forgetful

I pulled apart my machine to swap over new solonoids and now i cannot remember where the 2 earth wires reside. The model is f&p MW058U smartwash. Yes very old but in superb condition and it hasnt failed me yet. The customer care wont give me the wiring schematics saying i need a tech to wire it, but thats kinda a waste of good money just to seat 2 wires. I am looking for some help with locating the main power cord earth and the other earth from the grouping of wiring protruding from the right side next to the controller motor.
