To control the engine throttle, use pin e for electronic throttles which take pulse-

width modulated signals (such as Caterpillar ECUs)

†

, or wire pins b and c to direction-

control relays for motor-driven throttles.

The Switch Inputs (pins m, n, p and q) are best switched to the +5V Power

supplied from pin r, although they will work fine if switched to +12V.  The +5V from pin
r is preferred because it is already protected against short circuits.  Do not feed +12V
back into pin r.

(ground).  Do not power them from +12V or any other ground.
