    Hi All,

    I'm looking to build a circuit to enable me to switch a relay based on when 12volts passes through a wire.
    BUT I can't cut into the wire.

    It's an automotive project to add a trailer board to a car without cutting into the wires, I have CAN Bus based electrics and warning stickers forbidding me to cut into wires.
    It's a project really to see if it's possible, I heard of a fibre optics similar solution, suction couplers and the like which I'm not keen on.

    Any pointer would be appreciated, Hall effect? or some sensors that could start me off in the right direction.


    Cheers
    Rob
