Hi and thanks for using 2CarPros.
I'm not sure, but in the picture it looks green. I can only see a portion of it. If it is green with a red tracer, it goes to the horn switch. Take a look at the schematic I attached.
Now, with the key on, if that is the wire for the horn switch, it will always have power. Ground is provided by the switch to sound the horn.
To check for power, use a simple test light. Here is a link that you may find helpful:

Let me know if this helps or if you have other questions.
