Nissan Cube Sports Horn for Versa

[versa09guy]

Hi, I want to upgrade the horn in my 2009 Versa 1.8S. I opened up the hood to see only 1 horn from the factory, even though the manual states that there should be 2 horns. I want to replace my 1 horn with the two nissan sports horns for the cube that are sold through nissan. I was wondering if anyone knew if these would work in the versa without a relay? How many amps do they draw?Does my versa have the wires for 2 horns, even though there is only 1 horn by any chance? Thanks for the help!
