I had wired up the headlight switch quite a while ago on my 69 Camaro and now it had stopped working. I took it out of the dash assembly so I can run a test light on it and I noticed that only 1 wire is hot coming in (red). I see from the Painless wiring charts that the orange wire should also be hot. For some reason it's not though. Anyone know if both wires need to be hot to run the switch? Can;'t figure out why it has cut out all of a sudden.
