Brown two pin connector by the left wheel
 

Any idea where this brown connector goes to? I know the long cable goes to the Left DRL, but no clue where the brown connector goes to at the bottom left corner of the picture. anyone knows?

Your horns still working? Just wondering.

Yes both of them. This connector hangs by the DRL black connector but it is a little shorter

Kinda hard to tell. Did you mess with the windshield washer and reservoir? That's the only thing I can think of at the moment, but that's on the passenger side. How about impact sensors for the airbag?

If nobody comes up with an answer, try the FSM.

I believe it plugs into the black box that hangs right underneath your horn. I'm not sure exactly what it's called (impact sensor maybe?) but it's a familiar sight from having my bumper off so much.

Its "above" the horn sorry. Picture is sideways upload is acting stupid but it's on the far left of the picture almost exactly mid way

I dont know what that little box is.. almost looks like a piezo buzzer

Ditto. Pretty much a piezo airbag sensor.

So I suppose my guess was pretty good haha hope the OP got it figured out though!

Piezo buzzer? This cable still not finding a home. Lol if anybody can get me a part number or a picture of where it connects to that would be appreciated, so far it is not giving me any ecm or airbag code.

Great i just saw the upside down pic!! Will stop by the dealer with this info!! Thanks guys!!! For getting another Z on the road
