Can't break the radar cable after it exits -- those cables have a lot of wires in them and that would make no sense.

If the manual includes the color coding of all the wires in the bundle, you might be able to carefully cut open the overall radar cable insulation at the dash, pull out a loop of the + positive power supply wire, cut it and splice in an on-off switch.
