355 Wiring diagram

Do a specific search for wiring diagrams posted by Qavion.

 

Which version of the car do you have, Leo? 2.7? 5.2? Year? Teves or Bosch ABS? Spider? Country?

 

I'm not sure how you'd check without pulling your car to pieces. There are variations in relay numbers and fuses, but you'd need to remove the front luggage compartment liners to find them. Anyway, I've provided a link below to my standard 5.2 zip package with both Bosch and Teves (and USA and Euro-based lighting diagrams).

I've been developing and improving them over the last 5 or 6 years and upload my latest versions on a regular basis, so if you bookmark this forum post, come back to it for the latest version.

F355 5.2 Wiring Diagram Package

There are a great number of variations from car to car and I haven't been able to provide diagrams for all. I've tried to add notes to the diagrams to highlight a few of the variations, but there will always be something I've missed. I have set of (non-F1) Ferrari F355 paper manuals for the USA, so if you have a specific wiring fault, we could go more deeply into specifics, but I'm not entirely sure Ferrari have covered all the variations.

Hope this helps
Cheers
Ian.

P.S. If you can upload the diagrams to an iPad or similar device, you can zoom and pan the diagrams to help with wire tracing. For editing, I open up the diagrams in Windows Paint.
P.P.S. If you could update your profile to show your specific car type, it will help us to diagnose any problems which arise.

 

Open the engine hood, within 5 seconds you can tell if you have Teves or Bosch.

 

How, Mitch? There are early 5.2 cars with Teves. Most of the components are hidden in the front luggage compartment.

 

The Teves system generates its own high pressure and does not require vacuum assist.

The Bosch brake system has a traditional master cylinder, vacuum power assist and needs a vacuum hose attached to it. There is not enough vacuum generated by the running engine so Ferrari has to use a vacuum pump driven off the rear of the camshaft on the left bank. It is a device about as big as your fist.

If there is a vacuum pump attached to the rear of the left bank head with a metal hose running toward the front of the engine, then you have a Bosch brake system. You flipping lucky bastard.

 

Seems I am a lucky bastard...
