Sorry for your loss....
Like Sandor says. You have a LOT of equipment connecting on the Cortex/REX7. Without the power lead you will blow up the RX1 and RX2 of the CB. Why didn’t you use the E ports of the CB to connect all your equipment? (CRU, GPS, expander, Fadec)
Even with the Cortex only it is mandatory to connect the power lead.
