Questions about headlight wiper/ intensiv-reinigungs anlage

Hello fellow E28 enthusiasts.

I have purchased a complete headlight wiper/intensiv reinigungs set, which I want to retrofit in my E28. I have searched the archive and I've read the EBA that was posted by Fabs some time ago, which helped a lot. Most things are clear to me but I still have some questions, of which I hope someone has an answer to.

1: I've read in Fabs' EBA that there was a problem with a valve of which he didn't know a part number of, anybody know if this is solved? (Would be great if he could answer that himself, if English is no problem). Or, anybody knows how this is supposed to be hooked up, or has a part number for that valve? The ETK only shows one, number 61 66 1 380 464, but that is the one for the headlight wiper nozzles, right?

2: I'd like to know how the hoses between the pump and the headlight wiper nozzles are routed. I can't find that anywhere. There is a T-junction used, is that originally placed before the right headlight wiper or somewhere in the middle?
A picture or approximate drawing would be great.

I want to retrofit this system as originally as possible, so any information about these questions is more than welcome.

Thanks for your time. <img src=http://bilder.parsimony.net/smilies/smile.gif alt=smile>
