Further research has revealed that this header (C0289) is divided into two sections; one for K-bus connections and the other for panel and switch illumination.

It links 8 and 9.

The
K-bus connections on
C0289 are in pins 1 to 10 as follows:
1 = Immobilisation ECU
2 = LSM
3 = Instrument pack
4 = BCU
5 = link to connector
C0295 (more on this below)
6 = Sunroof ECU & rain sensor
7 = Parking distance control ECU
8 = link to 9
9 = link to 8
10 = Seat memory ECU
C0295 has a further six K-bus connections as follows:
15 = link from C0289
16 = CD auto changer
17 = Symphony radio/cassette unit
18 = Low line Navigation unit
19 = Not used on your car
20 = Not used on your car
By pursuing an error in RAVE I suspect that C0295 is a 20 pin rectangular blue header shown taped to C0289.
In theory it doesn't matter which WRY (K-bus) wires go where on C0289 so long as pins 8 & 9 are linked and they're only using pins 1 to 10.

Thanks for confirming. That shows that the K-bus is not working to the instrument pack or the BCU.
Regarding the loss of illumination on the instrument pack, this is fed on a RW wire from C0289 pin 15. Pins 11 to 14 should all have RW wires.
Confused?
