Electric trailer brakes are the magnet-and-drum setup on most travel trailers and fifth wheels, and the controller is what feeds those magnets the right amount of current. That makes wire gauge, circuit protection and axle ratings matter more here than a pretty display.

This list leads with four controllers, three proportional and one time-delay, then closes with two Ford harnesses that carry the controller's power to the dash. Order follows how clearly each listing states its braking type, axle range and protection features, with Tekonsha copy listings flagged as clones.

RV Gear Lab field notes

The Rig Fit Check

Start with the job: Lrichy 90885 Proportional Trailer Brake Controller Kit for 1-4 Axles leads this shortlist for Tandem and triple-axle trailers. Use that fit as a reference point, then compare the alternatives against your own space and workload.
Specs that separate the picks: The first details to compare are Replaces Tekonsha 90885, Replacement for Tekonsha 90160, Proportional, motion sensors. Confirm the exact model and included components before ordering.
Trade-off to plan for: Third-party clone, not made by Tekonsha

Before you buy

What Matters Before You Choose an Electric Trailer Brake Controller

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

01
Brakes per axle load
Electric trailer brakes use two electromagnets per axle, so a tandem trailer has four brakes and a triple has six. Every extra magnet draws more current from the controller, and a unit rated below your brake count can overheat. Match the listed brake range, such as 2-8 brakes, to your own trailer's axles.
02
Proportional versus timed
Proportional units follow how hard the tow vehicle decelerates, while time-delay units ramp on a preset schedule. The difference shows up as a smoother stop on a heavy trailer versus a firmer, simpler response on a light one. Look for the exact word proportional or time-delay in the listing title.
03
Circuit protection stated
Electric brake circuits can short out when a wire chafes or a connector gets wet. A controller with stated overcurrent or short-circuit protection can cut output instead of cooking a wire. Check the bullets for those words, and never assume protection exists if the listing is silent.
04
Wire gauge to the dash
The wire between battery, controller and brake plug carries several amps, and thin wire drops voltage. A harness that states 12-gauge copper wire is a stronger sign than one that only says copper. Look for a gauge number on any harness before buying.
05
Leveling requirement
Some proportional controllers must be mounted level, and others say no leveling is required or that they self-level. If mounting is awkward under your dash, this can decide fit. Find those words in the listing before drilling anything.
06
Replacement versus original
A listing that says replacement for Tekonsha 90885 or 90160 is made by another company. Warranty and support then come from that seller, not the original brand. Read the title for replacement or compatible with, and note the support terms.

The 6 best electric trailer brake controller, explained

Best Overall · 1 of 6

Lrichy 90885 Proportional Trailer Brake Controller Kit for 1-4 Axles

Replaces Tekonsha 90885
1-4 axles, 2-8 brakes
Voltage readout, boost

Check price on Amazon

Best for: Tandem and triple-axle trailers

Our take

Best for a tandem or triple-axle electric-brake trailer where a diagnostics screen showing voltage to the trailer is worth paying for.

Why it made the shortlist

The Lrichy 90885 is sold as a replacement for the Tekonsha 90885 Prodigy P2, so it is a third-party design, not a Tekonsha product. The listing describes proportional braking, support for 2, 4, 6 or 8 brakes across 1-4 axles, a bright LED display with voltage readout, and a manual override with multi-level boost.

Compared with the HRepair below it, it reaches a fourth axle and the mounting can rotate 360 degrees vertically with no leveling after mounting. The price is higher than the budget controllers lower down.

What works

Covers 1-4 axles and up to eight brakes
LED display shows voltage sent to trailer
Mounts without leveling after installation
Manual override plus multi-level boost

Watch out for

Third-party clone, not made by Tekonsha

Check price on Amazon

Best Self-Leveling Pick · 2 of 6

Replacement for Tekonsha 90160 Trailer Brake Controller 1-3 Axle Trailers

Replacement for Tekonsha 90160
Self-leveling, 3 boosts
1-3 axle trailers

Check price on Amazon

Best for: Single and tandem axle trailers

Our take

Best for a one to three axle trailer where you want a familiar proportional layout with plug-and-play wiring.

Why it made the shortlist

The HRepair is a replacement-style copy of the Tekonsha 90160 for 1-3 axle trailers. The listing describes proportional braking, a digital display with continuous diagnostics, three boost settings, and self-leveling technology.

Against the briidea below, it adds a snap-in clip or bracket with a 180 degree mounting range.

It is another third-party design, so support comes from the seller.

What works

Self-leveling design simplifies mounting
Three boost settings tune response to load
Snap-in clip or screw bracket included
Clear display shows brake and connection status

Watch out for

Limited to 1-3 axles
Third-party copy, not a Tekonsha unit

Check price on Amazon

Best Protection Features · 3 of 6

briidea Proportional Trailer Brake Controller

Proportional, motion sensors
Overcurrent and short protection
1-4 axles, 2-8 brakes

Check price on Amazon

Best for: Protection-minded first buyers

Our take

Best for a first-time electric-brake owner who values built-in protection against a wiring fault.

Why it made the shortlist

The briidea proportional controller is built around motion sensors and is rated for 1 to 4 braked axles (2-8 brakes). The listing highlights overcurrent protection, short-circuit protection and fault detection.

What works

Overcurrent and short-circuit protection are stated
Rated for up to four axles
Bracket allows any mounting angle
Fault detection flags wiring problems

Watch out for

Vehicle compatibility wording is very general
Less diagnostic detail than pricier picks

Check price on Amazon

Best Budget Controller · 4 of 6

8507111 Time-Delay Trailer Brake Controller Digital Electric LED Display

Time-delay braking
LED display, manual override
1-4 axles, 2-8 brakes

Check price on Amazon

Best for: Light, occasional towing

Our take

Best for light, occasional towing where simple and cheap matter most.

Why it made the shortlist

The Bydorunce 8507111 style unit is a time-delay controller, so it ramps braking up gradually after you press the pedal. The listing names an LED display, adjustable output, a manual override lever and 1-4 axle support (2-8 brakes).

It is a poor fit for a heavy trailer on mountain grades.

What works

Adjustable braking output for different loads
Manual override lever for emergencies
Compact under-dash body

Watch out for

Time-delay braking is less smooth than proportional
Wiring harness is not included

Check price on Amazon

Best Ford Harness · 5 of 6

CURT 51436 Quick Plug Electric Trailer Brake Controller Wiring Harness

12-gauge wiring
Quick plug, no splicing
Slit-loom sleeve included

Check price on Amazon

Best for: Ford plug-in installs

Our take

Best for a Ford owner whose truck year is on the listing and who is using a CURT quick-plug controller.

Why it made the shortlist

The CURT 51436 is a vehicle-specific plug-in harness, not a controller. The listing says it is built with 12-gauge wire to keep power steady between controller, vehicle and electric brakes, and it fits select Ford F-150 through F-550, Expedition, Lincoln models and others by year.

Compared with the Oyviny Ford harness below it, it adds a slit-loom sleeve for wire protection and states compatibility with CURT proportional, inertia and time-delay controllers using a quick plug.

What works

No cutting or splicing required
12-gauge wire carries power to trailer brakes
Slit loom protects the wiring
Works with proportional and time-delay controllers

Watch out for

Accessory only, not a controller
Fits only select Ford and Lincoln model years

Check price on Amazon

Best Value Harness · 6 of 6

Oyviny 3035-P Brake Controller Wiring Adapter Compatible with 1994-2008 Ford F-150 F-250 F-350 F-450/1992-2009

Ford 1994-2008 adapter
31-inch 4-pin harness
Plug and play, no splicing

Check price on Amazon

Best for: Older Ford trucks

Our take

Best for older Ford owners who match the exact year range.

Why it made the shortlist

The Oyviny 3035-P is a 2-plug brake controller wiring adapter for 1994-2008 Ford F-150 to F-450 and E-series among other years named in the listing. It is an accessory, not a controller.

It is 31 inches long, uses a standard 4-pin connector and uses ABS plastic and tin-plated copper terminals, and it costs a bit more than the CURT Ford harness in some listings.

What works

No cutting or splicing required
Standard 4-pin plug fits many controllers
Names older Ford F-series and E-series years
Nylon-covered wire protects the run

Watch out for

Accessory only, not a controller
Wire gauge is not stated on the listing

The catch: The CURT lists heavier gauge detail where this one does not.

Methodology

How We Built This Shortlist

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

Electrical protection

We compared which listings state overcurrent, short-circuit or fault detection, since electric brakes pull real current.

Braking style

We read each title and bullet for proportional or time-delay wording rather than inferring it from price.

Axle range

We compared stated axle and brake ranges against common one, two and three axle RV trailers.

Wire and plug detail

We compared harness listings for wire gauge, plug style and the vehicle years they name.

Clone labeling

We marked every listing that says it replaces a Tekonsha part as a third-party design.

Decision guide

Match an Electric Trailer Brake Controller to Your RV

By Axle Count

Your situation	Recommended pick	Why
Triple-axle or up to eight brakes	Lrichy 90885	Rated for 1-4 axles with a voltage readout for diagnosing the circuit.
Tandem trailer, three axles at most	HRepair 90160	Proportional with self-leveling, rated for 1-3 axles.
Single or tandem, want built-in fault protection	briidea Proportional	States overcurrent and short-circuit protection up to four axles.
Single-axle light trailer, tight budget	Bydorunce Time-Delay	Cheapest controller, covers 1-4 axles with a simple ramp.

By Budget

Budget	Recommended pick
$10 to $20	CURT Ford Harness or Oyviny Ford Harness
$20 to $50	Bydorunce Time-Delay or briidea Proportional
$70 to $100	HRepair 90160 or Lrichy 90885

Proportional vs Time-Delay Output

Proportional

Brakes follow your tow vehicle's deceleration, which means a gentle stop feels gentle and a hard stop feels hard. Lrichy 90885, HRepair 90160 and briidea Proportional work this way.

Time-Delay

Braking ramps up over a set time after you press the pedal, whatever the stop. Bydorunce Time-Delay is the only one here and suits light, occasional loads.

Default to Lrichy 90885 for tandem and larger trailers, and use Bydorunce Time-Delay only for light, rare towing.

By Install Situation

Recommended pick	Recommended pick
Ford truck with a quick-plug controller	CURT Ford Harness
Older Ford F-150 through F-450 or E-series	Oyviny Ford Harness
Mounting spot is awkward and angled	briidea Proportional
Mounting needs to be level-free and rotating	Lrichy 90885

For Wiring-Fault Worries Specifically

Look for

Stated overcurrent or short-circuit protection, as on briidea Proportional, and a display that shows trailer-bound voltage, as on Lrichy 90885.

In this comparison

briidea Proportional names overcurrent, short-circuit and fault detection, while Lrichy 90885 shows voltage delivered to the trailer so a weak circuit is visible.

When to Spend More

Spend more if

Spend more on Lrichy 90885 if you run a tandem or triple-axle trailer and want the voltage readout and four-axle rating that HRepair 90160 lacks.

Save if

Save with Bydorunce Time-Delay for a light utility trailer, or HRepair 90160 for a tandem where three axles are enough and self-leveling helps.

FAQ

Before You Bring One Home

Which electric trailer brake controllers work with my trailer?

Any controller works only if its axle or brake range covers your trailer. Count axles, multiply by two for brakes, and compare with listings like the 2-8 brake range on briidea Proportional.

What is a common electric-brake setup mistake?

Setting gain too high so the wheels lock, or too low so the trailer pushes the truck. Adjust on a dry, level road and re-check after the first few trips.

Is an expensive electric brake controller worth it?

If you tow a heavy tandem often, the extra diagnostics and axle range on Lrichy 90885 are useful. For a light utility trailer, Bydorunce Time-Delay may be enough.

How do I install one?

Mount it under the dash within reach, plug in a matching harness, and connect to the trailer plug. A listing like CURT Ford Harness avoids splicing if your truck year is covered.

Will these work with electric-over-hydraulic brakes?

Do not assume. Lrichy 90885 uses that wording in its listing, but confirm with the maker before using any controller with a hydraulic actuator.
