It all depends on what year your Fox Body Mustang is. Most multifunction switches from 87-93 use the 9 pin setup ( WPT472) but there are a few out there that did in fact use the 4 pin setup. You would have to verify on your vehicle which one to use.
As far as replacing the connectors, It would be a really good idea to go ahead and replace them all, while you are in there.
