Convertible Vehicles - sensor by spare tire?

just looking around the other day and saw a black plug that said sensor on it, anyone know what this is? actually I was checking to see how/if the dent doctor could remove a slight door ding out, wish I could've seen the dipwad that did it, sorry for the rant.

If I remember correctly it is part of the alarm system. Sensitivity, perhaps, I can't recall.

yeah, what he said, that little black box is the sensitivity adjustment. If u crank it all the way up like me, then a fart will set it off, always impressed at how well it worked especially being stock.

is it supposed to be attached to something? mine is just sitting on the spare tire connected to the wires of course. thks for the info.

ok, I figured it out, kinda cool, now on to fix that ding. thks again.

That's the shock sensor for the alarm system. I believe it was originally mounted w/ double-sided tape to a nearby body brace, but usually it falls off and is left dangling (and ineffective) as you found it. Need to ty-wrap it to the body brace.

ya that's what I did, to the plastic piece in front of the spare, but it's not quite as sensitive now, is it worth adjusting or will it only detect a bump in that corner of the car?
