1971 GMC Wiring mystery
I hve a 1971 GMC V8 truck that has a strange harness on the engine and I cant find out what it goes to orwhat it it is for, can someone please shed some light on this mystery?
The harness plugs into a brown wire just above the fuse box inside the engine compartment, it has what looks like a horn relay and another relay attached to it, it travels across the firewall and has three different connectors on it. One looks like it goes to a oil pressure or temp switch, the other one looks like it is a alt plug w/3 wires into the two place plug, and the third plugged into the 350 turbo trans just behind the dipstick tube. I am confused as I have not been able to find this on any schematic.
