Last weekend I purchased a 2005 Maxima for my daughter. The next day she reported the lighter socket wasn't working to charge her phone. The fuse checked good. But when I removed the fuse box panel near the steering wheel I discovered a connector hanging loose. Is this a test lead or did it fall off? I can't see where it might connect.

So now a couple of days have gone by and more electrical gremlins have appeared. The tail lights are out, as is the pump for the wiper fluid and the light by the shifter. Is there a common problem for all of these, or did I purchase a nightmare?

Thanks in advance.
