W124 diesels tachos are driven by a sensor that counts the teeth on the flywheel. There is a company that supply's a gizmo that converts this signal to a normal tacho signal. On 124's this is right at the bottom of the bell housing.
The 124 tooth counter can be fitted to the 606 crank position sensor hole, which is the one you are playing with. Some mods needed.
And yes, you either need to trim the crank or recess the flywheel to fit a lot of flywheels!
