Meliss, you can get a new cord block here -

just open up the bottom of your controller, disconnect the cut wire from it and connect your controller to the new cord. It's very easy. Aside from the stitch cams, I'd say that all the other fiddly bits you have there went to the Singer machine that used to be in that cabinet but may be able to be used on the Wizard if it's a low shank machine.
