Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your 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 tail light converter is built into this T-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 the trailer. This converter combines 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.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Just what I needed!
This wiring harness kit was a perfect fit - all connectors and wires were just what was required. No cutting or spicing taillight wires. Great installation instructions along with every fitting needed to complete the process. I would give this 10 stars if I could!

Still 100... great product!
Product is well made. Installing is relatively straight forward. Running cable to the 12v battery is not straight forward. I found a way (on Hyundai Venue) to run cable to the rear of car without drilling holes, without touching any metal and all inside the car 100% hidden. Running this 12v cable took longer than installing the converter box (and associated connectors).

Update. Product did not work out well. In fact this product was faulty and I purchased an other one which worked correctly. I was asked to send faulty product back at my cost. Unacceptable. So I simply took it apart and recycled the electronics.
Arrived 1 day early. Will buy from etrailer agin
Fast shipping
everything good except for original back order. very professional.
Got it all installed fit perfectly
