2. Connect the main BLACK wire to a ground source. Note that there are other black wires
coming out of the 2 pin and 3 pin connectors, these are not the main gauge grounds. Avoid
noisy ground sources, such as grounds used for the radio and or ignition.
3. Connect the WHITE wire to a headlight power wire (a wire that supplies current when the
headlights are on). This enables the display to dim for better nighttime viewing. DO NOT
CONNECT THIS WIRE TO THE HEADLIGHT DIMMING WIRE. Connection to this rheostat
type of switch will cause the gauge to malfunction. If you chose not to utilize the dimming
feature, connect the WHITE wire to ground.
2.2 Water Temp Sensor Wiring
1
Fish the Water temp sensor’s two pin connector through the firewall and to the MTX Water
Temp/ Volt Gauge.
2 Connect the sensor’s male two pin connector to the female two pin connector on the gauge.
3 Coming out of the female two pin connector of the gauge you will find a black wire with a
stripped end. Connect this black wire to the same ground source as the gauge.
2.3 Voltage Input
There is no additional wiring needed for the voltage input. This information is acquired from the
gauge’s main power source.
The three pin connector on the gauge is not used.
