How to Install a Trailer Wiring Harness on a 2007 Pontiac Torrent

Today on this 2007 Pontiac Torrent we are going to be installing wiring harness part number 118432. We are in the rear cargo area of our Torrent and we want to locate the port that we are going to be plugging our wiring harness into. This port is located actually in our jack storage compartment connected to the bottom floor board. The first thing we need to do is get inside here and remove our jack. With that removed if you look down at the bottom of the floor board you will see an open ended port which we are going to be plugging our wiring harness into. 00:38

If you take a look to the forward side of the plug you can see that there is a ground stud. We are going to be utilizing that ground stud to ground our wire on our wiring harness. If you look at our wiring harness here you can see we have got a separate white wire with a ring terminal on it and that is what we are going to be adding to the ground stud. 00:53

At this point I am going to take the nut off the ground stud underneath at the bottom and plug the harness into the port. With the ground wire attached I will put the nut that goes on the mounting stud back into place. With the harness installed when not in use you can leave it in the storage compartment, the jack storage compartment. When you want to go and use it just take and pull it out the cargo door of the vehicle. You do not have to worry about closing the cargo door on it, the weather stripping will prevent it from getting pinched. 01:23

From here we can put the jack into position. One final thing that we need to do is we need to take the provided fuses and relays and plug those into position in the fuse block underneath the hood. With these relays and fuses in place our tow package will now be active. Now we are up under the hood and if we look over on the driver side of the vehicle nearest the firewall. Here is our accessory fuse block that we are going to be plugging our fuses and relays into. I am going to take and remove the lid and if you take a look at the back side of the lid, all of our positions are labeled. 02:06

We are going to start by plugging the relays into place. We will start with the relays and we will be plugging those into position number 58 and 59. Then we will follow up with three ten amp fuses and we need to put those into positions 35, 37, and 43. When plugging the relay into place we want to make sure that the sloped edge of the relay is facing toward the driver side of the vehicle. This will ensure that the relay is going to activate properly. With the relays and the fuses into place our tow package is now active and our installation is complete. That will conclude the installation of wiring harness part number 118432 on a 2007 Pontiac Torrent.
