If you don't have the horns--- you wouldn't understand
I have Shockers on my F350 with dual compressors. The compressors are frame mounted inside of plastic battery boxes. Works great.
When your towing a 40 ft. + 5th wheel and a hotshot driver pulls in front of you then you will understand why you need air horns.

Sometimes horns louder than stock are needed to break through the idiot barrier. Not kid stuff pulling out in front of loaded trucks. And in this area it is mostly the farm trucks with the ***** hanging off the trailer hitch. Lot of cows in this neck of the woods.

I think the upfitters look cool, especially since they are now mounted aircraft style overhead. However, the only use I ever had for them was the diesel high idle, but it seems that's now a built in function?

I will look for that in the manual later. I believe it is only for the Cab/Chassis where items such as hydraulic pumps and heavy draw on electric are necessary.

Idle Control
Your vehicle may have a factory option for
a stationary elevated idle control through
the upfitter switches in the overhead
console. This allows the operator to
elevate the idle RPM for extended idle
periods, as well as aftermarket equipment
such as PTO operation. You must configure
this feature even if ordered from the
factory. See your authorized dealer for
required upfitting.

Upfitter switches
The switches are a great addition. I use mine not only for my air compressors, and air horn regulator but high idle and trailer camera.
My 200 psi compressors are fantastic for the the air horns but also for my air ride hitch, air bags, air to change tires, air for my air bottle jack and anything else you can come up with.
Great add on for any truck. Not just one with a bulldog.

Thinking further about this option I can imagine that the "upfitter module" would be required as well. It controls auxiliary functions to ensure the correct parameters are met for among others safety reasons. Some require transmission in neutral and parking brake set and I would believe high idle would require at least one of these if not both so that a high idle switch could not be activated while in a line of traffic for instance and then have the truck jump ahead in a pedestrian or another vehicle. Even a truck left in gear with the parking brake set could take off on its own if the high idle was activated. This is all conjecture on my part but these simple safety standards are bound to have been enacted by brains much stronger than mine.

The upfitter module or upfitter switches? Any way that is good to know. I would hope there would be a parking brake defeat as well. My 7.3 runs up to 1200 rpms without the parking brake when cold but kicks down immediately on touching the actual brake pedal which is required to shift out of park.

https://www.fleet.ford.com/truckbbas/non-html/Q-218.pdf Relevant. What it's actually looking for is a voltage, not a resistance, which means you could (I believe, though I intend to test this) use an arduino (or similar) and a MOSFET to control the SEIC. I've got clever ideas as to how to use that, but hoping to combine it with a "remote start" to give me the ability to hold a deep-cycle battery at charge, would let me keep heated blankets running overnight without idling the engine non-stop... we'll see if I actually do that or not.

For the hundred and some dollars, why not have the option to do something later? If anything, it's worth the conversation starter it makes with your passengers.
