Re: new wiper switch
I warned you a long time back that it would be problematic adapting a non-VW wiper switch to a VW wiper motor - if the switch you purchased is a 141 955 517A it should be easy ...First, though, you'll need to successfully upload a picture or the circuit diagram (it didn't come through above).

Re: new wiper switch
This looks like the pinout for that dual-motor switch
B: power in
W: washer power out
1: Motor 1 Low
2: Motor 1 High
3: Motor 2 Low
4: Motor 2 High
5: Park (both motors)
But without knowing how the terminals work on that switch (particularly the Park), I couldn't speculate how to wire things, whether the park function will work, won't work, or will short out / blow fuses.
Plus, your 71 KG already had a dash switch, so why not just buy a direct replacement (the part number Marc gave)?

Re: new wiper switch
I'll buy a new original switch. I am having health problems now so it will be a while.
Thanks for all the input.

Re: new wiper switch
Speedy Jim has a nice diagram which shows how the stock switch operates; you could check the switch you have now with an ohmmeter to see if it conforms functionally, but I doubt it -- a stock switch is guaranteed to work.
The problem with the stock setup is the washer system. Since there's always pressurized fluid at the switch (until the spare goes low enough for the washer-bottle-cap regulator to cut it off) there's a possibility of a leak that'll hose down your radio. It's not hard to gut the water-valve from the switch and install a microswitch in its place; that can be used to trigger a relay to power an electric pump. Mount the bottle/pump high enough and you won't have a significant drainback problem (causing delay of the washer squirt initiation). You can also employ a checkvalve intended for aquarium airline to prevent drainback.
