I found a picture showing a BMW part 8366275-02 for the other connector (On a German Audi A4 forum)! With an Audi mate. :Confused:

Edit: RS seems to sell something very similar: https://uk.rs-online.com/web/p/products/8010755/
The connectors on the leads from the jets (I've just had a look) have no identifying marks at all as far as I can see. Surprised how small they are too.

Interesting discussion.
I wonder if there is a straight fit for D2 from newer cars
without modifications of scuttle panel or wedges.

Why we worry about matching resistance Andrew?
Different models of jets will have different resistance since
the new jets may require more or less heat to run.
The difference in wattage won’t be significant.

I think the biggest challenge is to find a model with matching geometry
that won’t require wedging, which I doubt because podiums on
D2 scuttle panel are not horizontal, but pointing upwards,
which means any standard jets from other cars will aim too high.

Thread in Russian of fitting skoda jets to D2 and modifying the podiums.
Brutal :)

I think the spray pattern is the main issue, hence the D3 thread concentrating on 3-nozzle or mist patterns. The Ford mist pattern is one I'm familiar with and like and luckily it fits easily.

The D2 has simple rectangular cutouts that the nozzle units clip into but later models seem to have much larger ones. It's probably fairly easy to fix almost anything to a D2 scuttle panel with minor modifications, I'm hoping for none.

As for resistance, that's just me being cautious, I expect almost all units for any vehicle to be similar, but as these are coming from China I just want to check that they're unlikely to blow a fuse.

Offhand, without delving into wiring diagrams etc., does anyone know what turns the heating elements on and what they're sharing a circuit with (if anything).
As they only warm the (tiny) nozzles I guess there's very little current draw anyway; nothing like a mirror requires.

Looking for results of testing those Ford mist type jets.
My prediction is that they'll aim too high :)
Hopefully they will be adjustable.

Watching this thread with interest

I'm very familiar with the geometry so, even though the Ford ones mount on the bonnet, I think they'll be pretty much spot on.
(Focus bonnet is quite sloped, unlike a D2)

And the Chinese ones I've ordered are advertised as adjustable. ;)

In terms of wiring the A8 D2 FL jets are 'always on' and are protected by 5A fuse.
The resistance and wattage will change depending on outside temperature.

Found that as well Andrew that some BMWs use the exact same connector and part number.

Thanks for that, and the diagram, clarifies a lot.

The connector (BMW 8366275-02 ) seems impossible to get at a "sensible" price so, unless someone has a better idea, I'll resort to "surgery" on my existing leads.

I always like to be able to put back the originals, so my plan is:
1. Buy a handful of 2-pin waterproof connectors in male/female pairs (available cheaply in UK).
2. Split the existing leads (near the connector) and insert a male-female pair in each.
3. Reconnect for normal use and wait for new nozzles to arrive from China.
4. Replace connector on the new nozzles with longer wires and the new type of connector.
5. Swap over to new nozzles by disconnecting old nozzles at the new split.

Slightly less tidy as each lead will now have a short "adapter" section in, but it will all be under the cover over the wiper motor. And no "empty" connectors.
Being lazy (and not good at crimping) I've ordered pre-wired connectors with reasonable tails on; they will just need soldering and a heat-shrink wrap.

Andrew, I came across another site that sells only connectors for cars. Their website is as follows:

https://www.automotive-connectors.com/

CAUTION: They have lots!

I’d simply ‘T’ into existing wiring for the new jets. Solder in new wires into existing ones.
So you will have both old connector and any new connector you can imagine to connect new stuff.
So that old and new connectors are not mutually exclusive and you will always be able to return to old jets if you want to.

For experiments I’d simply tee wires with naked ends and will do experiments without thinking too much about the fancy connectors.
When you decide about the right jets we can talk connectors.

Hope it makes sense :)
