Need help with the Phanteks P300 case

[GensenPrime]

First time builder here. I just built my first pc in the Phanteks Eclipse P300 and it went very well. The P300 comes included with RGB lighhting for the side glass panel and the power button, but idk where to connect the RGB cable. I don't see anywhere on my motherboard where I can connect the cable. Idk if it has something to do with the motherboard not being compatible with the RGB features or if I'm just blind and cannot figure out where the connector plugs into. I've checked the Phanteks case manual and it doesn't say anything about connecting the RGB Led connector. Can anyone help?

This is my motherboard: https://www.amazon.com/GIGABYTE-GA-AB350M-Gaming-Ryzen-SMART-Motherboard/dp/B06XF49QNM/ref=sr_1_1?ie=UTF8&qid=1545349190&sr=8-1&keywords=gigabyte+ga-ab350m

Edit: Figured it out. I had to connect the LED connector to a SATA connection on the power supply.

I use a Phanteks Eclipse P400S case and I think the lighting cables for mine as the same as yours. If that is true, they do not plug into the motherboard at all and instead is just powered by the PC's powersupply. They wont sync up with your motherboard or GPU if they have their own RGB lighting but you can manually set them to match through software.
