This 28 circuit 1967-1972 GMC/Chevy harness was designed to fit the trucks, Blazers, and Suburbans. It features a factory style bulkhead connector and has many of the factory connectors already installed on the harness out of the box. Including: the headlight connectors & switch, dimmer switch, wiper motor, ignition switch, blower motor & switch, blower resistor, and instrument cluster. Each wire is custom printed with the circuit identification as well as using GM color codes for easy installation.
I purchased this to replace the wiring in my 71 chevy as well as provide a base to include fuel injection and other items that weren't around that long ago. The fuseblock includes all the connectors for the stock items on the truck with only a couple exceptions like the brake light switch connector for which i simply used the connector on my existing harness. The more difficult part is selecting wires for items not setup for use in the fuseblock already like fuel injection and any other accessories like electric lockers, cb, etc. I like it and would buy it again but would like a more detailed wiring diagram in the instructions to aid in customizing the harness for other accessories.
