    Need to wire a couple wired rain sensors to 2 Toro controllers with booster pumps. Just wire to the rain sensor ports, or does it need to be wired to the common off the pump start relay that goes to the booster pump?

    You didn't say which Toro controller. Maybe start by replacing them with good ones by Hunter or RB.

    Seriously - you should be able to wire direct to sensor ports.

    As always, TEST to make sure booster is also shut down by sensor.

    If wiring to ports to sensor ports doesn't work, attach one leg of sensor to commons from field including pump-start, and the other to common port on controller.
