You have the basic OE setup. Heavy guage ground from negative to the engine for starting and charging current. Lighter ground to the body/frame for current coming from lights and some accessories. Unless you are dealing with a C, its unibody so body and frame are welded together with good electrical connection between the two. There is sometimes a supplemental medium guage ground strap from engine to frame as backup. Beyond the possible engine-frame supplemental strap, I wouldn't sweat it.



Sorry I didn't clarify earlier but this is an 80 Ramcharger. Giving it a cursory thought, the only ground the body has is through the smaller gauge wire at the core support. I don't mind overkill, so I think I'll plan a 4 gauge from the rear of the block to the firewall and perhaps one from that point to the frame. Can't hurt, right?
