Washer pump problems

[Ska]

Hi All long time no post thing going on with me these days
Since the recent snow we've been blessed with my windscreen washer pump is not working. So far I have replaced both the pump and wiper and cruise control stalks on the steering (supplied by A8 parts naturally and hoped that it would revive my inactive CC system but it didn't) and check for any blockages in the jets and hoses (all clear) but the pump still doesn't work (nothing can be heard). From what I can see there is no electricity getting to the connector for the pump; broken wire perhaps? Thing is I've searched on Elsawin etc. and can't find the wiring diagram for this simplest of things but decisive for the MOT! The wires at the pump connector:
(1) Brown - earth,
(2) purple/black - 12v I guess?
(3) Brown /Blue - fluid level sensor

Thing is the wires on the steering connectors are different colours does any know where I can get a wiring diagram for this or better know where I should be looking for the open circuit as it disappears into the wing.
As always any help appreciated.
