Hi,
I just removed all the SPI system from the car. There were a couple of wires I wasn't expecting. They branch off just after the main ECU plug. There was a red/white which was taped up and had a spade connector on the end. A green white wire I traced all the way to a grommet at the passenger side of the cabin. Ended up just cutting that.
I can't see these on the UK wiring diagrams, would they be for the air con system ? (my air con is removed).
