how do I hook up a tach
For '93 and '94, depending on the size
of the motor, you can do the following. 2.3L - off the PCM(powertrain control
module) go to pin 4, which is a tan wire with a yellow stripe. Or, go to the
ICM(ignition control module) and splice pin 12, which is a tan wire w/ yellow
stripe - this is the same for the 4.0L, too, except for the ICM connection, it will
be pin 2 instead of 12. For the 3.0L, off the PCM the tach signal will be pin 4,
which is a white wire with a pink stripe. Or, you can go to the ICM, and splice
into pin B, which will be a tan wire with a yellow stripe.
