going to cut it in half. You want to strip both sides of it. You're going to connect your ring terminal on one end. Then, we'll use another heat shrink butt connector. Place it on the other end, crimp it down. Next, we're going to cut our black wire. We're going to strip the end of it, and we're going to put it in the other end of the butt connector. Crimp it down. After you get your connections good, we'll go ahead and heat it up, and shrink that down.We'll take a 10 mm socket, move this nut right here on the positive side of the battery cable. Then, we're going to take the ring terminal end, put it on that spot, replace your nut. Tighten it down just enough so it doesn't move. Once you got that back in place, go ahead and put our fuse in. inaudible 00:07:45 the cap. It's always a good idea to check your wiring, to make sure it's working correctly. Either hooking up to your trailer . we'll be using part number I26. Running lights. Left blinker. Right blinker. Brakes.That'll do it for the Tekonsha T-One Vehicle Wiring Harness with four-pole flat trailer connector, part number 118554 on our 2010 Jeep Liberty.
