harness confusion re airbag

[omodos]

This has started to really confuse me…I was looking for the harness/squib connectors that attach to steering wheel airbag on a nov 2004 e53 3.0d, what is listed on realoem and even at dealers does not correspond to what is installed on vehicle(vehicle is factory spec) my car has the 04 and sports steering wheel shown in first pic

Realoem says part 5 (adapter wire f airbag module, part no 32306766855) is the part whereas this does not exist on the vehicle, what does exist if you look at second diag (the 01-03 sports steering wheel) is a cable resembling part number4 (connecting line, airbag/slip ring part number 32301097246)

What is going on? I cannot get a definitive answer from anywhwere, including bmw uk, Cyprus and even Germany….neither can I find 32306766855 if I google it…hmmm
