Hi there, after reading through the forums and not getting any answers I decided to post my horn problem. I bought my 1990 Daytona ES (3.0 L) with a few problems (lights didn't pop up, etc.) and managed to get them fixed myself, but this horn problem is the worst. I tested the old stock horns and noticed that they didn't work after putting them on the battery, so I bought some FIAMM trumpet horns (one high note, one low note), and they still did not work. I had to argue with many parts places for a horn relay and finally after getting the right relay (12 V 5 pin), I still have no power to the horns. I tested the connections with an ohm meter and I have continuity and now I am stumped. :bang head PLEASE HELP!!!!!
