Hello everyone, I have an electric issue with my 2011 G37. The problem is that my screen and A/C don’t work. When ignition is on there’s a little backlight/illumination at screen but it doesn’t work as it should be and A/C is still dead, only clock and lighting is working. The thing I see it may be some sort of short circuit in radio unit. My issue may come from cables, because when I stick yellow plug into yellow place, there’s a short circuit (I can’t turn off the car when running and generally ignition button doesn’t work, gauge light turn down and blower turns on high). Someone told me that the red place is responsible for screen but none of my plugs match the red place. Can someone tell me is there any bypass (or things similar to this) for that plug? Or I plugging it wrong? All parts have fitting numbers, fuses are good, and wiring is okay too. I would be thankful for your help
I can't quite find the right book to check this but ... are there more than one 24-pin plugs on that harness? Is the black receptacle below the red circled one also 24-pins? And if so, are you sure you have the right plug in the correct socket? Maybe ILM can confirm that for you. Also is your 2011 a sedan or coupe? Bose? With NAV or without?
I stand corrected. As your location indicates Poland I just assumed your car was EUC. Either way... I found this, perhaps you can trace these connectors and the wire colors and match them to yours.

Between the AV headunit, the UMAC amplifier, and the preset switch panel there are a number of 24-pin connectors... which is why it is SO easy to mix them up.
I posted a pic from eBay that, hopefully, OP can match his harness with those connectors and get it sorted. It would be virtually impossible for us here to sort out each circuit and being his is non-NAV that makes it even more trying.
