• Backlighting for 2-inch electronic gauges is sent from the CECU to the gauges via the data link (blue wire).
• Optional mechanical gauge (i.e. air suspension) needles are driven mechanically with air pressure. There is
no red warning lamp and the backlighting is powered through the brown wire from the CECU (a pulse-width
modulated signal). The 4-way jumper harness is still used to pass all 4 circuits through the gauge to the next
gauge in the chain.
• Specialty CVSG gauges (i.e. clock, PTO hour meter) are stand alone gauges and are independent of the
CECU.
• Gauges can be relocated to any position in the dash. To relocate a gauge unhook the connector at the back
and move it to the desired position. Plug the jumper wire in. (See Figure 8-6 for instructions on physically mov -
ing the gauge). The connector will require a firm pull to remove it. When reinstalling the connector ensure that
it is fully inserted. Both connector sockets on the rear of the gauge are the same, either one can be used.
