Maybe I'm blind? But I can't find a reference to the horn installation in the build manual for the MkIV?

Where have you guys mounted them on your cars? I am aware that it has to be pretty much in the vicinity of the wires on the front harness, but how have you found it best to mount? The hardware included doesn't seem particularly substantial...also there are two horns included in the complete kit, but there is only a single set of wires in the front loom.....how have you guys wired them in? I have seen pictures of Edward B's mounted horns in his build thread, but it doesn't show the mount nor the wiring..

Any helpful hints appreciated......p.s. I hate wiring, it is all voodoo black magic to me, and so I am finding this stage of the build particularly dull.
