Hey guys
I ordered a new louder horn and it only has a blue power wire and the unit grounds when you bolt it in I guess
the current horn has two wires with identical plugs any idea on how I would wire it so I have 24v to the new horn?

Wire 26a is 24+ power to the horn, wire 25a is the horn button, which grounds the circuit. You need to figure out how to make the horn button ground to activate the horn.

Use a meter to check which wire has power while someone is pressing the horn button. Make sure the switch is on.

I figure it would be easy
so are both wires power?
i tried testing them with my meter individually and got nothing when pressing the horn but old horn works fine

It seems like you need to insulate the horn from ground when you mount it. Connect 26a to the wire on the horn. Connect 25a to the horn body.

A relay in the circuit will work also. Wire 26a to one side of the windings as well as one contact. The other side of the windings is connected to 25a. The other contact is wired to the single horn wire. The horn is grounded through its mounting.
The horn button grounds the relay when pressed, sending +24 to the horn.
