Need wiring orientation on heater water valve solenoid

[Kibokojoe]

The PO has broken the wiring connector (plug) on the solenoid and I am trying to troubleshoot it. I have three wires but they are hobbled onto the solenoid and may be out of order. Can anyone give me the proper orientation. The three wires are yellow/purple, yellow/green and yellow/brown. Does anyone know what each wire is connected to in the circuit?

the yellow/brown is probably the ground which is the center of the three pins, the other two could be figured out trial and error playing with the left and right temp controls
