sensitivity on alarm system

I have a 98 outback and have adjusted the sensitivity on mine.

It was under the dash on the driver's side. It was a rectangular box about 2 inches by 3 inches that was attached (zip-tied) to the steering column. You don't have to take anything apart to see it. You can just lay on your back in the driver's floorboard and look up @ the steering column. You will probably need a flash light. Once you find the box, there is a little knob sticking out one of the sides of it. There should be an arrow on it that indicates which way sensitizes and desensitizes it, etc...

Don't set it to be too sensitive, or a vehicle that has had one of those overdone exhaust systems can set it off ina parking lot somewhere just by driving by. I had to de-sensitize mine a little bit because I had a neighbor w/ a dodge ram w/ exhaust that would make it give warning chirps by just driving past. If he wanted to mess w/ me, he'd just stop next to the car to set it off.

thanks a lot for the help, i tried looking but can not as of yet find this box, there is a lot of stuff under there! it is not ziptied to the steering column, but is probobly under there somewhere( if yours was there it must be in the same general area)thanks again david

This may not apply for you, but I'm pretty sure (!) that the sensitivity adjustment for the WRX alarm is on a cigarette-sized box in the center console...bolted in near the parking brake.

On the WRX there is a weird looking black box with some coils and stuff in the trunk, mounted in the top-right corner... could that be something?

I've found that same module and wondered myself, about it's function. It's not for the OEM alarm, because I installed one myself, and that wasn't a part of it.
