Question:

I have a Wells Cargo 24ft trailor with ceiling running lights inside lights dont turn on but the outside lights all around the trailor work. The dome lights have a switch on each light with a main switch on the wall tried every combination still no lights. Coming from the main switch directly to my car battery the dome lights work with switch lights on lights off flicking switch

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 # PTW2993 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.
