    There are dozens of small wiring diagrams in the OEM manual. What is broken?

    Are you looking for the complete cables or trying to find faults- there are a lot of different diagrams

    So you want to know everything that goes through the two 40 pin plugs just in front of the firewall. aka. XL41 and XR41... or you want to know everything which goes through the firewall?

    It would take weeks for Mike to find all the diagrams for those. I tried to create a pinout for one of those and gave up. There were just too many mistakes in the original Ferrari diagrams.

    I found that one alongside many others.
    I still have not got my window switches sorted out, still on all the time. You have a more up to date solution

    Not really. The diagrams don't match the car. The diagrams show the lights powered by the Window Control Unit, but aren't the switches illuminated by the 2 pin plug on the HVAC panel?

    What happens when you turn off the radio?

    The HVAC panel gets two sources of power. Light power from fuse AF5 /relay AR11 in the frunk and key power from fuse PSF13. Neither of those should be providing power with the key off.

    It doesn't look like the HVAC ECU provides any 12v power to the control panel. But since some of the knobs on the panel are just resistive circuits, the HVAC ECU has to send current through those.

    Sorry, senior moment... I got my Radio Panel and HVAC panel mixed up. I don't think hitting the HVAC STOP button will turn off the lights, but give it a try anyway. Also try your Recirc Switch.

    Is your HVAC system working normally? Also, are the panel background lights working?

    Sorry for the thread hijack.
