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.

At a glance

Our top picks

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.

Before you buy

What Matters Before You Choose a Trailer Brake Controller For Infiniti Qx80

Key buying criteria so you get the right fit the first time.

  1. 01

    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.

  2. 02

    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.

  3. 03

    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.

  4. 04

    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.

  5. 05

    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.

Check price on Amazon for Rizz-Man 8508211 Proportional Brake Controller & Wiring Harness (opens in a new tab)
Best for: Heavier towing with a 2014 to 2021 QX80

Our take

Rizz-Man 8508211 Proportional Brake Controller & Wiring Harness makes the shortlist because listing calls it proportional braking.

Why it made the shortlist

The Rizz-Man 8508211 is sold as a proportional brake controller with a wiring harness, and its listing names Infiniti QX56 2004 to 2013, QX60 2013 to 2020 and QX80 2014 to 2021, plus Nissan Armada, Frontier, NV vans, Pathfinder and more. It lists brake control for 1 to 4 axes.

What works

  • Listing calls it proportional braking
  • Names QX80 for 2014 through 2021
  • Controller and harness come together
  • Covers 1 to 4 axle trailers

Watch out for

  • Listing stops at 2021 for the QX80
The catch
The Rizz-Man 8507111 below is timed, and the Rizz-Man 90195 does not state a type.
02
RIZZ-Man 90195 Brake Controller with Wiring Harness
  • 90195 controller plus harness
  • QX80 2014 to 2021 listed
  • 1 to 4 axle control
Check price on Amazon for RIZZ-Man 90195 Brake Controller with Wiring Harness (opens in a new tab)
Best for: Owners who want the 90195 part number

Our take

A good choice if you specifically want the 90195 style of controller.

Why it made the shortlist

The Rizz-Man 90195 is a controller with wiring harness under the 90195 part number, and its fitment bullet names Infiniti QX56 2004 to 2013, QX60 2013 to 2020 and QX80 2014 to 2021, along with Nissan Armada and Frontier. It also lists 1 to 4 axle control.

What works

  • Names QX80 for 2014 through 2021
  • Controller and harness come together
  • Supports 1 to 4 axle trailers
  • Compact dash-hugging design

Watch out for

  • Controller type is not stated
03
Best for: Light trailers with a QX80

Our take

Best for a QX80 owner with a light trailer who wants a display and straightforward settings.

Why it made the shortlist

The Rizz-Man 8507111 is a timed electric brake controller with wiring, and its listing names the same QX56, QX60 and QX80 years as the other Rizz-Man kits. It has a real-time LED display for brake voltage, adjustable power and sync rate control.

It ranks third because the listing gives no axle count.

What works

  • LED display shows brake voltage in real time
  • Adjustable braking power and sync rate
  • Names QX80 for 2014 through 2021
  • Plug-and-play installation

Watch out for

  • Timed braking is less smooth than proportional
  • No axle count on the listing
04
Best for: Existing controller owners on a budget

Our take

A budget way to get the QX80 connector for an existing controller.

Why it made the shortlist

The Shulgf TPH-014 is a third-party harness that replaces the TPH-014 part, and its listing names Infiniti QX56, QX60 and QX80 along with Nissan Titan, Frontier, Pathfinder, NV vans and Xterra, plus Honda Pilot. It connects behind the dash without cutting.

What works

  • Names QX56, QX60 and QX80
  • Installs without cutting or splicing
  • Copper core with insulated outer layer
  • Also lists Nissan models for shared garages

Watch out for

  • No model-year range for the QX80
  • Third-party replacement, controller not included
The catch
Unlike the Rizz-Man kits it brings no controller, so it only suits owners who already have one.
05
TEKONSHA 305000 Trailer Brake Controller Custom Harness
  • QX80 2014 to 2021 listed
  • Four braided copper wires
  • Works with Tekonsha controllers
Check price on Amazon for TEKONSHA 305000 Trailer Brake Controller Custom Harness (opens in a new tab)
Best for: QX80 owners choosing a Tekonsha controller

Our take

Best for a QX80 owner who prefers to choose a Tekonsha controller separately.

Why it made the shortlist

The Tekonsha 305000 is a custom harness listing Infiniti QX56 2004 to 2013, QX60 2013 to 2020 and QX80 2014 to 2021, plus Nissan Armada, Frontier and NV vans, and it excludes the Titan XD. Four braided copper wires follow a factory-installed look.

It works with proportional or time-based Tekonsha controllers, and unlike the Shulgf TPH-014 it states the QX80 years.

What works

  • States QX80 years clearly on the listing
  • Works with proportional or time-based Tekonsha units
  • Braided mesh protects the wires
  • No cutting or splicing needed

Watch out for

  • Harness only, no controller included
  • Listing asks you to verify fitment first
The catch
It is the clearest harness here, yet it lacks the bundled controller that makes the Rizz-Man kits convenient.

Methodology

How We Built This Shortlist

Each pick was assessed across 5 criteria weighted for real-world use.

01

QX80 year match

We compared which listings name the QX80 and its 2014 to 2021 span, rather than relying on general Infiniti wording.

02

Bundle versus parts

We separated controller kits that include a harness from harness-only parts, since the latter need a controller bought elsewhere.

03

Activation type disclosure

We noted which listings state proportional or timed behavior and which leave it out.

04

Axle support

We compared stated axle ranges, because a heavy trailer needs a controller rated for its brake count.

05

Connector certainty

We checked which listings tell you to verify the connector, as an honest note about limits.

Save with Shulgf TPH-014 if you already own a controller, or choose Rizz-Man 8507111 for a light trailer.

FAQ

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.
