Jake needs a closed contact on the clutch pedal, a closed signal from the air brake pressure switch, a power signal from the dash On/Off switch, and a signal from the ECM that the throttle has no, zero, none pressure on it. The power signal appears to be getting through, as the dash indicator...indicates. Our T2 has problems with the air brake switch and corrosion. At least once a year, reach up under the dash from the ground. Wiggle the wires, good for another year. The first indication of corrosion is the cruise control randomly dropping out.
