Tekonsha Custom Fit Vehicle Wiring - 118801

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • Tekonsha

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points in rear cargo area
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes ModuLite to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 5 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the rear threshold plate, privacy screen, storage covers, floor covering, and rear interior trim panels to access this harness.


Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way flat connector will be stowed in your rear 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.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One 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 your trailer. This power module functions as a tail light converter to combine 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.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

2019 Toyota RAV4

Hitch and lighting kit installed fine, but the videos didn’t mention differences in the 2019 RAV 4 Hybrid from the non-hybrid. I wanted to let you know about those. HITCH Not sure if this is solely a hybrid issue, but there was what was either a shipping tie-down or tow point bracket that required permanent removal, as it was right in the way of the hitch cross member. It’s quite heavy duty. Comes off easily, requires removal of two bolts. Passengers side, mounted on the bottom of the frame rail. I have included a photo, but not while it was on the car, I was focused on the install. I managed the install by myself, no lift, required jacking up at the rear jack point on one side to be able to slip the hitch up behind the chrome exhaust tips, as the distance between them is less than the width of the hitch. Also, appears the foot activated rear hatch auto lift will not work with the hitch, which is what Toyota said, but not what e-trailer said when I sent in the question prior to purchase. It would not have made a difference in my decision to buy. See attached photo WIRING KIT Very pleasant surprise, the battery on the hybrid is in the rear, passengers side below the passenger side panel. Running the power cable is a breeze. The battery is accessed by two removable panels, but just as in the video, I felt more comfortable nearly removing the large side panel to access the light connector. Also, I have the premium stereo, which as a woofer in the drivers rear panel. This does not cause any problems, but is worth mentioning to potential installers so they don’t get worried.

Easy Peasy. Took me about 30 mins to install hitch on the new Rave Hybrid. Didn't even jack up the vehicle. Car was shiney new so exhaust hangers slid right off. Supported muffler w a stack of 2X4s. Removed access stickers and slid the hitch in place. Shimmed it up with more scrap 2x4 pieces. I have limited tools here at the winter house in Myrtle Beach, but 19mm box end got er done! Slid exhaust hangers back on, good to go. Wiring harness will have to wait a few weeks. Very happy, will use next week to drive to Dallas with Bike carrier on the back.

This was a great fit for my 2019 Toyota Rav4. It took me roughly 45 minutes to install with my intermediate skills. The biggest pain was that the RAV4 has a plastic undercarriage which hides a lot of things, I had to take that down all along the driver's side from the rear axle up to the engine compartment. It wasn't technically difficult, but it was an added step I didn't foresee, to tuck the wiring inside of that rather than leave it exposed. It works great with my small trailer lights.

Pretty easy install. Instructions look overwhelming at first. Check out the etrailer install video and you’ll realize how crazy easy this is to do. It’s basically plug n play. I have the Rav4 prime and I used the hybrid battery in the rear with no issues. Here’s a tip the instructions don’t tell you. Connect the black power cable to the module first before sticking the module to driver side body panel. Otherwise you have a small space to work with and it’s difficult to reach in and connect the wires. Good luck!

It's a tight fit for a 250lb guy under this car. Make sure you have ramps to drive it up on or something similar. Aside from routing the power wire, it's a nice easy installation. Everything is included in the kit.

2021 Toyota RAV4

I waited for back order on the Tekonsha wiring harness, and am very glad I did. It is excellent, easy hook-up and works great. The only challenge was routing the power wire under the car without a lift available. I did use ramps, but that only lifts one end. Took my time, and I'm very pleased with the outcome. The kit includes everything you need and the installation video on the etrailer website is invaluable--watched it twice before starting. It would help if they included extra crimp fittings--I damaged a couple and had to try and salvage them. You can't miss with this product!

Works as described and the video was very helpful. If they want to improve the harness and video for the Rav4 2019, I would make the wire between the connectors a little longer. There is a square cut-out in the frame that the connector would snap into. Needs a few more zip ties and I needed a longer zip-tie for near the battery. The video shows that the connectors shrink-wrap, but mine wouldn't. The video doesn't show where to run the wire from the T to the battery. I zip-tied it to the break line and went through a grommet under the rear seat. It was accessible from the rear storage area if you take out the panel behind the spare tire. Installing the harness was easy. I spent most of the time taking off and reinstalling the panels under the car and in the storage area. There are many different screws and connectors that hold the panels.

Very easy install however they do not discuss the Hybrid that has the battery in the rear passenger corner of the trunk which eliminates the need to run a hot wire all the way to the front. This cuts about 30-45 minutes off the time of install.

It's a little ridiculous that in 2021 with a crazy technologically advanced Rav4 PHEV you still have to wire in the trailer wiring like you did 20 years ago, taking apart all the trim in the trunk. However so, this kit is very high quality and the e-trailer video on how to install it is excellent.

I called around for a hitch for our 2019 Toyota RAV4 and was told by numerous sources that they couldn't get one by the time I needed it, to take our granddaughter to grad school at the University of Michigan from the Atlanta area. Sold I started searching the internet and found, in stock, at etrailer.com. I received it 2 days after I ordered it and had it installed today. I bought Draw-Tite because that is the brand I used for many years with my company cars. Overall this was a very good experience and I definitely recommend etrailer.com

This is an excellent kit that as another reviewer mentioned fits very easily in the hybrid model. you are are able to route the power wire to the battery at the same time you route the passenger side signal wires. Done and done. Also worth mentioning is a 6mm x 1 tapped hole in the frame.(You can see the hole in Ryan’s installation video when he goes to drill the self tapping screw in place) I assume this is where the relay would be grounded if the wiring harness was installed from the factory. You don’t need to use the self tapping screw. You can simply use a 6mm screw. Just make sure it grounds the wire correctly and it works perfectly.

I received the wire harness and mounting bracket for four flat and everything looks great-I’ve just received them so haven’t had time to install yet, but I’m sure if they are as precise as the hitch (which fit perfectly) it will be no problem installing-so I’m very pleased with your service and products, thanks

The hitch and wiring are pretty good quality. No real complaints. However, the packaging was totally inadequate. The hitch is basically shoved in a box without any additional padding or reinforcement. The box was tore open at multiple places and the hitch was exposed to damage.

Rob gave a great video, Huge help with the installation. He is a natural in front of the camera. The prices and the products are very good . I have used them for many projects over the years. Only critic, is the butt connectors are poorly designed and do not make a good solid connection. Have to back them up with electrical tape.



- 118801
by:

This is my first time ever installing a hitch and wiring harness, but based on the experiences others have had I think this is one of the simpler harnesses to install. Beware, you will need to use some basic tools, but you don’t cut into any of the factory parts, so it feels less stressful if you make a mistake. It comes with a female/male pair so you can just disconnect the factory taillight plugs and insert these plugs. The video on this page was extremely helpful in the installation process! I have a hybrid, so the only difference was that the 12V battery is in the back passenger side of the car. This actually made the process significantly easier. Overall, it took me about 1.5 hours to install, and I'm no car expert!

I used the wiring harness on a 2021 Rav4 Hybrid. Once I figured out what the right connector was on the car, it all went together very smoothly. With the hybrid, the battery is in the rear right corner of the car, so attaching the wire harness wire to the battery was even easier. The installation video was very helpful.

I used this to wire trailer lights for a 2020 Toyota RAV4 Hybrid. Very easy to install and instructions were well written. It took me about 1/2 an hour from start to finish. Only odd item with my RAV4 Hybrid is the battery is in the back of the vehicle so there was no need to run the ground to the engine compartment which saved a ton of time. I'd highly recommend this easy plug and play harness.
