Why does base HVAC have more connectors than digital climate control?

Tested on the two matching connectors, third connector left dangling unplugged, stock manual blower resistor

Lights up and sorta-works plug and play, as expected no front blower control (screen settings "change" as desired, but no physical reaction to em) without further hotwiring

So you’re keeping it as is ?

Idk

I ended up sorta-exchanging the Android Atoto 7" for a new 10.1" model (all the soldered connectors and 3M taped down outboard antennas are identical and interchangeable, making the switch pretty plug and play return-as-unused a bunch simpler -- just transfer all the sealed baggies of stuff from the 10.1 box to the 7.0" box, reset and repack the small head)

And that swap DOES make gloss black the dominant color on the dash anyway.... so I'll consider it probably

Or maybe track down one of the hella-faux Eddie "wood trim" panels

All in one (Simplified)

C2357C stays unplugged (new panel doesn't have a slot for it)

And the rest below is self-explanatory

C297 or C2185 (same connector, different designation) is never touched

Which trim with upgraded hvac used a black piece? Top is Limited, bottom is Eddie Bauer. Both use a simulated wood panel:

Couple question:
1) So you swapped the resistor for the heatsink-looking thing and spliced the wires coming out of it as @TXFRDOwner and I were theorizing to get blower control? Right? Any surprises there?

2) What's this plenum thing, though, why do you cut it, and what relay were you fitting in there?
Is this one of the attempts to get maximum functionality, or would there be no basic functions without that?


Here is an image with the resistor removed:

No surprises, but it is a little tight to work in there. On the first go round, I wired everything like the schematics, utilizing any wires already routed. Eventually, after revisiting and rechecking the wiring, I found the harness that connects the blower motor, relay, and other connector(s). It cleaned it up the wiring a little, but it was more for me to confirm wiring.

It's probably best to mount it here, as that is where it is supposed to go. I believe the guy on the F150 forum temporarily left his hanging outside, but it gets really hot. I referred to the new part as a relay, but it is the blower motor speed control (mine took a Motorcraft YH-1829), you need need it for the blower to work unless you hack it someway. Given that this part gets really hot and often burns the wiring and connector, I would wire it properly paying attention to wire size:

Damn

Hadn't realized cutting was involved

How'd you get in there to dremel that? Flex attachment and cutting wheel?

Or the grinding bits?

Start with a hot knife or a cheap soldering iron, ... then finish up with a utility knife
