Help with wipeswitch wire's

Hi i need some help, can some one please till me what wires go were on the wiper switch, i won one on Egay and when it arived the wires were off:doh:, as my 110 never had one as it come in bits and most of the cab was robbed out, it has the 5 wire loom but switch has 6 wires in the plug and switch is numbered 1 to 8, the reg/green and brown/green have jumpers, i have worked out the washer wires, i have the landrove manuals but they just show the stearing colum number 35, starting to get in to a dead end here!!
its a 1989/F 110 utility 3 door, it has the post 86 loom and the J14/J19 diesel interface/sub loom on to that, its now 200tdi on to a HP22-ZF4 auto box and the list of parts that go's on for a long way, i just need to sort this and retrim the seats and its mot time!!
Thanks in advance for any help.
