Features to know about

Plug and Play Simplicity: Custom-Fit T-Connector

Slicing and dicing wires is a thing of the past! The Hopkins Plug-In Simple Vehicle Wiring Harness provides a seamless connection with your vehicle's wiring system. Its custom-fit T-connector plugs directly into existing wiring in your rear cargo area, eliminating the hassle of cutting and splicing. Whether you're upgrading trailer lights or tackling wiring repairs, this harness makes installations a walk in the park.

Master Seamless Signal Integration: Built-In Tail Light Converter

Encountering compatibility issues with your trailer's two-wire system? The built-in tail light converter effortlessly resolves this by merging your vehicle's separate brake and turn signal functions into one wire. This ensures your trailer's tail lights work without a glitch and won’t mess with your car’s lights either. So, trailer signal mismatches become a distant memory.

Resilient and Reliable Connections: Corrosion-Resistant Terminals

Harsh weather and corrosion can wreak havoc on electrical connections, leading to flickering lights or short circuits. The Hopkins harness combats this with protective connection terminals that fight against corrosion. A dust cap and terminal grease packet are included for added protection, ensuring your connections remain solid and dependable over time.

Instant Signal Power: Effortless 4-Way Trailer Connector

Need a reliable 4-way trailer connection fast? With the Hopkins harness, you instantly gain a 4-way flat trailer connector at your vehicle's rear. Compatible with 5-, 6-, and 7-pole adapters, it’s designed to power your trailer’s signal lights immediately, giving you the flexibility for various towing setups without delays.

Hassle-Free Voltage Compatibility: From 24V to 12V

If your vehicle operates on an upgraded 24-volt system, fret not. The Hopkins Plug-In Simple wiring harness is designed to degrade from 24 volts to the standard 12 volts seamlessly. This ensures that regardless of your electrical system's voltage, your trailer's signals will always maintain optimal power levels as needed.

Smooth Rides Guaranteed: Custom Fit for Land Cruisers

Driving a 1993-1997 Land Cruiser? The Hopkins wiring harness fits like a glove. Its plug-and-play feature turns the installation process into a quick and satisfying project, avoiding the frustration of ill-fitting components. Built specifically for Land Cruisers, it ensures the most efficient and straightforward setup, aligning perfectly with your vehicle's factory plug-in port.

Product is awesome! Exactly what I expected and what I paid for. It was shipped and arrived much faster than I thought it would.

I ordered a wiring plug for hooking up lights for a trailer. It was exactly what I needed and it got here faster than anicipated...wonderful



by:
1994 Toyota Land Cruiser

I am very pleased with my purchase. I installed the trailer harness last night and it took me about an hour, and I'm no wiz when it comes to electrical stuff. The product was exactly as described and it was a perfect plug and go. From the order to the delivery the communication was excellent. That is always one of my fears when ordering online, that I will place an order and it will go off into some blackhole and I'll never hear another thing, until weeks later when I get the product that I may not be happy with. Not the case here, etrailer had excellent communication from start to finish. I will recommend this site to my friends and will surely use this site for other purchases.

It installed quite easily. I'm conflicted about how I feel with the rear L & R taillight lead between each other being run internally under the carpeting, but it doesn't seem there will be any meaningful friction or bend radius issues over time.

Perfect! Fast ship!

SO EASY to install , I cannot fathom why anyone would use crimp connectors and "hack" into their wiring harness. Plug and Play is the right way!

Just as if I installed it Yesterday! Did the same thing to my Rav4.



by:

This did exactly the job I needed on my 94 Landcruiser. The connections were perfect fits and I was able to route the wiring down to a new bumper I had purchased. My goal was to get working lights on my new bumper lights, so a little different. This harness allowed me to tap into the stock rear light harness and route wires accordingly.



by:
1993 Toyota Land Cruiser

Great product and very simple to install. I dread any electrical work and especially related to trailer lights. There is always something that needed splicing or the wear and tear on the wiring and the connections. In the fifteen minutes it took to install, made me wonder why I had never looked into these connections before and how much time I had wasted half repairing over the last ten years.



by:

Great company to work with. Wiring harness worked great. Will use etrailer again.



by:
1995 Toyota Land Cruiser

This product fit my 1995 Toyota Land Cruiser perfectly. The instructions were good. Once I located the plugs and pulled them apart the new harness plugs snapped right in - I tested the new lights and they worked the first time. Overall a good product - works as advertised.



by:

This was the first time that I’ve ordered something off the Internet and it bolted directly on with ease. The wiring harness instructions were simple and clipped all together with no hiccups.



by:
1997 Toyota Land Cruiser

I was skeptical of all the 5-star reviews, but this product solved my problem! After replacing my trailer lights, activating the left turn signal caused the trailer hazard lights to flash. I had wasted WAY too much time trying to find a problem with the trailer wiring, but a tester showed the fault was with my vehicle (1997 Toyota Land Cruiser). I was reluctant to believe it because everything was working fine until I changed the lights on my trailer. Perhaps coincidentally, the original turn-signal converter in the truck had gone bad. Replacing it with this wiring harness & converter (33405 or 43405) solved my problem. Installation was pretty straightforward and took less than an hour, even though I was working slowly. I needed to get this done before a long trip, so I opted for one-day shipping. I was very pleased with the product AND the very quick delivery.



by:
1993 Toyota Land Cruiser

Right product, fast shipping, great customer service. I was able to install it in about 10 minutes! Thanks etrailer!



by:

Very simple install! Everything is plug and play so no need to slice into any wiring on my Land Cruiser. Would buy again in a heartbeat.

No problems on installation.

I just wanted to say thank you for making things affordable and having a trustworthy site to buy from. I just noticed you guys even do a monthly payment plan to purchase items. That would really help people who are on a tight budget. Thanks and Happy Holidays!

  • Hopkins Wiring Harness Causing My Trailer Lights To Be Dim
    Hey Cody, The most common issue with trailers having dim lighting is a weak ground connection. I would double check, and even re-ground the ground wire on the vehicle and/or trailers to make sure all of the grounds have a strong connection. Since they all work there is not going to be an issue with the actual harness itself. If you check the grounds and they are still dim let me know and I can continue to troubleshoot.

  • Correct Hopkins Trailer Wiring Harness for 1997 Toyota Land Cruiser
    The Hopkins Plug-In Simple Wiring Harness # 33405 that you referenced is the correct harness for your 1997 Toyota Land Cruiser and is actually the same part as the 43405 model number you referenced. Sometimes we use slightly different part numbers than the manufacturer for organization purposes. Our Wiring Harness # 33405 and the Hopkins part 43405 are one in the same. I have attached the written installation instructions that you can check out as well. You can also see that when you...

  • Will the Hopkins Wiring Harness part # 33405 Work With 24 Volt Systems
    The Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 33405 is designed to plug into a factory port on your vehicle. If the electrical system has been upgraded to 24 volts as it goes through the wiring harness it will degrade it to the standard 12 volts. So as comes out of the factory plug it will still be 12 volts at the factory plug so yes the harness will work.

  • Brake Controller Installation on 1997 Lexus LX 450
    The 1997 Lexus LX450 was not factory equipped with the connector under the dash for a plug and play brake controller installation, so there's not a plug-and-play brake controller wiring option available. To install a Prodigy P2, you'd need to hard wire the controller using our Brake Controller Install Kit, part # ETBC7. The kit contains everything needed to install a brake controller, but your Lexus will need a functional 4-pole trailer connector. If it doesn't already have one, you can...

  • Recommended 4-Way Trailer Connector for 1996 Toyota Land Cruiser

For your 1996 Toyota Land Cruiser, you will want the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 33405. This T-connector harness will plug into the factory wiring behind each of your tail lights. I has an integrated converter to give you the 4-way trailer connection you desire.

  • Wiring Harness Needed that Fits a 1995 Toyota Land Cruiser
    The trailer wiring harness that fits your 1995 Toyota Land Cruiser is part # 33405. The hitch you referenced, part # 41015, is also a fit for your Toyota. You also need a ball mount and hitch ball to complete your setup. I've linked our selection for you, as well as an article to help you determine the rise or drop you need with your trailer. Once you choose a ball mount select a hitch ball to fit. Then use # PC3 for a pin and clip.

  • Will a Trailer Hitch Fit on a 1994 Toyota Land Cruiser with a 315/75R16 Spare Tire
    It looks like the stock tire size on the 1994 Toyota Land Cruiser is 275/70-16. I spoke with my contact at Draw-Tite and he stated that trailer hitch # 41015 is designed to fit on a vehicle with a stock size spare tire. Anything larger would not fit. A 315/75R16 is going to be too large for the hitch to fit properly. If you could carry the tire somewhere else, in the cargo area or on the roof, you could install the hitch. I have included a link to the installation instructions for you. To...

  • How to Install a 5-Way Trailer Wiring Harness on a 1996 Toyota Land Cruiser
    For your 1996 Toyota Land Cruiser you would want to start with the 4-way harness part # 33405 which is a confirmed fit that does not require any hardwiring. To convert this to a 5-way would only require the adapter part # 20036. I attached an install video for how the adapter installs on a vehicle.
