I am looking for help. I accidently pulled a little too hard tracing the wire on the flow switch to the circuit board and yanked the plug right off the circuit board before I got to see the orientation of the wires. Unfortunately, it seems like the plug on this flow switch is the the same size as the original. Being much smaller it can fit on the circuit board in either orientation. So I am hoping someone here can tell me the correct orientation for the P10 Flow Switch plug wires. White above black or black above white? See images:
