My LED button on my Antec DF600 FLUX

[GOATY7]

I have just built my pc in my DF600 FLUX case which has an LED button just above the power button. Im also using an ASUS ROG Strix B450-F Gaming Motherboard which doesnt have any argb headers.

My issue is that because of the lack of argb headers my last resort until I find a solution is to use my LED button to change colours but I have no idea where to plug the 2 pin wire (looks like all the other io wires) labeled as RGB is meant to go.

Also if possible pleasefind me a solution to the problem with mobo not having 3pin 5v argb headers. I have searched everywhere and couldnt find a solution so any help is appreciated.

 

thanks in advance
