These pics are of a made-in-China horn relay for my 12V 54. The part numbers on the unit and the box yield nothing on the web, and the coil symbol shows to be an inductor--never heard of such a thing on a stovebolt. How do I wire this unit? I presume one goes to the horn button, one to the horn, and one to ground (?). The horn is an Amazon generic.

Contact #1 goes to horn
Contact #2 goes to horn button
Contact #3 goes to battery +

That "inductor" is the magnetic coil that pulls the arm closed connecting #1 to #3 when contact #2 is grounded. I have that same relay on my GMC.
