No, open the system, check the switch in questions, get a soldering iron and desolderer to remove the switch, do it carefully, when you have the switch in your hand go to maplins or somewhere like it, find an exact replacement(wont be hard to do) and get someone confident with a soldering iron to solder it back in.

hi there
you will need to get a larger ground wire and it needs to be mounted to metal surface. this means you may have to scratch some paint in area where you will place the new ground wire (note do not add any other wires to this ground)
if that doesn't solve the problem than your settings may be to high on the amp but this sounds like a ground issue also make sure no fuses in amp are blown
hope this helps

If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following. I'll assume that you've checked the amplifier's on-board fuses.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.

Let me know if you have any other questions.

L LINE
E EARTH
N NEUTRAL

I'll assume the pump is 240 VAC. So be sure the pressure switch is properly rated. The termination labeled E should have a bond to metal frame. If true then;

L Black (Line 1)
N Red. (Line 2)
E Green (Equipment Ground Conductor)

Surround Sound Audio? Yes, you are missing the plugs. The small notch in the left of the socket (top in your image) allows the plugs to be inserted one way only. This preserve the polarity + / - to the speakers. Ask for them back, presumably, he took the speakers as well? or Google

Mostly a socket at the back of the amplifier section and AUX is now somewhat dated and LINE IN or LINE OUT is a more common legend these days.
There is likely a switch or button somewhere that controls it if you can find a socket, though it is worth mentioning if your hi-fi is not the separates it appears to be but a console, it is possible the manufacturer thought no AUX would be necessary.
