It is getting soooo close. I probably could take the jack stands out and it would move under its own power (stopping might be rough, however, until I figure out the brake booster issue).

Fix brakes, shorten the overly long harnesses and it’s… ready?

Puzzling through the wiring of the swap and can’t figure out where the connections for the brake booster-related components go.
I could try wiring them manually based on the Bentley diagrams I have, but I think I’ll check first with the forums to see if anyone there has the answer.
Booster pump:

Vacuum vent valve plug on side of brake master. There’s still a wire connected to the fluid level sensor… why would the wire get pulled off the brake vacuum vent?


There doesn’t seem to be a matching part in the donor A6 and I can’t figure out where in the harness I would plug in the booster. So… it’s coming out.

Not only does it fire up, but it moves under its own power. Unfortunately it’s stuck in 2nd or 3rd gear until I get the A6 TCU to play nice with the A4.
