Question:
For a 2019 Nissan Pathfinder wtihout the factory tow package, if already installed Curt C56281 from eTrailer, can I install Curt C56357 using the same internal/behind the panel wiring they look the same in your photos - so Id really just be adding the plug-and-play 7-pin harness, and then add Curt C64QV - for working trailer braking?

Hey Jordan, if you have the # C56281 currently you can pretty easily swap to a 7-way using the part # C56357 and you wouldn't have to install all of the kit as a lot of it duplicates what you have already. Realistically you would just be using the 7-way and the main harness that comes with it. Then you can use the wiring of the kit to install the brake controller # C64QV you mentioned as well. What are you towing?
