I didn't mention it in those threads cause I thought it would probably be obvious, but the wires are wrapped with a bit of black fiber tape to keep them secured... you'll need to unwrap the tape, which is no biggy.

Apparently the new version supports AEB ad ACC, according to Redarc support, but no info about how to connect in manual (other than to connect the red wire "To Vehicle Brake Light Trigger"): TOW-PRO® ELITE (EBRH-ACCV3-NA) TRAILER BRAKE CONTROLLER : https://cdn.shopify.com/s/files/1/2204/8993/files/REDARC_Tow-Pro_Elite_V3_NA.pdf?v=1607997414 (see page 10)

Technically any aftermarket brake controller will work with the AEB and ACC if you tie it into the brake light circuit instead of the wire Ford goves you under the dash. The wire under the dash only gives a signal from the brake pedal. If you tie into the brake lights AED/ACC will trigger the brake controller too. Just need to find where to tie in without running a wire back to the tailight or the high mounted stop light. Ford did it that way to avoid splicing into an existing wire bundle and used a extra module to isolate it from the existing curcuit to prevent errors. Probably some safety regulation CYA also, fromissing it on the original design.

From what it says in there, it doesn't sound like they've done anything to add support for AEB and ACC, other than suggest that it's possible to wire it up differently to make it compatible (which is what Ford's done by packing in the Lumen module which is used as the brake light trigger page 10 refers to). In theory you could use that Lumen module with any old brake controller to add support for AEB and ACC, since all it does is say 'hey the brake lights are on now, you can do your thing'.
In Australia, RedArc has their own addon that adds support for AEB and ACC, but it involves running wires under the truck all the way to the 7pin trailer connector to get the brake light signal :/

what am I missing? What else is there to do other than get the signal?

Getting the signal is the tricky part - Ford's prewiring only gives you a brake pedal signal instead of a brake light signal.
The problem is that to get a brake light signal you need the Lumen module, which taps into the brake & turn signal wiring, and translates that into something that a brake controller can use.
What makes the install difficult isn't the module itself, it's that Ford decided that the best (or safest?) place to tap into the brake & turn signal wiring was in the headliner by the rear window, instead of somewhere under the dash.
If Ford is now providing a newer RedArc unit (v3 instead of v2), then that's neat, but it doesn't to change anything at all. It would appear that they still require the use of the Lumen module, and still think the best place to connect it is in the headliner by the rear window.

I guess I'm still missing something. This thread ( CHMSL (3rd brake light) Strobe module | Page 2 | 2019+ Ford Ranger and Raptor Forum (5th Generation) - Ranger5G.com ) says you can get the CHSML signal without going to rear of cab headliner.
What I'm still missing is "what is this lumen thingy and why do I need it?" From what I understand (probably wrong), is that the CHMSL connection is to pickup the signal that turns on the brake light when AEB or ACC activate brakes (no signal from brake pedal so ford's hack is to pick up the signal that turns on the actual light).
Why do I need both (brake light and brake pedal)? The CHMSL is going to come on regardless how the brakes are activated, so why can't I just connect ONLY this, and what is this lumen thingy doing?

The Lumen module reads the CHMSL wire and makes a new 12V/0V signal that the brake controller can understand. The CHMSL signal as-is, is not compatible with a brake controller. Doesn't matter where you get the CHMSL signal from, it will need to be adapted into something a brake controller can use.
You don't need both brake pedal and brake light signal. Just brake light signal (or you can settle for brake pedal signal in non-AEB/non-ACC vehicles).

Awesome. Now it makes sense!

I have had my Redarc Pro for some time now & have not installed as of yet. Going thru this thread I have come up with an alternative mount. Still easy to use plus removable if need be. I do not have it wired up yet as the need is not there yet. I have mulled this around for some time as I was in no rush to get this installed. The mount is a simple L bracket that I reshaped & installed a plastic face to & then paint. Other than rounding off some of the pointed corners & bending I did nothing else to it. The bracket fits perfectly in both notches of the dash & the console by just sliding it in. I believe I can live with it in this location.

Yesterday installed my V3 module and it took 2 hours including fishing the wire to third light. I've seen someone installed dial in place of driver side 12V. I like that idea since I don't use it anyway. Is there a base plate to go there instead of rectangular from the kit?
Found this one but still would like to have the whole assembly seated tight.

It may have been me that you're thinking of, but I didn't use a third-party face place, so maybe not.Yesterday installed my V3 module and it took 2 hours including fishing the wire to third light.

I drilled into the lid. It was a real pain in the ass. The lid is made of multiple pieces and you have to be very careful / go very slow. I am very happy with the end results, though.

I've recessed the clear hex part into the switch since then so now it's even nicer looking:
