Well I searched and just found stuff about the light, I am going to be replacing my steering wheel in my 99 F-150 XLT and need to know how to disarm the airbag so it doesn't blow up in my face. Thanks for the help

 

1. WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.

Please refer to the appropriate vehicle shop manual to determine location of the front air bag sensors.

The side impact sensors (if equipped) are located at or near the base of the B-pillar.

To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).

Disconnect the battery ground cable and wait at least one minute. For additional information, refer to «Section 414-01».

Good luck!

 

In addition to the above.( right on the money)..Be sure you have adequately grounded yourself before starting the removal.Static Electricity can "fire" one of these off just as fast as normal voltages.
Merely sliding around on a seat can generate around 6KV(6000 volts) and this is enough to make it blow.
A truck is insulated from normal ground by the tires.
Im not sure of your "working environment" but you really need to make sure the frame of the truck is grounded to a confirmed electrical ground,and YOU are also attached to that ground path while working on the removal.
Where I work(Aircraft Radar Systems) we always use a wrist strap attached to the "3rd" prong of the electrical outlet.
