VW do their own thing with wiring...
Two speed wiper motor.. Connections
30 wire power to the switch thru a fuse..
53b needs to be earthed from the switch...
Wiper motor connections are usually marked.. 53 53a 53b etc
You just need to hook it up to the switch...
to check out the circuit diagram
look up
http://vintagebus.com
on the LHS click on Wiring Diagrams
then go down past all the Bus wiring diagrams until You come to 1968-69 wiring diagram
click on the button
go to the RHS of diagram and You will see how to hook it up - switch to wiper motor... fairly simple..
the VW wiper switch is heavy enough to use without a relay... although one can be used...
cheers
