    The dreaded day has finally arrived. Went out to start the 87 3.2 yesterday and got the strong starter turnover but no start. Got out and wiggled the fuel pump connector to the fuse box, and she fired right up. Figure I might as well do it right and change out the whole box. I see three options out there: The GT Parts rebuild, the Dave Helm version, and our own Guido, though I am having trouble getting in touch with him.
    Any pros and cons on any of these three options would be appreciated. I've always read good things about Scuderia Rampante, but the price is quite a bit higher. Is it worth the difference?
    Thanks for any and all advice.

    They’re probably all good but I think for sure the Scuderia model is on another level. I’ve spoken to people that said the GT one can take a long time to get back. Dave Helms told me that the T fuse box had around 17 different points of failure and he addressed all of them in his build. But yea, it’s pricey.

    Guido gets my vote. It’s a pain to do all the wire mods but I think it’s a great board and a permanent fix. When I took my old board out and examined the back of it I was amazed it worked at all.

    Yeah, I'm about there now. I guess I'll keep trying to find him.

    could you expand on the wiring mods? Not quite sure what I’m getting into here. Thanks!

    There’s a few circuits that Ferrari routed thru the board that are not fused, so the fuse board is being used as a connector. So those connections can be made outside the fuse box. Simple but I’m sure it helps cut down on heat. Did you read the install manual on the site? Like I said, pain in the back to lean over car making terminal ends for what seemed an eternity.

    haven’t seen an instal manual. That would certainly help. Can you point me in that direction? Much appreciated!

    I used GT Car Parts, Ross Young 623-780-2200 and had a very favorable outcome. We mailed him the board (like a core) and he sent back a new rebuilt unit with better silicone board and connections. I also had him replace all the fuses and relays and the white plastic connector bar you show in your photo can be bought to fix the burned connection points. Super knowledgeable very professional!

    Thanks for all the replies. I sent mine to GT this morning after talking to Ross yesterday. I'm sure Guido's product is completely first class and a giant upgrade, but the thought of reclipping all of those wires just didn't appeal to me, though the gained advantages are apparent.
    Some new clips and a new white connector for the inside connection are also in the works.
    I was amazed just how well things tended to work in my car after taking the old board apart for an autopsy. Complete de-lamination of all layers and several slightly burned solder joints were apparent. And of course, the fuel pump connection was complete toast.
    Here's hoping for another relatively trouble free 33 years!

    Get in touch with @stekkefun4 as he has the fuse boards also from Guido on his website.
    www.redbaycars.com

    IMHO the fusebox of Guido is the better choice. it replaces the whole fusebox. Else you will stay with a (partially) delaminated fusebox. I have one too and I got rid of some other stuff too. sooner or later you will need to change it anyways.

    After much discussion with the people at GT, I can't figure out how I would still end up with a delaminated board. They told me the board is made brand new from a more modern based material, unless I'm missing something. As mentioned, it was the thought of having to change all those connectors with 65 year old arthritic hands and eyesight that ain't what it used to be that made me rethink the box from Guido. I'm sure he makes a great product, but I was looking for more of a "plug and play" option. Thanks for your advice. Who knows, may end up there yet!

    Ah ok then you are right when you get a new fuseboard. I though you mentioned the additional Fusebox placement which sure helps with these burned connectors, but the old Fusebox stays in place. If you retire also the old fuseboard its perfect!
