You can also purchase this harness for the hella horn kit:

Used that when I had my STi. Still on the fence about picking up supertones, but yes, they need to be ran on their own relay to utilize their loudness.
You don't even really need to buy a harness, you just need the relay. one is power, one is ground, then the other two go to the horns. Super simple if you have the wiring.
I'm still on the fence on what to do with the water pump, if I want to just run it as is. (the harness tapping off the injector)
