Exactly. Excellent products, and good customer service from my own experience at least. The EFI harness we sell is made for us by them.
One common area to mount one of their fuse panels is the driver's kick panel. But it's not the only place, if you're creative. But this is probably why the harnesses with the pre-wired smaller fuse panels are popular for Broncos. Lack of usable space...
For your application, nothing stands out as overly custom or odd that you'd need some extra help from a harness. Even the simpler Centech should have all you need.
Your gauges are going to be custom wired by yourself, unless Speed Hut has a pre-wired gauge harness you could utilize? Otherwise all you need is a common power in from the harness and individual sender wires. Both of which all the harnesses include.
Your alternator will have very little trouble with any harness. All of them (except the American Autowire) include at least one set of wires for use with a stock alternator. Which you can then utilize for your 3G.
The transmission only has the switch for the backup lamps, and here again all the harnesses have (usually extra long) two wires for the backup lamps that will interface with the NV3550 switch. If yours did not come with the chassis side connector, you can buy them pre-wired (

The EFI has the same needs from all harnesses. Constant power, switched power, and ground. All other stuff is stand-alone within the engine harness which is separate from your body/chassis harness. All harnesses have extra power and you can make your own grounds to enhance the engine-to-efi harness ground. Which you should anyway.
For lights, depends on how you want them wired. If switched, or constant, both AAW and Painless have a painful amount of extra circuits to use for anything you want.
Otherwise you could even create your own "light system" using a small fuse panel of four or five fuses with power from the key and from the battery, along with relays if any of the lights are extra powerful.
Pretty much doable with literally any and every harness with little to no extra work on your part.
Which is likely why you were not sure which one would be best. Because none of them are, and all of them are. Just like you've read in all those other threads.
Sounds like you're good to go then, other than still just deciding which!
Oh, and to your question about the AAW Severe Duty, as I've said before it's one of my favorite harnesses. But it's also the one that requires the installer to literally think about and map out everything. There is no one set place to mount the panel/box, and there is no one set route to go with any specific wire. You lay it out, think about it, think about it some more, bundle them the way you see fit, then start routing them around the Bronco. After you figured out where you want the box.
Oh, and then you pull some out and re-route them when, half-way through the job, you decided you found a better way!
That's not to scare anyone off of it. On the contrary, it's a bitchin' setup. But it's just by way of highlighting that it's not a plug-n-play, set-it-and-forget-it, one-and-done kind of a thing. You actually have a critical part in every aspect.
But once it's done... For those not familiar:

So if you are literally custom making every part of your rig, or are getting rid of the glove box, or you just want a different place to mount the fuses, this is your cup-o-tea.
If this is a first wiring job of any kind for someone, and the "custom" aspects of the vehicle are not too extensive, or if you've wired stuff but are just still slightly (or more than slightly) intimidated by wiring jobs, then one of the others is better.
In fact, for those the Centech is probably "the best" of them. If you put more weight on extra circuits for the unknowns, then AAW and Painless are "the best" for those. If you put more weight on original colors (like I do) then Painless is your only current mainstream source. I believe there are others out there, but I'm not familiar with them.
But I would not hesitate to recommend the big-three for anyone who's comfy with wiring. Simple? Centech. More stuff? AAW. More stuff and more stuff, and wire colors? Painless.
So, you like how we nailed it down for you, unlike those other threads?;D%)
