Gauge Illumination question
Hi all-- thanks to this thread I have a nice vacuum gauge working. ( Various problems with fittings and when I first tried the gauge, it read about 11. I deduced that the hissing noise at the gauge fitting might have something to do with it.)
Anyway, now I need to wire up the bulb. I thought it would make most sense to wire it into the instrument panel so I could get the dimmer working. But how do know which wire is the wire for illumination? I have spent many hours searching the web for wiring diagrams or info like, "dash illumination is ALWAYS the yellow/white wire". So, I'm stumped. Here's a picture of the dashboard wiring harness). Anyone have any suggestions or an easier way to do this? Many thanks in advance.
