Let's play a game. ID this interior plug.
 

Stumped. What is this plugg for? Trying to figure out what it plugs into.

This is a 2006 A/T Touring convertible

Picture: Passenger side airbag area. One is for the airbag, but the other??

possibly satelite radio tuner??

got a better pic. something a lil further away that show the area as well.
im assuming its taken from underneath the dash!
Aux power/cig lighter plug?

Air bag ground! Did I win????

No I was wrong it is the ground to your mode door motor, air mix door motor, or intake door motor.
Now I have got to win something!

I found the plug to the power/cig lighter.. so that's not it.

The airbag has only one plug - yellow.

I can't figure out what else around that region requires plugging in.

The fact that there is some blue tape there (I didn't put this on) makes me wonder if Nissan intended it to be used for something. I'll grab another picture tomorrow.

What color is the wire?

thats for a something that is a optional on your car for example ipod interface or those bs you know? if it's taped with the other harness it's usually optional ones plug and play
