air bags light comes on

[jive358645]

Passenger dash light come on for air bag system only when someone seats. The on light on the clock come on at start but when, then light goes off. i am thinking it is SeatBelt Pretensioner but i am having second thoughts it is seat switch. i have already order a replacement seat belt assy. But i am now asking what someone else might think the problem is.
PS

i have not install the seat belt yet.

My guess would be the seat switch. But without the GM airbag codes stored in the ECM it’s just a guess.

You can usually fix that kid of issues using a zip-tie to join the conectors tight.
