windscreen wipers motor wiring

[frenchy]

Hi guys,
I have a Peugeot 406 1999 (S-reg) and my windscreen wiper motor died recently...
The one I wanted to replace had a 5 pins black connector...but a wrong ebay purchase got me a motor with a 4 pins Brown square connector.
Any idea if re-wiring possible??? (with the existng 5 wires circuit onto the 4 wires motor?)
Thanks in advance...
