Hotpoint safety interlock wiring?

I've got a Hotpoint WD61 and needed to replace the Door Safety Interlock. Unfortunately, just as I pulled it out to see where the wires went they all came off!

I know the brown went to the "L" terminal, but I have red (thick) and black (thin) wires too, with empty terminals "C" and "N".

Can anyone tell me which one goes where?

Thanks!
