I've been having grounding trouble since my new Pioneer head-unit install. I first tried the bar where the center console screws into, but that had noise in it...

Where is the best place behind the dash, in a 4th gen, to ground a headunit to?

Thanks.

 

why not the ground from the oem harness.....

 

OEM harness is even worse...

 

how did you ground it to the center console thing? did you use an o-ring or some kind of connector? or did you just screw it in?

 

I used a spade terminal

 

Well, where did you guys ground your head units?

 

It is Non existant
