I have a 2016 sterling elite & need to know where the wiring plug is that goes to the back of the water inlet is as the housing has been changed to a shower one & I need to change it so I can pump water from barrel into caravan but I can't find a plug or any loose wires under seating that would go to housing to provide power to the outside barrel pump.

The picture is what I need to fit but need electrics for it.
