How to Install a Trailer Wiring Harness on a 2005 Pontiac Vibe

Today on our 2005 Pontiac Vibe well be installing the Tow Ready T1 connector, part number 118458. First, well open up the rear cargo door, and then well need to open up the rear cargo tray spare tire area. With the tray cover up and out of the way, well go ahead and remove the spare tire tool tray. Well remove the center fastener and then we can just simply lift it up and set it out of the vehicle for reinstallation later. Next well go over to the access panel behind the drivers side taillight assembly. Removing the access door well expose the wiring to the rear taillight assembly.

Now we can go ahead and repeat the same process on the passengers side. Here on the drivers side well then go ahead and remove the connector for the brake and taillight socket. Well press on the locking tab and remove the white connector from the socket. Then we can take the red wire from our new Tow Ready converter box and plug in line with the manufacturers wiring and the other end into the back of the taillight socket. Next well go ahead and repeat the same process with the turn signal circuit here on the drivers side.

This will be the grey connector. Well plug it in line with the yellow wire from our converter box, again plugging into the manufacturers wire and then back into the taillight socket. Next well take the white wire with the pre-attached ring terminal from our converter box and secure it as a ground here behind the taillight assembly. Using a self-tabbing screw provided with our install kit well go ahead and complete this procedure now. Next well go ahead and take the four pole and green wire connector and feed them down behind the interior trim panel, reaching through the body cavity and pulling them out into the spare tire well area.

Next well go ahead and take the green wire connector and continue on over to the passengers side, where well remove the grey plug from the socket and plug in line just as we did on the drivers side with the yellow wire. Now with all our connections made well go ahead and use the black zip ties provided with our install kit to secure our wiring, and then well cut off the excess from the zip ties to clean up our install look. Next, well go ahead and reinstall the spare tire tool cargo tray, feeding the four pole connector up into one of the trays. Then we can go ahead and complete reinstalling the rest of the interior trim panels. This will complete our install with our new four pole connector.

Now well go ahead and show you how to use it. Simply unlock the cargo cover, open it up and pull the four pole out and down to your hitch or accessory. Be careful to stay away from the latch as pinching the wire off in the latch can harm the wire, however the weather stripping is thick enough that it wont and will simply close the rear cargo door on it. Then, once were finished using our new four pole connector well simply roll it back up and store it in the spare tire tool cargo tray. That does it for our install of the Tow Ready T1 connector, part number 118458 on our 2005 Pontiac Vibe.
