Can I add a tow hitch to my Toyota Highlander?

Yes. You can add a tow hitch to most Toyota Highlander models, using either a factory towing package or a reputable aftermarket hitch. The exact capacity and wiring requirements depend on the model year, engine option, and whether a towing package is installed.

This article explains the options, what to check before you buy, wiring and installation considerations, and how towing capacity can vary across generations of the Highlander. It also offers practical steps to ensure safe and compliant towing.

Hitch options for a Highlander

Below are the common routes people take when adding a tow hitch, along with what each option typically includes and what to watch out for.

• Factory towing package: Many Highlander trims offer an factory-installed towing package that includes a hitch receiver, dedicated wiring harness, and sometimes additional items like a brake controller or transmission cooler. This is often the simplest path to a reliable setup and ensures compatibility with the vehicle’s electrical system.


• Aftermarket hitch (Class III 2-inch receiver is standard): If your model didn’t come with the factory package, a reputable aftermarket hitch from brands such as CURT, Draw-Tite, or Reese is a common choice. Ensure the hitch is rated for the vehicle’s towing capacity and that the installation is performed correctly.


• Wiring harness options: For both factory and aftermarket routes, you will typically need a wiring harness for trailer lights. Common options include 4-pin, 7-pin, or mixed configurations depending on the trailer’s electrical needs. A 7-pin harness is common for trailers with electric brakes or more complex lighting.


• Brake controller and other equipment: Trailers with electric brakes usually require a brake controller installed in the Highlander. In many cases, a factory towing package includes this or makes it easier to install. You may also consider an external transmission cooler if you plan heavy or frequent towing.


• Tongue weight and payload considerations: Hitch and trailer weights must stay within the Highlander’s payload capacity and hitch tongue weight rating. A typical rule of thumb is 10–15% of the trailer’s gross weight as tongue weight, but you should verify ratings for your exact model.

In practice, most Highlanders can be equipped with a hitch either via the factory option or an aftermarket install, but you should verify the exact equipment and ratings for your specific vehicle and year.

Choosing the right hitch, wiring, and components

Before purchasing or installing a hitch, consider these factors to ensure compatibility and safe towing performance.

• Check the official towing capacity: Highlander towing limits vary by year, engine, and whether the towing package is installed. Modern Highlanders generally offer up to about 5,000 pounds with proper equipment, but confirm the exact figure for your vehicle from the owner’s manual or the window sticker.


• Identify the receiver size: The common aftermarket option is a 2-inch Class III receiver. Verify the exact size and class recommended for your vehicle and trailer combination.


• Choose the wiring solution: Decide between 4-pin and 7-pin connectors based on your trailer’s needs. A 7-pin harness is typical for heavier trailers with electric brakes.


• Decide on a brake controller: If towing heavier trailers or trailers with brakes, a brake controller is usually required and may be included in the factory package or added aftermarket.


• Plan for additional equipment: For frequent or heavy towing, consider a transmission cooler and revisiting overall payload and GVWR to stay within safe limits.

Evidence-based caution: Always confirm compatibility with your specific model year, engine, and trim, and follow all installation instructions or have the hitch installed by a qualified technician to preserve safety and warranty coverage where applicable.

Installation considerations and safety

Installation can be undertaken by many do-it-yourself enthusiasts, but professional installation is recommended for complex wiring or if you’re unsure about electrical integration and payload limits. The following guidelines help ensure a safe and compliant setup.

• Assess warranty and dealer guidance: Check how aftermarket installations interact with your drivetrain or electrical warranty. OEM towing packages typically align with warranty terms; aftermarket components should be installed by a qualified technician.


• Verify weight ratings: Do not exceed the Highlander’s towing capacity or payload rating. Always calculate the trailer’s gross weight and tongue weight relative to what the vehicle can safely handle.


• Electrical integration: Proper wiring installation is crucial for trailer lights and braking systems. Improper wiring can cause electrical faults or unsafe towing conditions.


• Professional vs. DIY: If you lack experience with electrical systems or heavy-duty mounting, professional installation is recommended to ensure correct fitment, electrical safety, and warranty compliance.


• Legal and safety considerations: Some jurisdictions require trailer brakes or brake controllers beyond certain trailer weights. Ensure compliance with local regulations and safe towing practices, including sway control and load distribution.

With the right package and proper installation, adding a tow hitch to a Toyota Highlander is a common upgrade that supports camping gear, trailers, bikes, or small boats, while keeping safety and performance in mind.

Model-year snapshots and practical notes

Across generations, the Highlander’s ability to tow is tied to engine choices and the towing package. In recent years, properly equipped Highlanders commonly support up to 5,000 pounds. Always verify the exact figure for your year and trim in the owner’s manual or at the dealership.

Current and recent generations (approx. 2014–present)

Most 2014–present Highlanders with the factory towing package or a compatible aftermarket setup can tow up to about 5,000 pounds. The exact rating depends on engine (for example, V6 or available turbocharged options) and whether the vehicle includes the towing package and any required braking hardware.

Earlier generations

Earlier Highlanders had lower towing limits and fewer factory options. If you own an older model, you’ll likely rely on aftermarket solutions, with capacities typically still around a few thousand pounds—though always confirm the exact rating for your vehicle and ensure proper installation.

Bottom line: Yes, a tow hitch is generally feasible for a Toyota Highlander, but the key is to match the hitch and wiring to your specific year, engine, and towing package, and to stay within the official weight limits.

Summary

Adding a tow hitch to a Toyota Highlander is a common and workable upgrade. Determine your exact towing capacity, choose between a factory towing package or a trusted aftermarket hitch, select appropriate wiring (4-pin or 7-pin), and decide if you need a brake controller. Ensure proper installation, respect payload and tongue-weight limits, and stay compliant with local regulations. When in doubt, consult your dealer or a professional installer to confirm compatibility with your year and trim, and to safeguard warranty terms.

How much to install a tow hitch on a Highlander?

The cost to install a trailer hitch on a Toyota Highlander ranges from about $450 to over $1,500, depending on whether you choose a dealership or an independent shop, the specific parts and labor involved, and your vehicle's trim level.
