Thank you, I'm sorry I did not see this post. Have been under the weather lately, I do have the horns and the proper mounting yes. I appreciate your post. Mine is a 38 Standad Coupe. The horns each have ONE wire, they GROUND to the frame on a "lip" that extends out a few inches and has three holes in it, that match the three bolts that are still with the horn. They do ground to the mounting piece. Must be "ground off" top of frame, bottom of horn mount, for GROUND. They are supposed to go together, "a y" to a single lead to the relay. Also, like an other post here, I have NO relay. I am installing one, and then the lead goes to the solenoid. One of the wires go to the "horn rod" and light switch housing. The rod goes through the middle of the housing, spring loaded, and when you push the horn button inside the car, it grounds..and that's supposed to blow the horns. Haven't got them hooked up yet, but I will post how it torns out so maybe someone else could use the help. Thanks Again, Old Fred
