Rewiring the knee control is pretty easy. I just got a piece of lamp cord and replaced the old wires. I am out of ring connectors at the moment so I just made a loop by wrapping the wire ends around the thread spool holders on the sewing machine. (when I get some ring connectors I will redo the connections) Then I did the same to the 3 pin connector that the power plugs into. Rewiring the light and motor was more complicated.
This is what my knee controller looks like.
