I have a 2017 F150 with some loud angry truck horns. We've probably all seen this (www.youtube.com/watch?v=lv8wqnk_TsA) video of the nice secondary horn install in the GTI. It's been in the back of my brain for a long time, and I have been in my house for like 8 weeks now, so here we go!
Disclaimer: This is obviously not a big priority, so it's not gonna be a fast moving project. I added the trailer brake controller a while back and that was fairly easy, so I imagine I'll be digging around there for some nice switched 12V power (perhaps off the lighter plug? We'll see)
I bought this horn (www.ebay.com/itm/12V-Loud-105db-Motorcycle-Car-Electric-Bike-ATV-Horn-replacement-with-Bracket-US/193074643965?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649) for a scooter. It's cute and high pitched compared to the truck, not to mention a bit quieter. I had some JD1912 relays lying around (30A) so I'm gonna use that. Will give me flexibility whenever I find control power for the switch (can be low amperage and key switched easier, though I briefly considered power through the switch).
Here's a quick and dirty wiring diagram on the back of a beer carrier:

Here's the mounting location and where I found to fish the wire through:

oh man the truck is dirty. that's embarrassing.
Figure I have to:
finds control power for the switch (very open to suggestions)
mount the switch (got the perfect spot)
fab up a little mount for the horn itself
find a home for the relay
wire 'real' power to the horn (I'd like that to be switched, too)
vacuum the truck
pretty it all up
