How to wire a tach
Posted 23 June 2003 - 11:36 PM
today. The wiring is prety stright forward. Except for the wire for the tach signal. The instructions said to wire it in to the
ignition module, but some one else said to run the wire to the power train module which is located behind the power steering
reservoir to a white wire with a black stripe.
Has anyone hooked up an aftermarket tach (I'm sure you did)? If
so did you hook into the ignition module or the power train module?
All input is greatly accepted.

Some later 1998 models through 2000 have the white/black stripe wire already pre-wired for the instrument
cluster. I would suggest looking there first before tapping directly into the PCM - That is a last option idea because any
short of that signal will cause other systems to malfunction... (I.E. Auto trans, Cruise control...)

the 'powertrain' and 'ignition' module are one and the same!
