OK I searched but surprisingly I found nothing, or maybe my search skill needs to improve.
But yes my question is simply that where is a good grounding location for P5? And how to make a grounding point? I was told to use just a nut and a bolt??
OK, is this a ok location? This is the back of the passenger side rear seat, it seems like there is no paint on the bolt so do i just unscrew it, wrap the ground wire around the bolt and tighten it?
