Help Needed! DJI S800 With Ardupilot Flight Controller

Hi everyone,

I am having some trouble setting up my DJI S800 with a Matek F405 HDTE flight controller

The DJI is a hexacopter with individual integrated ESC in the motors.
The input style for the Motors are 3 pin ‘servo style’ connectors.

Here is a picture

I’m assuming the input is + , - and Signal.
I was certain that the power can’t be going through these tiny connectors? There are much larger metal contacts on the legs that I am certain the power goes through.

Flight controller is the Matek F405 HDTE

My flight controller has 12 PWM outputs.
I just don’t understand how to connect the flight controller to the individual ESC.
