Voltmeter Installation

Voltmeter

1. Connect red wire from gauge to a switched 12v source (12v switched power source means that there are 12v to the red wire when the ignition switch is on and no voltage when the ignition switch is off)

2. Connect black wire from gauge to a good engine block ground

3. Connect purple wire from gauge to the night time dimming circuit. (The purple wire must be connected to the headlight switch circuit so that there are 12v to the purple wire when the headlight switch is on and no voltage when the headlight switch is off)                                              

NOTE: Gauges with optional memory feature will have a blue wire. Connect blue wire to blue wire from memory switch packaged with gauge. Connect black wire from memory switch to ground.
