Does the CMHSL need power for rearview camera to work?

[LBC_Jeff]

As the tile suggest, I’m curious if I need power to the CMHSL for the digital rearview camera to work.

I picked up a used CMHSL I wanted to just plug the camera in to see if it worked and it didn’t so I wasn’t sure if I needed to feed power to it to make it work or if I have another issue

Thanks
