Electric windows thread again.

My electric windows have stopped working completely now. They use to be a bit iffy at times but if I took the fuse out and put it back in they would work fine for a few weeks. But now though they won't work at all not even with the key in the door. Does anyone know the pin out for the connector to the motor. I'm getting a 12v ignition feed but don't know what the others should do. And I have also got a body control unit but remember hearing it has to be of the same part number or higher to work. Is this right? And if it's lower can it be coded to work? Thanks.
