Lights for aftermarket gauges

I put aftermarket gauges in my 72 pickup. Kept the speedometer & Gas gauge.
I have a 3 hole gauge panel. Trying to figure out How or where to hook up to the dash lights. I guess I could go off the headlight switch But don't know what wire (color). Looking for suggestion.

Re: Lights for aftermarket gauges

Factory is normally a grey wire. You should see it at the fuse box.

Re: Lights for aftermarket gauges

I hooked mine into the gray wires where the heater panel light connects to the harness.
