wiring for the ecm on a '91

Post by raser13 »

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.


i love it when a plan comes together

Sorry for the quality, they're old

Doh!  They're from a Cavalier, but I think they're the same.  If you find that anything isn't matching up, I'll get some pictures taken of my '91 Beretta manual.  No time ATM.
