Helpful Expert Reply:

Since you already have a factory 4-way trailer connector on your 2009 Nissan Pathfinder use our # ETBC7 kit to convert it to a 7-way. It uses your existing 4-way and leaves you with a fully functioning 7-way with a 4-way as well. I've linked a video of the kit being installed on an Xterra for you. The vehicle is different but the process is basically the same.

Then to install the P3, part # 90195, there should be a connector under your Pathfinder's dashboard. Use part # 3050-P to connect the P3.
