2-Inch Gauge Clusters
The 2-inch gauge clusters hold both standard and
optional gauges (Figure 3). The clusters install the
same way as the baseline cluster, but the individual
gauges (Figure 4) have a “key” connector held in
place with a threaded collar. Each gauge is “daisy
chained” together with small jumper harnesses.
New Sensors
Special sensors are installed for this new system:
■
Air Pressure Transducer
■
Fuel Vacuum Transducer
■
Air Vacuum Transducer
■
Outside Air Temp Sensor
■
Inductive Current Sensor
■
Transmission and Axle Temp Sensor (same as
the T2000)
■
Pyrometer Sensor
Wiring Changes
Because multiplex gauges need very few wires, the
color codes and designations of wiring will be
improved to help technicians troubleshoot. Three
connectors plug into the back of the ICU (Table 1) –
a 9 pin, a 40 pin, and a 52 pin.
Here’s how it works.

Wire colors will be reduced from more than 220
to 10. The new instrumentation color codes are
as follows on page 6.

Data Bus Communication
The multiplexed instrumentation system uses several different data links to transmit input/output data from other systems
to the Cab Electronic Control Unit (CECU), and ultimately to the Central Instrument Cluster and CVSG Gauges See
