The first step was to start tracing all the wires and rip out the old controller.
Essentially the motor in this one is a 3 wire AC motor, this uses a starter cap and a common neutral. One winding causes the motor to rotate CW the other CCW.

There is a kind of actuator that pulls in the a locking pin to engage the spin cycle when the motor is run CW.

Care must be taken with this as unlike most things that have been wired up form some reason the simpson 711 wires are all labled BUT one end of the wire will say one thing then when it enters the connector it will say something else the at the termination point it will be labeled somehting else again.

I decided to base my wiring on the plug labels.

A1 = Blue = Common Neutral wire for Motor, Spin Actuator and Water Pump.

A2 = White = Starter Capacitor and CCW Motor

A4 = Yellow = Spin Actuator

A5 = Red = Capacitor and CW Motor

A6 = Black = Water Pump

A7 = Purple = Spin Engaged Switch

A9 = Red = Spin Engaged Switch

White CV wire = Cold Water Valve
Black HV wire = Hot water valve

Purple = COM = Common Water Level Sensor

Black = NC = Normally Closed Water Level Sensor

Brown = NO = Normally Open Water Level Sensor

Inside there is also a microswitch for the lid however for the moment I have no bothered connecting this.
