I bought an RBG light off e-bay which has an IR (Infra red controller) in the board and only 2 wires coming out (12V Power + & -)

Now I would like to connect that light to an RGB controller which has 4 outputs (Power, Red, Green and Blue)

After Opening the light this is what I found:
* please know that the diagram is my best guess.

So my question is this:
Can I just simply disconnect the "Negative Wire" and add the 3 separate RGB's like so:

Or should I disconnect the circuit board as it won't be needed?

Example of what I want to do:

No, the rgb leds need a dc supply and a control voltage pin for each led, the controller you have is for Negative voltage control to each led with a positive common.
