anyone have the pin outs for a '91 with a 3.1L or wiring scematic i'm currently trying to track a ghost problem with the digi guage cluster.the tach has problem reading sometimes and i know it's not the ald line so it's before the brain but i don't know where the singnal enters the ecm and would apreciate any info. p.s. also the alt. signal disapears as well but the coolant stays constant.
