3.) Speedometer - White (Intellitronix Speed Sender to replace factory cable drive) -
Disconnect the mechanical speedometer cable from the transmission and insert the new electronic
sensor into the transmission. This panel 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
wire will be switched power (12vDC) and black wire will be grounded to the ENGINE BLOCK
NOTE:(Twist all Three wires together and this 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
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. The resistor in the adapter
kit will help pull a stronger signal for the tachometer.
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 for Tach signal output.
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 it 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.
1. Sets # of digits in RPM display, using button, display shows: (hundreds) 8800, (tens) 8880,
and (ones) 8888.
2. Sets # of cylinders using button, display shows: 1cy, 2cy, etc.
3. Sets first digit on max RPM on gauge bar display (in thousands) using button, display shows:
1000 to 9990. You will need to hold the button till you reach the desired range. If you miss
range, you will need to go around again.
