this is an interesting discussion, that made me rethink what i've done. here's my experience:
i recently (about 2 months ago) replaced some bulbs around my car with led bulbs, including the tail lights. i used these - http://cgi.ebay.com/ebaymotors/2-RE...goryZ33713QQihZ019QQitemZ8071214462QQtcZphoto
then, shortly thereafter, i did the fog light mod from the "how to" section. since then, my cruise control hasn't worked exactly as you would expect. worked fine, as long as the lights were off. but as asoon as i even turned on the running lights, the cruise control would kick off, the same as if you hit the cancel button. i was like - WTF! i was ready to call the dealer and schedule a diagnostic session, when i came across this thread.
so, today at lunch, i rip into my tail lights, and replace them with the original bulbs. and guess what? my cruise control now works as it is supposed to. no lights, works great. turn on the lights, still works!
after this little experiment, i'm convinced the cruise control is tied into the circuitry for the running lights / brake lights some how. whats puzzleing, is that i couldn't find anything in the wiring diagrams i have to suggest as much. must be some hocus-pocus in the cruise module box.
