rear wiper problem

Anyone? Got a defender N plate and when i got her the centre dash panel containing the cig lighter and rear wiper switch was diconnected.Got the cig lighter working but don't understand the other wiring for the wiper,i looked in the haynes manual and can relate the colours to what is there but don't know where they go on the back of the switch there is one in the middle of the switch and three round the outside each numbered.Also i have three left over after that which are red,green and black which i have no idea what they are for,any ideas?
