It should be:
Blue: Signal
White: Ground
2xBlack: Heater 12V
nice one mate, you have any idea which wires are which then on the c20let loom?
Sorry mate, no idea on the LET.
The 12v is easy if you have a multimeter - this should be live when the ignition is on and when the engine is running.
Ground should be similarly simple too, leaving you the signal wire :)
