Excuse the question, which may be trivial, but it is taking up a lot of my time.
This vehicle has problems with the rear lights, in particular position and stop lights.
Sometimes a fuse in the front fuse box blows (fun to find), sometimes they just don't work.
In my opinion the junction (O4 from Marelli diagrams?) leading to the rear lights is damaged. I don't see it in the usual places like the heel bars and rear bulkheads. Can anyone tell me the correct position?
Thanks in advance.
