Well found Sean.
That was a really good find, I'll spend hours on there.

That makes sense of course, but I'm applying these principles (among others):
1. As far as possible leave the existing main loom alone
2. No open/exposed connectors under the bonnet as it's open to the elements

Making a break in the fly lead does add an extra joint in the leads but also gives flexibility to swap easily between the variants.

Appreciate that, but if you ever opened up existing looms you will see a lot of 'connections' right in the loom made in factory, so even factory looms are a bit messy. With availability of Certoplast it is possible to create a 'T' in the loom which is indistinguishable from the original factory wiring. I can assure you.
Even under bonnet and even wiring right near the engine. My wiring for Xenon level sensors, for washer water level sensor, radiator temperature sensor was not in good condition and it is possible to create quality repair that will be as good, if not better than factory wiring.
If you will ever need help to properly do wiring I can meet you and help doing it.
For experiments I would T from existing wires (not the heating elements for now, since they are not important at the moment) and I will use simple WAGO connectors to quickly connect and disconnect the washer jet. When solution will be identified, I'd solder in Audi native connector there, so that you'll have all options to connect: 1. Genuine washers 2. New washers 3. Both :)

Really looking forward to finding a contemporary, hi-performance washer jet that will point to proper windshield area without modifications to both scuttle panel and the washer itself.

Oh yes, I know that, I've done it myself and have a good supply of Certoplast. +++
Had to do it a while back to disable the auxiliary coolant pump on the current S8.
(Though now I know where the likely connector is I wouldn't need to on another S8)

Interesting, just had a look at that and their approach seems both brutal and unnecessary.
1. The Skoda parts are fan jets, look good.
2. Connectors look the same as Audi D2. Better.
3. Size looks VERY similar, I think there may be an easier way to fit them without modifying the panel.

I'm going to see if I can get a cheap pair to experiment with. Part number is 6Y0 955 986.

Edit: Alternative part number 5J0 955 986 available from China for £7 each. There are triple-jet and fan versions of these as far as I can see, not sure how the part numbers correspond.
If nothing else it will be probably the cheapest way of getting the connectors!

Following with interest.

You should be given an award if you find jets that will fit podiums and can be adjusted to accommodate aggressive slope of those podiums.

I'm pretty confident the Ford Focus ones will have the correct angle, or be adjustable to it.
Not so certain about the Skoda ones as I've not got my hands on them yet, but I have some ideas that are a lot more elegant than the Russian solution!

Either way it's all coming from China so quite a wait now. :cool:

All good things come to those who wait

I wonder if they're the same ones as on a BA Falcon?
My missus' old Falcon had fan style spray nozzles.

If so, it'll be easy to find a set!

Falcon is Ford, so probably the same as the Focus. ;)
