I have a hard time choking down 800 bucks for a 20 dollar connector and an hour of labor.
Thinking of home-brewing one of these....
The only unique thing they have going on is the custom connector. Most of these panel mount industrial connectors are the other way around... a small piece that mounts in the panel hole, and a large plug (to provide strain relief to the cable that would otherwise be attached).
I'm thinking of taking one of these (more pins/combinations than the Revelco), and just running it fro the engine compartment to under the drivers seat, attaching the large cable side of the connector to the Jeep.

Then taking the smaller panel side of the connector, and cutting it down as small as possible, do the custom soldering to the pins as needed for my wiring scheme, and gluing a plastic cap over the solder side....
For my application, I'd very rarely want to actually remove the plug. Most of the time my Jeep sits in my garage watched over by cameras, and a Belgian Malinois with a hair trigger. The only time I'd want to use it would be when traveling... stopped at a hotel, or dining at a restaurant. 95+ percent of the time I want to not have to mess with it. I also would not want it visible.
Putting it under the drivers seat (maybe held out-of-sight with a magnet), would let me just leave it plugged in and "normal" until I have to leave the Jeep somewhere "sketchy".
I work in IT, so I have done a lot with network cabling in the past..... for an even more stealth looking solution, albeit with fewer "combinations" would be to throw a rj45 panel connector somewhere (glovebox, console, even right out in the open on the dash somewhere). and do the same thing, run a cable into the engine and re-wire some (would have to be low amp) circuit to the panel connector, and make a custom and VERY small rj45 plug to make the connections work.

Edit:
Plus installing it myself would mean that I'd know how the sausage was made. If I ever lost my plug or had a faulty electrical connection 50 miles from the pavement, I'd know how to fix it myself.
