7-Way Wiring Harness For 2013 Nissan Xterra
Updated 02/16/2026 | Published 02/09/2026 >
Question:
Hello, Im looking to change over our 2013 Xterra from a flat-four to 7-pin to hook up to our tent trailer. After looking at the install video and literature, I checked out our truck to be sure it was matching what I saw in the videos. It already has a set of relays in the kick panel that look exactly like the relays in this kit. If we have the relays already, is it possible to order only the pig-tail and connector?

Hey Josh, thanks for reaching out. The Curt T-Connector Vehicle Wiring Harness # C56226 is what you will need to add a 7-way to your 2013 Nissan Xterra. It isn't available without the relays though, so you will end up with a few extras. Might not be a bad idea to swap out the old ones for the new ones, just to make sure everything works as it should.

Easy install. We drilled a hole in the steel fender by the license plate. The OEM mount is in a vulnerable location if you drive off road through gullies and dips. This was our second replacement for the OEM location, never again.
