Emax MT2216 and Emax 4in1 wiring

Hi All
Maybe it’s trivial question but I want to be sure
I get four emax mortors (MT 2216) and emax 4in1 ecs. ( 25Ax4 upgraded from simonk)
Each motor has three wires but each of them has the same color ( all are black)
In emax ecs i get A B and C connectors for three wires from motor.
How it should be connected ?

There is no wrong connection for the motor wires.(Except for connecting the motor wires directly to a battery).
Just connect all three and observe the direction the motor runs. If you need to reverse direction, just change two of the three connections.
