"The ignition is turned off by grounding the, black/yellow stripe, wire which you should find connected to one of the "M" terminals on the ignition switch. Depending on how your remote is set up, and exactly where the ignition switch and kill switch are located, the kill switch can be wired in slightly different ways.
In a side mount remote for instance, you could open up the box and simply cut or disconnect the wires to the kill switch. If cut, insulate any bare ends you leave in there.
If the switches are dash mounted, things might look different, but the concept is the same. The kill switch will be wired into that black/yellow wire somewhere, if not at the ignition switch.
If the wiring has been worked on over the years, the wire colors may be different."
