Stumpeater, when you say "I have got it working by removing wire"
Are you saying that the dash light is on on your car until you remove the wire?
If so then I personally would say you have wired the switch correctly, and infact the switch has been tripped, to reset the switch, it is just a simple case of removing switch and pumping brake pedal a couple of times, then refitting switch.
No fluid should come out (if it does then there is a fault inside your master cylinder).

Forgive the rough diagram.

I've got mine working by removing the earth wire.Thanks.
