just connect crocodile to positiv batery lead with extension cable - i just connected my bravo and took +12 from cigaret lighter (by smaller crocodile).
Let me know if you are able to connect with Airbag - in my Bravo 1,6 1998 no success
If you can't connect - good news for me (sorry for you), If you get connect then i have problem with cabel or ECU...
Good Luck!
