Question:
2020 pathfinder factory prewired. Came wired to o 4 flat. Changing out to o 7 blade. Got curt harness to change. I think I only need to change the wiring to the plug in, not the wiring that was added inside the rear panel that sends juice to factory prewired plug in passenger side. Correct?

Hey Bett, the Curt 7-way kit part # C56357 that fits your 2020 Nissan Pathfinder does include a couple extra harnesses and several relays. You will need to replace all of the harnesses with what comes with this kit but there might be a couple extra relays when you are done.
