Remote starts can be put on manual transmission vehicles, but they require the emergency brake, door triggers, must run of tach sense and not voltage sense, and a relay on the clutch switch to be wired up as well. Safely operating a remote start require a procedure for manual transmission vehicles. Usually you have to have your foot on the brake, press the remote start button, pull the emergency brake, remove the key (Car still running), exit the vehicle, then lock, and the vehicle will turn off. This puts the vehicle in a stasis mode where it is as sure as it can be that the vehicle is in neutral. If the door is opened, brake pressed, or emergency brake released the vehicle will not start remotely because it doesn't know if the vehicle is in gear or not.
