According to this, the W126 uses a sine wave input to the speedo so whichever controller you use needs to have (or have a mode for) AC output.

I would suggest you look at the Dakota Digital SGI-100BT. They claim it can turn any input signal into any output signal plus it will run your Tacho as well.

Install the W126 temp gauge sender (not the temp sensor) on the engine, so that the Mercedes gauge is calibrated to read the correct temperature. Oil pressure gauge will need to be mounted on engine too and wired directly.
