the lights on my gages are out on 1990 Pontiac Bonneville

i was installing a stereo in my car and connected the wrong wire and shot out the lights on the gages, and i already checked all the light bulbs on the back of the gages

your illumination fuse is blown replace that and u should be good to go , it should be labeled ilm on the fuse panel cover if not just check fuses and replace the bad one and it should fix your problem
