I have a pool and spa light thats were just replaced with the Intellibrite 5g color LED lights. I'm adding an Intellibrite controller and have a question about the wiring. Coming out of the conduit for each light is white, black and green. However, there is also a yellow coming out of one of the conduits. What is the yellow wire for? Picture attached.
The controller has red, white and black. What is the proper way to wire this up?
