550 Fuse Board Options

The internals of the boards are completely invisible. No one is going to notice the differences except in rare cases when it comes to diagnosing power defects. I doubt Classiche inspections even look at the relay panels.

I have a board from @theunissenguido They are fantastic and incredibly well built. He was great to work with as well. Can't recommend them enough.

For Classiche, I have no idea. I dont believe they dig that deep, but visually his boards do differ on the fuse holders, otherwise there is no difference when dressed and installed.

Pictures below are his board installed, and next to old vs new

Ah, so you can see the circuit board material in the fuse area. Anyway, do the Classiche inspectors even remove the fusebox cover?

 

Actually before Im proven wrong, I mistyped, I have no idea how deep Classiche goes. I was thinking of what i have read for judging and shows.

 

You can see the fuse holders because I use bigger connectors than OEM. So, the protection covers cannot be put again. Some owners did have the patient to cut those protection covers in a way that they can be put back...in my view not needed.If you really want to protect those fuse connectors, you can use a ring of rubber (old bice tire) over them.

 

Do the protection covers have fuse numbering on them or do you have to use the Owner’s Manual for that anyway?

 

No numbering, but you can put a number yourself above each fuse on the black trim of the housing.

 

Do you make one for a 550 and what sort of time frame for delivery?

 

Dave you should have tagged him @theunissenguido

He has shipped a 550 for me…I can post up when I get it.

He has been attentive on communication, and the timing was very reasonable so far.

And FWIW my impression (so far) of what he is asking also seems reasonable.

I should add that my mechanic wanted me to use GT Parts in AZ. My car came with the original fuse panel in box which we would have had to send as a core or a rebuild BUT I’m not sure the one I had would have been suitable.

I trust @Aerosurfer and @Auraraptor as friends and their experience helped me go the route I did.

 

Dave, I sent you a PM, in Conversations.

 

Yes as alluded to I have @theunissenguido boards for both my 512TR and 456M.
The quality is a no brainer in comparison to OEM. I dont have direct personal experience with the other two options.

 

Tonight I got the new 550 board from @theunissenguido and it looks and feels amazing.

Super grateful - thanks so much.

Do not forget, use only the screws to put this motherboard in place. Do NOT use the white plastic washers that are on the original board.
Those white washers you use between the back cover and the housing for some ventilation.

When you want to protect the fuse holder connections on this board, you can use an old bici tire. Cut and glue it in smal rubber rings and put them around the 2 connectors for each fuse.

Elegant w the tire solution.

 

I did similar to the bike inner tube, but I used heat shrink tubing.

 

Not a good idea...when the fuse connectors get hot, those heat shrink tubing is going to shrink more and could break the solder points. Better a rubber ring that is flexible.

 

I’d also like info for a 550 board please.

 

I had mine done at GT Car parts, also looked at Scuderia Rampante, but they were very expensive and I couldn't discern the additional value for the price. I also added in the Ricambi fan wiring harness this year

 

That's my part.. thanks for your purchase thru Ricambi. If not installed yet, feel free to reach out to me if you have any questions.

 

I replaced the fuse board in my 456 GT with the GT Car Parts board. It’s visually identical to the original, and my car passed Classiche certification with the new board installed—no issues at all.
I’ve included photos of my original board (inside and out) and the new GT Car Parts board. I also replaced every fuse and relay during the process. In addition, I installed Aerosurfer’s fan wiring harness, which is very well made.
After 1,000 miles of driving, everything is working perfectly. No electrical issues to report.

My guess is they didn't even have a look at it.
