hi all i just bought an 02 wrx the person before me has put in three gauges where the clock normally is, ext temp, oil pressure, fuel pressure. they are greddy gauges thats all i know. a few questions
1 the back lights dont light up on the oil pressure and fuel pressure, is there a way to replace just the light or do i have to buy a whole new gauge? or could it be a wiring problem and where would i start checking?
2 the oil pressure gauge is not working, what are a few things i could start checking?
i havent even begun to look at the gauges sorry just looking for some ideas to get me started.
thanks in advance
