Depending on the pin that was pulled out of the connector on the truck it may have created a short (when it was pulled apart) which has blown 12 volt fuse(s) in the breaker box.  The things that you indicated that do not work all require 12 volt power, even the fridge (for controlling).  With a blown 12 volt fuse(s) that could cause these failures.  The only exception to this is that the lighting in the camper works, which you indicate works but requires 12 volt power. You need to first repair the connection on the truck, then start checking the 12 volt system including the fuses in the trailer.  It will take rudimentary electric knowledge along with some basic tools such as an electrical multimeter.  Hope this helps.
