Adria Compact Plus SP 2019 / Water pump set up

[Cliffyboy16]

can someone please post pics (or advise) of their 12v submersible reiche water pump connected to the whale In- line pressure switch WU7207 (b) and then to the 4 way connector plate to the EP-12-10 5A DC/DC connector box (this looks like it’s sealed so haven’t tried to disassemble it). So can see if I have connected it all correctly
never took pics before I dismantled opps

.
water pump was working fine on ehu until I moved pitches
i have bought new pump and new in-line switch ( broke connector) and its still not working properly.
Out of Interest i tried the old pump directly on 12v via cig lighter connection and works

Can anyone help out here?

I don't understand why the voltage to the pump is being reduced, that's what the silver box thing is doing, but then I don't have any Adria specific experience.
If, as you say the pump works fine on a direct 12v connection, I'd remove it from the circuit.
Where does the other end of the blue wire go? My assumption is that both it and the brown wire go to the pump, that being the case, it will need to connect to the negative line, so it should be connected to that exposed terminal on the block of 4 spades, a new connector is required for the end of the blue cable.

Given that the pump is of German origin, and normally in German wiring brown is usually negative, I'd think about switching the blue and brown leads over, might make a difference

Others may be along with more product knowledge.

Edited to add...
There needs to be some insulation over that exposed yellow wire terminal.

Thanks, yes I don’t why the voltage to the pump is being reduced either - hoping someone would know. I have never had a water pump problem in any of my previous motor homes hence unsure what to do. Only this one and I did point it out to the dealer when I bought it as the water doesn’t go fully around the loo which it did in my old Adria Twin van - they fobbed my off but at least I can get a decent shower in this one. I am so use to using a plastic water bottle with solution in to flush the loo.

Yes the blue cable goes into the connector box with the circle no 1. I have bought a new connector box but wanted to get the cables correct before moving over. Yes both cables where exposed originally on the pressure switch as I broke the connection whilst trying to undo hence new pressure switch and forgot to take pics of it as I wasn’t expecting to disconnect it.

I will try and see what happens when I swap the blue & brown over
