Disco 2 D2 rear wiper motor on bench

I have a D2 rear door wiper motor on the bench which I am trying to activate.
I have a plug attached to the 3 pin socket with cable tails showing black, red/yellow and green/brown. I can't be sure that this plug is correct but it fits. Therefore, the colours on the car may be different.

Pins 2 & 3 (black & green/brown) are shorted so I assume this is negative and park, then red/yellow is positive.

Does anyone know how this motor is energised? Does it need a ground to the body? Does anyone have a schematic for the internal connections please?

There are also two pins between the motor itself and the rotation mech, I don't remember anything connected here but do you know if there should be?

Wiring diagram any use? Rear wiper is shown at the bottom.

Yeah, that's exactly what I needed to see. I should be able to work it out from that.
The two extra terminals I saw must be used then, even though I don't remember unplugging any more than the big, three pin plug.

Thank you.

Hi I could not help noticing you have been sent a wiring diagram for a LHD, see attached it's for a RHD car, there are some small differances and as your from Sunny Suffolk, I would think your in a RHD, like myself

Yes, I did notice it was LHD but hoped it wouldn't matter for the rear motor.
It was the connections internally that were useful but thanks for the RHD version, I'll save that.

Where are these drawings from? Rave or some other manual?
