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.
Note that many vehicles, including most Hondas, have an illumination switched connector in the interior fuse box.
Depending on access to the wire – use a wire tap or splice the factory wire to connect the gaugeART CAN Gauge orange wire.
