From what I find in the schematics for this engine and in the manual,this truck has a electronic governor,it is a drive by wire system and the air/fuel mixer(carb) has two TPS sensors in it and a foot pedal position sensor in the pedal,there is no IAC control valve on the engine it is all controlled electronically with the governor/carb,the governor sits under the mixer,same as a velocity governor does but is controlled electronically.....
Wiring for the governor connector:
Pin1 pink/white batt + in
Pin2 tan/orange batt -
Pin3 black/light green analog return to ECM
Pin4 light blue/ dark blue TPS2 input signal into governor
Pin5 light green/red. 5 V Refrence wire into governor to know where butterfly position is
Pin6 purple/light blue TPS 1 input signal into governor
