the last and longest section of the plug is the common.
connect the metering and focus part to the common, and plug this into the camera. it will remain "active" 100% of the time, just like holding your finger on the shutter release part way down
Very interesting info. When I first got my K10D about 14 months ago, I tried wiring up my own cable release, using telephone wire (3 conductor). I was not aware of the multi-function (metering, focus and shutter release) that you describe, so I used a mono (not stereo) plug which I happened to have. And it has worked well for me for over a year now, but only to trip the shutter. And yes most of the time I am in Manual or Av for the exposure. But I am in AFS or AFC for focusing. That's the bad part, for me. I've wished all this time that I could utilize the AFC with this cable remote. Maybe, now that I know this trick, I can figure out a way - after locating a stereo plug, of course.
Incidentally, I have two sections of cable I can connect in series, and can sit back either 15 feet or over 30 feet, and it works fine. I rigged the pushbutton into a small pill bottle so it would be more comfortable to hold and press the button as quickly as the subject appeared.
Thanks,
