Easy to install once you understand the basics of installing on electrical equipment. Your diagram was wrong, but it's easy to figure out what's wrong. Loud enough but too high for me and the compressor barely has enough power to blow the BORH horns, usually only one really blows unless pressed for a good 3 seconds.
