I just bought a 1990 782? 780 Bertone turbo, dirt cheap. The car is in great shape, but it doesn't run, there are a lot of cut and spliced wires. No blink codes coming up. I am beginning to go through a simple troubleshooting, as I can't seem to find any workshop manuals or any wiring diagrams. Where are the 780 guys and where can I get a workshop manual/wiring diagrams for this thing?

And yes, I looked on the internet, I'm finding a bunch of scattered files, but I want a hard copy manual, like a Bentley or a Haines, at least an online copy.

Wish me luck.

did you look at volvotips.com?

I did run by that site, a bunch of scattered links, not quite what I'm looking for. I want an A-Z manual. If it's possible. Or if it's similar enough to get one for a 940/740?
