I'm putting the dash back in my 93 sol si, and in the cluster harness there is a lonely black write with silver spots on it, just like every other ground on the car.only trouble is,i can't recall for the life of me where it plugs up at.it is just a female spade terminal with a plastic cover, and it dumps from the harness almost in the center of where the cluster would be.any thoughts?
