    Just use the same wire for the stock horns. That's what I did. I have had no problems.

    Don't know what hella horns are but if there air horns you will need a relay as they pull alot of power for the compressor. Power the relay off the existing horn lead but then bring a #12 wire out of the fuse box to power the horn. You can bolt it under the front jump point but put a inline fuse on that wire though.

    I have one on my G2 they work good. And are really really loud.

    These are hella horns. MUCH louder than the stock horns.
    I just made a short 4 inch adapter cable because the stock wires didn't fit and
    I didn't feel to fighting with them. It was easy...

    I think that was from there web site. Or maybe as I searched I found it.
    But it is nice, and simple. I didn't do the relay though. It's been about a year, and
    The wired haven't melted... :)

    I use my horn, a LOT!

    It would depend on if you want the horns to operate when the car is off, or only when it's on.
    I think only while the car is on would be best...
