When running wires inside the vehicle to
the module location, use either tape or
split loom tubing to cover and route the
red wire to the firewall. Always use either
existing grommets or if a new hole is
needed to be drilled protect the wire
from chaffing by installing a proper size
grommet.

3. Mount the shock sensor:

Mount the dual stage shock sensor using
a wire tie to the steering column, or thick
wire harness, or even a dash brace. Plug
the harness into the shock sensor, then
plug the other end into the 4 pin white
connector on the module. Make sure that
the adjustment screw is accessible for
later testing and adjustment. Do Not
mount sensor under the hood!

4. Install the Status
Indicator (LED):

Locate a suitable place for the status indi-
cator (LED), drill the appropriate size
hole (7/16”). Make sure there is enough
depth for the LED to fit all the way in,
and can be easily seen from outside the
vehicle. Carefully run the LED and 2 pin
red connector and wire harness to the
module and plug into the matching red
two pin connector on the module. Push
the LED into the hole, it should fit snugly.

5. Install the Valet/
Override Switch:

Mount the valet/override switch in a hid-

den location, but that can still be found by
the customer for programming and emer-
gency override situations. Run the 2 pin
blue connector and wire harness to the
module and plug into the matching blue 2
pin connector on the module.

6. Connect Starter
Disable Relay:

Using a volt/ohm meter locate the starter
wire (normally a heavier gauge wire) off
of the ignition switch.The meter will read
12V+ only during cranking.When the
starter wire has been located, cut the
wire, the vehicle should not be able to
start now. Cut the brown starter disable
wire (with the two female connectors).
Connect one side to the vehicle’s starter
wire, then plug to either .25 male spade
lugs on the module.There is no polarity.
Connect the other brown wire to the
other starter wire off of the ignition
switch. Plug the brown wire to the other
.25 male spade lug on the module.The
car should now start.

7. Connect the Illuminated
Entry Output: Black/White
wires on main harness

If the vehicle has a negative door switch,
connect one of the two black/white wires
from the main harness to ground.
Connect the second black/white wire to
the green wire, also from the main har-
ness (negative door input). If the vehicle
