PSW111 subwoofer LFE connector Red or White?

Hello
Just bought the PSW111 subwoofer. The manual is not clear which connector is for LFE connection to my Denon AVR. Is it the - Red or White connector- using single RCa cable to sub out on my AVR?

Also I have the sub on Auto but the light never turns off, shouldn’t the light be off when the AVR is off?
Thanks you for your help
