If it is anything like my 08 1055 the wires don't directly lead to the battery comparment. one set ran from the roof to under the sink and the other from under the sink to the battery compartment for you could wire in the controller. And there should be a positive and a negative wire to connect to the battery from the controller. Find the wires connect to the roof panel then test with an amp meter to find the proper lead to hook to the controller. do the same with the wires going from the controller to the battery comparment then once you know which is which hook up the batteries
