Hi I am having difficulties in finding the Location for the Head Light Fuse and the Hi Beam Fuse on a 2021 E-350 with the 7.3 Godzilla. Questions:
1. Are there Fuses for the Head Lights and the Hi Beams?

I have been Through:

• Owners Manual.
• All over the internet and YouTube.
• I have access to Technical Manuals at our Local Library.
• Even went into a Ford Dealer (Parts Technician)

I am stunned I am unable to find these 2 Fuse Locations.

Stlhdr
Any help would greatly be appreciated.

 

You may not like the following answer, but there is always the tracing of the wiring back from the high beam color wire back to where it gets it's power/ When a schematic is not available ,this is what we need to do. It does take some time and patience, but it is a sure way to find the power supply end.

If you can't or don't want to get this involved, you might consider having a qualified shop do the job.

 

Totally understand.. I am also thinking about turning the lights on and unplugging and re-plugging the fuses until the lights go out andor the Hi Beams go out. not sure if there would be repercussions from this. I am thinking it cant be much worse than pulling the battery. Getting ready to pull some the Dash Panels and see what I can see. I am installing a Light bar. When I did my DMax. I got a Fuse Tap and replaced the original Fuse with the Fuse Tap... Was a really Clean install. While I am in the Wires and Locate the Hi-Beam wire. I suppose I could tap directly into that.
It is always good to know where the Head Light and Hi Beam Fuses are though.

Thx Hanky
Appreciate taking the time to respond.

 

There is something of which you may not be aware and that is late model vehicles use quite a few modules including lighting modules and adding addl loads may cause the module controlling the lights to shut down thinking there is an overload in the system. You can try it, but if you have light problems up the road, you may be looking at a new lighting module.

If you go directly from the battery , the charging system only knows what was tied in at the time the vehicle was built.New vehicles don't allow us to do what we did in the past.
There is no harm in getting other opinions from dealership service depts.or experienced shops.

 

Light bar is/will be Directly wired to the Battery with a relay in between. A Tap from the Hi beams triggers the Relay on and off. Power for the Light still comes directly from the battery.

I am definitely not a guru on Auto Wiring so I can't talk to intelligently on the topic.. This is what I did on my DMax 2015... knock on wood.. i have not had any issues to date. Understand what your saying about about the New / Late model vehicles... I am old enough to remember when I changed Points, condensors and distributor Caps.. I understood those days better.
