Conversion wiring
I dont think I'd give away the whole harness...I dont think it will plug onto a 66 anyway, and the senders and ign. stuff is longer on a /6, so you can just shorten the leads and run them on the V8. Like BJR said, all the modules will work with any engine, but the rest of the stuff will need to be modified. Of course, you could just buy the V8 engine harness, and a new headlight/front end harness..That has the voltage regulator, module, resistor, and stuff on it IIRC, and that's what he's asking for
