@JKirkChavez - thanks for the additional pictures, I think they gave me the clues to answer all of your questions.

  1. Cut the zip tie holding the cable going to the DB-15 plug in the bottom picture. Any wire in that cable can be removed from the setup. I think all the small silver color, stranded wires in the zone terminals will be these wires.

  2. There should be a white wire coming from the rain sensor. I think there is a wire nut where this wire is connected to another wire coming from the field wire. Put the the other wire into the Rachio C terminal (disconnect the wire nut and the white wire from the rain sensor).

  3. If you want to install the rain sensor here are the instructions:

TLDR: White and one Red to VAC -, the other Red to VAC +, Brown to S1 (and enable Sensor 1 to be a rain sensor in the Racho app).
