Maxbotix EZ4 (Analog) + Pixhawk 2.1

As all of you know, the plugs on 2.1 are totally new. The set that comes with PH2.1 does not include an ADC port cable plug. I have 2 questions:

  1. I assume I plug an analog sonar (Maxbotix EZ4) into the ADC. This is correct, right?
  2. Where do I get an ADC cable head for the new plugs?! (3-pin)
