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 tail light assemblies 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 within the jack storage compartment of 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. 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.

Used video which was a big help
Wiring kit for 2011 Siennadone
Shipping was fast and the video walkthrough for the 2011 Sienna was a huge help.
Great product. Video was "spot on". This was a great project, and I saved a lot of money by doing it myself.
Great productThis product was wonderful.
I just want to say that I have never ordered from another company with better service. These people are really on top of it. Thank you for the excellent service.
Good instructions, long heavy gauge wire to reach front of vehicle was nice. Install was relatively easy and is completely out of sight. Haven't tested yet.
excellent product with great instructions for easy installation
Good product, easy to install, it arrived very quickly! I would definately order through etrailer again!
I had a buddy that was a Stereo installer for a long time install the wireing. It looked easy for him but if i was doing it i would have been a bit confused. Other than that it has worked awesome.
Clear instructions. Easy installation of parts. Most time was gaining access to the tail light areas and running wire to battery.
Installed it on my 2011 SiennaInstallation went ok. However there is no mention of where the brown and red wires get connected. This needs to be added to the intallation instructions. Also if the picture of various steps were in color it would likely solve thei problem. The Etrailer tech support is excellent. Way above average.
The product installation was very easy and the video (Trailer Harness Installation - 2012 Toyota Sienna) made the installation easier to do. The only con was not enough zip ties to properly secure the power wire to the Sienna. Luck has it that I had some laying around the garage.
I purchased the hitch from etrailer for my 2011 Toyota Sienna. I was suprised how fast it showed up on my door step and just as suprised on how short of time it took me to put it on. Start to finish was 35 minutes. It looks great as you can see by the pictures. The wiring harness was just as easy, the hardest thing was where I was going to put the wire thru the fire wall to supply power to the back. All in all I am very pleased with both products.
I would buy from etrailer again, the only let down with the wiring harness is that it did not ship with the wire straps for attaching to the underside of the vehicle. (zip ties were included but not the wire supports/screws to attach to underside of vehicle) Great company.
Worked great for our 2016 Toyota Sienna SE -- straightforward install, especially if you've done anything like this before. E-trailer's video install demos make it a snap. A great value - happy to recommend it to others.
This is a great product. The wiring was thick and didn't feel like a cheap Chinese product. I'm happy with this wiring harness. I installed it on my 2014 Toyota Sienna. Even though the instruction video is not updated for the 2014, the instructions it came with contained a picture of the shroud and where to cut, which was the only difference (shroud size, only one cut needed on the 2014) between the 2014 Siennas and the ones from prior years.
You'll see in the picture attached, I purchased the loom to protect the wire. I would recommend doing the same.
The only thing that would have made more sense to me is if the box attached to the drivers side since that is where the battery is. There would be a lot less wire to route under the vehicle. Other than that, it worked on my first try and I'm happy with that! :)

Its been a year already? Wow! Since I dont have a truck, I use my minivan and aluminum trailer frequently. I have no regrets buying this wire harness and would buy again.
Just received it by way of UPS. I'M so excited to do the install tomorrow!

I wanted a project and a wiring harness for my Toyota Sienna. I purchased and installed the harness myself in an afternoon with a tow hitch project. I use it all daily mostly for my mountain bikes.
all the parts fit my toyota van. this will protect the electronics of the car.

I havent plugged into a trailer yet, but Ive had no interference with the normal operation of the tailturn signal area of my sienna. Everything is working well.
Not for all Siennas. I ordered for my XLE and the plugs were the wrong size. I think this one is only for the SE trim.
The hitch is solid/sturdy. It was easy to install. I use it frequently and have only had one consistent problem. Once attached to my 2013 Toyota Sienna, ground clearance is only 7 inches. See picture. Add the weight of my boat, and that clearance drops to 3 inches. I realize that most of that blame is owned by Toyota, but still, there's at lease another inch or so that could have been gained through improved design of the hitch. I had to add an Air Lift 1000 to bring it back to 7 inches clearance.
The product is fine, shipping was very fast. Packaging was ripped and torn I am surprised that all parts were there.
Parts is great, wish the power line to the battery was just 4" longer that would of made it easier to run the line to the battery.. other then that installation was easy ..
The hitch fit perfectly, looks great on the van and the wire harness installed easily. One suggestion before installation is watch the videos here on etrailer.com and it makes your installation easier!

After a year of use, things are still standing up well I do recommend getting a cable wrap to enclose the wires for their exterior run to their connection point with the trail hitch mount but everything continues to work well. No regrets!
