I have an 05 350z and have a blinking airbag light on the dash. I put it in diagnostic mode and found it's related to the driver side module. I look under the seat expecting to see yellow or orange connectors but they're all white and one lone grey connector.

Where is the connector exactly located? Image attached of mine.

P.S. Wtf is up with the electrical tape???

 

After reading the SRS manual some more it sounds like I have to take apart the steering wheel. Fun times.

 

I've got this same issue. I remember reading years ago that watere hitting a sensor somewhere could trigger the light on the dash...

Anyhow, if you find the solution on how to fix please post.
