So WTF? I disconnected the airbag module (the 1 with 2 big plugs), now it won't STOP beeping. It's just a constant 'tone' like when the door's open with the key in. I got sick of it so I just unplugged the buzzer. Good news is no more annoying door buzzer and the air bag light's not on anymore HAHAHAHAHA
Still confused as to why it wouldn't stop the tone....
FADI: I think with a little bondo and some elbow grease you'll be looking good. But then again, I can't see it from here soooo....
EDIT: For the record, being underneath the dash of a miata is quite possibly the most uncomfortable place I've ever been. Man that sucked.
