Installing FIAMM Horns on a '76 Wing

Postby landisr » Tue Apr 05, 2011 9:21 pm



I have a stock horn (only one) at the moment, but I also have a new set of FIAMM electric horns burning a hole on my workbench. I vaguely recall when I put some on a CB750 that I had to get 'creative' with the wiring because that bike had the horn button complete the 'ground side' to the horns. No? And aren't the horns set up for switchable positive ie getting ground from the mounting bracket?

So can anybody advise me as to the simplest way to hook them up?

Many TIA... again... Ron in MI

I found that the Honda horn button and the OEM wiring is pretty measly in terms of current capability. I put a set of FIAMM Freeway Blasters on my bike, and the bike couldn't supply enough current to sound them.

The simplest (and safest) way to do it is to replace your existing horn with the coil of a 15 amp automotive relay, and use the contacts of that relay to switch a fused line directly from the battery to the horns. Lots of current, which means LOUD horns.

Thank, WA. Upon reading this, it seems you have spelled out what it was that I did. So you're saying that the horn button 'ground circuit' is redeployed to 'ground' the relay, correct? If so, then I just scared myself, thinking that I understand something electrical... :mrgreen:

That's it precisely.

WingAdmins advise is great, I would suggest the same thing. We fitted some Fiam air horns to my friends bike and the first time he hit the button in anger, it blew the main fuse!! No horn and the bike stopped!! Using WingAdmins advise you would run a separate fused supply from the battery to the relay and onto the horns!! That is a much better approach than trying to use the original Honda wiring which is just not up to the current needs of air horns..
