How to Install a Wiring Harness for a Trailer on a 2007 Chevy Silverado

The 2007 Silverado body style as well as the 2008 styles have a place on the bumper where the plug can be mounted. We remove the cover here to give us the hole to mount the plug into place. Once we've removed the knockout from the bumper area we'll place the harness into position. We're going to have to drill holes out to mount this into place. You can use either a pen to mark the holes or a punch tool which is what I'm going to use. Now we can move onto the drilling. Once we get the holes drilled, we want to mount the connector into place with the existing fasteners. Once we have the fasteners in we want to secure them with the nuts on the back side and tighten them down. Once we've mounted the plug onto the bumper area, we just need to make the connection up underneath the vehicle here. This is the back end of the connector we just installed, and this is the other side of the factory 7 pin connector. You just want to plug these together. This concludes the installation of wiring harness part # 30955 on a 2007 Chevy Silverado.
