1. Amber running lights — raptor grille lights
2. LED off-road driving lights
3. Rear/reverse lights
4. Factory/Train horn toggle
5. Air compressor
6. unused

I just wish I could find custom decals for the switches. The guy mentioned in some threads here years ago doesn’t do it anymore. eBay sellers don’t either.

 

1. Amber front fog lights
2. White front flood lights
3. 2LO Mod
4. Unused - eventually will be for air horn
5. Unused
6. Unused - eventually will be for triggering the air compressor relay that will supply on board tank, air bags, and air horn

 

Note that switch circuits 1 - 4 are each fused at 25A and all are “Hot on Run”.

Switch circuits 5 and 6 are fused at 40 A each and can be group-configured as “Hot on Run” or “Always Hot”.

#1 for the snow plow
#2 for the light bar on the roof (also for plowing)
#3 might end up being for more powerful backup lights

 

#1 SEIC
#2 2wd Low mod

 

What is the 2wd low mod that u guys are talking about??

 

Used one of my upfitter switches to turn on and off my onboard compressor for my airbags.

 

You can use one of the switches with a relay to disable the locking of the front hubs. This will keep the transfer case in low but not put you in 4wd. Nice for backing a trailer or other things at low speed that don't require tons of traction. Keeps from putting unneeded strain on the 4wd sysem.

 

Have y'all seen the updated 2022 manual where the circuit amperage ratings have changed?
This is pulled from the 2022 manual on Ford's website: https://www.fordservicecontent.com/F...US_04_2021.pdf

 

Have a switch pro and the upfitters on mine.
upfitters are used for high idle, ham radio, horn toggle, air compressor. 2 others are wired to the switch pros to flood the front or rear.

switch pro runs my light bar, amber and white fogs, rock lights, amber and white rear lights, amber white strobes, and air horn.

These switches beg to be used

 

Pretty much anything your imagination can come ip with.

 

Man, why did Ford make these wires so hard to get to?

 

On my 18, they were very easy to access just forward of the firewall drivers side. Easy ground right there also. Are they different on the 21s?

Inside the cab, pass through wires, passenger side kick panel is what I assumed he was referring to. They weren't very long in 17-19 and it sounds like they ere even shorter 2020 and up.

The relay box location moved to the passenger side on the 20+. That's an improvement imo, but it could have made the wires harder to get to. That could be what he's talking about.

 

in MY20 they moved to the passenger side of the engine bay, closer to the pass throughs.
