The doorlock interface needed will depend upon the type of power doorlocking system
the vehicle is equipped with.
Note: The vehicle must have existing power doorlocks. The addition of a power
doorlock interface to a vehicle without power locks will not allow the RS unit to operate
the doorlocks. However, power doorlocks may be added to the vehicle in the form of
adding a model DS-2 actuator to each of the doors, along with a doorlock interface.
Green Wire:
Connection If Desired
The Green wire supplies a negative pulse for locking the vehicle's doors.
Light Blue Wire:
Connection If Desired
The Light Blue wire supplies a negative pulse for unlocking the vehicle's doors.
Note: Programmable Jumper
#
2 will allow the RS unit to emit a single or double
unlock pulse.

3 Wire Negative Pulse Systems
This power doorlock system is simplest of all doorlocking systems. A Negative
pulse system will have only three wires at the doorlock switch.
Examine the wires on the back of the doorlock switch:
1)
One wire will show Ground, regardless of the switch's position.
2)
One wire will show Ground only when the switch is pushed to "Lock".
3)
One wire will show Ground only when the switch is pushed to "Unlock".
Note: The lock & unlock wires coming out of the switch operate the vehicle’s
doorlock relays or a control unit with on-board relays, therefore the lock & unlock
wires will read voltage, up to 12 Volts, when the switch is at rest. The correct
connection point is between the switches and the relays.
The RS unit's Green & Light Blue wires can be connected directly to the vehicle’s
Negative pulse system since only a Negative pulse is required to operate the
vehicle’s on-board doorlocking relays.
Note: If the vehicle’s Negative pulse doorlocking system requires more than 250ma
Negative output, an optional interface must be used.

3 Wire Positive Pulse Systems
This doorlock system is similar to the 3 wire negative pulse system except the
doorlock switches provide 12 Volt pulses to operate the doorlock relays/control unit.
Examine the wires on the back of the doorlock switch:
1)
One wire will show 12 volts, regardless of the switch's position.
2)
One wire will show 12 volts only when the switch is pushed to "lock".
3)
One wire will show 12 volts only when the switch is pushed to "unlock".
Warning: The Positive pulse system can be confused with the 5-wire Reversing
Polarity system. This is because both systems emit 12 Volt pulses on the
“Lock” & “Unlock” wires when the vehicle’s switch is pressed respectively. It is
critical to identify which system is present since if 12 Volts are pulsed into a
Reversing polarity system, which rests at ground, a “Short” 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 the wires
show partial ground through the relay’s coils.
2)
The doorlock switch in a Reversing system will have 5 wires, while a Positive
pulse system the switch will have 3 wires.
3)
A
Positive pulse system uses factory relays or a control unit, a Reversing
system
does not.
