Black is ignition live, I usually connect to a black ign live in the footwell.
Brown is ground and I put that on a stud in the footwell.
Green is canbus and goes to the front fuse box (Rain Sensor)
I bought a whole set of this parts, with the wiring.
It has:
1. Light switch with "AUTO" position
2. Rear view mirror dimmable, with light sensor and ambi light led
3. Rain sensor
4. Plastic covers for sensor and mirror base
5. Whole wiring for it
So, I already fitted light switch and it works just as the old before.
I fitted new rear view mirror too.
I used old base (metal plate that is glued to windscreen).
Cleaned it and glued using Loctite 319.
Removing base is a bit pain and risk to break/crack windscreen.
So as its summer now and here the temperatures are almost 40 every day.
I parked the car on the sunlight for 3-4 hours.
And rotating the base left and right it came off in a minute.
Also the base had to be moved up, closer to the roof, so that plastic covers can be fitted properly and hide all the cables.
So, now I am on wiring.
Auto dimming mirror has 2 wires.
Brown and black.
So, I suppose brown is + and black is -
Rain sensor has 3 wires.
Brown, black and green.
I suppose brown is + and black is - and the green is some sort of signal.
Can someone please help me with this?
I would like to make rain sensor functional.
So need to know where the wires ending too.
In which connector they go?
As I can see, they go down the A pillar in the footwell.
Any advise and suggestion are welcome.

OK, thank you for information.
I will make the same for mirror.
As for the rain sensor, I figured out that when I moved mirror base upwards.
The sensor will be partially covered by black tint (which is behind the mirror base).
I can feel that under my nail, so its on the surface of glass.
Is there any way to remove it?
Nitro thinner or some solvent?
One more info.
I just cut out those wires I will need for rain sensor and mirror.
I figured out that all the brown wires are joined together with one main (thicker).
Here is picture.
Same for the blacks, but its strange. Two wires are coming in and two are going out.
Here is a picture.
Around this was heavy insulation tape with fabric in it.
I will all join as it was, without not needed wires.
I will solder them together and insulate with two layers of thermal shrink tube
Use them all. If you remove some, you could well find out that the single wires you leave cannot safely carry enough current. In that case, you could get a fire starting.
Mine astra is LHD, so where to find ign live in the footwell?
On the metal rod below passanger airbag?
Could someone just upload a picture of the cables?
OK, base for mirror fitted, then mirror fitted on it.
Cables run down by right A pillar and ended behind the glovebox (black and brown (+ and -).
Green cable from rain sensor run down by left A pillar (can bus).
Now I have a problem and I believe I will not be able to fit rain sensor.
Reason, need to remove some of the black dots (laminate on the windscreen), but it seems to be impossible.
As i found out till now, there are two types of black dots on thw windshields.
One are on top of the glass and the orher are in the glass.
Mine are on top of the glass, actually on inner side if you are looking from the car.
I tried with sharp pocket knife, but no sucess.
So, does anyone has any idea about this.
I need to scrap and clean (make transparent a 1-1.5cm of dots)?

And other problem, where take power from?
From lighter?
From blower? (dont like it).
I am also planing to put in the Car DVR PowerBox (permanent power for Car DVR).
It converts 12V to 5V 2A, and cuts off power if battery power drops below 11.6V
Where to take + and - for it?

Mystery about wiring solved.
Thank to ArdenVXRJay @ www.vxronline.co.uk/forum/
Now just need two of this and get to work.
All connected and working.
Now have to find piece of vinyl to cover up space behind mirror base.
