Water Pump Relay

I am having a problem with my water pump switches. The red light that shows that the fresh water pump circuit is active comes on by itself from time to time. All pump indicator lights are on simultaneously as if someone has pressed the pump switch. I can push the switch and hold it for a few seconds and the light goes out. But usually comes on again very soon. I suspect a bad pump relay. Can anyone tell me where this relay is located on a Tiffen Allegro Bus 2005?

I think that relay is located in the wet bay behind the the plastic panel that the outside shower is mounted on. Steve

If you have the same light switches as our 2011 Bus I find we are always turning the water pump on by accident. I wrote Tiffin and suggested they either remove the water pump switch from the light switch panel or install a separate pump cutoff switch.

I would frequently see that the red water pump light was on in the service bay and we were connected to shore water with no need for the pump to be on.

I went to the outside service bay and cut one of the electrical wires leading to the water pump then installed a single throw (OFF /ON) switch in the circuit. Now regardless how many times I accidently turn the pump on by hitting the wrong switch on the light panel the pump won't come on unless I turn it on outside.
