Hey all - I am adding an air horn to my 2013 Sierra to make my truck alarm more effective; my driveway ends 30 yards from where I sleep and some yahoo put a brick through my window last year at 2 in the morning; I only heard the stock horn going off because I happened to be up to pee. I'm putting it on a rocker switch so I can still use my stock horn when I'm driving.
I've been studying up and it seems like they really packed things into the front end, making it tricky to even *get* to the horn wiring; is it true that I can get the horn trigger wire from the harness under the steering column? I found a wiring diagram for adding remote start to a 2012 that claimed it was a tan wire; I also found a diagram claiming it was available in that harness but that was for a '95.
Any ideas? I'd love to be able to tap into it there and not have to take half the front apart!
Many thanks, guys - I really appreciate it!
