line input and an ignition sense line input, wherein the device and system furthercomprises a control logic directly or indirectly connected to both inputs, and wherein,when not installed, the power supply status of both inputs is “LOW” and, whenproperly installed in a motor vehicle the power supply status of the permanent powersupply line input is permanently “HIGH” and the power supply status of the ignitionsense line input is “HIGH” when the ignition of the motor vehicle is “ON” and is“LOW” when the ignition of the motor vehicle is “OFF”. A method of the presentapplication comprises individually detecting the power supply status of the power supplyline input and of the ignition sense line input and, in response thereto, at least setting awrong installation status flag when a power supply status “LOW” of the power supplyline input is detected while a power supply status “HIGH” of the ignition sense lineinput is detected.
