I have converted my car for neg ground with a 1 wire alt. I'm also using an electronic ignition that is set up for neg ground systems. Wondering about the black wire to my coil from block 8 in the rear rail connector. It originally went to the - side of the coil. Should this now go on the + side? I've had the fuel gauge rewire done and bilge pump wires reversed. Wipers seem to park OK but time will tell if I want to change that. Engine hasn't been started yet but I've tested systems with the battery hooked up and so far so good.
