The part number is 273-0079, and was $5.49. The factory security module has a plug to allow connection to the HD siren. I just tinned the two leads from the siren, and inserted them into the first two slots shown on the plug in the photo. Then I taped it up with electrical tape to see if it worked.
It chirps when you turn off the main power switch to the bike (at the same time the lights flash to indicate the system is armed). It alos then starts chirping a warning when the bike is moved (sounds a few times and then goes off full tilt).
I haven't left it on long enough to seee when it resets (it's pretty loud and I have neighbors), but I assume it operates the same as the flashing lights, they flash for a while and then reset.
