How to Wire a Chevy Trailer Plug
Wiring a Chevy trailer plug involves connecting the seven wires of the plug to the corresponding wires on the truck’s electrical system. Here are the steps to follow:
- Start by gathering the necessary tools, such as a wire cutter/stripper, electrical tape, and a volt meter.
- Locate the truck’s electrical socket and remove the cover if it has one.
- Identify the seven wires on the truck’s socket and match them with the colors on the trailer plug diagram.
- Use the wire cutter/stripper to strip about 1/2 inch of insulation from each wire on both the truck and trailer ends.
