1971 Dodge Dart Swinger Turn Signals and Reverse Lamps

Hi, I am working on a 1971 Dodge Dart Swinger we recently got running and am having issues with the turn signals and reverse lamps. According to the schematic I have pulled from MyMopar the wiring changed from the 70 in which I own, and it appears that the black wire to the turn signal flasher is fed from the neutral safety switch while on my 70 it is fed directly from the fuse panel. Is this correct or is it a misprint? If it is correct, does the neutral safety switch jump power from the starter relay to that circuit? Whether or not it is worth noting, the gas gauge and temp gauge also do not work on the cluster, which could also line up with the ‘70 feeding the voltage limiter. I have replaced the voltage limiter on the dash and that was not the fix, and I can’t seem to get up there with a test light to test for power. Thanks!
