Trying to resolve NSS issues on my 1970 Dodge Challenger. I have a brand new NSS, three prong. I also purchased a new pigtail just to ensure good connection. The middle brown/yellow wire goes to connection "G" on the starter relay like its supposed to. The black and black/white follow their path correctly as well. If i short out the black and black/white at the plug connection, the reverse light comes on. I checked continuity across the two outside pins of the brand new NSS in all gears and its open in all gears. I would expect continuity in reverse as it is actuated to close the loop for reverse lights. Car will not start in any gear. If I add a cable from the "G" point on the starter relay to the negative terminal of the battery like the previous owner had, the car will start in any gear and there is still no reverse lights in any gear. I am out of ideas shy of assuming i got a bad NSS. Any help is greatly appreciated.
