Specs:
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located inside your rear cargo area, behind the tail lights on both the driver's side and passenger's side. You will have to remove some interior paneling to access this harness. Once you've plugged in the T-connector, run the hot lead to the power cable stud on the driver's side and connect the wire using the ring terminal. Then insert the included 15-amp fuse into the fuse holder.
Once installation is complete, the 4-way connector will be stowed in your trunk.
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.

David M - 10/20/2020Frankly working with etrailer is as easy as working with [online retailer], the one big difference is the personal interaction and the review/installation videos. I installed the wiring on my wife's Volvo just by watching the video and I am NOT mechanical in any way. etrailer runs the way, I run my business. Customer-centric, communicative and attention to detail. Well done!! 692803
The vehicle specific videos were very helpful in DIY install. 669755
I have a 2019 Volvo XC 90. It took about 2 hours to install The Drawtite hitch and taillight kit. Taillights worked perfectly. No programming the cars computer. Total price etrailer: less than $300. Volvo wanted $1,600. etrailers sales person: home run. Very nice. 655984
Jason was very professional and helped me addd additional items to my order. The items arrived in two days as promised in great condition. I’ll know more about the hitch when I install it. 642849
The directions are OK except you have to remove the "threshold" before you can remove the side panels. Also there is a little cap over the anchors that has to be removed to gain access to the hold down bolt. The battery on a Volvo 2019 is not in the engine compartment, but under the spare tire. Much easier to tie into. 637916
This was incredibly easy to install with the online video. The wires were all plenty long enough which is where a lot of companies cut corners since copper is very expensive. Thanks for selling a great product, it is appreciated. 484181
Nicholas - 03/14/2019The wiring fits perfectly and is easy to install. I would have given 5 stars if the instructions were easier to read/see. I couldn't even tell what the pictures were because the quality was so bad. I had to take interior panels off and feel around to find where the plugs were. 407507
