Interesting, thanks for the info. Since this programmer was working when I got the car, I suppose somebody else already did the work to bridge the compatibility gap. Any pointers on where I might look for said relay? I'd hate to rebuild the box, only to find out it's the doodad intercepting and corner-turning the signals that is responsible for breaking my HVAC.
