You're questioning bizzare electrics AND Lucas in the same sentence?
My old mans S3 had elec washers, small chrome hex nut and black button?
As for wiring, black will be earth (of course), green power to motor, G/R should be either speed out to switch, all by memory. Speed is alternated by supplying power to the motor and feeding out to one of two different diameter rings on the large gear. Parking is achieve by the gap in the ring.
All from memory of resto on my S2 with S3 motor back in the 80's.

Only seems to be one fuse for everything. Gotta love the Poms idea of electrics. Don't know why I would be surprised after re-building and driving Cooper S rally cars in the 70's. How did they ever win the war? How did Lancasters even get off the ground let alone reach Germany?

Yes. Or just decide which speed you want to use. As may be the case if this is a 2 speed unit

SupporterHello from Brisbane.
The later S2A models also had this switch in the centre top of the instrument panel. The nozzle was in the centre of the bonnet and along with the washer bottle was likely to have been an Australia-only arrangement parts-wise.
Some people have suggested that their older S2As had a push plunger pump at the bottom of the dash. This may have been an aftermarket fitment rather than factory fitted. Before this stuff (washers, seatbelts, heaters) became mandatory it was not uncommon to fit aftermarket stuff sourced from accessory places like Repco.
Cheers,
Regarding parking, I have had alook and there is a points like arrangement in the plug housing that is operated by a plastic pin activated from a knob on the edge of the drive wheel. If that makes sense? If you remove the plastic cover just below the plug receptical all will be clear ☺

That's the single-speed with self-park wiring set-up. The later two-speed set-up has five wires - earth, self-park, permanent power, high and low. IIRC the extra wire is green with blue trace. Self-park is the brown/green wire. Permanent-power is green. Which leaves green/red as power on.
The wiper switch works totally differently too. The early square-motor switch turns the earth on and off, the later one turns the power on. I didn't use the rotary switch when I fitted two-speed wipers to my 2A, I modified a headlight switch (can't remember exactly how but there was an extra contact to fit and a wire looped from one terminal to another). Have a look at a Series3 or even Defender wiring diagram for confirmation of colours etc.
