I don't know where the factory mounts it, but if you find it cut the positive wire going to it and seal it off permanently. And "if" you have the up-fitter switches, run a wire from a switch to the existing alarm, this way you can use it when its needed.
My truck didn't have one but I did install an after-market unit and wired it to an up-fitter switch.

Bonus: Was at a festival Sat and had to get into the area to load up, drove thru the crowds that were walking the street and hanging around after close. Flipped on my #3 and the alarm comes on, catching their attention, sure helped me get thru the crowds easy, so it works going forward or in reverse...

When running upfit wire directly to backup horn is there a need to add an inline fuse along the way?
I definitely like the idea of activating the horn with a flick of a switch rather than attaching to reverse light.....

No fuse is needed from you, its already in the circuit along with the proper relay.
