This is the best way to convert 12v DC to 6v DC and not be concerned with the 12v ground. Please tell me if you have questions. You will need a converter which has a high amperage output for your wiper motor. This one (10 Amps) should be okay.

This is the one I have: https://www.ebay.de/itm/392277556500


Description says: High power 12 volt to 6 volt 25 amp regulator. .. This unit can also run blower motors and wipers that are 6 volt. Wide input range from 8 to 40v, output is fully protected.

That's what I wanted to hear :-)

Thanks, Frank
