I have a 2003 Toyota celica gt and about a month ago had a new radio installed, yesterday when I got in to drive it my dash light, tach, speedometer, and gas gauge weren't working, my car is a 5 speed so when I park it I usually put it in neutral and pull the e-break, during the day my lights are now all working fine, but at night when my head lights are on I loose all my dash lights? I have herd it is a tail light relay could of gone bad but I can't find it! I have looked everywhere for a diagram and can't find one! Does anyone know where it is located? Thanks!!!
