Trip/Cal Button – Grey There are grey wires connected to the push-button on the speedometer
board. Mount the switch in a convenient location such as under the steering column so that you may
easily reset your trip odometer or other speedometer functions.

such as under the steering column so that you may easily set the other functions of the tachometer.
TACHOMETER
Note: If doing a LS engine swap, pick up the tach signal wire from the ECM/ECU and then set
the tach switch to 4-cylinders. You may also need to order the Intellitronix LS Engine Swap
Adapter Kit – for Series 1, 2 and 3 engines. The part number is 8014LS. If you are getting the tach
signal from the ECU, the resistor in the adapter kit will help pull a stronger signal for the
tachometer.
Tachometer – 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.
PROGRAMBLE TACHOMETER SETTINGS
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.
