Nissan Primastar/Nissan Traffic UCH-N3 information/pinout

[nogger1]

Hi all, i have a UCH-N3 module from a Nissan Primastar van which has been sent to me to look at. I believe it's the same module used in the Renault Traffic (pics attached). Complaint is wipers do not work at all but looking through the manual that i have it suggests that other than for timed /delayed wipers the normal wiper on/off circuit does not go through the UCH-N3 module. Just wondered if :

a: Anyone can confirm that
b: Anyone can identify what the relays in the picture below do (which functions they switch)
c: If anyone had the wiring diagram/pinout for the UCH-N3 module

On the long thin plug on this module i notice that Pin 1 is missing (looks corroded off) but talking to the owner he says that there isn't even a wire in the plug on pin 1 ??, anyone got any thoughts about that as well

Thanks in advance
