I can't find a diagram of the headlight switch anywhere. I'd like to test the switch on the pins to verify it's bad before getting a new one. The blue/red wire connection point has no continuity in any switch position from the 12v input pins. This powers the instrument cluster, which is out in parking light. Someone spliced the instrument cluster wire into the headlight circuit which is why it only works when headlights are on and not the parking lights.
My check engine light bulb works which is from 93 2.3L, took it out and tested it. The EEC is an 87/88 5.0 transplant. I did the wire jumper to get the light to blink, it didn't blink. I can't get a single warning light to work, not even the e brake light. Is something missing that controls the warning lights or is the EEC just not compatible with the 93 instrument cluster? Or something else I can do to see if they work?
