what all did you take apart? i habe had the passenger airbag, drivers air bag and dash light all disconnected and when i put back together never had a light come on. i changed the clock spring on my truck last year and my steering wheel locked on me so i turned on the ignition to turn my wheel at a better angle with the air bag disconnected. never had an issue. so many passenger airbags removed when doing sound system upgrades, all with never a light coming on. something has to be disconnected somewhere.
