Your talking about zinc plates as sacrificial anodes? That is what is used to prevent electrolytic corrosion on boats. I would think that Toyota would be aware of the need for ground to make that work. Besides electrolytic corrosion isn't the problem we are battling, but instead normal weathering and corrosion from salt contamination.
So it actually looks like First and Second Gens were supplied with a DC power source to act as sacrificial anodes on the outside of ships that transported other Toyotas. It was a suicide mission like Kamikaze. Very honorable. The whole electronic rust protection system was a scam for automobiles and was likely a dealer ad on to make more $$$. Like selling sh*t on a shingle.
If you read what he's doing, it is a restoration, not a crawler. Not everybody has to sas everything to feel like a real truck owner. He has an insanely clean first gen truck, too
His resto is sick, I just need a solid axle in front to make me feel like a big boy. Plus, solid axles provide a good place to catch smaller road kill such as raccoons and possum. I hear solid axles also attract loose women due to their
