How to Install a Trailer Wiring Harness on a 2013 Dodge Journey


Today on our 2013 Dodge Journey, we'll be installing the Tow Ready T-One Vehicle Wiring Harness, part number 118536. All right. Now, we're here at the rear of the vehicle. We've already raised the rear hatch up. We're going to need to pull out both of the rear taillight assemblies. In order to do that, we'll need to remove a push pin here and a push fastener here.

To get these out, you'll simply take a flathead screwdriver, and you'll need to remove the center section. Once you get them started, you can either take another flathead screwdriver or a trim panel removal tool. We'll need to work the center sections out of them. Once we have both of the push fasteners out, go ahead and gently pull outward on the taillight assembly. There's two little pins here that you'll need to pull outward. Next, we're going to go ahead and disconnect the wiring harness connections from the backside of the taillight.

To do that, you'll simply push down on the locking tab and gently pull outward. Now for the smaller one, you'll have to lift up on the tab, so we'll lift up on this little tab right here and gently pull outward. We can go ahead and set our taillight assembly aside for now, and we'll go ahead and remove the passenger side in the same way. Next, we're going to go ahead here on the driver side, and we're going to take the four-flat wiring. We're going to feed it down behind the bumper cover.

We're also going to take this in, the green and white wire end right here with these connections and feed that down as well. Next, we're going to go ahead and take our wires here that have the brown, white and red on them. We're going to tie it into the factory connection right here, so we'll go ahead and line up our locking tabs. Push it in place, making sure that, that fully locks into place. Our other connection point here will be the white and yellow wires. Go ahead and line up locking tabs again on this side, making sure that it fully clicks into position.

Now, we're going to go ahead and take our black wire that comes with the kit. We'll need to strip a little bit back. We'll then be adding one of the yellow butt connectors to that end. Go ahead and crimp it down. We'll then go ahead and take our black wire that we just crimped the butt connector on, and we'll connect it to the black wire coming out of our converter box here. We'll go ahead and tape up our connection then. We can then go ahead and feed this whole black wire down behind the bumper cover as well as this wire here will be routed up towards the battery at the front of the vehicle. We will then go ahead and take a paper towel with a little bit of rubbing alcohol on it. I'm going to go ahead and clean off an area in here, so that our two-sided tape will stick to the body here. Go ahead and peel the backing off of our two-sided tape on our box. We can go ahead and adhere it to the body itself. Next, we're going to go ahead and take our white wire with the ring terminal on the end of it. We'll go ahead and attach it to an area of the sheet metal that's been doubled up using a self-tapping screw. Next, we'll go ahead and we'll plug our connections here back into the backside of our taillight assembly. Again, making sure that the locking tabs are secure. Now with our light back into position, we can go ahead and put our push fasteners back in. Then, we'll need to go underneath the vehicle. Now, we've gone ahead. We're going to use a section of old air line tubing to help route our wire up and over the bumper structure here, so that it helps it stay away from the exhaust as much as possible. We've gone ahead and taped our four-flat wire. Go ahead and pull it up into position. Next, we'll go ahead and feed our green and white wires over. We'll go ahead and feed in our green wire with our connectors on it up and over the bumper structures here, so that it stays up and away from the exhaust. Now that we've got it over here to the passenger side, we'll go ahead and feed it up, come out where the taillight assembly goes. Go ahead and pull our green wires on up. Go ahead and un-tape our pull wire. We can go ahead and connect the one end here with our taillight. Go ahead then and connect the other half to the factory wiring harness. We can then go ahead and plug the other half of the factory wiring harness. Go ahead and plug the smaller plug back in. We're going to go ahead and take a zip tie to help secure up some of these excess wiring here. Go ahead and trim off our excess zip tie. Now, we can put our light back into position, and put our push fasteners back in. Next, we're going to go ahead and take all of our excess four-flat wiring. Go ahead and feed it up into here. Go ahead and secure it off there. Go ahead and take a zip tie, and go up and back down through the holes here. We'll then go ahead and take all the extra four-flat wiring. Fold it up, and then we'll use a few zip ties to secure it to the backside of the hitch. Go ahead and trim off any excess zip tie. Next, we're going to go ahead and take our black wire here. This will need to be routed up to the battery and connected to the positive side of the battery at the front of our vehicle. We've gone ahead and routed our black wire up and over our bumper structure. Then, we added in some quarter-inch wire loom as it runs along here, part number 7509-10. It comes up, it goes over. We've also used several zip ties along the way to help secure it. The wire then drops down on this side of the gas tank, then comes out up in through here where we tied it in with some of the other lines. Continues to run up, following these lines, and then it's pulled upward, up into the engine compartment. We've gone ahead and used our pull wire to help fish the wire up into the engine compartment. We'll be using this positive connection point right here. We'll be tying our black wire into it. Before we do that though, we're going to need to install our inline fuse. Next, we're going to need to go ahead and trim our black wire to length. Go ahead and cut it down some. Go ahead and strip some wire back. We'll then go ahead and take our fuse holder. Go ahead and cut that in half. Go ahead and strip back both ends of that wire as well. On the one end, we'll be attaching a ring terminal. Go ahead and crimp it down. On the other half, we'll be using one of the butt connectors. Go ahead and put that in. Crimp it down. We'll then go ahead and connect the other half to our black wire here. We'll then go ahead and add some electrical tape. Next, we'll be tying in with this 12-volt location right here, so we'll need to take that nut loose. I will go ahead and remove the nut, and then we'll add in our ring terminal. Then, we'll put the nut back in place. Go ahead and put our cover back in place, then we'll need to add in our 15-amp fuse to our fuse holder. Take our cover off of that, and we'll slide the fuse down into place. Put our cover back on. Go ahead and add at least another zip tie here to help secure the wiring. Go ahead and trim off any excess zip tie. I will go ahead and test our four-flat wiring. We'll go ahead and connect our ground here on our test light to the open prong, and we'll have someone turn on the running lights. Go ahead and touch the brown wire. Our left turn, we'll touch the yellow wire. Now we'll do our right turn, so we'll touch the green wire. Now, for brakes. Now for brakes, we'll touch either the green or the yellow wire. As you can see here, everything is working just fine. Go ahead and put our dust cover back on to our four-flat. That will do it for our installation of the Tow Ready T-One Vehicle Wiring Harness, part number 118536 on our 2013 Dodge Journey. .
