Good photos showing wire size/color and where it goes in the connector would help also.1972 Chevy El Camino Wiring Diagrams: A Comprehensive Guide to Automotive Electrical Systems Building and restoring classic cars has become a popular hobby. What I have noticed is the wiring diagrams I have found so far do not 100% match my forward lamp harness or engine harness in my 1971 Monte Carlo.
