Remote start question
 

I did a search but couldn't find my answer.
Id like to buy a remote starter kit for my 07 Pony Pkg Mustang AT.
I am looking at the 7L3Z19G364AA kit but it says I need a PATS which is most likely this: 8L3Z19G365BA

Now my question is, doesn't our cars already have PATS installed in them?
Or would I need to replace/add it with 8L3Z19G365BA?

Im a little confused...Im going to do more research but thought I would ask first.

Your car will have pats but if you add a remote start you need a bypass kit for the pats. Unfortunately I don’t know the part numbers.
