I bought a 12 zone kit. Can I use the Aux+/- on the extra second kit, the one with only two black connectors on the left, as output? If so, what's the output voltage and amperage? I'm not sure if I'm misunderstanding electronics, but I'd want to use the wired alarm panel cable to power a touchscreen display. I'd imagine I can just connect the plus/minus from the old system to Aux +/-, then connect +/- to a solderable USB female header for power right? This is easier for me than wiring an actual outlet there. Thanks in advance.
