5 Best Trailer Brake Controller For Infiniti Qx80 in 2026: A Practical RV Guide
Brake controller kits and plug-in harnesses for the Infiniti QX80, with how to check the factory tow connector and the model years each listing names.
By Hardcastle's RV Editors
10 min read5 products evaluated
The Infiniti QX80 shares its tow-harness family with Nissan's Armada, and listings that cover it typically name the 2014 to 2021 model years. If your QX80 has a factory tow package, a connector under the dash accepts a plug-in harness, and a factory-integrated controller would make any aftermarket unit unnecessary.
The five picks are three Rizz-Man controller kits that include harnesses and two harness-only products. Start by confirming the port and your model year, then decide whether you want a controller bundled in or want to choose your own.

How We Built This Shortlist
Each pick was assessed across 5 criteria weighted for real-world use.
- QX80 year match
- We compared which listings name the QX80 and its 2014 to 2021 span, rather than relying on general Infiniti wording.
- Bundle versus parts
- We separated controller kits that include a harness from harness-only parts, since the latter need a controller bought elsewhere.
- Activation type disclosure
- We noted which listings state proportional or timed behavior and which leave it out.
- Axle support
- We compared stated axle ranges, because a heavy trailer needs a controller rated for its brake count.
- Connector certainty
- We checked which listings tell you to verify the connector, as an honest note about limits.
What Matters Before You Choose a Trailer Brake Controller For Infiniti Qx80
Key buying criteria so you get the right fit the first time.
Factory tow connector
A QX80 with a factory tow package typically has a brake controller connector under the dash that accepts a harness. Without it, you would need a different install. Look under the driver-side dash for an empty connector before you order anything.
QX80 model-year range
The listings here name QX80 for 2014 to 2021, so a newer truck sits outside what they claim. A harness for the wrong generation will not plug in. Compare your model year to the listing and avoid guessing.
Controller activation type
Proportional controllers follow the vehicle's deceleration, and timed ones ramp over a fixed interval. For a heavy trailer behind a large SUV, proportional is smoother. Only Rizz-Man 8508211 states proportional on its listing, and Rizz-Man 8507111 states timed.
Axle count rating
Each trailer axle adds two brake magnets that draw current, and a controller has a maximum. The Rizz-Man 8508211 and 90195 list 1 to 4 axles, which covers most travel trailers. Confirm the number on the listing rather than assuming.
Harness quality
A harness runs behind the dash, where heat and vibration can wear cheap insulation. Braided mesh and copper conductors help. Tekonsha 305000 names braided copper wires, while Shulgf TPH-014 names copper core and insulated outer material.

For Towing a Large Travel Trailer Specifically

- In this comparison
- Rizz-Man 8508211 lists proportional braking and 1 to 4 axles, so it covers a tandem-axle trailer behind a QX80 best.
When to Spend More
- Spend more if
- Spend more on Rizz-Man 8508211 or Rizz-Man 90195 if you tow a tandem-axle trailer and want controller and harness matched in one order.
- Save if
- Save with Shulgf TPH-014 if you already own a controller, or choose Rizz-Man 8507111 for a light trailer.
Before You Bring One Home
How can I tell if my QX80 has a tow connector under the dash?
Look for an unused connector near the driver-side lower dash and check whether the SUV has a tow package. A factory-integrated controller would mean you need no aftermarket unit.
What mistake do QX80 buyers make?
Skipping the model year. The listings here name QX80 for 2014 to 2021, so a newer vehicle needs its own confirmation. Also check that a harness matches your controller's plug.
Is the proportional Rizz-Man worth it over the timed one?
For heavier trailers, yes: proportional braking follows the vehicle's deceleration and feels smoother. A timed unit like Rizz-Man 8507111 suits light, occasional towing.
How do I set the controller up?
Plug in the harness, mount the controller, hook up the trailer, and set gain on a dry, level road. Raise it until the trailer stops firmly without locking the wheels.
Does a QX80 need anything else for towing?
It needs a working 7-way trailer socket with a powered brake output. Test it with the trailer attached before you leave.
