I tested the pedal switch by applying vacuum at the pump using mity vac and
then stepping on the brake pedal and observing the vacuum bleed off. Mity
vac has a vacuum gauge, so I pumped about 15 psi of vacuum, which pulled
the throttle all the way back. When I tapped the brake pedal the vacuum
bled off and the throttle returned to its normal position. I think the
pedal switch works really well at this point. I left the vacuum on for a
while and when I came back it was still there until I tapped the brake.

I believe my problem is in the module somewhere. I don't think I am getting
activation signal to the pump. I will try to make an LED light fixture to
observe the pump signal tomorrow. A known good spare module would be really
nice to have right now.
