Type C: Reversing Polarity System - Viper 480XV Installation Manual

Type C: Reversing Polarity System

Use these instructions if the door lock motor/switch has four or five heavy-gauge wires. This type
of switch has two outputs that rest at (-) ground.
IMPORTANT! 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 directly 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 properly. 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 responding 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.
WARNING! If these wires are not connected properly, you will send (+)12V directly to
(-) ground, possibly damaging the alarm or the factory switch.
➤ ➤ 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.
➤ ➤ GREEN/BLACK: Connect the green/black wire to the motor side of the lock wire.
➤ ➤
VIOLET/BLACK and H2/4 VIOLET: These wires must be connected to constant (+)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 fusebox.
➤ ➤
BLUE/BLACK: Connect the blue/black wire to the motor side of the unlock wire.
➤ ➤
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.
