Wiring diagram - 365GT4 2+2 / 400i

I came across this link on Ferrarichat, thought it's a useful link to share

The wiring diagram is also present in the owner's manual. All of these are available in the download folder.


  1. Hello,
    I am currently restoring a 400i from 1980 but cant seem to get my hands on a wiring diagram of this car. I have the original book from 1983 but the fusbox is defintely different. Can you help obtaining the correct one? I have problems getting the light in the front to work properly especially the dipped beam>
    best regards

  2. Hello Jeroen, apologies for the late response, I only see your message now. You can find all relevant documentation and diagrams in the download folder. Let me know if I can be of any further help. Best regards, Erwin
