Moving from an old Rainbird ESP8 to my Rachio 12 Zone. I am going to wire my house power to the plug inside the Rachio waterproof housing and use the two-prong plug supplied with my Rachio 3 to plug into power. The old Rainbird has two wires from its transformer to the 12V+ and 12V- connections on…

@hdsteele - The voltage is probably 24 V AC, not 12 V. Correct, ignore the old Rainbird wires going from its transform to the terminals. On the Rachio unit the 24 VAC + and - are for sensors (e.g. wireless rain sensor) if needed.
