So you’re keeping it as is ?

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?
