You could easily have it done in a week. CIS really doesn't need that much wiring at all, just need your 12VDC and your switched power to the ECU stuff. 98% of the engine running harness and circuit is all in the engine bay or rain tray. It really is that simple, just get the fusebox junk cleaned up and she will be running in no time.
He's got a CIS Motronic harness and computer out of a passat with the 2.0 16v. There's a couple more wires, but generally they're not too bad to hook up. The biggest pain about it is deleting stuff that isn't needed. His big problem is the PO (sort of) converted half of the dash wiring into CE2 and left the other half connected to the original fuse box. It's almost impossible to figure out what to tie into, or what you're tieing into.
Greg does have that rabbit on the side of his garage he's suggested using as a LeMons race car. I'm sure you could convince him to part with the dash wiring and possibly any interior parts you might need.
