My harness, 7 pin plug and class VI hitch were all factory installed. everything worked fine until i went to change out the corroded male connector to an identical replacement. So I would assume that the problem should be fixable without buying or changing anything as far as the connector. I did forget to disconnect the battery while doing the swap so my thinking is that i might have shorted out something in the circuit by accident. Question is what or where?
I should add that when my camper is hooked up everything works on it (running lights, backup lights, turn signals, power to trailer) with the exception of the brake lights. Camper plugged or unplugged the cherokee's brake lights still don't work.
