    Nice work. Much easier with the engine out of the car. I think every single LS truck engine I've ever worked on has at least one broken exhaust manifold bolt.

    I'm heading to Everett early next month; I can stop by the Public Library, where they may still have wiring diagrams for mid-'80s GM cars, among other resources for them.

    I hate busted off exhaust manifold bolts. FORD FE engines are famous for that as well.
    Glad to see the steady progress. Thanks for the update.

    The FE's only saving grace is they're the top ones, which can be drilled out, if done right. Done my share of those peĀ¢kerheads. The replacement bolts get slathered with anti-sneeze.

    That would certainly be helpful. I often forget that libraries may have that kind of info. My local library is pretty small though.

    Since I was 90% sure I didn't need any of it, I removed the harness for the CPU completely. The harness on the other side I just plan to manually check what each wire does if I can't get a wiring diagram.

    Another idea--would you post the wagon's 8th VIN digit and the computer's 7-digit part number? I can hop on Chilton online, see if there's anything usable there, such as a pin voltage chart, which will have pin position and wire color code.

    I just had another thought, and I accessed Chilton online, just with year/make/model, and it's not much, but there might be enough to get started. 85846152.jpg 85846153.jpg 85846154.jpg

    Now, there are two engine diagrams, you'll need to choose the correct one. There aren't any pin voltage diagrams on here for your car, but at least you can find the car functions and power/ground wires you'll need for the LS harness. BTW, if I haven't already said it, I'm grooving on the Mustang in the background of your first posted pics! '68?

    That's amazing! Especially because they didn't bother to put that in the actual Chilton's manual I have for this car. It looks like it's missing significant parts of the wiring harness, but it's a lot more than I have now. Thanks!

    As for the Mustang, you mentioned it. :p There's a couple pics and info of it on my first thread about the Buick:

    With the way my memory is, I likely already commented but forgot.
