4. Next, route and secure the sensor wire harness from the sensor into
the vehicle, close to the controller’s location. Be sure to use a
grommet when routing the wires through the firewall to protect them
from stripping.
5. Connect the red wire to a positive 12 volt constant (un-switched)
source either directly to the battery or to a fuse panel on the vehicle.
If wiring to an un-fused source, install a 3 amp fuse inline within 20
inches of the sources connection.
6. The white wire should be connected to a positive 12 volt ignition
(switched) source. It may be connected to the fuse panel, an accessory
wire, or any positive 12 volt source that turns on and off with the ignition
7. Connect the black wire to any good (unpainted) ground connection.
You may also route a wire directly to the negative side of the vehicle’s
battery.
8. The Night Time Dimming feature decreases the brightness of the gauge
face by 30%. Connect the orange wire to the 12 volt positive headlamp
source. This allows the mode to be activated when the headlights come
on. This step is optional and will not affect operation of the gauge if it is
omitted. NOTE: Do not connect the orange wire to a dimmer wheel.
This will cause the gauge lighting to flicker.
9. Reconnect the negative battery cable.
