Are There any Parts of Curt 7-Way Kit for 2020 Nissan Pathfinder that Don't Get Used  

Updated 01/19/2026 | Published 08/03/2024

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.

Hey Bett, how did things go with the Curt 7-way kit on your Pathfinder? Did replacing all the harnesses work out as expected? Your update could make it easier for others doing the same wiring change.
