hey i just bought a 2" tach for my car i need to know what wire i will need to use to get my feed for the tach.. i know what power and accesorie i will use i just need to know were i need to splice into for the coil pack..
What wire do the instructions for the tach say to tap into? I don't think anyone here as an aftermarket tach (most people just switch to an upgraded cluster with the tach in it, myself included), so the information would be helpful to help us figure out exactly what wire you would need.
Also, what year and engine do you have?

There are a few places you can tap into. The best place would be the tach lead at the instrument panel harness, but if you can't get to that, your next option is at the ICM (ignition control module) at the tach output.
hi all first timer here look for similar help regards adding a tach i have an 04 with a 3.4l and im having trouble finding the pin neccesary to wire the tach into. it is my understanding that the white wire is located in the larger connector on the right hand side of the icm but when i wire into that i get no result from the tach?? any help would be appreciated.
