HI i have fitted a new TD5 dash into my 300tdi and i have changed the speedo clocks but need to wire all my old switches to the Td5 ones. I have been looking and not to sure on how to do this. Do i need relays or does someone have the wiring sorted from the old switch to the new td5. I need the rear window wiper and wash, heated rear window ,Hazard,and Fog and where to get the plugs for the back of the td5 switches .Thanks
