One thing of the time.
I drove the W123 years ago and don't remember much, but the engine had vacuum kill switch, while ignition had vacuum valve build on it.
I doubt you moved that vacuum switch to Chilton?
For the sensors, it would be much easier to be precise with pictures.
Hydraulic pump was on wagons, is that what you had as donor?
