Ended up using the later model switch that came with my aftermarket combo valve. Unfortunately, the wire connector is different, but that's no big deal -- just another PITA to deal with.
This is probably not your problem, since your switch closes only when you step on the brakes. But I just wanted to get this info out there -- the light flickering or being on all the time could indicate a bad ChiCom switch.
On another note, that's a dual 8" booster, right?

Yep - 8" booster. I did flush mount to the firewall, which I was thinking may be a problem, but judging by what others have told me I am thinking I have some air really stuck. Im going to try a heavy hit to the pedal with the bleeders open and see what it gets me. Hopefully not a mess to clean up!

IF you still have the differential pressure valve moving, then there's air or fluid loss somewhere causing a....pressure difference

I actually did adjust them to the point where the wheel wont turn. Still the same. I am thinking I have a huge bubble somewhere and its possibly in the rear circuit at the prop or in the prop valve.
