Hi Shaun, the black wires are the 12v supply from the fuse, the black/yellow is the feed to the lights and to the Engine ecu pin 30 and if automatic pin 36 of the autobox ecu, the brown/grey goes to the engine ecu pin 65 The connections to the engine ecu are only applicable to diesel engine models, the wiring to the switch might be a universal loom that is used in all models.
