ESC powering Pixhawk?

My project uses a trolling motor with a 30amp ESC. Prior to using the Pixhawk, my ESC would power the RC receiver. Now when connecting the ESC to one of the Pixhawk main output signal pins, it powers up the Pixhawk.

I'm concerned as this bypasses/negates the power module and I don't know if the power from the ESC is regulated.

The wire running from the ESC is the standard pos/neg/signal (yellow/red/brown). Should I just blank out the positive and negative coming from the ESC to prevent it from powering up the Pixhawk?

Also, can I use the ADC 6.6v from the Pixhawk to power my RC receiver? Has this been done?
