How To: Disable the 200sx SE-R Factory Alarm
I've noticed a couple people complain that their factory alarm went crazy, but no one really posted instructions on how to disable it. Mine has been going off at random, and I can't trace the problem. So, to keep my neighbors from killing me, I disabled it.
Locate the relay box in the engine compartment on the passenger side.
Pull the Alarm relay #1 (note a small flathead screwdriver will help pulling these out.) It's the second from the top left, and will stop the horn from sounding when the alarm goes off.
Pull the Alarm relay #2, which will stop the brights from flashing when the alarm goes off.
Note: There's a third alarm relay, and I can't figure out what it's for. I was hoping it was for the starter disable, but I can't figure out what it's for. If anyone knows, please post.
