Electrolux 122/Water Pump relay box wiring

[clinning]

Hello. Will start off by first saying I have googled this prior to posting but I do not understand wiring diagrams that well. The problem I have is the white box behind driver seat the wires are not connected and was wondering if some one has a picture of which wire goes where. The fuses on top were wired just the spade connectors in side. Had a go and fridge was working but the switch did not make a difference and was constantly on and so drained my battery.

The van is a t25 Devon 1.9 DG and the fridge is the 12v / gas model.

Should I hear a click from relay when fridge switch is operated?

Thank you. Marc
