• 4-way jumper harnesses link CVSG electronic gauges together, by a daisy chain system . Pin out is as follows:
Pin # Color Function
1 Blue
Data, backlighting for Electronic Gauges
2 Brown Backlighting for Mechanical Gauges
3 White Return
4 Yellow Power
• Backlighting level for CVSG electronic gauges is sent from the CECU to the gauges via the data link (blue
wire) .
• Optional CVSG mechanical gauges (i.e. air suspension) are driven mechanically with air pressure hosed to
the fitting behind the gauge. 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 .
• Gauges can be relocated to any 2-inch open gauge position in the dash . To relocate a gauge unhook the con-
nector at the back and move it to the desired position. Plug the jumper wire in. (See “Accessing Gauges and
Switches section below for instructions on physically moving 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 .
