Review: Quality harness with relay and wire loom - Bought this for a Hella horn setup on a Gen 11 Honda Civic. I did use the relay that came with the Hella horns but the clear relay that it came with the harness looked solid. I do wish the horn trigger wires were a bit longer for my setup but I made it work. Overall I would buy it again
Review: Very nice harness - Works like a charm, easy to install. horn power and ground leads are very short, so the relay must be mounted within a few inches of the horn. For me that means above the radiator where it will be exposed to rain and dust. Time will tell how well it holds up, but for now it's certainly worth the $10 I paid for it.
