UNIVERSAL
BYPASS
MODULE
Used when installing a
remote starter on any
vehicle equipped with
a factory anti-theft
system.
MODEL 791P

791 UNIVERSAL BYPASS MODULE
The Model 791 interface module is used when
installing remote start products in any vehicle equipped
with an anti-theft system including BMW, Audi, Volvo
and Mercedes. The Ford PATS, GMs PK3, VATS,
Passlock I, Passlock II or any other transponder
systems. This model allows easy interfacing while
maintaining the OEM system’s integrity. The Model
791 has no affect on factory anti-theft system when
the remote start is not in use. The factory anti-theft
system remains fully functional.
BEFORE YOU BEGIN
Refer to your system’s instruction manual, and
our website at www.bulldogsecurity.com, to
determine what type of anti-theft system your
vehicle is equipped with.
It will be necessary to open the 791 Module to remove
the wiring harness before installation.To do so, simply
insert a straight shank screwdriver into the two wide
slot holes in the bottom of the module. Plug the wiring
harness into the module. NOTE: If you are using
the 791 Module as a transponder bypass you
must insert a spare ignition key inside the black
ribbon coil (as illustrated on page 9) then snap
both halves of the module back together. This
key must be a key that starts the vehicle.

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 constant +12 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

To Erase the Memory
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.

PASSLOCK I INSTALLATION
(GM only)
This FUEL SYSTEM shutdown anti-theft system is
based on a resistor built into the ignition switch. The
system is recognized by a security light on the
dashboard cluster.
1. Locate the harness coming from the ignition
switch inside, find the three small wires
YELLOW, BLACK and WHITE or (1)
BLACK WITH WHITE STRIPE wire and
(2) BLACK wires.
2. If your vehicle has the BLACK WITH
WHITE STRIPE wire and two (2) BLACK
wires, you will need to test the two (2)
BLACK wires WITH THE IGNITION KEY IN
THE ON OR RUN POSITION. Test both of
these wires, one will show ground and the
other will show positive.
3. Attach the YELLOW wire from the 791
bypass to the Passlock wire that shows a
positive.
4. Attach the ORANGE wire from the 791
bypass to the wire that shows a ground.
5. Attach the RED wire to a constant +12V
supply.
6. Attach the VIOLET wire to the bulb check
wire. A 22 ga. BLACK wire in slot “D” or
“E” coming from the ignition switch on the
left hand side of the steering column located
along with the heavy RED power wires in
the ignition switch harness. This wire will
test negative only during cranking.
7. 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”.
10..........Wait until the L.E.D. light on the 791 goes
