Thanks for this image example, @TStarr2! That Pro Power Kit certainly looks to be properly installed. Indeed I can also see something that stands out with the wiring. The color of this wiring is usually an indication of spliced thinner gauge wire or cat5 being used. Of course, that is just my observation, and it could be normal wire.
Just to be sure of the wiring, check out our Hardwiring Checklist for the Doorbell Pro, including tips on wire gauge, chime compatibility, and more! Feel free to let us know how this goes.
