hey guys, a few more problems with the 89 rs here... i checked all the fuses they're good, but my dome light is still out, brand new bulb and everything, what is going on? and also where is the temp guage wire located under the dash what color / which one is it (so i dont have to tear it apart) it was converted to a carb, but now i need my temp guage working, thanks! the dome light is really confusing me tho..

 

The temp wire should be green. You will see it in the plug behind the cluster or in the wad of spagetti under the dash.
Did you check the dome light with both doors and the switch? None of those work? Are the under dash floor lights on? Maybe your door jamb switches are not grounding. Check at the light for power. It should have power all the time. The door jamb switches and head light switch make the ground to complete the circuit.
