All you need is a radio to see the difference that chokes make!  Foiling your wires will cut out electric field. If you are using a 12vDC linear power supply you don't get an electric field".  You do get dirt from your devices. You can stop some of that with ferrite chokes.  Put at device end to start. This will stop your wire broadcasting. Attach more at 10P each until you are comfortable!
