## Questions & Answers

**Q: How can you add/install this on an existing motorcycle horn?**
A: Do not understand why you would want too.  If your existing system need a relay due to high current draw the mfg would have added it when bike was manufactured.  It will not improve your horn or make it louder or change the tone.

**Q: How much does the relay draw? not the horn output rating of 80a- the low current input side.  (if it's under 10a i can use my existing horn button.)**
A: The relay draws well under 10 amps.  I use my horn button on a 2017 Tacoma with no problems at all.

**Q: How do you know which relay power cord is negative? And how do you hook that type connector to battery?**
A: As described in the third picture, the blue wire and the white wire on the harness are respectively connected to the positive and negative poles of the horn wire of the original vehicle, the red wire is connected to the positive pole of the battery, and the black wire is connected to the frame.

**Q: How do you hook up the button to the farbin horn wiring harness relay kit?  thank you.**
A: Connect one line of the button to the blue line of the Farbin wire harness, connect the other wire of the button to the positive pole of the battery, and the white wire of the Farbin harness is grounded to the frame. Thank you for your support!
