Wiring:
BLACK - connect to a good ground point in the vehicle.
RED - connect to switched 12 volt power point.
(An accessory terminal will work for this.)
ORANGE - connect to a constant 12 volt power point.
(This will keep the correct time.)
BLUE - connect to the tail light circuit.
Mounting:
The gauge requires an oval cut out that as shown below. It should be inserted into the opening from the
front and the U-clamp will be installed from the back. Tighten the two nuts on the U-clamp so that the gauge is
secure. Figure 2 shows the required cut out for the gauge. Figure 3 shows how the gauge mounts.
