Yep Kennie - I agree that your wiring is 'odd'.
But just checked mine and I have the red/white wire too - gawd only knows where that goes!! So you can ignore that one as being weird.
Do you have a Haynes or Bentley book with wiring diagrams (if not that would be a useful thing to buy) - the lack of the second ground (brown wire) is odd as I think that the PCB is used to 'pass on' the ground signal to another circuit so if it's not there then you might get other odd behaviour.
Looking at Bentley - if the Brown wire that you have is the Pin 5 wire then that goes to ground and you should be OK.
If the brown wire that you have is the Pin 2 wire then that doesn't go directly to ground (it passes on a ground source for the Emergency Flasher switch light and also the Rear Defog (if you have that)) - so if this is the only Brown that you have then you will experience very strange behaviour (as this may eventually find a ground but it will probably be via something else so it won't be a true ground and you'll have strange outcomes on the dash).
I bet there is a random brown wire floating around in the dash not connected to anything - go fishing!
And/or follow that green/yellow wire and find out where it goes - it maybe that someone has replaced your lost Brown ground with this wire for some reason...
