Subscribing for interest as well.
FYI, on my 2002 USA CR-V, I put an RSX intermittent switch and it works flawlessly. It involved removing the old stalk, putting the new RSX stalk (plug and play), and then the additional step of wiring a single (or was it two?) wire from the stalk to one of the pins on the harness (somewhere farther below the steering wheel). It was a 20 min job , quite easy. It does everything you'd expect, including the typical 'single wipe' when you let go of the brakes at a full stop etc...
I want this on our 09 Fit!
EDIT: This PDF should be of great help in uncovering a mod for the Fit:
