How to install gauges into a location without dash or park lights
When wiring a gauge into a location other than a car dashboard (for example, in a caravan), Park and Dash lights may not be available.
The below diagram shows how to install a gauge using switches to simulate ignition and dash-lights, providing a simple way to switch the Gauge ON/OFF both With/Without the backlight active. The current draw of the backlight is approximately 40mA per gauge.
The Secondary connector should be wired according to the wiring diagram in the Gauge's user manual.
