Hi, just wondering where do you get the ground for the sensors?
I was going to make a star ground where the MS is grounded. Is that ok?

If you're using a relay board, there's a specific ground for each sensor.
All of these are essentially tied into the same ground as the MS.
If you're making your own harness, yes ideally you should ground with the MS. The shorter the ground path from sensor to MS the less likely you'll see noise from various other electrics in the car.
Also, some people say that the engine is a preferential ground (vs the chassis)
