Maytag Washer Repair

Trying to repair my maytag washer. Have to replace my control panel and have 2 questions:
1.) How is the best way to access the plug module that connects the main wiring harness from the control panel to the washer motor? Do you have pull the top and front of the cabinet off to access this primary plug module.

2.) The 2 grey wires (#47 in wiring diagram) that come from the temp control board and connect on 2 leads above the water valves; does it matter which grey wire is connected to which side of the valve?

Here are the Service manual and its supplement.

No, it does not.
