Wiring check pretensioner circuit

[euroline07]

Hello,

I have a Ford Transit MK7 Euroline 2007. I would like to check and measure the wiring for the driver's seat belt pretensioner. The wires on the connector are colored green/blue and black/blue. Unfortunately, these wires aren't connecting to the airbag module. There's probably another connector in between. Does anyone know what colors the two wires from the driver's seat belt pretensioner are connecting to the airbag module? If there's another connector, where is it located?

Best regards and thanks for help
