First - I made a mistake in the name. Its not HEBEL but Stebel (close... ) I'll try to get some pics up but it's crowded in the engine compartment. All I did was to find a decent location for the two horms and mount on the supplied brackets good and tight. Then, just un-hooked the wire going to the regular horn and routed to the new ones. Simple. No worry on current/amp draws either from the ratings. The sound - MUCH better than the stock horn (at least i think so). Although, having a truck or train sound would be awesome - but no real place to mount trumpet horns, air tank, compressor, etc. Sound samples can be heard on the STEBEL web site listed earlier. It's sound is more of a large car from the 50's-60's. Hope this helps - and I'll see about pics and re-post. L8R
