Dear [Ferrari Support Team], I hope this threadl finds you well. I am writing as a proud owner of a Ferrari 348 and I am in need of assistance regarding the wiring harness routing for the engine of my vehicle. In order to perform some maintenance work and ensure the optimal functioning of my Ferrari, I would like to request wiring harness routing diagram or photos for the engine. Having this information would immensely help me in understanding the correct positioning and connections of components within the engine bay. any diagrams or illustrations that would guide me through the correct routing of the wiring harness. Thank you very much for your attention to this matter. I look forward to your prompt response and any assistance you can provide. Best regards,
Never seen a harness routing diagram, but its pretty much under the intake on both sides then down the front of the engine. If you search for engine pictures and also for posts on engine out service you can see it. Pretty much put it back like it was when you took it off is how it works. Connectors are fairly unique so only fit inn one place/plug and line up rear to front with wire lengths. Good luck.
