Wiper motor electrical connector

Hi guys

I got a new front wiper motor as mine stops every now and again went to fit it in the lovely -3 c we currently have to find it has a different electrical connector. The old motor is two sided rectangle with a semi circle at the ends and the new motor connection is rectangular. There are four wires in the connection from the car yet only two on the new motor. It reckons to be the same part number but I stuck the old one on for the time being.

Are there any converters from old to new or do I have to make up a new connector to fit and which wires go where please

First picture is original motor connector the second is the new motor
