how to connect outdoor led rgb to existing 12v cable

Hi all

In my backyard, I already installed a 300 watt transformer.  I connected/ran a 12v low voltage cable around my back yard.
It was for an uplight project.  Now, I removed all those lights (the 12v cable still there) and want to install LED RGP lighting.
Im stuck at how to connect the RGB controller to the existing  12v cable.

Any advice is greatly appreciated. 

Thanks a bunch,

Most RGpB controllers and uPs run on 12 VDC...
I do not see a problem ?

As i said in your other post we need to know what the power needs of the controller are.
