So you'd have to solder to those pins, they are there in my grip making contact.
Hmm. Moreover this RX-TX signals go to the battery slot from main board, so may be soldering to the mainboard (e.g. near the appropriate connector) would be easier. But I don't want to solder to the cameras pcb.
Please correct me if I'm wrong, you write that you have the grip that has the middle contacts missed in the original Canon grip?
