type C: reversing polarity system
Use these instructions if the power door lock switch has four or five heavy-gauge
wires. This type of switch has two outputs that rest at (-) ground.

NTT!! To interface with these systems, you must cut two switch leads. The
relays must duplicate the factory door lock switches’ operation. The master switch will
have one or two ground inputs, one (+)12V input, and two switch outputs going direct-
ly to the slave switch and through to the motors. These outputs rest at (-) ground. The
lock or unlock wire is switched to (+)12V, while the other wire is still grounded, thus
completing the circuit and powering the motor. This will disconnect the switch from the
motor before supplying the motor with (+)12V, avoiding sending (+)12V directly to (-)
ground.
It is critical to identify the proper wires and locate the master switch to interface prop-
erly. Locate wires that show voltage when the switch is moved to the lock or unlock
position. Cut one of the suspect wires and check operation of the locks from both
switches. If one switch loses all operation in both directions then you have cut one of
the correct wires and the switch that is entirely dead is the master switch. If both
switches still operate in any way and one or more door motors have stopped respond-
ing entirely, you have cut a motor lead. Reconnect it and continue to test for another
wire. Once both wires have been located and the master switch identified, cut both
wires and interface as described in the following paragraphs.

G!! If these wires are not connected properly, you will send (+)12V directly
to (-) ground, possibly damaging the alarm or the factory switch.
z
H2/1 WHITE/BLACK: Once both door lock wires are located and cut, connect
the white/black wire to the master switch side of the lock wire. The master switch
side will show (+)12V when activated and (-) ground at rest.
z
H2/2 GREEN/BLACK: Connect the green/black wire to the motor side of the
lock wire.
z
H2/3 VIOLET/BLACK and H2/4 VIOLET: These wires must be connected to con-
stant (+)12 volts (via a 15-amp fuse). The best connection point for these wires
is directly to the positive (+) battery post or an unfused source at the vehicle fuse-
box.
z
H2/5 BLUE/BLACK: Connect the blue/black wire to the motor side of the unlock
wire.
z
H2/6 BROWN/BLACK: Connect the brown/black wire to the master switch side
of the unlock wire. The master switch side will show (+)12V when activated and
(-) ground at rest.
