Thread: D3 Wiring assistance required

One of the joys of buying a smashed car, is that towies frequently don't want to bother unclipping broken items, but just cut through the cables, or the smash has destroyed what was there and the item that was plugged in was left in a pile by the roadside.

I have 3 such dilemmas.

The first is the large circular connector for the LH headlamp. The cables have been cut through, which is not too much of an issue, as I have the both halves of the connector, and reconnecting the coloured wires is easy. However, there are 3 earths (blacks) for the dipped beam, main beam, sidelight and indicator, and if I'm reading the wiring diagram correctly, all 3 cables go to the same earth point C0564-1. So if my mental deduction is correct, it shouldn't matter which black is connected to which (all the same size wiring). Can someone confirm that that is the case, and it shouldn't cause any kind of issue with the canbus?
Electrics I am fine with, but knowing how sensitive the D3 is to dodgy bulbs and faults, I don't want to take any chances

The second is a connector that has been smashed in the impact. It's a green cable and a white cable, about 1mm thick, that comes out of the loom at the same point as the cables for the washer bottle. I can't find it on the wiring diagram anywhere, however, there seems to be a similar pair on the RH side which is a blue and white pair, but are just blanked off.
Are these connectors for some accessory that is not installed on my SE?

And finally the third one is another cut one - I think it's the sensor for the washer bottle. One pair of two thin cables in the washer pump region, black and red. Can someone kindly take a photo of said sensor in situ with it's connector, so that I can attempt to replace it and get the wiring around the right way?! It looks like it is a simple float activated switch, so in theory it shouldn't matter which way round the +ve and earth go. But looks can be deceiving!
Have hunted around on the net, but can find nothing in the way of pictures of the wiring connector, so any assistance gatefully received.

Thanks Graeme.

Anyone able to answer 2 or 3?
