ive completed a 2.4l to 3400 swap and i just realized the harness pinout is different between 1997 pontiac, buick, oldsmobile, and chevrolet cars even though the computers are the same. i urgently need the harness diagrams for a 1997 grand am, buick century, and chevy lumina. trying to get my project running today. this is what is holding me back. please!
