Installation of a Wiring Harness for a Trailer on a 2007 Chrysler Pacifica


Today we are going to be installing wiring harness part number 118303 on a 2007 Chrysler Pacifica. Okay, we are at the rear of the vehicle, and we are going to go ahead and locate the attaching points for our wiring harness. The attaching points are actually located directly behind the tail lights. So the first thing we need to do is go ahead and remove both of those. To do that, we just need to remove the two screws here on the inboard side, and then we will just pull the tail light assembly away.

Okay, and with the tail light assembly removed, you can see right here, this is the connection point where we are going to be plugging our T-harness in line. So you want to go ahead and disconnect these two. First you need to take this red push tab, slide it over, and pull the two pieces apart. Then we are going to take our wiring harness and we are going to start by feeding the connector here, with the green and white wires - we are actually going to drop that down into the hole in between the bumper and the body of the vehicle. And that is actually going to be routed over to the passenger's side. And we are also going to feed the 4-pole down through the same opening. And that is going to leave our Modulite box, our power wire, and our set of connectors with the yellow and red and brown wires over here on the driver's side. We want to go ahead and connect the T-connect portion into the vehicle harness. And we definitely want to make sure we relock the locking tab. We want to mount the Modulite box here on the back side of the body panel. And you can see there is double-sided tape here. I am just going to clean off a little bit of the area, pull away the sticker, and attach it right there. We want to go ahead and pull the grommet out that our wires are coming through. And, if you see, if we pull that back just a little bit - there is another wire here that is taped to this wiring harness, just inside there. That is actually our connector that we are going to be connecting our power wire to. As you can see, there is foam tape that is holding that in place there. I am just going to remove some of the foam tape here, and then go ahead and make our connection. Since this wiring is going to be coming out in this area, we want to make a little slice here in the grommet so that the wire can easily come through. You want to make sure that your fuse is in your fuse holder. And then we can go ahead and reattach our tail light assembly.

Okay, now we want to go down under the bumper, where we had dropped our wires for the passenger's side and the 4-pole as well, and we are going to route it across to the passenger's side tail light assembly. In order to try to avoid the exhaust as much as possible, what I am going to do is actually run a piece of light-gauge wire from the inboard side and just feed it through, over to where the wires are at now. And I just pull that down there. What I am going to do is just go ahead and tape my T-connector here to it. And this is just going to help me fish it through that tight space there. And I am going to attach my 4-pole to it as well. We want to make sure we pull through all the remaining slack And, again, I am just going to tie off the 4-pole here at the trailer hitch. We can tie up our excess wire later. We are going to continue on. And, again, I am going to feed the T-connector through the opening in between the bottom of the bumper and the body over here on the passenger's side over the exhaust. And now that I have got the connector routed in between the bumper and the body, I am going to go ahead and feed it up through the opening in the body, up to the tail light assembly on the passenger's side. And we are just going to go ahead and make our connections like we did on the driver's side. All right, and now we are going to back under the bumper area and secure all the loose wires that we have left over.

Lastly, on model years 2004 through 2006 we need to put the 20-amp fuse in, in the fuse block under the hood. It is in position Number 10, and it is labeled "Trailer Tow/Spare." On the 2007 models, it is already equipped. And this will conclude the installation of wiring harness part number 118303 on a 2007 Chrysler Pacifica.

Trailer Wiring Harness Installation - 2008 Chrysler Pacifica

Today on our 2008 Chrysler Pacifica we'll be installing the Tow-ready T-One Vehicle Wiring Harness with 4-Pole Flat Connector, part number 118303.To begin our install, we'll first need to remove the rear taillights. To do this, we'll open up the rear hatch and then remove the 2 screws securing the taillight assembly. Starting on the driver's side, after we remove the screws, we'll set them aside. Using a plastic pry tool or flat-blade screwdriver, gently pry out between the housing and taillight assembly, pulling straight back from the vehicle, to release the fastener underneath, careful not to break this fastener.Next we'll remove the taillightcompletely by unlocking the red locking tab and then pressing on the connector lock, releasing the wiring harness from the taillight assembly. Now that we've removed the driver's side taillight assembly, we'll go ahead and repeat the same process on the passenger side. We'll remove the manufacturer's grommet, where the wiring runs into the body of the vehicle. After we remove the grommet from its position, take the yellow wire, pull it out along with the connector that's wrapped in the foam padding.

Today on this 2005 Chrysler Pacifica, we're going to be installing wiring harness part 118303. Wer'e going to first go ahead and locate the ports that were going to be plugging our wiring harness into. Now these ports are located directly behind the tail lights on both sides of the vehicle, so we're going to go ahead and remove each one of the tail lights. To do that you can see we have opened up our cargo door here to access the fasteners here on the inboard side, just go ahead and remove those and we can pop the tail light right off. If you turn the tail light over here, right here at the bottom is the connector we're going to be using, you want to go ahead and separate the two pieces first. To do that we want to go ahead and slide the red locking tab over first and then go ahead and press the release button here at the top and pull the two pieces apart. We can set the tail light off to the side for the time being and go ahead and do that for the passenger side as well. We are going to continue over here on the drivers side, and pull the grommet away from the vehicle. This wiring harness is actually a powered unit and when we pull the grommet away we actually have an existing power wire that were going to use. If you follow the tape forward here you can see there is a red wire here that is taped off and if you cut that back, there is a connector on there and we're going to go ahead and use that.
