At this point, I would grab a multimeter to confirm the pump output is in fact switching. You can do this by setting it to VAC and seeing if you get an AC voltage. If you have access to an oscilloscope, that would be even better. You could see the wave form then. Then after confirming that, I'd probe around until I found 12Vdc and see if that is switched by the Omron relay on the top. Then try to solder some wires to that connection. Can probably just choose whatever is an available ground that is easy to solder to and whatever gives you 12Vdc that is switched by the Omron relay.

I checked the output and get 0.7VAC.
Not sure if I want to start soldering in jumpers. Would have to make sure the timer doesn't get bypassed.
I guess this would also explain why the other pump I picked up will not run when connected to the controller.

My ATO system is my own design. I have two float switches that connect to my RPi and that triggers a relay. I use a Sicce 1.0 and push the water thru a mister head. Doesn't mist too well. Plan was to use the mister to rinse the salt off the mangrove growing in the sump.

It’s probably a tangent but I take a different approach. I use my stock RSR gravity fed ATO and keep that full from a remote RODI reservoir via a PMUP programmed to run once daily. As the pump is remote I don’t care if it makes a little noise. And of course the gravity fed ATO is completely silent.
My only addition is a low sump level optical sensor in case the gravity fed float valve gums up. If I had the room I could run two float valves for redundancy.
