Green – Tachometer
If your vehicle has a separate ignition coil, connect the green wire to the negative (-) side
of the coil – the wire that goes to the points or electronic ignition module.
To ensure that the ignition system does not interfere with any other dashboard functions,
do not run the tachometer wire alongside any other sender or input wires. Do not use
solid core spark plug wires with this dashboard system. Solid core ignition wires cause a
large amount of electromagnetic and radio frequency interference which can disrupt the
system's operation.
If your vehicle has a GM HEI ignition, connect to the terminal marked 'TACH', or, on some
systems, a single white wire with a spade terminal.
If your vehicle has an after-market ignition – some systems will connect to the TACH output
terminal.
If your vehicle has a Computer controlled ignition system, consult the service manual for
the wire color and location.
If your vehicle has a magneto system, connect the tach signal wire to the negative side
of the coil. Do not connect the tach terminal to the positive (+ or high voltage) side of the
ignition coil. Many tachometers, shift lights or RPM-activated switches will not read
directly from a Magneto, so your installation may need a Magneto Signal Converter to
function properly.
The default setting for the tachometer is for an 8-cylinder engine.

Note: The single push-button is used by a quick tap to toggle between odometer and trip meter.
The microprocessor distinguishes between a quick tap and a press and hold which will reset the
trip meter in trip mode or display performance data in odometer mode.
Programming/Recall Button – Grey There are two long grey wires connected to the push-
button on the board. Mount the recall button in a convenient location such as under the steering
