Is Powered Converter Needed for Proper Operation of 4-Way Connector on 2013 Toyota Highlander  

On my 2013 Toyota Highlander, I just connected the 4-pin harness to the connection point at the rear of the vehicle, under the cargo bins. I bought the 4-pin to 7-pin conversion harness and installed that as well. I connected the ground wire to bottom frame as instructed in the instructional video, and connected the 4-pin connector to the receiving 4-pin piece on the 7-pin connector. I plugged my campers 7-pin connector into the receiving end on my hitch, and none of the trailer lights came on. I checked the wiring, connections, etc. and the trailer lights were working great when I had a guy off the camper for me the night before. I did just order the converter that connects under the front dash on the Highlander, because I dont think it came w/ the factory installed one. Without the converter, shouldnt the camper lights still turn on? Or, is the converter the solution to why theyre not turning on? I thought the converter was just to prevent overloading the vehicles lighting system, but Im wondering what else could be going on for the camper lights not to be on. Thanks.
