RR dash/speedo to rs2 speedo

[robo]

Hello everyone, run into bit of brick wall with some electrical work and I am looking for some help.
I just wondered if it's possible and how to hook up rs2 or s2 dash into RR quattro wiring? Also looking into possibilities of replacing dash with something like this.





Do you know anyone who could do this conversion??
Cheers

Audi uses the same wiring colour for speed signal in all cars, I think its purple with white trace.
When i wired up my UR with the aby in, it was a doddle once i had a wiring diagramme. Speed and water temp are easy its other bits that get you foxed!
Mine was 87 WR car loom, 90 RR dash and loom and 93 ABY to knitt together!
Must admit to smiling like a chery popped school boy when it started first go!
