14. Extend the SIR deployment harness and adapter to the full length from the deployment

fixture or area.

IMPORTANT: On a dual stage inflator module, both connectors must be

attached to the deployment harness adapter. This will ensure
that both stage 1 and stage 2 of the deployment loops are
energized, regardless of the deployment state.

15. Connect the inflator module (1) to the adapter (2) on the SIR deployment harness (3).

16. Clear the area of people.

IMPORTANT:

The rapid expansion of gas involved with deploying an
inflator module is very loud. Notify all the people in the
immediate area that you intend to deploy the inflator
module.

When the inflator module deploys, the deployment
fixture may jump about 30 cm (1 ft) vertically. This is a
normal reaction of the inflator module due to the force of
the rapid expansion of gas inside the inflator module.

If you are deploying a dual stage inflator module with
stage 1 already deployed, the fixture may not move and
the noise may have been reduced.

18. Place a 12-volt minimum/2-amp minimum power source, such as a vehicle battery, near the

shorted end of the harness.

19. Connect the SIR deployment harness wires to the power source. Deployment of the inflator

module will occur when contact is made.
