WICruiser, Attached is my crude diagram of how I addressed the dome light on my “48”….like you I couldn’t leave well-enough alone. I was going to just PM you with my schematic and avoid all the dissecting and drama that the group might otherwise inflict, but what the heck. I must advise that I built my own harness from parts and pieces of mostly GM 80ish vehicles and used a 1980ish GM headlight switch along with following a 1980ish GM Shop Manual. I put a 6-1-13 date on the diagram….so excuse me if I’m unable to clearly field any questions you might have. Good Luck, Dave
