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.
If your vehicle has a GM HEI ignition, connect to the terminal marked ‘TACH’, or, on some sys-
tems, a single white wire with a spade terminal.
If your vehicle has an after-market ignition –some systems will connect to the TACH output ter-
minal.
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.
Note: If doing an LS engine swap, pick up the tach signal wire from the ECM/ECU and then set the
tach switch to 4-cylinders.
To set the tach, use the Tach Selector (DIP Switches), which is located
below the tachometer display. The default tach setting is for an
8-cylinder engine, (both switches UP, as shown).
For a 4-cylinder engine, set the DIP switches as
Switch 1: DOWN and Switch 2: UP.
For a 6-cylinder engine, set the DIP switches as
Switch 1: UP and Switch 2: DOWN.
To recall the highest RPM achieved, simply press and release the button near the tach readout. To
reset the peak RPM value, press and hold the button until the RPM displayed value is zero.
Speedometer –White Disconnect the mechanical speedometer cable from the transmission
and thread the new electronic sensor onto the transmission. This unit comes with a 3-wire sensor.
If you are using this sensor, the white wire is the speed signal; connect this to the speed signal
wire on your gauge. The red and black wires in the cable are switched power (12VDC) and
ground, respectively. Twisting the ground and signal wires around each other will provide an
additional level of interference protection. The speed signal wire should not be routed alongside
the tachometer, ignition, or any other high-current or high-voltage wires. For vehicles which have
a vehicle speed signal from a transmission -- one wire goes to the speedometer, and the other to
the ground -- or ECM. Tap into the VSS wire (consult a vehicle service manual or wiring diagram
to determine the correct wire color) and connect it to the white speed sending wire on the digital
dash.
Note: If your vehicle is equipped with an electronic transmission, there will be an electronic vehicle
sender with either two or three wires.
DIGITAL PERFORMANCE SPEEDOMETER
Your Intellitronix dash panel is equipped with our Digital Performance Speedometer. This elec-
tronic speedometer displays speed and includes an odometer, trip meter, high speed recall, 0 -
60 time, and quarter-mile elapsed time. It can be calibrated with the push-button to adjust the
speedometer for different tire/wheel sizes, and/or gear ratios. The single push-button is used by
a quick tap to toggle between odometer and trip meter. The microprocessor distinguishes
