You have four servos in the wing.
Two of those goes to the ailerons
Two goes to flaps.
The two aileron servos are both connected together with a Y-harnes
The two flap servos are both connected together with a Y-harnes

These two harnes contacts are then put into the receiver on the aileron resp flaps position.
But...For a newbee flaps are not needed or desirable to use/have.
And most important! Join a club!!!!! There you can get help learning to fly!
