    My latest project is to go through all the relays and ground connections in my 88.5. In fact if anyone can tell me where the ground connections are under the dash I’d greatly appreciate it. The good news is that everything checks out and is working property (including all 4 fans, more on that later). The rear relay box has one connector that was open. It’s a blue/red wire (marked with blue tape in the picture). I have the large (6’x2.5’) 5000S schematic and from what I can tell this wire connects to the fan cutoff relay (exciter). Am I on the right track? I wasn’t able to ohm it out last night since it was after midnight and my kids rooms are above the garage.

    I’ll also be replacing all of the relays. I have all the BOSCH part numbers, and cross referenced all of them and their pin outs with the schematics, except for the Fuel Pump / Ignition relay (the one with the fuse on the top). Any ideas on this part number? I saw one post from Jalpa_Mike (thanks for all your great info by the way, and Peter, Albert, Ken, Emilio, Raymond, Tim, Bob, Vic, Joe, Chad, countachqv, and everyone else – I know I left someone out) calling out a KAE 3.304.100 however I’m not sure it applies to an 88.5 and I cannot find a pin out schematic for it.

    Thanks, Larry

    Larry,

    Wish I could help you out more, but my 1986 has the older style electric boxes and thus use the standard BOSCH relay for the fuel pumps. This is what the box looks like on a 1986 5000QV (this is the unit mounted on the passenger side of the car, right behind the airbox (note how the heat also warps this box too!).

    My car also uses the K.A.E. relay (3.304.100) and from my service documents, it talks about placing a jumper wire between a couple of the pins to "cut it out" so that you can make adjustments to the fuel injection metering units.

    Mike

    As far as I remember this blue/red wire has no function.

    That's not even option on most vintage Lamborghinis, it's standard equipment ... :D

    Have one on my car as well. Maybe I'll figure it out one day?

    No rush.

    Isn't that the truth, Bob! LOL!

    Just look above at the photo I posted, there is a connector with a pink wire and grey wire w/ blk stripe that connects to nothing! It just sits there in the box looking pretty. ;-)

    The thing about this wire/connector is that it appears to have a mate right next to it (to the left in the picture I posted). I traced it down in the box and it connects to one of two gray wires on the GSM module.

    Confirms what I found. I just checked for any signal (V or Gnd), on this wire, it’s perceived mate, and between the two, and had no readings during ignition off, start up, idle, or when the first fans kicked in.

    The chassis that the box slides into has a little rust in the lower corner. Mine had the same thing. It's easy to take out. I put mine in the media blaster, primed and painted it. I found a high temp paint the same color... might have been made by Krylon but im not sure. Not sure how moisture gets to it but i have seen this several times. NAPA has a cheap china version of these relays (i keep one of each in the glove box as backups). The true Bosch ones i found and ordered online just searching with Google. Not sure where i found them but replaced all of them since they were old.

    Thanks Ken. I have replacements for all the relays except for the fuel pump ignition relay (the one with the fuse on the top). This relay is missing a plastic cover which I’m guessing has the part number on it. Any chance you know its P/N?

    Isn't that the infamous Italamec 12V 218 relay that always goes bad?

    I know people swap it out with a BOSCH relay. However pins 86 and 30 are reversed and need to be swapped.

    From what I understand, that Italamec relay was used in the Maserati Biturbo as well. They is a more modern version of it, where they use a "blade type" fuse instead of the "bullet" style:

    Mike is correct with the details of that relay..... i cant yet find where i wrote it down.
    Next week with the car i may have to open the panel and get to it again. I did find a place
    that i purchased some from (Bosch) but not sure which ones. Quest Components in California had a bunch. Give them a try.

    Anyway this fuel pump relais is for nothing, it's only a mitigation of the risk when you have an accident that the fuel pumps stop working when the engine is off.
    I have no relais, as soon as Ignition is on the pumps work, you can simply bridge the relais.

    Great engineering cross all the marques in Italy. ;)

    I've had the the newer blade style in my 84 for almost 10 years now without issue.
    Yes the Bosch relays can be subbed just as you've indicated.

    The more I learn about these cars the more I smile. I can’t count how many “unused” connectors & wires I’ve found ;)

    I’ll check out Quest and the MaseratiNet Store. I was going to call Texas Industrial Electrical. They list all the standard BOSCH relays on their site: http://www.texasindustrialelectric.com/relays.asp . The point of this exercise now is to have a few spares.

    Once we confirm this fuel relay is a direct replacement PM me your shipping information, I’ll order three, and send you guys one. If you don’t need this one I’ll send you a 332 019 151.

    The way things are going I should probably order a dozen 019’s and hand them out during the shows to ALL of you guys. I’ll be in Italy next summer (family in Tuscany) and will stick a few in my luggage for the EU guys too :)

    Thanks Again, Larry

    Resurrecting an old thread...

    Can anyone provide the Lamborghini part # for the Italamec 218 fuel pump relay (long discontinued and now impossible to find). The BOSCH relay discussed in this thread has a different pinout and won't work in my application.

    Check out this schematic Jason Jones and I developed. It shows the difference between the Italamec 218 and Bosch relay’s. I have the older version box in my ‘86 Countach, so it has the Bosch relay’s (protected by a separate fuse) instead of the Italamec units.

    Thank you, Mike. For those of us who have the earlier version of the box - and therefore the Italamec relay is needed - what options are available? I am trying to inquire with Lamborghini, but I need the part number for the Italamec 218, if anyone has it.

    The Italamec 218 is used in two locations
    1) S in the 1st image below (left side relay box - 1pc)
    2) No. 10 in the 2nd image below (right side relay box - 2 pcs fuel pumps)

    Image Unavailable, Please Login


    Right side relay box:

    Image Unavailable, Please Login

    The right side relay box image from the 5000 Maint book calls out a P/N 006311154, Bosch 332-0141-51C which I've never been able to cross reference (the "C" is the mystery). My car uses the Italamec 218 in these locations, noting that the center pin is not used.

    Italamec was purchased by Magna Electronics in 2007. Talking with them several years ago 218 is no longer available. The closest thing I could find was a Hella 003530041 4 pin w/blade fuse - Amazon $12. They are available with a 15A or 25A fuse. The 218 has a 16A fuse.

    Because the fuse is on the side, fit will depend on the layout of the sockets. If you do use this as a replacement it can only be used in the right side box (below), not the left side which uses all 5 pins of the 218.
