I was thinking about installing a set of Fiamm dual trumpet electircal air horns.

Do you really think I need to use a relay?

I had them hooked up on my truck and just spiced them into where the stockers were wired and they seemed to work fine?

Correct me if I am wrong, but our 4th Gens have 2 elctircal horns in two separte locations correct?

Any thoughts?

Please post up
Thanks
