PO removed original horns and installed a dashboard button. I am trying to install new horns, a new horn relay, and new wires. May I ask for some help please? Which wire goes to which post on this relay? H=horn; B=battery; S=switch. Thanks!

Thank @Coolerman for his efforts on building his website, and buy your wiring supplies from his online store.

Item 12 is the horn relay near the bottom left shows H: green/white trace; B: green/yellow trace; S: green/red trace The S: should go to ground when the horn switch is closed. B: should be hot all the time.

To clarify, all the connectors are gone. And all the wiring is gone.
Wow, three posts in and the story is starting to come together.

Whatever the source of the relay, the manufacturer should have a schematic with the information you seem to be seeking. Otherwise, pry the cover off and figure it out.

Thank you. To be clear - the PO removed all of the wires and connectors. I have to run new wires to the fuse box, to the switch, and to the horns. If you could tell me which wire goes to each tab, that would be useful.
