Hi everybody, just got a birthday gift,Fiamm Air Horns, Moss Motors part #545-080. The instructions seem pretty simple, if you are an electrician, which I'm not. Question #1. I have a 73B, do I have a horn button connected to positive or is it grounded? Question #2. Relay connection #30 shows a 20A fuse with an arrow. I don't think there is any 20a fuses in the B. Does this mean I have to run an in line 20A fuse? to where? Question #3. Should I locate the horns where the originals are or place them together, as it suggests air hose should be as short as possible? Question #4. Has anyone done this? If so, could you give me detailed instructions for a novice electrician? Thanks.
