S650 Mustang Fuse Box Diagrams

[roket]

a comprehensive list of all the fuses as of June 11th, 2025

some important notes:
1. there are no engine running switched fuses anywhere
2. all relays except the one to power the cooling fan are non-serviceable and built into one of the fuse boxes

BCMC/BJB (Body Control Module C/Battery Junction Box)
Engine bay, cover has 2 clips that press in and 2 bumps you bend the cover over, then lift the cover up

Thank you, I couldn't read the numbers in the "Manual". Drove me nuts!

 

[DCBuckeye]

I'm a bit of a dullard on this. Which fuse in the passenger box would folks recommend tapping for the on/off of an audio amp? Something that's "on" only when the car is on. 12? 31?

I am also interested in this....

 

[Bandiz]

and I would like to share fuse panel locations for S650 if someone will need it..

Engine bay fuse panel



Interior fuse panel




I hope that will be useful info

 

[8915GT]

The BCM fuse list does not match what in my GT or the owners manual, where did you get this info or is for different model?

based on your vehicle listed in your profile, you're trying to compare your 2015 Mustang BCM fuses to a 2024 Mustang BCM.

LOL, I never updated my profile, I own a 2024 GT and the BCM fuse on the list are worded differently than what is in the manual. My manual matches this.

ah, okay. i got this diagram and wording directly from Ford's service website, but i did simplify some names for compactness

 

[roket]

The main post has been updated to include the fuse layouts for the GTD, including its unique 4 additional fuse boxes

I tried to compare the fuse list on this thread to my fuse list, but it's too much work to check 1 by 1 if everything matches. But all the random fuses I checked matched with the ones on this thread.

Can you give me an example of things that are different in your manual so I can see if it's different for me too?

Thanks to everyone who has contributed information.

Here's my contribution.
Information collated as PDFs, so they can be saved and referred to offline.
I'm old skool, so I like to have hard copy I can work with by the car.

I was sniffing around months ago for an IGN feed for my front camera project.

The only physical differences I found between the information and actual BJB fuses was the * SHOCK HORROR * absence of the 10R80 related fuses BJB-67 and BJB-158. As per my sig, I have a RHD 6-Sp manual.

Didn't check the BCM fusebox... our RHD accelerator pedal makes that difficult, and I didn't need to do it at the time.

Sorry, fuse tables are pre-GTD update and GTD not included.

Note two versions, A4 (most of World) and US Letter versions.
Hope this helps somebody.

Which fuse did you end up using for a switched source?

 

[roket]

updated this once more. fixed some minor errors, like one fuse being specifically for RHD late production 10R80 vehicles. also added info on when each fuse is hot, and if it depends on a relay or relays, which one(s) for it to go hot.
@5.0ALM in case you want to update your guides
