I got a 1978 GMC 350 4X4 truck and needing some help with cut wiring. Coming out of the fuse box through the cowl panel. Wiring cluster under the hood that mounts to the fuse box. It goes to the engine and lights. Anyone have a schematic that shows or explains what wires goes where? Thank you for any help.
