7-Way Wiring Harness Installation on a 2004 1500 Chevrolet Silverado

Expert Reply:

You can use the Pollak 7- and 4-Pole Trailer Connector Socket, item # HM40975, if you are replacing an existing 7-way connector on the rear of your 2004 Chevy Pickup. If you need to install the 7-Way connector for the first time the factory connection point is going to be on the left side of the vehicle above the spare tire.

You will need the OEM Style 7-Way and 4-Way Trailer Connectors for Ford and GM Trucks, item # V30607, or the Replacement Multi-Tow 7-Way and 4-Way Trailer Connectors for Ford, GM Trucks, item # 30955, to complete the wiring out to the vehicle bumper.

You just have to remove the cap on the factory connector and plug in the trailer connector.
