How to Install a Wiring Harness for a Trailer on a 2006 Dodge Durango

Today on this 2006 Dodge Durango we are going to install part number 118390 from Tow Ready. This is our wiring harness this is the modulite. First thing we need to do is get inside the vehicle and we will take off the tail lights by taking out these two plastic rivets. There are little pins going towards the body of the vehicle so you have got to rock it back and forth for it to come lose. And to completely take off the tail light you undo this connection right here and push this red button up. All right we will go ahead and do the same thing on the passenger side. Next what we are going to do is take our wire harness and we are going to the 4-pole in down behind the bumper towards the ground for now. Our lead with the red, yellow, and brown wires we are going to hook up to the wiring harness that was going to the tail light. Do not forget to push your red lock back into place. We are just going to leave that there for now. 00:55

Next we will take our white and green wire and do the same thing like you did with the 4-pole wire it behind the bumper and out of the way and your extra wire too. And our lead for our power going through our battery we will just push down below also. Next we will go ahead and route our wires to the center of the vehicle and across. We will start with the 4-pole and come back over the frame our module box through too along with the green and white wire and our red wire. We are going to attach our module to the back side of this bumper structure right here. It will be a good idea to clean this off first before you adhere it and then back it up with a zip tie just to make sure. We are going to leave our 4-pole be for now and we will go ahead and run our green and white wire across.01:44

All right next we will go ahead and bundle up our 4-pole wire and just for now we will tie it off to the hitch. And basically we are going to hook to the same zip tie that we made earlier, we will use that to our advantage and we will go make a criss cross pattern over it, that will hold everything tight together. All right we will go ahead and run our wire harness back up behind the tail light and we will go ahead and make our connection to the wire harness, lock there. Now we will just draw the rest of our wiring. It does not have to be tight or anything it just enough to keep everything out of the way. We will bundle it up and we can go ahead and start putting the tail lights back on. And all you have to do is get back underneath the vehicle and run our battery feed up to the front. We will go ahead and start hooking up to our 12 volt lead and then put some electric tape around it for safe keeping we will run this all the way across the bumper too and then go towards the front of the vehicle. Basically the main thing you want to do is stay away from anything that is hot or moving. 03:12

Here at the compartment, just shove the wires up as far as you can and we will pull it down from the top. While we are down here we will go ahead and zip tie off the wires to keep them out of trouble. You pull your wire out in the engine department out from the engine department and make sure you do not hit anything hot like your exhaust or any other moving components and what we are going to do is just come up from the back side of the battery here and just tuck it in behind here and then we will just leave that alone for now we will just go ahead and disconnect our ground leads so we do not shock ourselves when we start playing with these positive lead. Okay we will go ahead and install our fuse harness here. It is looped so we will just go ahead and cut it in half. You can keep these short or keep them the same length however you want but we are just going to go ahead and strip the wires and just crimp on the connections. We will just tuck away our excess so that when we take the battery off you do not have to worry about such a short lead. Thread this through. Pop that back together and then we can put our negative feed on. Okay and then we will go ahead and install our fuse into the fuse holder. Okay and all that remains now is go ahead and test the 4-pole out with the light tester to make sure all of your circuits work. And that finishes our install part number 118390 from Tow Ready.
