Here is the almost-final circuit.
If the user tries to start the car with the Forward/Neutral/Reverse switch in either Forward or Reverse, it beeps at them. The contactors will only engage in Nuetral.
Also the contactors will only engage or stay engaged if the Intertia switch, Charger lockout and Manual disconnect are all closed.
Text in brown is wiring within the 8 way cable from/to dash to motor controller. Text in blue indicates existing wires in the Vogue loom.The multiple wires from dash to engine bay is because the SW60 contactors are on the passenger side of the engine bay whereas the DC-DC relay and EV200 is on the driver side.
