In this video we're going to replace the trailer harness connector on this 2002 GMC Sierra 2500HD. This is the same as most GM trucks and SUVs. The only tools you'll need, probably, are a screwdriver and maybe some penetrating oil.

If you're having trouble with your trailer lights, a lot of time, what it is, is this receptacle can get corroded. Moisture gets in here, and corrodes the contacts. It's actually pretty easy to replace.

You want to disconnect the back here just by pressing on this tab here and working it off. Now, you want to use your screwdriver and there's a little tab right here that you want to push in on and then turn it counterclockwise. It comes out.

You'll see, here's the new one from 1A Auto. That'll go in. I actually used some penetrating oil and sprayed it around, just to make it easier to install it, here. Let's see here. With this hand I'm kind of twisting it clockwise and I'm going to hit it in to get it going. It fits in there nice and tight. Then, just plug in the back here. You're all set to go.

We hope this video helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll-free, 888-844-3393. We're the company that's here for you on the Internet and in person.
