Had to take off the grille, remove the factor horn, and make a bracket. Ran the factor horn wires as the relay power and ground, then ran poz and neg direct to second battery for horn power. Much louder directionally, however still sound European and kind of pitchy. She don't sound like a sixty two Cadillac, way better than the factory horn tho.... Now if I can hook up the freight train horn kit I will be golden.....

Hella Twin Supertone Horn Kit
I got the horns for Xmas to replace the wimpy single horn that came with my 2012 Sprinter Van. The instructions showed a very complicated wiring diagram that was not needed at all. I simply wired the two horns in parallel from the two wires that powered the OEM MB horn. They are much, much louder than the OEM horn and sound more European too!! The whole job took me less than two hours and I could do it now in only 45 minutes if I had to do it again.

Mounted easy enough but not at all what I
Expected sound wise. Not that loud
