Definately 94-95, possibly (I think) 93 was the first year. keypad was not available in 96-97, which is a bummer, I miss that about the 95 I had. My guess is that you would need the body harness, but you might want to grab a 94-95 keyless module from a car that had the keypad and see if it will plug in, your code on the door would change to whatever that module is programmed for, but it would work with a factory remote. There is probably more wire swapping to it than that though. I'd love to do it on mine, but it would mean either cutting a hole in the door for the keypad, or replacing the door with one from a pre-96 car....but if you already have the keypad, somehow that makes it seem a bit easier.
