For starters, this is likely a problem I created
I installed a stereo, and when I went to drive the car tonight I had no dash lights.
For full time power to the stereo I tapped into a hot wire running to the clock (It is green with a red stripe.)
No fuses are blown, everything else works except the instrument lights.
I replaced the headlight switch about a year ago and have not driven it that much, just cruising and mostly during the day.
I undid all the stereo wiring and it is still the same, no instrument lights (it is set up with two plugs, the other was a two pole plug that I used for ground and switched power after checking it with a meter.
If anyone has any ideas I'd like to hear them before I take the dash back apart.
