Wiring diagram - ground locations
 

Figured this is as good of a place as any:

Does anyone have a list of the factory ground points? I've noticed that the "whine" that I have (and have learned to deal with) only happens when the car is in motion above a few MPH. It also seems to be in line with when the navi disables buttons because the car is in motion. I know several people have mentioned that the "whine" might be because of a faulty ground, so I'm looking specifically for any grounding points related to the audio system speed sensor.

Thanks!!!

There are just to many to point out.....really is. Even with me tearing down over 30 z's I still do not know where they all are. The service manual may help you.

Is this with a factory sound system or aftermarket? Pioneer?

09 Touring w/ factory nav.

Than I would go to the dealer and make them find the problem. Grounding issues is not a fun on especially for alternator wine.

Hahahaha... Dealer...

My warranty has been out for over a year lol!!!

Just thought I'd had a breakthrough on the famous high pitched noise issue from long ago...

Got a link to the service manual?

Nice link, thanks.:tiphat:
