The corroded wires will need to be replaced with new wire and that will help with the running light problem. But there could be corrosion elsewhere so you will need to inspect the trailer wiring from front to back and repair as needed. Also, make sure the trailer side connector is clean and free of corrosion inside where the wires attach and outside on the pins.

To switch the ban over to a 7-Way you will need # ETBC7. This will provide the 7-Way and retain a functional 4-Way. It also provides the wiring and accessories needed to install a brake controller. I have included some links that show and explain the ETBC7 installation.

For a brake controller I recommend the P2, # 90885, because its easy to set up and use and its reliable.
