Ok well i'm always seein people tell everyone to run the codes! so i went and bought an OBD1 scanner so i can do this (same one as jrichker? has pics of), but it doesn't work. i justj got 000 reading when i try to test. i think someone before me may have moved one of the wires on the connecting harness? this is what it looks like. hope u can see where the yellow arrow is, that there is a wire broken off insided. this is where one of the prongs on the scanner plugs in. beside it, the blue arrow, the scanner doesn't plug into, so i'm thinking maybe someone just moved it over? is this possible?anyone know what might be wrong?
