Thanks! I did a lot of research trying to figure out the best way to mount and hide the wires. Since the power adapter included was not rated for in wall installation, I searched on Google for 2GIG GC3 installation manual. This will give you the basic panel guide for the non ADT version. That’s where I found on page 28 the maximum wire gauge and length for connecting straight to the panel. This helped me figure out what type of in-wall rated alarm wire would work. The adt smartthings panel has the barrel connector attached into the back, so after fishing the power wire in the wall I had to carefully remove the mounting plate and then back out the small screws to remove the barrel connector. I then inserted the positive and negative wires into their terminals (positive and negative are marked on the circuit board). I then used a replacement 2GIG power supply with positive and negative screw terminals on it that allowed me to attach the other end of my wire. The model for this item is 2gig AC1 (I bought mine on Amazon). Hopefully this is helpful.
