What it reads

• Analog input 1 (brown wire) accepts any linear 0 to 5 V sensor such as oil pressure, fuel pressure, coolant temperature, intake air temperature, wideband AFR or ethanol content.
• Analog input 2 (blue wire) accepts any linear 0 to 5 V sensor for extra parameters you want to keep an eye on.
• Battery voltage using the power and ground connection for a quick check of charging system health.

Auto-dim at night

Link the green wire to a circuit that powers up with your headlamps, then enable the dimming option in the menu for comfortable night-time brightness.
