ecm upgrade
I read the technical article and I understand the rpinning just fine. the part I am lost at is splicing. I am upgrading my 85 ecm to an 87. I have the new maf relays and ecm, but I don't understand where to splice the new relays in at. If anyone has done this before and can help me out thanx.
