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. If your engine is a LS the Tachometer will need to be put into 4 cylinder mode by
removing Resistors if the Tachometer does not have a push button for programing, please call
Tech Support at Intellitronix, as you may need to send the gauge back to us to be reconfigured.
There is no charge for this additional service.
Tachometer – Green wire
Connect the wire from the tachometer to the negative terminal of the coil or a direct tach output
lead from your distributor or electronic control module. If you are using an aftermarket capacitive
discharge ignition system, such as an MSD, you must use the designated ‘tach output’ connection
on the electronic box. Do not make any connections directly to the coil with this type of system.
With high output Ignition systems may also create frequency noise that may interfere with operation
of gauges that may require a tachometer filter.
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 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 or may
need a Tachometer adapter for proper operation of your Digital Gauges.
Diesel engines will require a Diesel Tachometer adapter for proper operation of your Digital
Gauges.
