Hi there CM
Yes it is possible, as a mate of mine did it recently to that same model for another CSr.
Pretty much he hardwired the motor to the switch he installed and threw most everything else out.
If you are not extremely comfortable with electrical workings (as I am not) then try and find an electrician to guide you or do it for you. Hope you can find one through friend of a friend or something.
Good luck, but please dont go playing with electrickery if you are unsure.
