They're just called "marine battery terminals" like these:

They come in brass too, but apparently those have issues with breaking. I've never had to replace any of them on either truck.
Smother them in grease once installed and you'll have corrosion free bat terminals for a decade........or at least between battery changes haha.

Marine could be a key word I didn't use. These never showed up. I need to rewire batteries on the boat, have plenty of marine grade cables. Also have a crappy Auto Zone terminal on driver side positive in F-350. There is an extra cable for hoist pump, and I don't like how it was done by previous owner. May just go ahead and replace everything altogether over the winter while this truck is not being used often.

Matt, i got the positive cable for my 88 from NAPA. just be warned, they aint cheap. i believe it was $174.
i know it is a bit out of your way, but Bridge Auto/NAPA on RT34 in Cheesquake, a few stores away from Big Eds steakhouse still has people that know what they are doing.
the one on 34 in Matawan is a joke.

Thanks, Tom. The Matawan store is a joke, you are right.

That cable you posted is what you need, yes.

ran a wire from driver side positive terminal and connected to passenger side positive terminal and disconnected ground cable from passenger side battery and it read 12.8 volts.

25F out yesterday. Both trucks started, sitting outside, neither plugged in. After 10+ second glow time, in 1 second flat of crank time. Yes, 1 second (I'm not sure you could have fully said "one Mississippi", if so, there's no way you would have gotten anything else said after). They literally started identically. I started them back to back to move them around. They were both hard starting again recently, and just needed some new glow plugs.

When everything is working as it should; no resistance in 30 year old+ battery cables, a good starter, good IP/injectors, and set of motorcfraft GP w/ a good working controller; you'll have the easiest starting engine you've ever owned.

Went to start up my little beater Honda 4cyl car with an oversized battery, (and a starter I replaced just a couple years ago) and I had to wait 4........yes, 4 full seconds of crank time before it fired up. Still just fine and normal. Nothing wrong with it, in such cold temps, but man, it doesn't compare to a diesel in tip top shape with glow plugs to assist you.

Battery cables are large and pricey for these trucks..............but believe me when I tell you, your probably not going to miss the money they cost you, I'll put it that way.
