Further to my posts on the electric dipping mirror were nobody appears to know what wire does what does any one know what the sensor does on the front of the mirror?

But what does it do?

Thank you,I will not bother with that wire then if I can work out which one it is!

Just been playing with the wiring on the mirror and used the black wire as an earth pink to live and grey to reverse might not be right but seems to work,does anyone know any different?

I managed to check the wiring on my friends freelander and the wiring on the mirror side of the connecter does not match the colours of the wires from the loom so if anybody is interested in the wiring and wants to retro fit a mirror were no wiring is pre-installed the colours are black is earth,White is ignition live,grey to reverse light and yellow( which I did not use )to hevac.
