The Interface Module features a DLC (OBD-II) Port, which provides the connection to your scanning tool or programming tool. There are two switches, to control both battery voltage and ignition voltage. The battery switch controls 12 volt power to the DLC Port, and to the constant power circuits of any connected control module. The ignition switch controls 12 volt power to the ignition power circuits of any connected control module. There is also an indicator lamp that illuminates when the ignition voltage is ON - a visual reminder to aid in correctly power cycling any connected control module.
A power supply cord (12 volt automotive style) is included.
