    Do not drive the cars any more than necessary until you get them fixed.

    You absolutely require those knock sensors. The engine's computer uses
    those in order to determine the maximum possible ignition spark advance
    that it can use without incurring engine damage.

    The engine's computer defaults to a "limp-home" spark map in the absence of
    knock sensor input, but I don't think you're meant to rely on this as a
    usable everyday setup.

    At this point you have nothing to lose by attempting a repair of the wiring
    itself. If an electrically clean enough connection can be made, you might
    be able to save the cost of new sensors.

    Or did the filthy little bastards damage the connectors themselves, or did
    they leave too little wiring to splice in new pieces?

    The rat problem needs fixed first then the wires. Rats just love that Honda
    wiring for some reason...
