Yes, the good news is that Ford designed it with a current measurement feature to alter the alternator charging strategy which probably results in 0.1MPG better fuel economy which can add up over decades.
The bad news is it is more vulnerable to acid decay and very expensive to replace compared to a standard battery cable clamp. I don't know if you can get the separate pieces to DIY replace only the rotten parts or have to replace the whole thing.
See if you can find the part # on it somewhere. They might have used one design for a couple years then switched it on the '13 year models. Whether that matters I do not know. The '13-'16 part number looks like WC-96257
The best I can tell the whole thing is part # CB5Z14300A, but I don't know why it looks so different than the '13-16 so I might be having the same problem you are, not being able to find it. It looks like they also came out with newer revisions of it in ending not in "A" but rather "B" and "C", maybe "D" and so on by now.
Maybe it's not even the right part but there are large price fluctuations between these depending on where you buy them, ranging from about $165 to over $300 including shipping.
You might try calling a Ford dealer service center as they should have exploded parts diagrams with part #s. Hopefully they will at least tell you the part # you need for the whole thing OR if you can identify to them separate replaceable sections. If a section bolts on or plugs in then maybe it's replaceable as a separate part but I doubt you're going to be able to find just the clamp assembly without the cables.
Frankly since these vehicles aren't very old yet, I would use an online parts database or call around to local junkyards to find one that has an '11 or '12 Explorer and harvest as much of the cable assembly off of it that you need.
Once you get it installed, I would try using felt battery terminal protectors and a liberal coating of silicone grease over everything that showed corrosion on your original, trying to prolong the life of the repair.
Is there anything unique about your driving that you could attribute to such a high corrosion rate? My '14 doesn't have the tiniest bit of corrosion yet, but it is not driven on long trips so not as much chance to overcharge the battery for an extended period of time, and yet this newer smarter charging system Ford uses, should reduce that issue.
Lastly I do not know what would happen if you rewired it in a standard config where the cable just went from battery to alternator and starter, hood electrical junction box. In theory it would "probably" run and charge if they designed it with a little common sense, but it would probably also generate some fault code which nobody wants on their dash and (maybe?) cause emissions testing failure based on their polices rather than emissions.
All the above might lead you on a wild goose chase. I could not find any clear pictures with this assembly spread out and good indications of part #s to see what's what. That alone would make me pursue junkyard parts next, then with the high price of new, yeah junkyard all the way.
Please post your vehicle year/model/engine/(n)WD in help topics.
