Hello forum. Trying to figure out what to check to get parking lights working. I've tried 4 new headlight switches. The lights will come on at one spot on the switch just after the detent between running to headlights. You go further then the running lights go out and the headlights come on and running lights go out. There's no spot that both headlights and running lights are on. At this one spot, all the lights work correctly so that kinda proves that the lights all work, etc. However, having 4 bad switches also seems unlikely. Headlights/fog lights/turn signals all work normally.

Some additional info:
I just re-did the interior and pulled the dash to replace heater core. Also put in LED instrument bulbs. The guages/lights all work so those connections are good. It would seem that I did something while moving the dash but I do not recall any lighting harness connectors being disconnected. Looking under the dash hasnt produced anything obvious. All the steering column connectors are plugged in. Horn, wipers, etc, all work.

Does anyone have a pin-out diagram of the light switch to check continuity between the pins depending on the switch setting. All 4 of the switches I have appear to be the same. Is there a diagram that's out there that would show what wires I could jumper together on the headlight switch connector to prove the wiring is working?

Thanks for any ideas, Guy

Thanks, knowing that tan/white wire was supposed to be hot was the trick. The 15a fuse in that circuit was bad (not burnt out) must of cracked from vibration. All good now.
