radio wiring diagrams

[livo]

Hi, I have just bought a vivaro to make into a camper, and bought the satnav genuine stereo to replace the standard stereo I even got the satnav wiring loom as it just plugs in to the main loom behind the stereo and the connectors on the 2 stereos are different. Once replacing the loom to the satnav one, I can have the satnav working when plugging in the big and little connector fine, but the other long thin connector, when I connect this in it makes the dash turn on without the key plugged in, and the stereo just has a flickering back light on the screen and it does not work at all. Without this connector I don't get the microphone working all though I know which wires they are in the long thin connector but there are 6 other wires in that connector 2 yellow 2 that look light pink and 2 that look white or light beige, the stereo does not turn on or off with the ignition, and the screen does not dim when the lights are turned on, does anyone have access to the wiring diagrams for the sat nav and standard stereo they could help with so I can swap pins in the connectors or what ever is needed to get it working as it was intended. Thanks in advance if you are able to help.
