Tachometer (memory capable) – Green
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.
To change settings:
The display will stay in Settings Mode until it receives a signal from the ignition system. To program the
unit after starting the engine, shut the engine off and turn on only to the accessory position.
When in accessory mode, the settings menu will scroll through the settings menu. A light tap on the
button engages the menu system.
