TBS Crossfire Mavlink and CubePilot

Hello all,

Trying to configure my TX16s and TBS Crossfire Micro V2 to work with the cubepilot via mavlink on the telem 1 port. Can anyone please give me a pinout? I have power and ground working (believe to be first (red) wire and last black), but cannot seem to get RC to appear connected in mission planner despite trying various TX/RX pairs.
