I looked back at the previous thread, and it's pin 7 on the face of the camera's lens mount--counting from the bottom.
If the lens doesn't cover or contact the pins on the lens mount, either turn off the Tv Shift function or don't push the green button. Use the exposure scale at the bottom of the view screen to set your exposure. If the lens is large enough to cover the contact pins and is conductive, you won't see the exposure scale, but you will be able to use Tv Shift with the green button.
I've found that using the exposure scale isn't as convenient as the green button, but it does give you more manual control.
