So I ditched all the BS going to the relay and ran the small pink ignition hot straight to the switch like the schematic above and everything appears to work as it should. Not sure what the previous owner had going on.
Connectors are from my trial and error experiments
Mine had a steel bodied relay that looked factory. First square so not too experienced. After looking at this schematic I do notice something different in the wiring. I may try tonight to copy this. Hopefully it’s right for a 73 suburban
