I followed some great instructions from this Scoobymods thread
The install took about 40 minutes, but a bit more time because there were some steps in the other writeup that were not covered well.
The airbag and the front cover of the wheel are one unit and do not detatch from each other. The two Torx-30 bolts on either side are indeed captured, but they're still tricky and try to keep you from getting the airbag on and off.
The electrical connector is a PITA...without using a screwdriver to pry them apart:

Removing the black connector at the bottom rear of the wheel housing is necessary. It just slips out laterally. Apparently JDM cars don't normally have cruise control, so the USDM connector has horn and cruise, not just one wire for the horn. Simple swap.
The horn ground and cruise stalk were easy to remove, using the same Torx-30 and a Phillips screwdriver:

The 17mm center mounting bolt was not as tight as I thought it would be. I did have to pull violently on the wheel to get it to come loose. I'm a strong guy, but I was really surprised. I took the ScoobyMods advice and didn't take the nut all the way off, which saved me from getting my teeth knocked out...
Install was pretty much the reverse of removal. Everything slotted in where it needed to be.
Don't be surprised if, like me, you get the steering wheel off by one or two teeth. I had to drive around a bit, adjust it, then drive around more to get it on perfectly centered.
Cruise works, horn works, car turns...success!
I like it. Looks better, grips better and the preforated leather will be nicer in the summer and during spirited driving when that extra level of grip is even more important.
