Pre-Wired Installation ON STAR

Pre-wired Installation ON STAR:

On certain markets there is a 2-pin connector 619 by the telephone connector.
Pin 1 is connected to pin 39 on the SRS/airbag control module.
Pin 2 is connected to grounding point G4.
The connector has a built-in short circuit brace that means that pin 39 on the control module is grounded if no connector is connected to 619.
