Need help, i got a ex cluster for my cx but the oil light doesn't work.I checked the circuit on the back and (i don't know how the guy that had it before me did this) the little copper parts that touch the metal prongs on the base of the bulb holder was ripped off. so there is no way to fix it. but i thought why not just find the wire that lights it up and connect it straight to the bulb. But i have no idea which wire it is and that is where H-T comes in . thanks in advance
