Today were working on 2007 GMC Sierra. Were going to install the Pollack 7-Pole Connector part # pk11916. Before we remove the knockout here in the bumper I'm go ahead and get disconnect the current harness that's connected to the knockout behind the bumper. For the easy in installation of shooting this video we've going to have removed this bare tire and you see the connector goes into the knockout here. At the top side of the harness connector is a locking pin make sure you'd pressed it before trying to remove. You'll see here is a lock now we've it removed we go and take the knockout out of the bumper.
To remove the knockout out the bumper first we pressed them the locking tab and then rotate it to remove. Now were going to take our new 7-Pole Connector we'll put it in and lock it in place. Now with our new 7-Pole Connector in place we can re-connect their harness. Line up the locking tab then firmly press it into place double check it by giving a little thug and that can place your install of Pollack 7-Pole Connector part # pk11916.
