Does this relay work with the hella horns or is this the same relay that comes with the hella horn?

This relay does NOT work with Hella horns, I tried to use it to install them on my Subaru and they did not function at all. go with this. https://www.rallysportdirect.com/fits/2010-subaru-impreza-wrx-sti-special-edition-hatchback-2-5/horns/grm-040005-grimmspeed-wiring-harness-for-hella-horns?gclid=CN-Y9t6tss4CFcZahgodee8AYQ

: Does the relay delay the new horns and just play the OEM horn if you just hit the horn button?

Are you leaving the OEM in as well? I replaced the OEM one with the dual blast ones and they worked fine with no delay

at the time i ordered this i did not know it did not come with a relay harness... does anyone know a harness i can get that is compatible? /w 2 relay?

iJDMTOY (1 12V Horn Wiring Harness Relay Kit Compatible with Car Truck Grille Mount Blast Tone Horns - COMES WITH A RELAY. This one fits all Subaru models. But harnesses without relay should work as well. I bought it with a relay for better performance and to protect the Hella horns. PS. Water and humidity will rust the relay connectors. I strongly recommend to apply a small amount of dielectric grease on all connector pins before installing.
