    Hi, I have just had a new F1 pump fitted to my 355 and wish to protect my considerable
    investment in this by ensuring the relay does not fail closed and burnout my new pump.
    I have heard that there is a relay that fails open and therefore protects the pump can anybody tell me where this can be purchased, or is there an uprated one that will replace
    the standard relay.
    I realise that changing the relay regularly can help but this is not guaranteed as a component can fail anytime.

    Any help appreciated Cheers Rod.

    Rod- My 04 575M originally came with Ferrari part number 155437, Tyco V23134-B57-X203, I believe the same relay now recommended for your F355. I upgraded this to a Tyco V23134-B57-X266 with harder contacts that resist melting. There is now a further upgraded version, available from Juri in Texas for $56, that is a Tyco V23134-B57-X152, also with hardened contacts that definitely should not melt and fuse.

    In November 2003, Ferrari upgraded the relays on the 575M, 360, and CS, from 30 amps to 50 amps, with a relay already in service for other components in some Ferraris. Unfortunately, this required a new wiring harness with a different connector for the F1 pump relay and that relay will not fit the old connector.

    The upgraded 30 amp relays work fine and I have heard of no cases of either X266 or X152 failing. As you know, simple unplug and plug to change the relay. Very cheap insurance.

    Edit- Great find on the BMW relay, which is X152 from photos online, and is available online from BMW parts suppliers for $15-25. Will have to pick up one of those myself.

    Hi Just checked relay on ebay and the Tyco has five pins mine is a Euro spec car and our relay has only 4 pins.

    Rod- The Euro cars have a four pin connector? Sure you have the correct relay? That does not show anywhere in the parts catalogs. Those show they all use five pin connectors, US and Euro, and the same 30 amp replacement relay until November 2003 (with a little extra detective work). X152 is a 5 pin relay.

    If you have a 4 pin connector, very simple, use part number 233100, the 50 amp relay introduced in Nov 03.

    Daniel- Looks like 233100 might fit that connector. Can you confirm?

    John- Do not know. If we could read what was on the front of 233100, it might help.

    Contact Juri on this site Via PM.

    He has the proper F1 relay that fails open instead of closed and at a great Fchat price ;)

    I have two...one in the car and one on the shelf.

    According to Juri it's the other way around, X266 an upgrade over X152 (switches on/off faster and lasts almost twice the cycles). He advised me to request the orange relay (X266) when buying the gray one (X152) on eBay since he only lists the one that people know about. Same price.

    157991 is the same as Bosch 0332019103 four small prongs as fitted to Eurospec 355 F1 cars. I did not know they were 50 amp.

    Anybody know if the relay on the Challenge Stradale is un updated part from the factory or should I be shopping for the one you guys have mentioned here?

    Carm- Early Challenge Stradales had the old 30 amp relay. The new 50 amp relays and wiring connector updates were introduced around November 2003 on the CS, 360, and 575M. Exactly Nov 03 for the 575M (Assembly Number 52556) and I assume a similar timeframe for the CS and 360.

    If you have the old one, X266 would be a good investment.

    Hi Terry, thanks for that info. I went and peaked at the plate in the car and its stamped April 2004 so I may be in the clear. I will look at the relay itself next time I take the car out to be sure.
