Parts for Electrical Circuit
Wiring Ð Wire color
All wires have colorÐcoded insulation.
Wires belonging to a systemÕs main harness will have a
single color (1). Wires belonging to a systemÕs subcircuits
will have a colored stripe (2). Striped wires use the
following code to show wire size and colors.
Example: 0.5 G / R
Red (Stripe color)
Green (Base color)
Wire size (0.5 mm

Relay Specifications and Configurations
* Relay contact shown in the wiring diagram indicates condition before actuation.

SUPPLEMENTAL RESTRAINT SYSTEM9J±21
THROUGHOUT THIS ENTIRE DEPLOYMENT AND
DISPOSAL PROCEDURE.
9. Twist together one connector wire lead to one
deployment wire. The connection should be
mechanically secure.
10. Bend twisted connection made in the previous step
flat and wrap tightly with electrical tape to insulate and
secure.
11. Twist together, bend and tape the remaining
connector wire lead to the remaining deployment
wire.
12. Connect the deployment harness to the driver air bag
assembly, yellow 2±pin connector at the base of the
steering column. Route deployment harness out the
driver side of the vehicle.
WARNING: DEPLOYMENT WIRES SHALL REMAIN
SHORTED AND NOT BE CONNECTED TO A POWER
SOURCE UNTIL THE AIR BAG IS TO BE DEPLOYED.
THE AIR BAG ASSEMBLY WILL IMMEDIATELY
DEPLOY THE AIR BAG WHEN A POWER SOURCE IS
CONNECTED TO IT.
CONNECTING THE DEPLOYMENT WIRES TO THE
POWER SOURCE SHOULD ALWAYS BE THE FINAL
STEP IN THE AIR BAG ASSEMBLY DEPLOYMENT
PROCEDURE.
FAILURE TO FOLLOW PROCEDURES IN THE
ORDER LISTED COULD RESULT IN PERSONAL
INJURY.
13. Disconnect passenger air bag assembly, yellow 2±pin
connector located behind glove box assembly.
14. Cut the passenger air bag assembly harness
connector from the vehicle leaving at least 15 cm (six
inches) of wire at the connector.
15. Strip 13 mm (1/2 inch) of insulation from blue±white
and pink±blue wire lead of the connector.
16. Cut two 900 cm (30 feet) deployment wires from 0.8
mm
(18 gauge) or thicker multi±strand wire. These
wires will be used to fabricate the passenger
deployment harness.
17. Strip 13 mm (1/2 inch) of insulation from both ends of
the wires cut in the previous step.
18. Short the wires by twisting together one end from
each. Deployment wires shall remain shorted and not
be connected to a power source until the air bag is to
be deployed.
WARNING: FAILURE TO FOLLOW PROCEDURES IN
THE ORDER LISTED COULD RESULT IN PERSONAL
INJURY. NEVER CONNECT DEPLOYMENT WIRES
TO ANY POWER SOURCE BEFORE CONNECTING
DEPLOYMENT WIRES TO THE AIR BAG ASSEMBLY
LEADS. DEPLOYMENT WIRES SHALL REMAIN
SHORTED AND NOT BE CONNECTED TO A POWER
SOURCE UNTIL THE AIR BAG IS TO BE DEPLOYED.
THE AIR BAG ASSEMBLY WILL IMMEDIATELY
DEPLOY THE AIR BAG WHEN A POWER SOURCE IS
CONNECTED TO IT. WEAR SAFETY GLASSES

21. Twist together, bend and tape the remaining
connector wire lead to the remaining deployment
wire.
22. Connect the deployment harness to the passenger air
bag assembly, yellow 2±pin connector located behind
the glove box assembly. Route deployment harness
out the passenger side of the vehicle.

DEPLOYMENT PROCEDURE. FAILURE TO FOLLOW
PROCEDURES IN THE ORDER LISTED COULD
RESULT IN PERSONAL INJURY.
23. Verify that the inside of the vehicle and the area
surrounding the vehicle are clear of all people and
loose or flammable objects.
24. Stretch the driver and passenger deployment
harness to their full length.
25. Completely cover windshield area and front door
window openings with a drop cloth, blanket or similar
item. This reduces the possibility of injury due to
possible fragmentation of the vehicle's glass or
interior.
26. Notify all people in the immediate area that you intend
to deploy the air bags. The deployment will be
accompanied by a substantial noise which may
startle the uninformed.
27. Separate the two ends of the driver deployment
harness wires.

SOURCE UNTIL THE AIR BAG IS TO A POWER
SOURCE UNTIL THE AIR BAG IS TO BE DEPLOYED.
THE AIR BAG ASSEMBLY WILL IMMEDIATELY

DEPLOYMENT WIRES TO THE POWER SOURCE
SHOULD ALWAYS BE THE FINAL STEP IN THE AIR
BAG ASSEMBLY DEPLOYMENT PROCEDURE.
FAILURE TO FOLLOW PROCEDURES IN THE
ORDER LISTED COULD RESULT IN PERSONAL
INJURY.
NOTE: W h e n t h e a i r b a g deploys, the rapid gas
expansion will create a substantial noise. Notify all
people in the immediate area that you intend to deploy the
air bags.
