This thread was consistant for the 02 and 04 so it is sure to be good for the 03.

brunetmj, I'm on nasioc.com a lot too. I have an 02 WRX. It has the same wiring as a 2003. The 2004 wiring is different on a few things.

Anyway, check out the security forum at nasioc, you'll get more info there. You can also PM or email me, I know the car well.
