Search this forum, there is a post on making a jumper to disable the factory alarm. But I am not sure what all the alarm disables.

Can't recall now, but if I remember correctly, the reference sensor picks up it's signal from the ring gear, the speed sensor uses the pins on the flywheel.

There is a magnet inside the reference sensor, about 1 1/2 inches long and maybe 5/16 diameter, be careful with your adjustment, if it catches the sensor catches the ring gear and tears the sensor apart, you get loads of copper wire and a magnet inside the bellhousing.

Ask me I know, mis-adjusted one, it caught on the gear tore open, and the magnet attached itself to the ring gear, jammed between the starter and the ring gear, and broke the aluminum nose of the starter.
