[ford38v8]

I was initially paranoid to rip out my harnesses, afraid I'd never get it running again. I bought all my harnesses as original from a reputable harness maker. I then reproduced the Ford wiring diagrams in a larger format, one copy for under the car and one for the wall. Proceeding with tape and markers, I disconnected each existing wire, marking each for location. Comparing the original to the repop, the Ford diagram, and the repop maniufacturer diagram, I rewired my car bumper to bumper. Now this was overkill, of course, but I wasn't going to make a stupid mistake. One last thing, my car is a '38 convertible coupe, so it has no turn signals, no overdrive kick-down, no trunk light, no overhead light, no rear speakers, and no other added foofara like yours might have, so yes, If i were you I'd do the overkill thing also. You'll be happy you did.
