For signal wire, I am trying to wire up the Basic ESC to a pixhawk but unsure which wire (white or black) to use.

Normally the black and white go to the thruster commander

Any direction would be great in terms of wiring up to a pixhawk to the basic ESC

Hi @Blake101,

The black wire is the signal ground, and the white wire is the PWM signal line. Both plug into the Pixhawk servo rail, with the ground facing up towards the top labelled surface of the Pixhawk. The pin outs of the servo rail are also labeled on the side of the Pixhawk.
