GM Style Headlight Switch 

Me too.

ML btw

Maybe you've figured it out since you posted the comment, but I'll reply anyway in case it helps others. There's a grounding wire with an attached washer (basically a giant wide ring terminal) that is pinched between the headlight switch and the plastic dash (ring terminal goes in front of the headlight switch body around where the knob would be inserted), it grounds the headlight switch body to a reliable chassis ground of the car. I don't know the name of the part but you could fashion your own ground between the headlight switch body to a chassis ground. The headlight switch also gets a ground on the male spade connector that's in the white ceramic, typically not numbered on the 7- or 8-pin headlight switch, but this is for the dome light. I was digging around in my 1972 Chevelle and found this wire sitting loose behind the dash and reconnected it.

@@TVOmp3 Thanks for the high quality answer! We rigged up our own dedicated ground wire to the metal body of the switch, much as you described.

​@TVOmp3 have a coupke question for you plz.. have 2 wierrd things happening. My high beams stay on with the low beams somtimes after I set up relays for my headlights.. but I know I wired them right..and then the headlights started comming on in the parking postion... I'm lost at what's going on its such a simple circut lol

its based on resistance in the wire looking spring from compression and expansion.

I need that same thing too.
