Is it working? Have you tested for voltage at the horns with someone pushing the button? Do you have clean grounds at the horns?

The horns are supposed sound at the same time right? or do they sound one right after the other? | | | | | Joined: Dec 2015 Posts: 2,063 Big Bolt Forum Moderator | | Big Bolt Forum Moderator Joined: Dec 2015 Posts: 2,063 | as stated above, they should sound at the same time, sounds like they are not getting enough current to sound them both. Could be a bad ground or faulty/weak relay.

The relay mounts to the center part of the trumpet horn bracket in the orientation shown in the above picture. Your hot wire comes directly from the battery post on the starter to the center tab. The passenger side tab connects to the hot wires for both horns. The driver's side tab connects to the horn button. If necessary I'll take a picture of mine & post it.
