I think my alarm may be upgraded/changed. Does the factory alarm have any Code Alarm components? My sensitivity controller says Code Alarm on it. I believe Circuit City used to sell these alarms, so I was guessing the guy I bought it from had an aftermarket alarm installed. Never paid much attention to it. Still uses the factory key fob's tho...
now that you mention it, i think mine DID flash when i had the factory alram still installed... io think there is some cross wiring that the factory alarm does that causes the fogs to flash since they tie into the running lights. i think the factory alarm will flash everything when it arms. the regular keyless system only flashes the turn signals.
