I dont see any wiring in the pics, and he says "with a partial wiring harness, most of the odds and ends as well" Does not sound like it is complete.
Unless you get the stuff real cheap, I would look for somone selling a complete system, that is still intact. And by that I mean all the wiring and vacume lines have not been removed from the manifolds. Trouble shooting an EFI system is not somthing I enjoy, and not to many do.
