Running Lights Not Working
 

I just replace the stock radio with an aftermarket one in my 1988 supra and I had everything working then i realized that when I turn on the headlights only the headlights turn on, the running lights and the dash lights weren't working. The brake lights and blinkers still work and there are no blown fuses. If any one has an idea what I did wrong I would like to hear it.

Thanks

Possibly just coincidence that you noticed it just after the new stereo, I've heard of headlamp stalks failing & doing stuff like that too so possibly the problem's in the switch?

I guess the switch is a possibility but I was looking at the wiring diagram and noticed that there is a radio illumination wire that I don't remember connecting to anything. So I might mess around with that before I decide its the switch because it was working before I replaced the radio.
