Thanks for the link to the thread. Unfortunately the links in that thread don't work anymore, but it lists the pins and their corresponding functions.
I took a small piece of tape and covered pin 10 (Green Button). I put the grip on the camera, turned it on and the green button was disabled!
Everything else seemed to work properly.
I'm thinking of using a really thin plastic tube with the end melted shut to place over the pin as a more"
permanent" solution. This way it's still completely reversible.
Thanks again for your help!
