pre facelift steering wheel with scoll

[yysnet]

My vectra is a 54 reg pre-facelift with CD30, from some reading i know this is a preface but full canbus one. It comes with 4 spoke steering wheel with no radio buttons.

I bought these buttons (from a 3 spoke steering wheel, as in picture) and wires in attempt to add scroll radio control to the car, unfortunately these buttons won't fit in 4 spoke steering wheel...

My question are:
a, is "6 buttons" radio control work with cid&CD70?
b, is there scroll version radio control in 4 spoke wheel?
c, is the CIM in my car a fullcan bus one? (or can i put a 3 spoke steering wheel with airbag in? and can airbag change be done by opcom or tech2)

Any reply is very much appreciated...

a: yes
b: yes
c: probaly yes to just use the 3 spoke airbag ect.

but the switches need tech2 to activate.

you need to be careful with the steering wheel as there are pre-facelift and facelift ones and the airbags are different shapes and have different wiring. yours being full canbus may need the facelift steering wheel but pop the airbag off (follow the how 2) http://www.vectra-c.com/forum/showthread.php?t=52674 and check the number of wires the facelift airbag has 2 I belive.

Thanks paulhb, i have taken off airbag, the wiring is a 2 connector with exactly same color shown in your link (the how2).

In this case i assumed this would be a direct replacement? (although i need to find somewhere to do tech2 activation)
