Q:  The start kill does not work.

A:  The new start kill switch only has four wires.  The old unit has six
    wires.  Due to this change, the control module's main power wire
    (red with fuse) must be connected direct to the battery.  This is due
    to the momentary loss of power at the fuse panel or any bus line
    remotely connected to the fuse panel during start up.  The voltage
    drop at the fuse panel can, in most instances, be down to less than
    10V DC.  The alarm is designed to work within the voltage range of
    11V to 16V DC.  Anytime the voltage drops below the range limit, the
    alarm resets itself.  Consequently, the voltage drop to the control
    module also affects the start kill switch.  When the coil is without
    power, the contacts inside the relay are open.  Only when there is
    11V DC or more on the yellow and black wires from the control module
    are the contacts on the start kill relay closed and only then can the
    vehicle be started.
