    Unhappy Someone / anyone please help. Pin outs l4big ecm

    I am hoping someone can help, im looking for pin outs for l4big ecm from s10. im trying to make a bench harness and the p01 / p59 must have different pin outs because that bench harness is not working for those at all. I have looked in all over and maybe im looking in wrong place, might even be posting in wrong place. just no luck. any help would help please.
    thanks

    I have an old offline version from back when GM used to mail out physical CDs to dealers. Since 2009 it has been web-based-only.
