Hi. New to FBBO. Working in a 68 Charger RT. It's a bad bad mess. Electrically destroyed by people in the past. New painless harness and OER complete gauge set, but!?. Having trouble le with the tic toc tach. There is no info on hook ups. Any one delt with this? Classic Industries has no answers and so far OER not responding either. The clock/tac has a hole on back to install the factory back light. There is a 4 inch gray wire coming out the side with a spade terminal. 2 stud terminal mounts on the back of gauge. 1 is marked +, must be B+, 2nd is marked with S. I do not know what the gray wire or the S terminal is for. It's a $400 gauge and don't want to mess up anything. Bought the entire new gauge set from Classic Industries, plus cicuite board and regulator, plus all new bulbs and adding a ground from cluster to dash frame to be sure. Any one know propper hook up for this gauge?? Working in industry since 1986 & with Chrysler Dealer currently. Thank you for any help.
