Need help installing them. I got a pair of hi/low JDM tiiiite! Mitsuba Aerospiral II's for cheap but each horn requires 2 connectors and the stock lancer horns have 1 connector each. There are instructions on the box but the damn thing is in japanese

has anyone installed a similar setup?

 

I'd just splice wires together How many wires are there for the stock connector vs. wires for the aftermarkets?

 

Hmm.. I put a horn on my old talon because the stupid things would always get full of water. But, I think you should try to look at the directions again if there are pix and try to see if there is a ground cable or something. Maybe post pix of it too, or a website that has them. I had a ground wire and an ACC wire on mine. The ACC wire is what goes to the horn and makes it honk when you press the horn. But japan always confuses me.. my acc wire was green.. but on some things in japan the ground wire is green because they call it "earthing" instead of grounding.. lol.
