Well i have finally got around to fitting the stebel horns today ,using the loom supplied i sorted out where i was going to hang them ,the only problem was the loom was for one horn not two so some cutting and manufacturing was required for the off shoot thankfully i have a heap of gear so there was not problem , after a few disasters with my polarity i finally got it right at one point i hit the horn button and it stayed on the only way to stop them was to disconnect the battery ,the horn wasnt fully tightened down and it was flopping around like an untrained seal they are loud even one of them .Anyway they all work now so moblie phone users and sh#tty drivers beware .
