Hey guys. Looking to do the big 3 wiring upgrade on my 93 3.0 truck and was wondering what everyone is doing ground wise. I can't seem to follow the 4 gauge factory ground wire to wherever it goes and the engine to chassis I couldn't even get a wrench on the block bolt. Has anyone else had this? Can I just add a ground somewhere else on the engine? Thanks for looking. This is a very helpful community and I love it.

I can't see how it could ever hurt to just add grounds unless they aren't routed correctly or there so many it becomes a serious addition of weight.

I usually slap a big cable from the alternator body to the battery & chassis, but I'm lazy

Found it and left stock.
Couldn't fight it off.
Stud spins so I'll mount this somewhere, probably on the metal inner fender near battery tray.
Haven't looked for these?
I don't plan on grounding anything to the bed.

Thanks for the input everyone. Grounded although to inner pass fender. I feel that should get the job done.
