weird 2003 ford f150 horn wire

ok, i got it semi-installed :P too many projects right now! got th switch mounted on the left side of the steering column, and wired in. you were right... it was the blue wire on the brown plug. flip up, air horns, flip down, regular horns... now to wire in the relay, air solenoid, power to compressor, pressure switch....etc.etc... list goes on and on. thanks for your persistent help on this. i know i'm new here, but i appreciate it! you should've seen me hooking back up the battery after unplugging that plug under the dash... i said a prayer hoping the airbag wouldn't go off. i love airbags, but i hate messing with the wiring around them! thanks again. i'll post pics of the install when i'm completely done!
