Thanks for that info Neil. I was working from the Digifant pro training
manual. It doesn't reference that fifth pin. It looks like it triggers the
high speed fan when AC is in use. I left the AC setup off for my post fire
rebuild so it's kinda moot. :-)

BTW the whole circuit started working while I was moving those relays
around testing voltages and grounds. I'm guessing the fault lies in the
wire bundle just ahead of the back box that took some heat in the fire.
Till I can get in there at least I know what to wiggle if it quits.

I put the pro training pdf on my phone ;-)
