Installing new horns (electrical question)

[LoJac963]

If I remember correctly not all the horn notes will be very loud, it's the combination of the 4 horns which give the distinct tone.

I wired all my horns off the stock horn wiring. Each side has 2 horns on the stock wiring. Now I don't know if the stock horn wiring is actually independent and wired separately of if one side is just pigtailed off the other, as in the passenger side branches off the driver side wiring.

Either way I wanted them to function as stock which is why I went with the stock wiring and not a second switch.

My goal is to have a Carson electric stutter horn on a separate switch for when I really want to get someone moving.
