Quick follow up. Unfortunately, it's not the connection at the mirror so it's either a loose connection at the shark fin or the connection is corroded from moisture.

The video connector does not look like any that I found on the internet. The female end of the connector where the release is, clips into the mirror module and only fits upside-down, meaning the release is not accessible unless you remove the connector from the clip in the mirror module. The short length of cable feeding the connector barely has enough slack to allow the connector to be removed from the clip so it can be rotated 180* to release the male end. The red arrow is pointing to the black release tab, pinch it and pull on the male end. Pic to hopefully help someone else down the road.
