Gu4 rear aircon help

Hello, currently just fitted a factory rear aircon setup from a 05 gu4 into my 05 gu4, both zd30di manual. the front ac switch, rear ac lines and rear evap/blower box are all in and plugged in. im having trouble with the switch and blower fan switch on the rear of the console... im having to wire them in myself. ive found a wiring diagram that shows this rear switch however my switch has different colourd wires.. (6 pin)
2 blue for illumination, one black (earth) and the remaining green/yellow, white/black and orange/black and are different to the diagram i have. i believe they run under the drivers seat and up to the front and plug into the big grey plug behind the drivers kick panel. any help appreciated.. thanks
