Hey y'all,

So I know this subject has been touched on before, and I myself have brought it up in a different light in the past, but I'm back at the idea of relocating the factory horn and wires so that a thief can't simply use some extended wire cutters to snip the horn and then do whatever they want to the truck with no audible warning going off. Im curious to see what people have done and to pose two scenarios i have thought of as solutions:

NOTE: I plan to install perimeter plus security module as well to make the truck super sensitive to random people messing with it.

Option 1:
Relocate the factory horn to the side of the grille/radiator so that the cables are not as easily reachable, reinforce cables with metal braids of some sort, and splice a connection off the wires that goes back under the hood to my secondary much louder horn.

Option 2:
Relocate the factory horn into the engine bay and move cable with it, splice connection in engine bay to run OEM horn and secondary horn.

Option 3:
Leave factory horn in current location, reinforce cables in front, splice into horn wires in wiring harness farther back to power secondary horn.

The biggest issue I currently see is that the wires that feed the horn in the front are part of a thick wiring harness and split off with about 6 inches of length near the horn. Due to this, I see no way of achieving total security to the wires powering the horn without un-braiding the wiring harness and pulling out the horn cables farther back.

Does anyone have schematics for this harness and if there's a way to pull off those cables farther back in the engine bay?

My preference as of now is option 3 and finding the horn cables in the wiring harness further back in the engine bay so i can just split off them there and run to the second horn. I like this because if a thief thinks he/she managed to cut the horn, little do they know there's another surprise waiting for them when the alarm does go off. I also think this would deter them to leave quicker since they wouldn't expect it and wouldn't know where to find the horn and hopefully ditch and run.

Thanks y'all in advance!

I have also actually planned to do Option #3. I have the second horn and figured to just splice in to original horn wires when weather gets cooler (this week actually). Just curious if the current (no pun intended) fuse can handle a second horn. I can't imagine that a horn draws much power.

Anyone else have thoughts on this???

From what I have seen, depending on the secondary horn, you might be able to pull it off. I wish we could get the wiring diagrams for that harness but they cost around $100 lol

In my case the horn I am using has a little compressor that is activated by a relay which requires very little power. Thus for me I would just hook that to the horn leads and then power the relay straight from battery.

For reference, here is my horn: https://a.co/d/jlUNqkh

I did option 2. I moved the horn into the engine bay area... there is actually a good existing mounting point on the driver side of the fan shroud. It may appear flimsy, but it does the job just fine. I ended up extending the factory wires by soldering extensions to the existing and re-terminating the connector. It is the connector that they get to, to unplug the horn... not the wires.

The one I have also has a little compressor. Honestly, there is a ton of room behind the hood, I think l could get a body in there!

Here's the one I have - https://www.amazon.com/gp/product/B07WDZYSFS/?tag=fordraptorforum-20

Nice! Just curious though, are you not concerned someone might cut the cable for the horn leads through the grille if they know that those two wires are meant for the horn?

Maybe I misunderstood you but it sounds like you cut and extended the wires from their original location in the wiring harness so that the horn could be in the engine bay. My only concern is that a thief might know those wires are for the horn and cut them anyway.

Did you not want to unwrap the harness and move the joint where they split off from the main harness further back?

Mine are in loom and routed along with the other loomed wires. It would be a guess at to which wires go to the horn as it is not obvious at all.

There are two existing holes on the shroud. I just mounted each horn on its own hole. No drilling and been fine for several thousand miles.
