Synchro-rev not functioning/illuminating

preR35

Update: It's working currently, all it took was removing the shifter trim piece yet again and fiddling with the back of the button. Nothing really seemed loose though, and I didn't hear or feel anything snap into place.
Hopefully it's fixed for good and won't be an intermittent issue. At the moment, my only thought is that maybe I had bent a pin when I was first taking the center console apart during the radio install yesterday. I did initially try to unplug those connections (s-mode and hazards) from the shifter trim, but gave up and decided to work around them.
