Hopefully this will show where I found the CJB info.

 

If that's the case, then it sounds like the answer to the OP is "it doesn't exist".

The owner manual for a 2003 Ford Excursion lists that as the "Passenger compartment fuse panel / power distribution box" (page 188 - 192 of the owner manual).

 

Yes Robert, the pic you posted is the fuse panel below the dash.

 

Actually, where I got that photo claims it is the box under the hood.

 

You're adding a lot of confusion to a simple answer. On the OP's 6.0 the CJB is the fuse/relay panel under the column, by the drivers knees.

 

Missing my point (and Stewarts)...it's a fuse box...nowhere in the documentation available to a typical owner nor the Ford parts site call it a CJB.

Newbies reading this thread are going to start looking for these parts and not find them because someone is choosing to use a little known nomenclature to describe something commonly known to everyone from the engineer who designs these things to the (often) mindless parts people at dealers and shops, and will just perpetuate the confusion.

It's a fuse panel. Plain and simple. I'd argue that walking around calling it a junction box will cause much more confusion when someone tries to find that part on a web site or at (one of the many) clueless dealers and shops.

 

An example of this confusion...web sites (that people seem to think are ALWAYS right) use the location known to 2000 model years to put up as a location of the diagram for a 2003...even screwing up the diesel vs gas description.

 

'02 V10 under hood, where the early ones have a fuse box. Just a couple relays or something here.

 

Ford service manuals calls the interior fuse box a CJB. The underhood fuse box is called the BJB, battery junction box. Has been this way for many years.

 

My 03 7.3 box:

 

Yet the ford parts site lists it as a fuse box, as does the owner manual.

How many owners have the service manual vs. the owner manual, and how many (mindless) parts people use the parts site (that lists it as a fuse box)?

 

Sorry I'm Late, I was detained by a 03 Excursion 6.0 Diesel Shut down in the Middle of the High Way at Highway speed No Start no Crank issue but, I rode a Tow Truck with my Excursion and got here as soon I could! As Usual


Anyways,
My 2003 Excursion 6.0 Diesel Owner's Manual Says the "Fuse Box"
Located Left most under the Steering Wheel is called the;


Fuse Panel / Power Distribution Box






However,
I think the Central Junction Box (CJB) is inside the Passenger Kick Panel


Along with the Owner's Manual indicted;
Fuel Pump Shut-off Switch (Reset Button)

 

Yes, the fuse box is referred to as the Central Junction Box in service manuals. Couldn't tell you why they don't just call it fuse box to keep it simple. If you're having problems withthe radio and power windows then I would suspect a bad accessory delay relay. They're cheap to replace. I read one post where the guy took it apart and cleaned the contacts. I've tried that with the power seat switches and it didn't work so I would just get a new one. It's called K126 on the attached diagram. Good luck!

If you are asking about what causes the windows and radio to not work in some junction box, I found out it was the instrument cluster. There is some kind of relay or something in there that controls the windows, overhead reading lights, stereo, mirror controls, etc. Only way to fix it, at least what I've found is by replacing the instrument cluster and having Ford program it for your specific vehicle.
When mine acts up, I usually take both hands and hit the top of the instrument panel area and it comes back on and everything works like it should.

 

The Central Junction Box is the fuse panel under the dash.

It is important for everyone to know this term, because even the lowly Haynes manual (with it's crappy wire diagrams) calls it a Central Junction Box.

Every source for electrical diagrams I've ever seen calls it a CJB, so I'm not really sure why anyone is confused : Haynes, Chilton, Factory Ford Wiring Manual, Autozone online wire diagrams, etc...
