Tachometer; Speedometer - Intellitronix DP3001 Installation Manual

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.
The default setting for the tachometer is for an 8-cylinder engine.
For 4-cylinder engines, cut the orange wire loop.
For 6-cylinder engines, cut the blue wire loop.
Do not cut both wires and leave disconnected or the tachometer will not function

SPEEDOMETER

1.)Speedometer – White - (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
2.)Speedometer – White - (Factory two wire sender no PCM) - Most vehicles built after 1984
have an 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
3.)Speedometer - White (Intellitronix Speed Sender) - Disconnect the mechanical speedometer
cable from the transmission and thread the new electronic sensor onto 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 and black wires in the cable are
switch power (12VDC) and ground, respectively. 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
