No, I said that the most it would do is arm the airbag. It could do a
lot less, like nothing.

Already did the tape over the hole thing. In fact, it works fairly well
with the right tape. I used insulating foam tape we have here at work.

I have been in electronics most of my life and I'm not really big on
cutting wires without a schematic. however...where is the damn dinger?? be
glad to cut it loose! or put tape tape tape on it!

I don't see a blue wire in the schematic. After looking at the schematic,
I find it possible that the system works the way you describe, but that's
not clear either. From what I've seen, it's possible that what you've
done also tells the air bag computer the seat belt is unbuckled. If
that's the case, it could result in improper or too forceful air bag
inflation in the event of a collision.

My recommendation is to do *nothing* to defeat or fool any of the safety
systems on the vehicle.

Furthermore, if you're driving your vehicle without wearing your seat
belt, you're foolish. That's why the alarm works the way it does-- to
make you put your seat belt on.

I couldn't agree more. My issue with the "dinger" is that when I am at a
drive through and NEED to remove my seatbelt to access my wallet, the thing
keeps going and going and going.

I am aware of the fact that this was changed on Sonata's built AFTER
9/15/05, but sadly mine was assembled in August and the computer (according
to my dealer) cannot be updated to reflect the changes made to reduce the
annoyance aspect of the "dinger".

Looking closer at the connector for the seat belt latch, there's switch
outputs there as well as the pretensioner - an explosive. Also, the seat
belt reminder is an output from the SRS module to the body control module.
That means that if you are able to kill the dinger at the seat belt latch,
you are causing the SRS module to believe that the seat belt is buckled when
it's not. It must change some mode of operation of the SRS system - what, I
don't know.
