I am in the process of installing the 791xv on my car. DEI does not recommend that you install the remote start with your manual transmission, but that doesn't mean you can't do it. You just have to get creative. For example, to make sure the car can't start when it is in gear, you can stretch two small steel springs across your shift gate above and below the gear shift so that when the it is in neutral, it is touching both springs, and when it is in gear, it pushes one spring up and loses contact with the other. If you hook the remote start activation wire from the brain to one spring and the wire to the remote starter relay to the other spring, the car will only remote start in neutral. You also have to disconnect the system that checks if the clutch is engaged, I haven't looked up how to do it yet, but I'm sure it's on this site somewhere. Obviously, you want to get in the habit of leaving your car in neutral when you park it. Good luck.
