    Hello All, in my continued effort to upgrade my relays and fuses in my footwell panel with brand new ones – I have gone ahead and labeled what is currently installed to make it easier for me to see what is going on.

    Question to the group: Is there a reason why the previous owner would put 25s in-place of the 20s, 15s in 10s etc?

    Was the manual for the 1994 model amended? or is this a case of the previous owner going, "yeah, this'll do!"

    I would like to replace these and with the proper fuse for each slot.

    Thanks for any clarity on this.

    Where did you get the values from, Anthony? F348 Spider Owner's Manual? Generic pdf Workshop Manual? Do they agree?

    I believe there were one or two factory-recommended upgrades on the F355, but there seems to be quite a few differences on your F348 photo. The later models may have had some differences due to engine management changes and the spider may have had an increase in fuse power due to the addition of the Window Control Unit (?). Did the spider have a mousetrack seatbelt? I don't think there would be any changes for this, however. Most of the mousetrack seatbelt stuff ran directly off the battery.

    Yes, my 1994 Owners manual that came with the vehicle and it does have the mousetrack.

    To me, it sounds like a bit of "creativity" on the part of the previous owner, but I defer to the 348 experts.

    The generic workshop manual (which includes 2.7 engine management, but has no spider/no mouse seatbelt details) agrees with your Owner's Manual. Oddly, I have a decal on my relay panel cover which includes fuse amperage, but in one case lists an equipment item which is not even applicable to one of the fuses, so it's hard to know how accurate some references are.

    Some of the decal values make sense:

    A spider doesn't have rear window demisting, so a smaller fuse is ok (for heated mirrors)
    US cars have combined front fog/daylight flashers, so it makes sense to go to a larger fuse (than the generic workshop manual)

    Was there a larger RH radiator fan on later cars?

    Oddly, the parts manual only lists variations for RHD/LHD and 2.5/5.7

    Based off of my mocked-up chart above and the back of the footwell plate:

    #10 & #22 – looked like just a reversal. I swapped them back.

    #1 & #3 – I will go ahead and replace each with their respective fuses - should not cause an issue.

    #15 & #17 have me concerned. Manual states to use a 20 and plate states a 25. Previous owner used a 25. Would make sense for both LH and RH fans. I was even puzzled when I read that in the manual? Only one 25??? Will need to do a little research on this before I change anything. And as for #15 – again, I'll do some research.

    Don't assume that all that is written on the decal is all that is powered.

    For example:
    Fuse 1 (cigar lighter) also powers the courtesy light time delay module. Even so, 25 seems high. I wonder if the previous owner was running some high powered accessories from the cigar lighter.
    Fuse 3 (daytime flasher/fog) also powers interior lights and glovebox power outlet.

    15 is the smaller oil radiator fan. 13 & 17 are the water radiator fans.
