Water pump relay location for a 1993 U280

Subject says it all. Water pump is inoperative, circuit breakers OK. Anyone know where the relay in a 1993 U280 is located? No panic for now as I hooked up to park water while looking for the problem, but I hate hooking up to park water..... a flood waiting to happen as water is my nemesis.

Roland. How you doin? Is there 12V steady at the pressure switch? I would suspect the pressure switch first.

Roland - My wiring diagram shows the water pump relay is on the 12 volt panel in the middle storage bay.  The one behind the white fiberglass cover, where you also find the 3 big round 90 amp circuit breakers.  There are also two vertical rows of circuit breakers.  One row has 3, the other row has 4.  In the row of 4, the bottom one is power for the water pump.  Hopefully yours is the same...

In the photo, the panel is on the wall just to the right of the battery charger/converter:
