This system supplies ground pulse from the switch to the factory relays. The correct
wires will measure some voltage on them when you are not pressing the lock/unlock
switch. Pressing the switch will cause the voltage on the correct wires to fall to zero
volts. Connect the lock/unlock wires from the unit to the described wires in the vehicle.
No additional parts should be required.
Type C: Reverse Polarity

to ground (less than 50 ohms) when the lock/unlock switch is not being pressed.
