Dear Sirs,

Can anyone help me with this most puzzling problem ?

I am trying to hook up a tachometer by Auto Meter to a 95 Eagle Talon 2.0 liter non turbo model. I'm looking for the Tach Signal wire that would work best for it. I looked already in your Intsaller Data Base for the wire lead, and found it listed to be a white wire located on the PCM. However, I also looked it up on the internet site for Rostra, and they list it as being black and red, located on the engine. Which one is right ?

use a DMM and test the wires. the tach is ac voltage and will usually read 6volts or so and increase with accelleration.

for what it's worth some times best to use the wire on the pcm like cars w/o distributors and after market engines u have use the tach one the distributor or the coil
