Once you get that harness hacked together, take some really good notes... Someday, if you keep the car for any length of time, and I get some time away from all the drama in my life, I'll see about building you a single harness for the whole she-bang.

Of course, I'll need a core harness (has to be from an HF) and one from an XFi or equivalent (the HF's harness is specific to that car).

This isn't a guarantee, though... just a suggestion that someday, I might be able to work on it.

If you want to choose your vents, you swap in the heater core boxes/vent boxes from a hatchback. They should be a direct bolt-in, IIRC. Something will probably not quite line up, though. That will give you cable-based access to the air-deflector flap (valve thingy). You might even be able to just get away with removing the electric motor that's on the box now (pull the dash, it's easier. You can leave the center console mostly installed, so you won't have to pull the climate control again), and replace it and it's lever with the cable and lever from a "normal" model.

ALL CRX's have push-button location adjustment, even the 1st gen ones. (Everyone I've seen that I can recall, anyway. Of course, there could be some that didn't, that I've just never seen.)

Later, if you want to tidy up the project more, companies like Lokar make custom cables that can work for swaps and such. No idea what it would cost to make a cable, but then again, I'm sure we could grab another CRX cable and another TBI Metro cable, and splice them reliably... I did used to make cables in one of the factories I worked for... These are all things that I can work on here at my house, and pick up/deliver them as we meet up in places, such as one of the local parts yards, so they don't require me to spend a day hours away from my family, or take time off from making money to support us, etc.

Anyway, those are some ideas for you to consider.

The climate control swap I can guarantee will work in some form, because my Civic Sedan had CRX climate control installed (by me) in it. I also had a CRX complete dash, and CRX Si seats. (Almost had the back seat, too... never could find it for less than $300, though. Instead, I installed all the cargo areas in the rear seat area. I even started on the interior plastics, modifying them to fit cleanly in the sedan's chassis.)
