This was on Don's roll bar post. I thought it'll be a good idea to post it here.
1) car off, all belts unbuckled, parking brake on
2) turn key to on position. you will see seat belt warning light light up red
3) after 1 min, light will go off, now you must buckle and then unbuckle seatbelt you want to disable warning for 9 times exactly and finish doing this within 50 seconds of the light going off
4) airbag light will go on for 3 seconds or so
5) after it goes off, buckle then unbuckle seatbelt again 1 time
6) light will flash, seatbelt warning disabled.
