Cadillac 4 note horn install and wiring overview

A set of these horns can be had on ebay for 40-80 dollars depending on the condition. Be sure to get a set of all older style Delco Remy horns. They're much better than the newer style. The set is an A, C, D, and F note. A newer style C note was never made, and the rest are cheap junk, so get an older style set. Well worth it. They're louder than stock and sound great. Just a little mechanical inclination and basic understanding of wiring and your set to do this. Here's a good video on how to service them.    • How to fix a car horn   And questions? Ask away...
