20004 jeep grand cherokee fuses

[ron harris]

Does anyone know what the 3 unnamed 50 amp fuses (execpt for JP power) in the engine compartment of this vehicle supply or feed. The 4th one supplies the running lamps. The vehicle operates without them. less some minor items. By the way it is a 4.7L. V-8. 2WD. Any advice is greatly appreciated.

I found this diagram with a picture on the web. You can click on it then use your control button to blow it up more if needed.

Looks like one may be a spare and the other may be for glow plugs on a diesel. (I didn't know they offered a diesel)
