Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Not the best quality some wire exposed on harness , Also didn’t fit my 3rd gen 4runner well in the fact the box is on the right side with no way to put the 4 pin trough the body. (on the left side there is a thru port ) would not recommend .

Only use it Twice a year, May and October. so far its worked fine.

2002 Toyota 4Runner

Everything arrived in a timely fashion and, with a little help from my jack, I got the trailer hitch on my 2002 4Runner. All was very well packaged, and I appreciated that the shipping was included in the price.

The wiring kit was a different story. I know that you have trouble even within brands and years dealing with different wiring packages and the manufacture of the car is not very good at finding the plug-ins for the wiring harness for the trailer (I went to Toyota and the parts man could not find it). I finally took it to a body repair guy since I knew that I would break some of the interior paneling if I tried to take it out. Sure enough, it was conveniently located--but no one, not the manufacturer of the wiring harness or Toyota could tell me where to look.

It is now in place, after two or three days of periodic hassle, and working fine.

The Customer Service for e-Trailer is another matter. I am not telling you all something that the company does not know. The help lines are so swamped that the don't call you back, even though the people I finally did talk to tried to help. They even encouraged me to send pictures of the plug-in point I found--except, surprise, surprise--the website rejected my e-mail with the picture because the inbox was 'full.'

eTrailers needs more employees--and needs to pay them more so that they don't get frustrated with their jobs and move on.

But, all in all, despite the hassle with communication, it was a good experience.

My '96 4Runner hasn't had operating trailer lights for a little while. The company that repaired it last did not place the control box in spot where the elements could do no harm. Winter weather and moisture caused a short and there you go. No lights.
Toyota dosn't make a replacement part any more.
Your C55341 was the ticket. After I removed all the old wiring and spare tire which needed air by the way. I was able to do a simple pulg and play and feed the four-pole connector thru the channel like OEM. Ran a meter test. Plugged into the trailer connector everything works as it should. Thanks for the hook up.

I purchased this item to replace a failed original equipment unit in a Toyota 4Runner. This product is an easy to install plug in device. It is rated to handle more current than the original unit & has worked well since installation.

It has been a year. The 4Runner tows intermittently. No problems with trailer lights since this unit has been installed.

1998 Toyota 4Runner

We have a '98 4runner and needed to rent a trailer but our trailer blinkers were not working.

I ordered this wiring harness and replaced the old one. We tested it and it works great!
The product was incredibly easy to install (took about 30 minutes) and comes with great instructions.

Thanks for continuing to make this product for those of us with old cars!!



by:
Toyota 4Runner

Great product, fit and worked as described along with great instructions. My only suggestion would be to have the final wiring which goes out of the vehicle to the trailer hitch location be able to be "unplugged" from the black control box so it would be easier to wire it through the floor access of the 4Runner as the routing hole is too small to fit the flat trailer connector. In any case, I worked it out and now have fully working trailer lights once again.

etrailer was very helpful and shipped q uick

I am Extremely Happy!!! : ) with my trailer hitch order. Installation was smooth and easy. It took me less than an hour to install including the light kit. I wish all my projects would go this well.

Much Appreciated.......

The wiring harness went into my trailer better than harness when it was new back in 2001!



by:
1999 Toyota 4Runner

Wiring harness is easy to install; First one in '99 Toyota 4 Runner was installed by hitch installer in 08 and until a short in trailer light shorted left turn signals never had any problems; if new one last 10 years will be great



by:
1997 Toyota 4Runner

Worked for a month the nothing rechecked all wires and was still good but wouldn't let powers goto the connection for trailer. Forgot where I bought it from and I'll buy a new one now that I was the email



by:
1997 Toyota 4Runner

This unit was replacing a dealer installed unit from 20 years ago that recently died.
Pretty easy to fit even for a non mechanic like me! It really was plug and play. The only tricky part was getting the old harness connectors off. I guess after 20 years they had welded themselves together nicely. Once that was done, the rest was straightforward. Thanks Etrailer!



by:

Needs a small connector for the trailer wires to run though the frame. Directions advise for you to roll it up and run it out of the back when needed instead of coming out from under the vehicle.



by:
1997 Toyota 4Runner

I received the harness on Saturday at 1:00 and had it installed and working properly by 3. Would have been quicker if I had followed instructions on video. I had left and right crossed by using colors on vehicle. Other than my error no problems.



by:

Good product works well.



by:

the hitch and accessories work great. everything was easy to install. did it all in about 2 hrs.



by:
1999 Toyota 4Runner

What a breeze to install, maybe a tip on how to get the wiring to the outside of the vehicle would be helpful, other than out the tailgate.



by:

plug in simple

Great experience from ordering to receiving. No disappointments in the products as well.

Everything was just as ordered. Shipping was quicker than originally said.

Items ordered were good quality and have held up well. Worked as intended which is all I ask.

  • Trailer Hitch and Recommended 5-Pole Trailer Taillight Wiring Harness for 2002 Toyota 4Runner
    For a hitch, you can't go wrong with the Curt Class III, part # C13087. For a 5 pole trailer wiring harness, there's a couple of ways you can go. You can install a 4 pole trailer connector like the # 118341 and use a 4 to 5 pole adapter like # 20036. The extra blue wire on the vehicle side taps into the reverse light circuit on the 4Runner. Or, if you'd prefer to avoid using an adapter, you could hardwire in a 5 way taillight wiring harness/converter, part # 119177KIT. The # 119177KIT...

  • Troubleshooting 4-Way Flat Trailer Wiring That Blows Running Light Fuse in 1996 Toyota 4Runner
    The problem with your running light fuse blowing as soon as you turn on the 4Runner headlights could be caused by any of several problems. One possibility is that the wiring harness you have on the 4Runner does not have the required current capacity for all of the lights connected to the running light circuit. We offer two 4-pole harnesses for your vehicle; part # 118341 and the higher-current-output Curt harness # C55341. If you recently added extra lights to that circuit, then that could...

  • Parts to Add 4-Pole and 7-Way Trailer Wiring Harness to 1998 Toyota 4Runner
    The 4-pole trailer wiring harness kit I recommend for your 1998 Toyota 4Runner V6 is the Tekonsha harness # 118341. We have found that their wiring products are the most reliable. The harness plugs in at your taillight connectors and apart from that requires only a ground wire ring terminal be installed. If you wish to convert these basic lighting signals to the 7-way connector format you can add adapter # 37185. But if you wish to have a fully-functioning 7-way with the three additional...

  • Parts Needed to Add a 7-Way Trailer Connector and Brake Controller to a 1999 Toyota 4Runner
    To add a 7-Way trailer connector to your 1999 Toyota 4Runner it will need to be hardwired in. The first step to accomplish this is to install the 4-Way, # 118341 or # C55341. Either one will work. Then to add the 7-Way and wiring to install a brake controller you will need # ETBC7. I have included some links that show and explain the ETBC7 installation for you. For a brake controller I recommend the P2 # 90885 because it is easy to set up and use and it is reliable.

  • Troubleshooting Curt # C55341 Wiring Harness Installation in 1997 Toyota 4Runner
    Thank you for your recent purchase of a Curt wiring harness # C55341 from etrailer. The ground wire connection, which you note you have already re-checked, would indeed be my first suspicion based on the harness' behavior you describe. It can often happen that a weak ground will let just enough current to pass to allow some lights to work but not others. Turn signals, since they do not remain on at all times, draw less current and may often be the function that works while a function like...

  • Best Trailer Wiring Harness to Add a 5-Way Flat to a 1996 Toyota 4Runner
    To add a 5-Way flat trailer connector on your 1996 Toyota 4-Runner you have a couple of options. First you can use hardwire installation kit # 119177KIT. I have linked the installation instructions to the right. The other option is to use a plug and play 4-Way harness, # 118341 or # C55341. Then you would use a 4 to 5-Way adapter, # 20036. If you want to avoid hardwiring as much as possible, then going with the second option would be best.

  • 1997 Toyota 4Runner Trailer Hitch and Wiring Recommendations for Towing a Trailer
    I recommend picking up the etrailer Trailer Hitch Receiver # e37KR and the Curt T-Connector Vehicle Wiring Harness # C55341 for your 1997 Toyota 4Runner. The etrailer hitch has a matte black finish that's more durable than the glossy black finishes we see on other hitches, and then the wiring tees in behind your tail lights. You'll also need the mounting brackets # 18144 and # C83DR to keep the 4-Way connector near your hitch receiver for easy access. I also recommend checking out the...

    If I were you I would go with the Curt Custom Fit Vehicle Wiring # C55341. This isnt one of the wiring harnesses you referenced but I believe it would be your best choice because of how easy it would be to install and because it would be exactly what you need to provide you with a functioning 4-way at the rear of your 1999 Toyota 4Runner.

  • Comparing Curt and Tow Ready Trailer Wiring Harnesses for a 2001 Toyota 4Runner
    There is not much difference at all between Tow Ready harness # 118341 and Curt harness # C55341. Both install the same way and work the same way. The Curt harness is rated a little higher at 3 amp per circuit for stop/turn lights and 7.5 amps for tail lights. The Tow ready harness is rated for 2.1 and 4 amps. The way the internal parts are arranged is a little different as well. The Curt converter has all the bips and bops attached to one side of the circuit board. The Tow Ready harness...
