What's this three wire connector in the trunk?

The 'trunk accessory connector'. Gives you B+ always on the Brown / Green, or will if F17 (10A) is present in the driver side fusebox.

Also ignition switched B+ on the White / Red if you fit the missing brown relay into the trunk fusebox.

Thank you! I'm debating leaving well enough alone and just riding without CATS in stiff mode. Instant suspension fault when suspension module fitted. Hoping it was just trunk wiring. Front CATS seem fine and i dont know how to get to the rear sensors

follow pinout diagram of the module plug and check the continuity etc. of the wiring to all dampers. I have had module play up and required replacement also.
