Does anyone have a fuse diagram for a 2023 Ducato, particularly the dash fuse box. All diagrams I have found so far are for previous models which show 3 rows of mini fuses however mine has only 2 rows. (The handbook fuse section helpfully says - fuses must be changed by a Fiat dealership - changes by unauthorised 3rd parties could cause a serious malfunction.)
 
Any good?

thanks very helpful.
I tried a fiat dealer in the uk and Fiat in Italy...neither would supply the information as it was dealer only.... not much use if you are not near a dealers and need to check fuses.


Do you know if the engine bay fuse biy remains unchanged from the 2023 models.

thanks again

You’re welcome. These are screenshots from the owners manual I downloaded from the Fiat Camper website - IIRC I had to register to do it:

Hi, Fo2 is a 50A fuse and supplies power to the heater (Glow) plug relay, f11 supplies power to the coil of the same relay.

I too cannot find any fuse info relating to the latest Ducato 8 series. Did you manage to find any more specific info? I will be hardwiring a dash cam soon so will multi meter a suitable fuse to piggyback onto. But like you, I would like to know the what fuse does what for future reference. The diagrams kindly offered by Orion post #2 have a different layout to mine.
 
Has anyone progressed this yet? I’m about to add a dash cam and wish to tap from an ignition fed fuse. My under dash fuse board has two horizontal rows of fuses, unlike the one in post #2. Also which end of the fuse will be the “live” end so I don’t tap off an already fused feed.

If you have a multimeter it should be relatively easy to locate an ignition fed fuse. Are you using a piggyback fuse holder? Don’t think it matters which end is the feed if you are.

It does matter. If you get it wrong then you will have 2 fuses in series.
This will not matter so much if you have chosen a relatively much larger fuse to piggy back.
You really need the fuses in parallel and just sharing the positive feed to them.

Make you right there. Didn’t think that one through did I! A quick check with the multimeter should sort both issues out though.

I’m surprised that there isn’t any information online about the Ducato 8 dashboard fuse box.

Since Introduction of X290 and Fiats online system (co CDs) there is very little Fiat information in the public domain. (though x290 fuse info is available)

Poking around in the fuse box of an A class is a bit cramped when there’s no drivers door. I’m not as supple as I was!
 
Just an update on what I've found.
Using the diagram from Orion in post #2 with the ignition off. All the fuses on the left hand side (would be the lower bank in the vehicle) are live so no switched feed to these(!?). All the fuses on the right hand side (upper bank in the vehicle) are not powered. I chose F49 to take a feed from. I discovered that the input to the fuse is the left hand pin of the fuse (lower pin in the vehicle). The adapter I have is "L" shaped and the internal connections are such that I cannot insert it into the fuse holder due to the lip of the fusebox getting in the way. So I'm going to have to get power from somewhere else, probably one of the dash mount 12V sockets. Not as neat though.

I hope others find this useful.

Could you not get a different piggy back fuse holder that would fit?

It would seem that the adaptors I have seen have the take out cable at the opposite side to the power in pin. It’s the easiest internal wiring layout within the plastic and is the same as mine.

Just had a look at what I did on ours. Looks like I also chose F49 but the piggy back holder I used has just about long enough reach to miss the lip around the fuses.
If memory serves me right, I could not use the one supplied by Nextbase for the dash camera power supply but I had some others in my stock.

Hi Steve, did you find a way round this ? I'm in the same situation, attempting to fit a hardwired dashcam kit ( to a 2023 Ducato) and the piggyback fuse holder fouls the fuse box lip. My current thinking is to use a fuse extension to allow me to fit the piggyback, something like this -> https://www.ebay.co.uk/itm/20453292...pid=5339023013&customid=&toolid=10001&mkevt=1
