There is no relay for this. The black box just has a few resistors in it
AFAIK.

The way I have bypassed the empty tank pump shutoff feature is at the
LED panel. Remove the kitchen drawer to get to the connector and then
remove the led panel.

There are 5 wires to the panel.
+12 volts  comes in on the Orange wire
+12 goes back out to the Pump on the Yellow wire.

Disconnect the Yellow wire from the LED panel and connect it to the
Orange wire. Then the pump will have 12 volts available whenever the
panel does.

I just unsoldered the Yellow wire from the panel and resoldered it to
the same place as the Orange one.

With the newer panels the factory does it at the connector and connects
a shortened yellow wire to the orange wire right there. In either case
be sure that no exposed bare wire can short to any metal parts.
