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 555-41614. 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.

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.
To set the cylinder selection: With the ignition off, hold in the right button and power the dash on.
The tach will then enter a setup mode where the needle will move (between the zero and one on the face
of the instrument) to indicate 400 (4 cylinder), 600 (6 cylinder) or 800 (8 Cylinder) continuously.
When the needle gets to the desired setting, tap the right button once more. It is now set and will enter
normal operating mode. To see the high RPM/tach setting, hold down the right button. It will reset after
five seconds.

- (
Factory sender with Powertrain Control Module
) When using a LS engine
swap, you will need to pick up the Speedometer signal wire from the PCM Pin 50 on the red connector.
(This pin may Differ. Refer to your vehicles Pinout Chart for accuracy). Any other Computer based engine
will need to use to use the PCM/ECM to run the speed signal for the Speedometer.(Consults Pinout Chart)

- (
Factory two wire sender no PCM

electronic transmission sender. If your vehicle is already equipped with an electronic transmission, then
the electronic vehicle sender will usually have Two wires attached to it. One connects to the Signal wire on
dash (we prefer this to be high output). The other wire (Low output) Ground at the Engine block. To find
High and Low output wire color or pin location will need to be looked up by Vehicle vin or Model and year
or (Consults Pinout Chart).
