Alarm Module Help:
 

Hey i have a 95 stang, and i saw a alarm module on Ebay taken from a 98 mustang. My car is wired for it, the harness's are there.
I want to buy it. But if i buy it and slip itin and plug it in, will it work? i also have keyless entry... will it work with my keyless entry? I took a pic of the spot in the truck with the wiresand whatnot where the alarm would go, ill put it up if anyone needs to see it, but what would i have to do to get it to work?
