If you do have side airbags, DO NOT turn on your ignition whilst the airbags are disconnected. This will log an error "SRS Airbag Fault" on your computer which can only be cleared by Holden. I've made this mistake before...
If you're taking the seat out to put an amp in, you can turn on your stereo without turning the ignition on simply by hitting the ON button on the stereo (thanx Phreddy:thumbsup: ). It'll run for about an hour.
Oh, and like HsvPlayBoy said, disconnect the battery or better still, pull out the airbag fuse to prevent a costly and dangerous deployment of your airbags! :thumbsup:
