Nissan Pathfinder (2022–Present) Flat-4 Wiring Installation
Vehicle Coverage: 2022–Present Nissan Pathfinder; exact trim and tow-package fitment are verified before scheduling
Output: 4-way flat trailer-light connector
Connection Method: Vehicle-specific plug-in connections; no factory lamp wires cut
Finished Connector Location: Mounted outside the vehicle near the receiver after connecting to the factory rear tow socket.
Installation Time: Typically 1–1.5 hours
Connector Location: Mounted outside the vehicle near the receiver after connecting to the factory rear tow socket.
The current Pathfinder uses Nissan’s prepared tow-wiring system. An interior relay harness activates the circuit and a second plug-in lead connects at the exterior factory socket behind the rear bumper.
1. Opening the Rear Cargo Wiring Area
The rear seats are folded and the cargo floor, threshold trim, cargo bin, tie-down, and required driver-side trim fasteners are removed without forcing the panels.
2. Installing the Interior Relay and Jumper Harness
The vehicle-specific relay assembly is seated in Nissan’s factory cargo-area connector and secured so it cannot vibrate against the trim.
3. Accessing the Exterior Tow Socket
The protected connector behind the rear bumper is uncovered and inspected for dirt or moisture before the exterior flat-4 lead is installed.
4. Routing the Flat-4 to the Receiver
The connector is carried to the hitch, supported away from the exhaust and spare tire, and mounted where it remains accessible but protected.
5. Testing and Reassembling the Vehicle
Running lights, brake lights, left turn, right turn, and ground are verified before the cargo floor, bin, trim, and battery connection are restored.
Why Location Matters: The connector is finished where the vehicle-specific harness is designed to keep it protected, accessible, and clear of exhaust heat or moving components.
