The Leica Diagram indicates: Shorting pins 1+8 wakes up the camera (also turns on DMR) Shorting pins 1+2 firescamera. The official Leica cord is a dual action switch. By pressing it lightly, you short pins 1+8. Full depress shorts 1+2 to fire the shutter. So... I inserted the plug into my DMR release socket and tried shorting the pins with the tip of a small screwdriver (Damn - that sounds scary..) If you short pins 2+8 , adding pin 1 to the combo can fire the camera - or if the camera is asleep, it will turn it on. Basicaly reduces a dual action switch to a single action. This is my goal as I want to attach it to a pocket wizard receiver. Even more interesting - shorting pins 2 and 3 does the exact same thing. You don't need pins 8 or 1. This may just be a DMR thing. Not sure about the motor winder/drive. Eric PS - Yes, I am taking a few risks here. Reader beware. Tinkering with a DMR can end in tears, screaming or, likely, both.
