Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in the rear cargo area. You will have to remove the plastic threshold cover, side panels, cargo trays, and 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.
A ModuLite power module is built into this T-One connector. 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.

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.2024 Sienna XLE installed easily, just plugs in, but side panel removal takes some thinking. Watch the video for similar products. Get a cheap panel removal tool and life is easier! Used small machine screw to bolt relay box above the small removable panel.
See photo. If ever needed this allows access to the units fuse holder without having to go through the work of removing side panels again. Routed trailer wire out bottom of this small panel and wiring then stores neatly in the side box.
This worked great on our '22 Sienna. Things plugged right in. I got a little creative with the mounting and wire routing. I mounted to the back side of the plastic access panel, then cut a notch in the access panel to run the wire through, into the rear cargo area. It's worked out well for me. I have the flat four with wire coiled up inside the rear cargo area of the vehicle, which wouldn't be ideal for somebody using the trailer all the time, but for me, using the trailer 5-10 times/year, it's just fine and keeps things out of the weather.
Fits perfectly on my 2022 Toyota Sienna XLE and was very easy to install.
Simple installation. Good quality product. I've been using it for over a year now with no issues.
Starting at 5:15 out of 12:08 hitch installation you tube video by MasterJacks, followed his guide. Broke plastic installation pins, bought Ford plastic pins at Autozone, Toyota pins not close to OE. Used adhesive backed hook and loop fasteners to mount electronics box. Everything works.
This part makes it easy to have a complete hitch setup
It was simple to install!!! It was just as it was described.
Works well. Instructions OK, though could be clearer.
Wiring harness connected right up to the 2022 Toyota Sienna. It comes with some Tape and mounting instructions that didn't quite line up with a Sienna that had a spare tire. I don't like 2 sided tape because I don't believe it will last in a hot car. I got a couple of self tapping screws and mounted the plastic box to the aluminum spare tire mount. Also used a self tapping screw to attach the ground to the aluminum spare tire mount.
Installation was a breeze. No wire splicing. Plugged into my 2021 and it's been working great!

still going strong!
Just got it 2 hours ago and it is all installed. Did a hitch receiver as well. Wiring went good. Used the rubber plug to run it through so it’s permanently tied to the receiver. Thanks!
Works great on my Sienna. Easy install once I got over popping interior panels off my brand new car
Hooks right up to an open connector behind the spare. There’s a rubber plug that goes through the bottom of the car, I used a knife to cut halfway through it and just slid the harness into the middle of the plug if that makes sense. Ran the wires to the hitch without a problem. Dropped the plug back in and it basically molded around the harness wires. Hooked up a trailer and it worked great
So far so good. Works on my small lawn mower trailer just fine
Direct fit to factory wiring harness. Easy to install. Using for a year now without a single problem
Easy installation with clear instructions. Very well packaged. Arrived very fast and the customer service was great! I knew where my product was at all times and when it arrived at my house.
Easy to install, works exactly as advertised. Had to modify the installation slightly to clear the spare tire, but it was easy.
It takes a 5 minutes to complete a gob.
On a package picture it shows different type of wire harness but inside is exactly what I needed.
Thanks again.
Incredibly easy install. The Sienna has a wiring harness behind the spare tire so it was plug and play. I was able to use one of the rubber grommets to route the wires to the hitch.
Solid trailer hitch, works great. Easy to put on. I like that there are places we can attach ratchet straps for our rooftop kayaks too.
The 2021 Sienna has the connector underneath the spare tire, two mounted screws perfect for the grounding wire, and a rubber cover for easy access to underneath the vehicle to route your 4-way.
The trailer hitch receiver was easy to install, but the instructions were also wrong (removing the cover underneath the car was on the driver side, and not the passenger side). 5 stars as long as they get the instructions fixed so people don’t unnecessarily tear apart their car!
Excellent. Five stars.
Very easy to install, took me about half an hour. Only minor complaint is that there were a few small spots on the hitch that were not powder coated, so I’ll touch those up with enamel. I was also able to trim the underside panel a little more conservatively so as to leave the aft bolt attachement in place. Maybe not a big deal but given that it’s plastic and supposed to protect wiring from salt and road grime, I figured leaving as much intact as possible would be a good thing. etrailer shopping and follow up were great
The T-One harness from eTrailer looks great. The custom plug fits the Toyota Sienna 2022 Platinum harness making the electrical hook-up easy.
Easy to install. Would be great if the grommet that goes through the body would be supplied with the kit.
