How on earth do I get into a Dyson DCO5 (2)?

This question is related to an earler one on the same subject.

Can you give more help on how to remove the yellow on/off & rewind cable tabs? in order to get at the last two screws. I have gotten inside by pulling off the two wheels as Phil described but it would be a much better solution to do as Gordon says as getting off the wheels demands a lot of unpleasnt force on the yellow plugs that hold them on.

Cheers
