Mine wasn't working at first. The light inside wasn't coming on either. I then went back to where all the plugs are at the passenger side. I didn't have the plugs going to the correct spots. That's the problem with all the connectors being the same, too easy to interchange and make wrong connections. I disconnected all of them and started over.
The one plug/connector combination is easy since they're reversed from the rest of them. The video says the other ones don't matter, but it does matter. I matched the wire colors on both the plug and connector and lo-n-behold it works now!!!
