Second horn on a 2012 RT

I have read most of the posts on beefing up the wimpy stock horn so I have a pretty goood idea of the choices. I have decided to install the dual horn set up form the earlier RT's and have already ordered the parts from my dealer. But being the electrical idiot that I am, I have a few questions about the wiring and hope someone here can help me. I purchased the 2 pin repair plug and intended to splice that into the stock horn connector wire. But I can see that it is too short to reach from where the second horn will be mounted. Can I just add some wire to the repair plug and then splice into the stock horn harness using a posi-tap? any special issues re wire gauge or method of connecting the wire extensions to the repair plug? any polarity concerns? anyhting else to worry about??
In short, if someone who has already done this can give me detailed instructions I would be most appreciative.
Thanks in advance.

Somewhere about 2009 the wire harness for dual horns went away. There is a real posibility that if you do wire two larger horns to the original circuit the computer that monitors excessive power flow in this circuit will cut it off. You need to use the original horn circuit to power a relay that gets its power from the battery directly (fused) and then goes to your new dual horns via the relay. If you search this list you will find threads detailing how to do this using some factory connectors for the trigger circuit wiring and setting up a relay. You need to do some research on this or have someone do it for you. Maybe some local help to do it together? Not easy to find space for the horns and a solid bracket. There are loud horns out there, Check Aerostitch. I suggest this one because it is cheap, smaller than the air powered ones that are a bit louder, thus easier to mount. I'm still looking for space to mount a five trumpet unit that plays La Cucaracha (
Here is the link to a good horn.[/QUOTEInstalled the x-tra hornin my '09 and the wring and mount was already there. Bought the Bike late may of 2009.
