240 Aftermarket Horns: Living my cycling team car dream

Hey TB,

I?ve got a 240 project car that?s beginning to take shape, and I?m getting into the fun parts. Part of that is installing this obnoxious horn that?s typically used in cycling team cars.

I haven?t found any english instructions for this. Anyone else installed a ?fun? horn in their 240? Any tips/tricks/traps I should be aware of?

Looking forward to my next inspection,
Greg
 
Those are a cool sounding horn if I am thinking of the ones I hear from the tour de france races. When you install the horn you'll want to use a 40 amp relay wired in. You can trigger the relay with the existing horn wiring so then you just have to wire from the junction block on the inner fender to the relay 30 and wire from the terminal 87 to the horns. Then provide ground for the horns. The trigger terminals are 85 and 86 on the relay. It's a standard 40 amp four pin relay.

That?s the one! I suspect it will be appreciated by my close friends and frowned upon by NY inspectors.

This is a huge help. Thank you. Will grab a 40 amp relay and have at it once the horn shows up. Looks like a pretty easy install and I?ll have plenty of room under the hood for it. Will try and grab a pic and a clip once it?s done.

I used one in a 145, and installed an extra rocker switch in the interior used for switching back and forth between the stock horn and the fun horn. State Inspection-friendly setup.
 
If you go to the horn link you posted, click on the word "Attachments" (light gray), and look at the bottom 2014-09-12_FIAMM_tourhorn_instructions.pdf file, it has brief instructions.

The original Volvo horn button grounds one side of the horn pins directly, so you want the Trio MT3i B wiring for "grounded horn button".

Got it! Yes. Between this diagram and the one that Dave Barton shared I think I?m dialed.

Off to find a rocker switch, some relays, connectors, and a wire loom.
 
Will they actually fail a car because the horn sounds different?

They really shouldn?t. I made that comment mostly in jest.

Language around horns in the inspection manual is brief and just calls out that it has to function. I?m sure an inspector who?s having a bad day could try and sell you a ?proper? horn but it seems unlikely.

Not really, but if you've effed with your horn, and other things, then maybe because you are a "risk," they'll spend extra attention on your emissions profile, the existence and operation of factory equipment, and anything else that could make you go away and find someone else to attest to your vehicle's safety condition.

You want to accommodate this, not fight it, unless you have the kind of money not to be installing a "cycling team car" horn on a decrepit Volvo...
