Do you have factory keyless entry and alarm? I don't think they started chipping the keys until 2000, but if your factory system uses an RFID key system to prevent hotwiring you'll need a bypass module.

If all these answers are no, did the system you bought come with alarm and keyeless entry? Of course that makes it a bit more complicated.

You pay $25 and you can get the wiring diagram for every circuit in your vehicle to help you identify what wires to tap into.

the rest I would assume is following teh directions that came with the kit. I am going to deal with my girlfriends' jetta after Xmas.
