'03 Holding tank sensors

[bsinmich]

On this trip my holding tanks sensors always read empty. I also have a short orange wire with a female stake connector hanging down in my compartment below the panel where the water hose hooks up. I have used a mirror and can not find any open spots the connector might have come from. There are 2 other orange wires onthe backof the panel at the switch for the blower and also for the water pump. Any ideas if these 2 things are connected? Thanks.

I will check my location this AM, hold on.
The only wires behind the water panel are the two orange ones to blower motor and two yellow to the water pump.
The wires go up to above the blak holding tank with many more wire connected to other destinations.
Did not see any extra orange wires behind the panel.
Your holding tanks have with wires to sensors on tank surface connected into some type of block going into wire harness.
If both orange wires are connected to blower switch do not know were your extra one comes from.
As to your tank indicator reading empty you may have a loose ground lead behind panel over your door, they are all spade clip connectors.
