disclaimer: i am not 100% sure about this. since i have never done it before
the red and black are the ones you need. you could either splice and connect your wires with the oem ones, or you could buy this kawasaki oem adapter for $4.99

also, you could cut off your turn signal side connector and attach it to your new turn signal.
i don't know what the 3rd wire does, but you said it is the daytime running light? well, if you do attach the 3rd wire into the hot horn wire, then you can use one of these quick splice connectors.

i am not sure how much draw those lights have. i wonder if it would cut down the power available to your horn if you did use the running lights? you could also just attach it directly to your battery, huh?
just cover all your work with some electrical tape or something.
i have wired up stuff in my car, but i am new to motorcycling. just trying to throw out some ideas.
