Andrew,
I'm running a little late on this one, but.....
Trevor Jordan was correct when he said to connect to a purple wire. The
purple wires are hot all the time, and they are fused. This means you don't
have to add a separate fuse for the radio if you don't want to (although
nearly all radios come with a fuse already installed in the line). Use
whichever purple wire is convenient.

The fix given to you by Trevor will work just fine, but that method leaves
the switchover relay energized whenever you have the FIAM horns selected, and
requires the use of a relatively hard to find and expensive SPDT relay.
Nothing at all wrong with that, but I just prefer not to have the relay
operated more than needed -- I would rather operate the relay only when it is
needed, ie only when the horns are actually blowing -- and I can't buy the
SPDT relays where I live, I have to mail order them.
As I said, there's ABSOLUTELY nothing wrong with Trevors suggestion, but I'd
like to offer an alternative. I think there might be a fair amount of
interest in this, so I made up a web page (dontcha just love the internet?)
with detailed instructions for doing this, including diagrams. It can be

If so, that's two of us, as I like to do stuff like this.
