Figure 1-13. Instrument Panel
f. Instruments. The Instrument Panel includes all gages that provide the operator with information about vehicle
condition and operating status. The speedometer (1, Figure 1-13) receives electrical input from the WTEC II Vehicle
Interface Module (VIM) on vehicles equipped with WTEC II transmission controls. The speedometer receives electrical
input from the WTEC III transmission ECU on vehicles equipped with WTEC III transmission controls. The WTEC II
VIM and the WTEC III transmission ECU are both located behind the kick panel. Tachometer (2) input is provided by
the engine speed sensor located on the engine flywheel housing. The fuel gage (3), oil pressure gage (4), water
temperature gage (5), front brake air pressure gage (6), rear brake air pressure gage (7), and VOLTS gage (8) receive
electrical signals from sending units. The sending units respond to changes in fluid level, pressure, temperature, and
DC current and send this information to the gages.
