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.
Features:
Specs:
This custom-fit T-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 connector, run the hot lead up to your car battery. Connect the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.
Once installation is complete, the 4-way 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.

Works as intended. My second purchase on etrailer.com very satisfied. The etrailer YouTube page is also a great resource.
Everything went smooth with the wire installation except your power line is too short it should be at least a foot longer to comfortably reach the battery
I too installed this at the same time as the Draw-Tite hitch. I installed mine into a Promaster City Wagon instead of the Cargo Van. The install is a little different. You have to remove the screws holding the speaker panel in and then pull up to remove that part. Then you have four screws under the speaker panel plus a couple more holding the larger panel. You do not have to completely remove the larger panel. Just pry and hold it back about a foot to allow access to the hole described in the video. Everything else is the same EXCEPT where the trailer wiring has to be stored and exit the side metal. There is a little triangular plastic panel near the bottom. This panel just pops out and trailer wiring can be hid behind it.
I do wish the trailer wiring was long enough to be run to the outside and down by the hitch but it is just too short.
I also found the power wire to be about one foot short of ideal. It works, but it is not the ideal length.
This is actually a good wiring kit but I will mention two things. The instructions want you to mount the wiring junction block behind the right tail light. I think it should be pointed out that there isn’t room directly behind the light but there is room in the body cavity directly behind the light enclosure.
When you connect the harness for the first time to each of the tail light plugs take the time to disconnect them again and check to see if any of the pins in the connector got pushed in. If so use needle nose pliars to gently pull on the loose pin until you feel it lock onto place. I mention this because it is easier to double check while you have the tail light removed than it is to take the light out again.
Without the trailer video this would have been a difficult install. Instead of installing the electronic module with double-stick tape, I found it easier to mount it using the same bolt & nut assembly I used for the grounding wire install—I provided the bolt, nut and star washer. As with all other reviews for this product, the black wire going from the electronic module installed on the rear passenger side of the van to the battery is short by at least two+ feet. Suggestion for the RAM Pro Master City cargo van; the instructions say the harness going to the trailer can be stored in the snap-on panel in the rear. I brought my harness out through a small vent in the corner.
Everything was included and I installed it in about an hour. Two suggestions I would offer is to provide about one more foot of the power wire and consider wire nuts rather than butt connectors. Without a proper tool the butt connectors don't work so well but wire nuts don't require any special tool. Hope it works!
Easy to install. I installed the hitch as well so I had the bumper off which made running wires easier. You do have to run a wire to the battery but it's easy to run on this vehicle. I've done thousands of brake control installs and this is one of the easiest especially with the plugs.
The hitch receiver & wiring kit for my '17 RAM ProMaster City was perfect. Installed easy & work great! Saved me a lot of money, BIGTIME!!!
This is second hitch from etrailer.
Shipped and received on time.
The best reason i buy from etrailer is the great video's
that show how to install.
Seems like there is always something that would hang up the install
if you did not view video.
The first powered trailer light converter didn't last 5 months. I really don't know if it ever did work as the first time I used it it did not work. Ordered another and will see about this one.
Product did not install as per instructions. The module was to be attached to the inner passenger side after quarter panel with double side tape. The space shower on the instructions and video is not there on our 2017 model. the harnes worked as designed.
The product was easy to install and works great the video was dead on and I didn't have access to a lift but it was still very easy to do. Great product.
I watch the video that each trailer put online and it seemed easy enough and I was able to install it and begin pulling my trailer right away. It was the first time I’ve ever done any work on a vehicle before and it went together smoothly
Following the instructions included, I found the harness with the plug was too short to reach the drivers side of the hitch, I had to lengthen that. other wise everything else went as instructed!
power wire for 118719 was 1' short. Otherwise, good.
everything that I have ordered from etrailer has been spot on and high quality. thank you very much.
just had problem with retracted pin in plug not making connection but easy fix after locating problem
great product. easy install with you tube help.
Streamline service

Fine! Power cable to battery was not long enough. I used my own cable to connect the harness to the battery
