CABLE BUTTONS
Trip/Cal Button - Grey Cable Button or Push button on Dash - There are two grey wires
connected to the push-button for 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.
Fuel – Yellow The fuel gauge sending unit is not normally supplied because the display system
can use the existing fuel level sending unit in the tank in most cases. If your wiring harness already
has a single wire routed through the vehicle for the fuel sender, then it may be used. If using a wire
from an external harness, make sure that the wire does not have power. Fuel senders reference
their ground from the sender mounting plate. Connect the yellow wire to the factory sending unit.
Note: The gauge is preset for GM 0-90 Ohms
Fuel –Black/Yellow – Run a new ground wire and attach to your Fuel sending unit housing to ensure
proper fuel gauge operation. If the sending unit does not have a sufficient ground, it will not work
properly.
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.
