Pixhawk 6C connection with ESCs X650 Holybro frame

Hardware Multirotors

I just got my X65O drone frame with Pixhawk 6C and Tmotor MN4014 KV330 Motor with Tekko32 F4 45A ESC. So, when I was connecting the ESCs to Pixhawk main pins I noticed that the ESCs have 5 wires instead of 3. Two of them are white and black, the other three are yellow, red, and black. My question is which wires should I use since I was working before on F450 frame where the ESCs had just 3 wired red black and yellow which are Vcc, GND, and Signal respectively, however for this one I have 2 signal wires 1 VCC and 2 GND.

Anyone can explain why?

So, should I connect all the 5 wires to the Main and AUX pins of the Pixhawk so that the motors work? And If I connected just yellow, red, and black is this okay?

Can you post a picture of the ESC and its wires? All the Tekko32 ESCs I see online don’t come with wires at all.

I suspect the extra yellow wire is for telemetry or TX, but a photo will help a lot.

I figured out that the yellow, red, and black wires are for LED NEO Pixel.
