    Relays on a 348 are old so I replaced the relays for good measure, and it takes some cross reference so I thought I would put it all in one place with the new part numbers and board position. There is 5 different relays. 1 is still available with the Bosch part number "the one with the blue K on it", the rest have been superseded, 2 of them are easy to xref, the other 2 take some work. So all in one place now.
    • First is a picture of the fuse panel behind the passenger foot pad. It has the relays marked using Ferrari part numbers as well as position A-R as well as the new part number.
    • Second picture is the same with the new relays in position also marked by position. If you mark the fuses on the board A-R as well before pulling you should be able to pull and replace easily as well as put the old ones back if you need to.
    • Third and forth pictures are of the 4 new relay part numbers. You can zoom in and see the part numbers circled in red.

    5 relay part numbers....
    • All the brown ones are the same, get that part number in red and you have all the brown ones, there is 9.
    • C,D,L,N are the same, get that part number in red and you have those 4.
    • B,F,H are unique and occur 1 time each on the board you can see the part numbers in red.

    I can't read the "H" short black type numbers. Is it Italamec 02301? or 02391? Or?
    Is there a good source to purchase/obtain these?

    According to the manual, relay H is Italamec 0239100 (time delay for switching off steering wheel locking lighting)

    Not cheap... a special item

    If you don't want to spend the kind of money a new one costs, and if the problem you are having is that the roof light will only come on with the passenger door open, you can fix your Italamec for $0.50. The Italamec can be opened and, to solve the mentioned problem, just replace the large diode inside. Any standard 5 Amp diode will do.

    For the original 4140 relays in position C,D,L,N you can alternately use GM part number 90491314 courtesy of Miro -> https://www.ferrarichat.com/forum/posts/145512052/

    I actually bought 4 of them from http://www.hamofaengine.com/default.htm for $15.24 USD.
    Here is what arrived but in the end I used the ones in the picture above I also got so these sit on the bench.

    btw you can find most of these on ebay from Latvia or what not at resasnable rates. I actually got new bosch a/c relay from ferrparts fro the front fuse panel for example. Actually I think I got most of them from ferrparts I forget.

    There are other cross reference numbers available to btw. You can also use Bosh site to cross reference to other bosch where applicable (not always applicable many you have to use tyco or others) https://secure.bosch-classic.com/en/produktsuche

    In any event the ones I show are just come possibilities, but I be believe it represents the highest quality not the cheapest however. There are cheaper options too, like the ones I got from Hamofa and there is a real possibility the cheaper options word every bit as well maybe better who knows.

    But what I show above is what I did and I am comfortable with it.

    Doh- I highlighted the wrong part number on the brown ones, four of the are also in the boot relay board as well. 75% of the relays in the car are these. - BOSCH 0 332 019 151

    It is interesting that Bosch is now, in addition to their standard numbers, also placing numbers starting with "V" which are, as far as I know, relay number types (codes) used Siemens and Tyco (perhaps they all bought each other).

    I noticed that when cross referencing because sometimes they xref to each others like search for Bosch take you to Tyco etc depending how or what you search. Made it confusing at times.

    Those four 4140 relays used for fuel pumps etc that say TE are not even Bosch as far as I can tell.

    "TE" means Tyco. Bosch had a couple of equivalents to their old 0 332 014 140: 0 332 019 140 and 0 332 209 168 but these are also hard to find. These relays a re a bit special as they are "low pull-in voltage" type, i.e. they have stronger solenoid coils and can engage at as low as 7 volt. I found out that one, possibly fairly new, Bosch equivalent is 0 332 209 136 which is GM p/n 90491314. This GM p/n is also manufactured by other relay manufacturers like: Hella 4RD 007 794-05, Siemens V23134-A52-X237 ant Tyco (TE) V23234-A0002-X031 (or X032) which has even lower (better) pull-in voltage of 6.5 volt . I do not have the specs for the Tyco relays (4) you got for the fuel pumps and injectors but I presume they are similar to the Tyco number I mentioned.

    You can get the GM part number 90491314 from here, They were really inexpensive. Paste the part number in the search bar and they come right up. https://parts.hamofa.com/?ls=en

    I ordered 4 actually after seeing your other post about them, and below is what showed up
    Do those seem correct, not sure what showed up was right so they are sitting on my bench.

    The correct relays to use for the fuel pumps and injection should, in addition to the manufacturer's number, also have "GM 90491314" stamped on them. These relays are well known as the "brown relay". I happen to have these by Bosch, Hella and Tyco (numbers as I mentioned above) and they are all brown and have "GM 90491314" embossed on them. Anyhow, you can check the resistance between pins 85 & 86 of your shown cheap relay and, if it is around 90 Ohm, it is an ordinary relay. The genuine GM brown relays have the said resistance of about 65-70 Ohm, same as what the 348's original relays "140" for the pumps and injection have. You can do the same resistance check on the black TE "X064" relays you got to verify their suitability for the pumps and injectors.

    Otherwise, I think I found out why the Bosch "151" relays also have the "V" (Tyco) numbers on them - Tyco bought-over the Bosch's relay division some time in 2006 and the Bosch relays are now also called "Tyco/Bosch".

    The Hamofa site says "GM 90491314" but I got those pieces of crap. Theye may be equivalent but they are not going in my car. The actual GM ones are harder to find than the Bosch ones I can only find the GM ones used. Same for the other cross refs to 90491314 like V23234-A0002-X031. Onlt find used one..

    This may be helpful for someone also https://www.lh.pe/file/v2323.pdf

    v23234-c0003-x064 I am using, hope they are the right ones there for those 4.

    I bought new genuine GM 90491314 relays (Saab) at: https://www.rendcarparts.com/en/search/search (key in the GM number in the search box); now only 2 in stock
    Otherwise, based on the document you provided, the Tyco relays V23234-C0003-X064 you got are equivalent to Bosch 0 332 019 140 (black plastic) which was used on later 348s (I have 4 of these from a 348 relay panel I bought) in replacement of the older (first) Bosch 0 332 014 140 in metal housing. So, the Tyco relays V23234-C0003-X064 should be fine.

    For those interested, Tyco is now TE, the replacement relay they claim is 1432790-1, they unfortunately measure 90 ohms. My search for the correct relays for fuelpump and fuel injection relays continues.......

    The correct relay for fuel pumps and injection, GM p/n 90491314, has been superseded by GM p/n 90543014 which comes either as Bosch 0 332 209 136 or Hella 4RD 007 794-05 or Siemens V23134-A52-X237 or Tyco (TE) V23234-A0002-X031.

    Thanks, followed your previous advice, the difficult relay is the fuel pump relay, (60 ohm), the fuel injection relay is fine with the TE part. Ill look at these places, however in addition to looking for the right part, Im also looking to pay the right price.......

    The Injection and the Fuel Pump relays are identical, both are required to be ~ 65 Ohm.

    SaabUSAparts.com says they don't carry the 90543014 relays anymore--just tried to order 4 today. ChevroletPartsDirect.com has them, but they're US$53 each....

    Thanks for the all the research, guys!
