How to connect speed controls to motors?

I've got a F450 ARF kit. The speed controllers have single letter labels on the connections to the motors. But the motor wires are not labeled. How do I connect them? Or does it not matter which wire goes where?
Thank you.

You have three phases on the speed controller and three on the motors. You can connect any of the three together. If you want the motor to spin in the other direction just switch two of the phases.
The speed controller themselves have to communicate with the FC ( flight control ) and here you have to watch out that you connect ( servo cable ) the speed control to the right port on the flight controller.
