This is posted on another site, but I thought I could get some more input here also. In the process of installing "Freeway Blasters" Fiamm horns in thew same area as the (only 1) stock horn. I have been told that a "relay" is needed for the dual horns, then was told one is not needed. I am confused. I know that area in front of radiator is tight, and I understand about maybe having to make a homemade "bracket" for mounting. No problem.
I am good with wire connections, using the heat shrink tubing, etc... . The plug that was on original was a green and brown. From some previous excellent help, I was told the brown is the ground. I am a little concerned about the relay part though, as I don't want to burn up my wiring. Any input/pics would be great. Thanks to all.
