Using trap focus with AF lenses.

A friend wants to try trap focus with her DS. She only has AF Pentax lenses. Which contacts do you short out on the body/lens to do this? What do you use to short them out?

One reason is macros. You can move your camera in towards your subject until it is in focus and then the shutter fires. Another, birds could move into the focus range and trip the shutter.
