    will be upgrading the horn and would like to run a relay as the horn I choose will draw more power than the stock system. Is there a clean way to tap into a 12 volt source under the hood? Tia.

    Idk about gen 5, but gen 3 you could unbolt the 12v at the jump point. Since they put the battery back in the hatch, it might be similar

    Good point, I think I noticed that when I removed the fuse box cover.

    Under the fuse cover, near the booster plate, there is a 10 mm nut on a lug that can take a ring terminal. It's a direct line from the battery.
