if you search i-club.com for "alarm turbo timer" or something of that sort, you should come up with your answer. i can't exactly remember what you must do, but it has something to do with the keyless entry wiring harness under the driver's side lower dash, and the alarm "brain" in the center console sweet, next to the parking brake.
Yep, saw that post. It is for WRX's with turbo timer. Don't know if I can do the same if I don't have the timer. It only calls for capping off the 2 wires by the hand-brake. I would like to know if I can achieve the same result without having the turbo timer installed.
