FSA Energy Compact Bar - Internal Routing Q

Wondering if anyone has the FSA Energy Compact alloy bar, they’ve updated them to include some internal routing holes.
Wondering where the wires exit out of the bottom, if its from the stem or from the bar itself. Trying to mate this up either to an Easton Carbon stem or a Cannondale C3 alloy stem but can’t tell from the pic below exactly where the wiring exits and if i need a special stem to mate with the bar.
