2012 front diff

Hello,
I recently disassembled My front diff on my 2012 900 rzr
To replace a bearing and after putting it back together it seems to keep going to AWD even when the plug is unplugged , I’m having a hard time remembering how the black plastic ring goes back in , it had a metal ring that that goes in a grove on it and I’m not sure if the ring hooks the little pin or just goes up to it.
Sorry if this is a very good description but I’m trying my best.
Thanks
