    He all, I recently got the prius c 2016, loving it, but I'm ready to add some things to it. I also like to use as much of the existing wiring as I can. I'm currently looking to add a secondary horn that requires about 20A. Looking through the fuse box in the cabin, I noted that there is a 25A fuse for the moon roof. However, my model doesn't have a moon roof, so essentially this circuit is free and I would like to use it. My only problem is I don't know which wire (or pin) coming from the fuse box will link me to it (or even if there is something else on said circuit).

    I've done quiet a bit of digging but i have yet to find a detailed wiring schematic for this car, any help?

    Worst case, is there an easy way to find the pin? I assume I could use a continuity tester to find it, but I'd rather get the info from the schematic.

    cheers!

    If you use the sunroof wire, it won't work with the ignition off, so no horn honking when the alarm/panic goes off. Just a thought.

    I bet a horn that pulls 20a is going to be impressively loud though!

    I'm well aware of that. in fact, due to it's loudness, I'm actually having a separate button to operate and preserving the original horn and it's wiring. The main reason i'm wiring into the moon roof circuit is simply so that it's a cleaner instaallation, just a preference really.
