My 95 4-door has factory cruise - yup, the vehicle harness is pre-wired for the cruise components. But that doesn't mean those wires will just plug in to your aftermarket unit.
My 95 2-door (my trail rig) has an aftermarket unit added on (extra stalk on the steering column, etc.) It's just a matter of time 'til I rip it out. It never worked right, even when the rig was still bone stock.
