I'm trying to add guage overlays to my 350z. It's an automatic touring 2003. In the video I'm using, the author points to a ground located in the interior of the Z. He has a manual transmission -- same year.
Here is the video. I've included the timestamp in the link at the moment that he starts referencing the ground location.
The problem is, this location doesn't exist on an automatic, but I'm assuming another ground location would have to exist somewhere. Anybody Know where it could be? or Where else I could hook up the overlays?
I've read that some hook it up to the radio, but I'm not entirely sure how to do that. Any tips would be great.

 

The metal dash structure under the dash cover should be a sufficient ground for what you're doing. Any bolt or screw that's metal to metal should work.

 

Thank you!! I chose the bolt holding the guage cluster down (I’m not an electrician, idk if this is good but it worked).

 

Glad you got it sorted!
