You set me on the right path !
In parts manual 6600992 under Special Accessories (as you said) but on page
ZU13, they have the washer stuff
Screen Washer Kit Control Unit 1201389 is superceded by 1228662.......but
where and what is the difference?
Seriously, we will probably never know. But, it certainly isn't what was
sent me. The sender appears to be surprised also.
Thanks for getting back to me and your help.
