So, I finally got it done.
My car was originally only with the speedo cluster, but now I have the one with a tacho instead.
I had one problem, an that was that the fuel gauge worked inverted full=empty!
After wainting for some time, I got the in-tank pump/sensor from the donor car, and upon installing this everyting works fine now...
The sensor did send an inverted signal....!!!
Partnumbers were also different:
Original: 97BP-AA
New: 98BP-AA
So anyone doing this mod: get the tank unit also, as your own might not work properly with the new cluster...
