the 'point' of removing it without having to remove the steering wheel is that you wouldnt have to mess around with the airbag or clock spring, or having to mess around with the removal of the steering wheel....
Having done more CC installations than I care to remember - well into 3 figures - I think I'm reasonably competent to make comment so perhaps we'll need to agree to disagree.
Removing the steering wheel isn't difficult and doesn't involve any risk of damage to the Slip Ring or Air Bag if done properly. It's when you try to do something half cocked like take the Steering Controller apart that accidents happen.
its actually remarkably easier to pry out the circuit board than it is to remove the entire housing complete as it would otherwise involve disturbing the clock spring, both indicator stalks and all the airbag stuff thats involved therein...
Again that's a matter up for debate. Of course if you don't know what you are doing then it might appear easier to remove the Steering Controller in this way however as above it's not the correct way to do it and carries it's own risks.
You don't need to remove the Slip Ring or Indicator stalk to remove the steering controller so I fail to see your point here.
.removing the stalks isnt as easy as its made out in the guide!
Again with the correct tool and knowledge removing the Stalk is actually remarkably easy.
I can fit a CC from start finish in 15 minutes or less so I guess it's isn't that tricky!!
