The spa light is not working and believe I need to replace. At this point, I've gotten it out of the spa, but can't get the whole cable to come out. While trying to figure that out, I want to disconnect it from the control panel to make sure no electricity is flowing through it. It's wired to AUX 5. Can I just unplug the red/black wire connector under the control panel (Photo #1 - yellow highlight)? Or do I need to disconnect something relays below the panel (Photo #1 - red highlight)?
