I installed my new ddx7015 kenwood today, and when I turned my car on, the air bag warning light was flashing. Does anyone have any idea what could have caused this, and any ideas on how to fix it. Thanks in advance guys.

Also, I grounded the parking brake wire (to watch dvd's while moving). The screen was playing the movies before I tightened all the screws down, but after completing the install, the movies now don't show up on the screen at all. Guess I have to get back in there tomarrow. Any ideas?

 

The airbag warning light will come on if you disconnect any of the wires used for the airbag while the battery is still plugged in. The only ways to reset it are with a consult or with this method: https://g35driver.com/forums/faq-diy/13881-clear-airbag-warning-light.html

You probably disconnected the yellow wire attached to the glovebox. That one is for the airbag. If you warning light comes back on after clearing it, it means the problem still exists and you should have a professional look at it at that point.
