Installed my quad hella horns last night after repainting them. They were the standard red before since my 16 impreza was red. Used the same harness and just cut the horn connection off and soldered it since I didn't have a spade connector to use to just plug in to the factory connector. Have tons of parts on the way and a few parts that came off the impreza to put on the outback, found out a Perrin front plate relocation mount will work on the outback. But it's extremely close to the front bumper and that's with it only hand tight.
Holy horns!! How did you wire these?! I would love to have these in all the Atlanta traffic I drive in..lol
