[QUOTE="maylar, post: 37817, member: 541144"] The frame is isolated from the body with rubber body mounts. There's no doubt bolts that make electrical connection somewhere, but in my opinion you're better off using the body sheet metal for your grounds. I have never seen factory wiring use the frame of a car for ANY electrical connection. You also need to have an appropriately sized wire from the battery negative to the body. Most cars only have a 10 gage wire for that. As long as this wire is big enough, studies have shown that there is almost zero difference using the car's body vs running a ground directly to the battery. [/QUOTE]
