Does Chevy use two different horns in the same year trucks? My '04 2500HD's horn sounds as lot different than the horn in an '04 2500HD base model. I've seen parts sites listing a high note and a low note horn- high note is supposed to be p/n 89046917.

Anyone know which one goes in the NON-base trucks, and what the part number is for that?

Base model is one module and the upper level models have 2 horn modules. The wireing is there, you just need the module. I *think* on the base model, it's only a high note, so you will need a low note.

Don't mess with that, get you a set of air horns.
