Warning: The Positive pulse system can be confused with the 5-wire Reversing Polarity system. This
is because both systems show +12 Volt pulses on the “Lock” and “Unlock” wires when the vehicle’s
switch is pressed respectively. It is critical to identify which system is present, since if +12 Volts is pulsed
into a Reversing Polarity system, which rests at ground, a direct short circuit will occur.
3 main differences between a Positive pulse and a Reversing Polarity system:
1) In a Reversing system the Lock/Unlock wires
rest at ground, while in a Positive system
