Float microswitch connection sequence?

In removing the bottom plate from my Indesit DG6100W I accidentally pulled the connectors off the float/microswitch that cuts out the machine if there is water in the bottom casing. As I do not have a manual I would be grateful if you could offer advice on reconnection. There are 3 connectors. A double wire pink, a double wire brown, and a single wire red.

many thanks
