Want to add a tach

My truck is an XL and I dont have a tach in the gauge cluster.
if I replace the gauge cluster with one that has a tach (XLT) do i need to replace the wiring harness?

I know its possible on the 92 to the 96, I would think it would apply to the 97 on. I believe the harness is wired and should be a plug and play swap.

Are you saying the truck wont start once I change the cluster or
I will not have the blinking theft light on the new cluster
or both?
I prefer not to disable the PATS .

The truck will not start after you change clusters. The PATS system marries the cluster,key and PCM to each other,and you cannot change any of them without reprogramming the PATS system so it will work.

No,the programming is in the PCM,and the truck has to be there.
