Which way do the wires go on Indisit tumble dryer model IDV65(uk)

Hi Paul, please could you assist me? I have an indisit tumble dryer model IDV65(uk). I have purchased a door lock assembly but I have no wiring map. the door assembley is marked up as It has three connections numbered 3,4,5. I have three wires grey, brown and pink/white. Which goes to which? im unable to test them as as I don't have the equipment and made the mistake of taking the tumble dry apart with out taking the picture of the wiring grrrr
