Esc with signal and telemetry cable. How to plug to pixhawk pins?

I ordered speedix gs30 32bit escs. Im planning to install it with my pixhawk. How ever it comes with telemetry and signal that im suppose to connect. Will it be fine just connecting one pin to the pixhawk signal pin? No pin will be connected to the + and - on the pixhawk 3 pin signal column.
Thanks everyone. This will be my first drone build.

Did you look at this?
