Before handling any part of the air bag system, remove the negative battery cable(s) to passively stop the air bags from working, then wait two minutes so the air bag capacitor discharges and can't deploy unexpectedly. Step: Pull the negative battery cable from the battery terminal. Then, unscrew the switch-to-steering wheel mounting screws and separate the switch from the assembly, after that remove the connector connected to the switch. To install the switch, insert the electrical connector first, then put the switch in place and anchor it with the mounting screws tightly (3 Nm Equals 26 in. lbs. or 2 in. lbs.) Make sure you reinstall the air bag module as directed and attach the negative battery cable(s) before you begin work.
