The After Key electronic power supply unit greatly simplifies the installation of all versions of the Termodiesel heaters for diesel filters manufactured by Protech, and any electrical device which must be connected "after the key" to the car's electrical system.
After Key, connected directly to the car battery, can power the device connected to it only when the key is in the ignition.
