Apologies if covered before (I don't visit that often these days).
EVF. LEMO end. Unscrew the 4 bolts attaching it to EVF body. Lift and Rotate 90 degrees so that when the EVF cable is attached, the right angle points skyward (not towards the camera).
Thanks to Keslow Camera (Los Angeles) and Boa Simon for this (did this a looong time ago). So simple, I never thought to do it.
