Hello I have a 1962 galaxie 500 4 door.  My wiring was a mess after a bunch of long stories.  Any way I am trying to fix and have the wiring diagram. Though a couple wires don't seem to have homes . I have a red wire with factory ring terimial  on it so it's stock.  It was wired to a circuit 20 amp breaker  with a black wire not stock on the other post of it. I don't know where they went cause I just cut out any wire that wasn't stock. with the wiring diagram didn't think I needed them. So I have most of it wired with a three switch and button start system no key.  But I don't know where the red wire goes and not wanting to rip more wiring harnesses apart any one know where. The wiring diagram has on red wire from heat L on heater switch to heater resistor that s it.
