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. If there is a plug on the end of the wiring harness located above the spare tire, it will simply plug into the rear of the HM40975. If the harness ends in bare wires, you will need # PK11998. The pigtail would plug into the rear of the HM40975 and wire up to the existing harness.

I have a 2004 Silverado 1500 Z71 with factory install tow package that has a 7 PIN trailer connector already installed. Will the HM40975 bracket be a bolt to bolt swap or will have drill new holes in my bumper for it?
