The gaugeART CAN Gauge can dim illumination during night when the parking lights are on. Using the factory service manual, find a wire in the interior that switches to +12V power when the parking lights are on. Verify with a voltmeter or test light that the wire receives +12V when the parking lights are turned on.
Illumination brightness is configurable in the gauge settings.
Note that some vehicles, including many Hondas, have an illumination switched connector in the interior fuse box.
Depending on access to the illumination source – use a wire tap (example: Posi-Tap 20-22 GA – search Amazon.com for B0B3815XSG) or splice the factory wire to connect the gaugeART CAN Gauge orange wire.
Test the dimming function before reinstalling the gauge.
