Where does the permanent and keyless power supply come from in the Passat B6? How to connect a video recorder?
How to get power from the fuse box to power e.g. a video recorder?
The video shows the fuse box on the left side of the vehicle (European version, from the driver's side).
In the fuse box:
- in slot 17 there is + permanently,
- in socket 6 there is +, which appears after inserting the key into the ignition.
