Does anyone know of a source for a color wiring diagram for a 1978 Caballero ? I'm attempting to undo some electrical ****ery visited upon this truck by a tweeker "mechanic" before I bought it. :-( Specifically I'm repairing the main engine/under hood harness. I've found all kinds of B/W individual wiring diagrams but nothing showing a complete layout in color. I've unloomed it all and started tracing/repairing each wire but there several clipped and /or spliced wires that I need to identify to determine correct length/routing/bundling. Also a pin out diagram of the firewall connector would be helpful . TIA
