I finally got around to modifying my horn circuit a month or two ago on this new vehicle, as I have on my prior vehicles. It is my hopes that it will benefit others as it has for me. First let me start off by saying that on my 27 mile drive to work, that more than half of the miles take me through heavily wooded and unpopulated roads that are INFESTED with deer! I encounter 11 "problem zones" on the commute to my job that is literally "in the middle of nowhere". Very isolated. In fact, the last 7 miles is an access road that only the employees use. This goes right through the middle of a wildlife management area too. On my way home tonight I saw a pickup truck pulled over, with lots of debris in the road, and what looked like a deer on the pavement that literally "Exploded". My problem areas vary in length from 1 mile to 4 miles at the longest. After seeing this accident tonight, I felt compelled to share this with the group, and actually felt guilty for not. Do with it what you will. All I can say is that years ago I decided I'll never be without it. Have it on 2 vehicles right now.
The modification I built is quite simple. Once turned on, a 12-volt adjustable repeat-cycle timer "Chirps" my horn for a very short 50 milliseconds (adjustable). I have this set to repeat every 5 seconds or so (adjustable), almost about every 1/10 of a mile, more like every 3 telephone poles. I call it a "Chirp" because the horn is so brief, I think it's even shorter than a "key FOB chirp" when locking ones car. I often don't even hear it inside the truck, over the wind, road noise, blower and radio. It's not annoying by any means. It literally requires 3 wires... power, ground and one tied into the clockspring wire that gets grounded when the horn is pressed on the steering wheel. Our gen14s have easy access to this wire in the passenger kick-panel BCM. I have attached my wiring diagram of the 52-pin connector "J2" on the BCM, and what color the wire is (green/white, pin-18). Jpeg drawings of my wiring were too blurry, so until figure out how to post a clearer diagram, I've attached a PDF file which almost every computer can open. The diagram has the Timer mfgr & part number as well. Attached is a pic to this tiny timer connecting with 1/4" spade lugs.
Over the years I have seen countless examples how deer react to this chirp, especially when they are near the roads edge, thinking about crossing the road, and hear the sound getting closer. I have seen them freeze in place and the ears twitching like radar. Oncoming headlights simply don't give them a sense of something getting closer, but the sound gives them an entirely different sense of awareness. Actually I think just mere headlights confuse them. This has worked countless times in the daylight too. I refuse to have a vehicle without this modification. It gives me such peace-of-mind while driving in the dark in these 11 problem areas. Granted I have to switch it on 11 times on my commute, but until I got around to this vehicle mod, I had to smack the horn 175 times as briefly as I could on my way to work. Not a relaxing drive. This timer chirps short enough that I don't think I could duplicate it by hand. Now my drive if very relaxing.
I have one co-worker who has hit 8 deer over the years coming to work! And many more hitting several. Some ridicule the idea and say I'll wear out my horn, but I have years of proof to the contrary. Even if so, a horn every 6 or 7 years is still cheaper than a $750 deductible! Or a totalled vehicle.
