NEUTRAL INDICATOR
The neutral indicator is activated by a ground connection to the white wire on the 5-wire indicator
harness. This will interface with the stock neutral switch on the transmission.
The neutral indicator appears as a pair of vertical bars that flash on the left side of the speed display.
The neutral indicator is disabled in trip display, odometer display, and speed cal modes.
LOW OIL PRESSURE INDICATOR
The low oil pressure indicator is activated by a ground connection to the brown wire on the 5-wire
indicator harness. This will interface with the stock oil pressure switch on the engine.
When there is a ground to the brown wire the speed display will flash “ LO “, “ OIL”. Pressing the push
button function switch will toggle between the speed, trip, and lo oil displays. The low oil indicator is disabled in
speed cal modes.
TURN SIGNAL AND HIGH BEAM INDICATORS
The right turn, left turn, and high beam indicators are activated by 12 volts at their respective hook-up
wires on the 5-wire indicator harness (not the 3-wire harness). The right turn signal wire is green, the left turn
signal wire is black, and the high beam wire is red. These can be connected to the same wires that the indicator
lights are connected to. The display system wire colors may not match the wire colors in your electrical wire
harness. The turn and high beam indicators are disabled in low oil display, trip display, odometer display, and
speed cal modes. This system does not have a wire for automatic turn signal canceling modules.
