I am not familiar with that ESC, but some rules are universal.
All ESCs have a "front end" that does the control, which needs a regulated 5 volts ot work.
They also have an output stage that runs on the main battery voltage.
Some have a BEC the convert main battery voltage to 5 volts, supplying the front end circuit and, through the red wire in the servo lead, everything else.  With more than one ESC having BEC, it is good practice to isolate all but one of the ESC front ends by disconnecting the thin red wire on the input cable (Do not cut - ease the red pin out of the holder and tape back)
ESCs that do not have a BEC need to keep all their wires.
It is a good idea to draw out what is wanted and compare it with what is there.  When looking at a problem like that, I find that it helps to have somebody else check - I find it very easy to overlook my own mistakes.

it works everything as it should be .. and the motors also turn opposite ..

I reconnected the + cable and connected the two regulators with the Y-cable..
