Rear wiper motor Citroen berlingo?

I am replacing the motor on my 2002 berlingo. I have purchased a replacement but the electrical socket has only three connections and my old unit has four although one seems to be a blank can I rewire the new one or any idea where a three pin can be purchased from ? Thank you
