Have any of you installed an aftermarket tach in your trucks???? If so anything special needed or installing? I heard that I might need a multiple coil adapter or something like that, and is installation easy? (4.6) Thx

You need one of these to run an aftermarket tach, thats what i put on my car to make my aftermarket tach to work.

Ah right on ok thx a bunch, I new there was something special needed to add a tach!!

or you can just wire it to the #48 pin on the ECU for FREE

Ah ok even better.....thx

So in other words if I were to change out my cluster with one from a 97-98 XLT the tach wouln't work cause there is no wire in the #48 pin???

#1 if you change your cluster yer gonna have to take it to the dealer to get the miles set to your motor.... i thank that cost a good chunk of change , not sure.....

#2 mine didnt have a wire either.......

do a google search and u will find a link on other forums tellin u how to do it.......

well it wouldnt be that difficult to run a wire from point a to point b using a pin connector from radioshack

Big'un

exaclty mad , thats what the instructions i used said to use.... it worked fine......
