Ever since I’ve had the car for about 9 years, everything other than my speedometer doesn’t seem to work. I found wiring diagrams but can’t really follow them and don’t know where I’m supposed to have power and where I’m supposed to have ground. Was wondering if you guys could help me out. I seem to have dash lights and signal lights but nothing else. I know from the wiring diagram that all my pins are in the right locations to the back of the gauge cluster.
