Here is a link to the Compustar alarm systems manual where it talks about manual transmission vehicles. The part you are interested begins on page 8 of the pdf file.

Here is an excerpt from that page for those of you who don't have the Acrobat reader:
Reservation Mode (manual transmission only)
In order to auto-start your manual transmission car, you must first set the CompuStar system to Reservation Mode before leaving your vehicle. The purpose of Reservation Mode is to leave the transmission gear in the neutral position when you leave your vehicle. Reservation mode is intended for use in MANUAL TRANSMISSIONS ONLY and NOT FOR AUTOMATIC TRANSMISSIONS. Reservation Mode must be engaged each and every time you leave your manual transmission car in order to auto-start the vehicle.
Activating Reservation Mode (MANUAL TRANSMISSION ONLY)
Step 1: After arriving at your destination, and BEFORE TURNING YOUR ENGINE OFF, place the transmission in the Neutral position.
Step 2: Remove your foot from the foot brake.
Step 3: Activate the parking brake.
Step 4: Remove the key from the ignition. The engine will remain running.
Step 5: Exit the vehicle and close the door within two minutes after activating the parking break. The engine will shut off and reservation mode for the remote
starter is now complete.
It does seem like a lot of steps but it is one option for you manual transmission guys...
