[Elantra GT] '05 GT Horn Wiring Question

[Mark Hankins - Florida Incorporators, Inc.]

On my '02 GT, I just yanked the horn and spadelugged the new FIAMM "El Grande" set of two horns in its place.

I went to do that on my '05 GT, and the horn has a modern connector with a couple of conductors in there ... and I'm not sure what all they do, and I'm concerned that the "chirp" for the alarm activation might be a secondary function of that little horn unit, so I don't want to disturb that. 

Has anybody replaced the horn on an '05? Advice?
