Your outside lights are working because they are attached to the running light circuit on the vehicle. It sounds to me as if the 12 volt circuit in your connector is not wired properly or is not present. I would check the connector on the vehicle with a circuit tester, item # 3808 if needed, for a constant 12 volt circuit. If you find a 12 volt circuit in the vehicle side connector then you will need to figure out which circuit on the trailer connector goes to the inside lighting. Once you find the proper wire on the trailer side you will need to attach it to the connection point in the trailer connector that corresponds to the 12 volt circuit on the vehicle side.
