so I put a 91 si harness in my 89 hatch, but I must've used the dash harness on something else cause I can't find it anywhere. theres a plug hooked to the top of the fusebox, that has 18 pins on the si harness, and the dx harness has 12 pins. I've got a factory wagon service manual and wiring manual but it does'nt actually have any pinouts. how am I gonna figure out what the extra wires run? I thought the factory manuals woulda had that info. Would like to just repin the harness to work but no way to know what goes where. anyone got any pinouts on that stuff?
