I I M M P P O O R R T T A A N N T T ! ! If these wires are not connected properly, you will send (+)12V directly to (-)
ground, possibly damaging the alarm or the factory switch.
H2/C 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 the
master switch is operated to the lock position and (-) ground when the master switch is in the middle
position.
H2/D GREEN/BLACK - Connect the green/black wire to the other side of the lock wire. This is the
motor side of the lock wire and it goes to the lock motor through the slave switch.
H2/E VIOLET/BLACK - This wire must be connected to a constant (+)12 volts. The best connection
point for this wire is the constant (+)12V supply for the door lock switch, or directly to the positive
(+) battery post with a fuse at the battery post.
N N O O T T E E : : Except in GM cars with Retained Accessory Power (RAP). In these vehicles, the (+)12V feed to the
door lock switches is turned off if the doors are closed for any length of time.
N N O O T T E E : : Most direct-wired power lock systems require 20-30 amps of current to operate. Connecting the
violet/black wire to a poor source of voltage will keep the door locks from operating properly.
H2/F BROWN/BLACK - Connect the brown/black wire to the master switch side of the unlock wire.
The master switch side will show (+)12V when the master switch is in the unlock position and (-)
ground when the master switch is in the middle position.
H2/G BLUE/BLACK - Connect the blue/black wire to the other side of the unlock wire.
