Dual horns

[grapejuice1998]

I was given a set of Bosch dual horns today. It came with a relay, but no wiring diagram. Since my factory horn quit, I already put one of them on. It works great, but it has me thinking about installing the second one. I don't think you can have too much horn on a bike in a city like Dallas.

My question is; wouldn't the bike's horn already be run through a relay? Would it be absolutely necessary to use this one to run the duals?

I have a wiring diagram for my '98 750ACE and it does not have a relay for the factory horn...... Can't speak for other models.

I used a relay when I installed my air horns. You probably should just bite the bullet and install the relay.
Good luck,

It's just a generic relay, so I'm sure I could get a wiring diagram online. I'll give it a shot.
