@HFarr,
Unless RGB was a factory option on that year/model, then its unlikely the factory harness has a 4-con to each LED. If this was the case, then you would simply find the 4-con's termination point behind the helm, and remove the brue ground and attach the red ground and the color change is done. There would be no need to visit each LED's splice.
If I was going to do this, I would clip the factory 2-con off each LED and run my own 4-con to where I would mount the controller. This is much easier then trying to run a 2nd 2-con and then relocate the original factory 2-con to the controller location. The single color switch could then be used to power the controller on/off.
