You may have something here Vinnie. From the MGR wiring diagram it appears that the black connector has 4 wires. With this connected to the motor, the wipers switched off and the car's systems "asleep", is it possible to measure a voltage between the red/light green wire and earth (the black wire)?

If this is impractical I have a plan B.
