Trying to hook up the horns but ran into a confusing situation, (for me).
Disconnected the oem horn, found what i thought it was the positive and negative on the horn, if i remember correct my 05 had only one wire which makes the only connection positive and the ground gets it from the frame.
On the X, it has 2 connections, but when switch is open both of the connectors have power.
need an electrical guru to chime in and guide me like you would a 5 year old
Thanks in advance
 
First I'm not a guru so take my advice or wait for someone smarter.

My 06 has 2 wires, not sure on the 05.
Plug them both in and it should work. If not switch them to the other post.

The switch grounds the horn, power is always on, IIRC

That makes sense, now, the horns that i got have only one wire connection, how to i go about connecting them since they get the ground from the frame?
 
If they are more powerful horns then they probably need a relay. Power the relay switch with the horn wires, and power the relay from the battery, via a fuse, and then to the new horn.

Place a relay in energized by the existing wires then run a positive wire to the relay contact to connect to your new horn
 
Definitely will need a relay. As already mentioned, the ground is switched. Use the two connections on the OEM horn to switch the coil on the relay. Run a positive from the battery through a fuse to the relay then from the relay to the horn. You’ll have to ground the horn too...either from the battery or a good ground point on the frame nearby. As motorcycles are so short, I would just run it from the battery.
