How do I wire a 2nd horn?

[Dafey]

Do I go from : power on existing horn , new horn + , horn neg , ground?
I only have the low tone and I want to ad the hi tone also.

Bolt horn on truck run wire from other horn to it! How my GM setup is.

So like I said?
Some one was telling me it would cut the power in half or some crap..
I saw the front end off a truck and noticed it had 2 horns...So I figured why not...?

 

[Metrodps]

books only show one type fuse and horn relay and that is how mine is hooked from factory. I am sure if it is wrong some one will brow beat me for it....

Metro has it right. It will cut the voltage, but not nearly enough to affect anything. From the factory they are wired from the relay to one horn with a second wire running from the first horn + to the second horn +.

Wire in three different tone horns , then you could play a chord

You would parallel them, i.e. old + to new +, and both ground through their bolt. The only change in voltage / power delivered is loss through the wire, a la the headlight relay upgrade, which is minor at most.

Do scrub the area where the bolt goes so as to get a good connection, as you would for a battery cable to the body or frame.
