Ok, got a 2000 Dodge ram 2500, 5.9L. There is a grounding nut on the firewall with 3 legs. One to ECM, another to engin block. Third one has broken connecter and I can't see where it goes. Anyone got a pics, or can tell me from experience. Can't really find it on schematic.

Thanks

 

They are for radio noise suppression and not "real" electrical grounds, hence they don't show up in the wiring diagram.
