Bolt the horn to something metal or run a ground wire to it....find a constant 12V fuse it if you like, connect through a push button or switch and you got a honker /forums/images/graemlins/thumb.gif

I believe on most of our truck not sure on first gen's the wire is a medium green 12-14ga wire in the factory harness
