engine frame chassi ground

[Chrisco]

My d21 hardbody has ground from battery to engine..,.battery to body and engine to body....is it important to have engine/body ground to the frame it self ??

Unless something else on the truck is grounded to the frame, I wouldn't worry about it.

Proper grounds are very important. You should always maintain clean & proper grounds (battery to frame, engine to frame & body to frame). There are many electrical components throughout all vehicles that use various (some use multiple) ground points. If one "leg" of the grounding circuit is compromised things can start acting winky and sometimes be difficult to diagnose. I've personally seen plenty of instances where people have gotten lost during diagnosis and just start throwing parts at a problem, only to find out later (through a thorough and proper diagnostics check) a simple broken, dirty or corroded ground was the culprit.
