There are a couple of foam pads up there. And should be four/five looms, all taped together/routed up the nearside A post...
1. Interior light.
2. Sunroof.
3. Autodimming Mirror.
4. Rain sensor (not fitted pre 2002my).
5. Vanity mirror lighting.
1 is the obvious one, pulling this gently should bring the others into view.
2 is a fair size, and identified by the heavier Red and Black wires, also has a Blue/Red wire to it. (this is a speed pulse if anyone fitting a posh video camera near by).
3 and 4 are taped together, earlier cars might have one squareish plug as they didn't have the auto wiper option, later cars have two flat plugs, one for the mirror (black iirc) and one for the rain sensor (grey iirc).
5 is a smaller plug which simply splits one power feed to both sun visors, be gentle.
Late non Elite facelifts had the option of auto dimming mirror and rain sensing wipers, along with 'ambient console lighting' Vectra C mirror is plug and play for this. I will deal with the rain sensor once I have sorted it... new screen needed for a start.
Earlier mirrors should be plug and play on earlier cars.
It might have a bearing, but I have only retrofitted this feature to '03 build cars, 2.2 CD/2.2 Sport/3.2 plod.
Two have had older Elite mirrors fitted, which required transfering pins from one plug type to another, and the third car has the later non motorised mirror (from a Vectra C) as would have been fitted at the factory.
