It is possible to install a remote starter system into a manual transmission vehicle. The installation requires wiring to disable the clutch interlock and verify the engagement of the parking brake. There are multiple ways to ensure that the transmission is in neutral, which is required for safe operation.
One of the safest approaches to determining if the transmission is in neutral is a specific sequence of actions by the driver. After parking, he activates the system, which allows him to remove the key and exit the vehicle while it is still running. The system turns the engine off when the door is closed. The remote starter mechanism disengages if the door is opened before it receives a signal to restart the engine.
