Tekonsha 118267 7-Way Harness for Nissan 05-12
Tekonsha 118267 7-Way Harness for Nissan 05-12 — Product description
The Tekonsha 118267 is a 7-way replacement wiring harness for select 2005-2012 Nissan trucks and SUVs. If your factory tow-package harness has failed, corroded, or gone missing on a used truck, this plug-in unit gets your trailer lights, brakes, and power working again without splicing into the vehicle wiring.
Towing a boat trailer, a utility trailer, or a camper behind your Nissan? You need a clean electrical connection between the truck and the trailer, and that's exactly what the Tekonsha 118267 handles. It's a 7-way replacement for the OEM wiring harness on select 2005-2012 Nissan vehicles. When the factory harness fails, corrodes, or comes up missing on a used truck, this is the part that gets you wired back up.
A 7-way connector carries more than just running lights. You get turn signals, brake lights, tail lights, reverse, a 12-volt auxiliary line, and the dedicated circuit for electric trailer brakes. That last one matters. If you're pulling a heavier boat or a tandem-axle trailer with brakes, the 7-way is what lets your brake controller talk to the trailer. A 4-flat won't do that.
For boaters especially, trailer wiring takes a beating. Backing down a wet ramp, dunking the trailer, salt and grime, it all works against the connections over time. A failed 7-way is one of the most common reasons trailer lights quit at the worst possible moment. Replacing the harness with the correct OEM-fit part restores a proper ground and full circuit rather than patching in another questionable splice.
This is a plug-in style replacement, so it mates with your Nissan's existing tow-package wiring rather than asking you to cut and splice into the harness. That keeps the job clean and keeps the factory connections intact. Most folks can handle the swap in the driveway with basic hand tools. If you're not sure your truck came with the factory tow prep, check for the existing connector before you order.
Fitment is specific to select 2005-2012 Nissan models, so match the part number 118267 against your OEM harness before installing. Tekonsha has been building trailer wiring and brake controls for a long time, and this harness carries that same focus on a solid, weather-ready connection. Get it wired right and you won't be chasing flickering trailer lights halfway to the ramp.

Frequently asked questions
What vehicles does the Tekonsha 118267 fit?
It's a replacement 7-way harness for select 2005-2012 Nissan vehicles that came with a factory tow package. Match part number 118267 against your OEM harness to confirm the fit before you install it.
Does this include the trailer brake circuit?
Yes. A 7-way connector carries the dedicated pin for electric trailer brakes, along with turn signals, brake and tail lights, reverse, and a 12-volt auxiliary line. That's what lets a brake controller reach the trailer.
Do I have to cut or splice into my Nissan's wiring?
No. This is a plug-in replacement designed to connect to your Nissan's existing tow-package wiring, so you keep the factory connections intact instead of splicing into the harness.
Are all 7-way plugs wired the same?
The standard 7-way blade layout is consistent, but the harness that feeds it is vehicle-specific. This one is built to match the OEM connector on select 2005-2012 Nissan models, which is why fitment matters.
Can I convert a 4-pin trailer setup to 7-pin with this part?
This is a direct OEM harness replacement, not a 4-to-7 adapter. It's for restoring the factory 7-way circuit on a compatible Nissan. If you're adding trailer brakes or need more circuits, plan the wiring around a true 7-way setup.
Why did my original 7-way stop working?
On trucks that tow near the water, corrosion and repeated wet ramp launches are common culprits. A worn or corroded harness loses its ground and circuits drop out. Replacing it with the correct OEM-fit part restores the full connection.
