I've put the dash together again with all the wiring in place and a hole for the steering wheel buttons made.
The only thing I'm concerned about, both the cruise control master switch and the heated seat switch have slightly more dimmed backlighting than the ATC and stereo panel. I've yet to check the voltage but perhaps this is normal?
When I finally get it to work, I will amend Pete's excellent how-to with some pictures and explanations for future enthusiasts.
