If you already installed the 4-Way Curt Wiring Harness # C56225 on your 2011 Nissan Xterra, you will only need the Replacement Wiring Harness # 118267. You will not need the full 7-Way T-One Vehicle Wiring Harness # 118266 as you already have the relays needed from the 4-way harness.

You will need a Mounting Bracket # PK12711U for the 7-way connector.
