1. The suspect uses a connector and wires to tap directly into the control board on the pump.

2. This 110v power then runs to an RF AC power switch (Figure A). https://a.co/d/eJBjR9L

3. From the AC switch the power runs around and to the door of the dispenser it is routed through the pump handle switch, which runs on 110 but has a built in DC converter.

4. From the pump handle switch DC power then runs into an RF remote DC switch (Figure B). https://a.co/d/iCETKux

5. From the DC adapter the power then runs through an Arduino board capable of setting the power to 24V and 5A that then taps into the positive and neutral lines for the control valve (Figure C). https://a.co/d/9hd7VKc
