Undoubtedly you will be flooded with replies telling you to turn on the ignition and find a hot wire by test light , then tap into it. DO NOT do this. Many systems in late cars run on specific resistances, tapping a second circuit into one of these lines will cause problems with the original systems.
I am not 100% sure on your car, but most BMW's use a negative trigger for the washer pump. This means the pump is supplied with full time positive when the ignition is on. I would suggest taking it from there.
