Wiring up heated syncro/LT mirrors
Syncro mirror arms were originally non-heated whereas some LT arms were sold with heated mirrors with the wiring fed through the arms.
However heated LT mirrors can be bought from VW cheaper than standard mirrors (281-857-547C) and they are the same sealed unit as Syncro mirrors but have wires attached. The wiring can be neatly tie wrapped to the mirror arm and fed through the hole in the door.


Then wire them up according to the diagram below

Job done. Now you will have clear mirrors and misted up side windows
