Wiring multi engine edf
 
I have the Airbus A380 edf. I bought new escs for it. Can I use Y-harnesses to connect all the power wires and all the servo wires so they run from one battery and one receiver?

Yes that works. You can think about using only one bec wire and pull the red line of the other escs out.

Too long battery wires can kill ESC: precautions, solutions & workarounds - RCG
Keep controller(s) close to battery, if possible, and extend motor wires instead.
Keep the battery wires short, or else install extra capacitors, all on/near ESC.

But not when they are optocoupler ESCs, otherwise the optocoupler LED does not get power. No pulse/information from receiver to controller.
I'm not referring to the HobbyKrap opto nonsense/lies, where opto means no-BEC. (I call a car without a steering wheel diesel. Very obvious, right?).

Do not cut the red wire, you may need it again in another plane.
