PASSKEY (VATS) INSTALLATION
(GM
only)
This FUEL SYSTEM shutdown anti-theft system is
based on a pellet (resistor) built into the steel shaft
of the ignition key. When the key is inserted into the
ignition switch, the VATS (vehicle anti-theft system)
computer reads the value of the resistor to make
sure that it matches the programmed code and then
turns on the fuel system so the vehicle can be started.
1. Locate two (2) wires in an ORANGE (or
sometimes BLACK) vinyl tube coming down
from the ignition switch. This tube will
contain two (2) WHITE 22 ga. wires or one
WHITE and one PURPLE wire.
2. Connect the YELLOW wire from the 791
bypass to the WHITE wire in the VATS
tube that shows voltage when the key is
turned to the ON or RUN position.
3. Connect the ORANGE wire securely to the
other WHITE or PURPLE wire that shows
ground with the key in the on or run position.
4. Connect the RED wire from the 791 bypass
to a co12 V supply.
5. Connect the WHITE wire from the 791
bypass to the vehicle ignition wire or the
large WHITE wire on the remote starter
connected to the PINK ignition wire on the
vehicle.
6. Connect the BLUE wire to the center WHITE
wire on remote starter modules with an
external relay harness or the WHITE wire
labeled “ignition negative” or the YELLOW
wire and sometimes the YELLOW WITH
BLACK STRIPE wire marked “security
bypass out”.
7. Attach the YELLOW WITH BLACK STRIPE
wire to the large YELLOW WITH BLACK
STRIPE wire on the remote starter that ...........
is connected to the starter/crank wire on .....the

Power up the bypass module then unplug the eight
wire harness from the unit. Attach the BLUE wire
from the eight wire harness to ground and plug the
eight wire harness back into the bypass module.
When the RED light illuminates, unplug the eight wire
harness and disconnect the BLUE wire from ground.
The bypass module is now ready to learn a new
code.
