I have a base model 06 2IS and did the ISP install. Even if your car has the plug, you'll still need to splice the wires into the door switch, unless you have the sport package (which by seeing your replies, it seems that you don't). Click on the link referenced in that other reply or search for the ISP install thread. It's a real easy hook up!! It's not as easy as plug and play, but it's not hard at all.
