T-One Vehicle Wiring Harness with 4 Pole Trailer Connector

Video Transcript for Wiring Harness Installation - 2009 Chrysler Aspen

Today on this 2009 Chrysler Aspen we are going to install part number 118390 from Tow Ready. This is their modulite wiring harness. The first thing we need to do is open up the back hatch of the vehicle and get to the fasteners that hold the lights in place. We are going to remove the taillights as our first step. These just have plastic fasteners that you just remove. When you pull these off, you want to kind of pull them off to the side a little bit and pull back a little bit. We can go ahead and disconnect this light for now. Just push in this red tab right here and push down this button and it comes apart. We have our driver side off. Let us go ahead and do the same thing with the passenger side. Next we are going to take our wire harness and we are going to the 4-pole end down behind the bumper, towards the ground for now. And then the lead with the red, yellow and brown wires, we are going to hook up to the wiring harness that was going into the taillight. Next we will take our white and green wire and do the same thing like we did with the 4-pole wire. Drop it behind the bumper and out of our way. 1:01

Next we will go ahead and route our wires to the center of the vehicle and across. We will start with our 4-pole and come back over the frame and back towards the center. We are going to leave our 4-pole be for now. And we will go ahead and run our green and white wire across. Alright, we will go ahead and run our wire harness back up behind the taillight. And we will go ahead and make our connection to the wire harness. We will go ahead and zip-tie our extra wire. Alright, let us go ahead and plug the T-connector back into the taillight. Now let us take our fasteners and we will just push them back into place. One more thing to deal with on the driver side before we put it back together is deal with the red wire here. This wire is going to be hooked up to the black wire that comes with the kit and is going to be ran up to the battery. We used some electrical tape to seal everything up. And we will go ahead and take this black wire and run it down behind the bumper as well. 2:06

We can go ahead and mount the modulite. We are actually going to spray down part of the interior surface and we will use adhesive that comes with it to mount it in place. Now we can go ahead and bundle up any extra wires and go ahead and reinstall the taillight. We will go ahead and route our wire up to the front of the vehicle. Now basically what we are going to do is follow the frame rail going up and over the suspension and up to the engine compartment. Just make sure we stay away from anything moving such as the suspension components or anything hot like the exhaust. We are at the front of the vehicle now. We actually ran the wire inside the frame using a fish wire and we got all of the way through, which is pretty nice. Now what we are going to do is wrap around the bottom edge and come to the outside of the frame because, on the other side, it is pretty close to the exhaust. We will just wrap it around and we will go ahead and run our wire up into the engine compartment. 3:05

Alright, let us go ahead and reach in and pull the wire out. We have our wire pulled up and we are going to run it across. Now we need to tie it off somehow. What we are going to do is put a series of holes in the plastic right here just so we can zip-tie our wires safe and out of the way, over to the battery. Next we will go ahead and add the fuse holder to our lead. We are just going to cut it in half and add a ring terminal to one half and a butt connector to the other one. Go ahead and kind of judge how much lead we want left over. Cut off the excess. We will go ahead and connect up to the positive terminal. We will be using this nut right here. And we will just attach to that. That is connected. Let us go ahead and add our fuse to the holder. And once you are satisfied that everything is working, go ahead and tape it up and zip-tie any additional wires if necessary. And with that that will finish our install of part number 118390 from Tow Ready.
