    I just can't come up with a good reason to go through the trouble (minor trouble, admittedly) to buy the special alarm battery and install it. My 355 is garaged, there's an early 911 next to it that is more valuable and easier to steal, and my wife's SUV is parked in front of the garage at night. Nobody's getting my cars. Would rather unplug the LED and be done with it.

    No need for tape: It is very simple to pull the AC vent and the LED can be unplugged

    It's easier when the case is held together by screws. Mine was a sealed type and I had to cut it open with a box knife. It took ages and I'm lucky I didn't cut myself. The plastic is quite hard. I put several layers of aluminium tape next to the line where I was cuttings, so that if I did slip, I didn't mess up the case. You have to go slowly, otherwise you will cut into the internal locating tabs. After all that, I decided to buy a new one. I wasn't sure if the glue would hold.

    I took the wheel off and went through the wheel arch rather than going from underneath. My arms were long enough to reach the siren even with the washer bottle in the way.

    Drove in to work today and you are indeed correct. I tinkered last night with the alarm module and it's the sealed type. Not gonna try to cut it open, it'll go in my box of 355 spares. Time to unplug the LED. I guess I'll have to de-sticky the HVAC vents while I have the center one out, it's not too bad but definitely original and sticky. One project leads to another....

    I'm not sure if there is any easier access to the wiring for the LED. There is one(20 pin) connector between the Immobiliser ECU and the LED plug, but I'm not sure where it is.

    Connector 59302
