Installation
This custom-fit T-connector plugs into your Toyota Highlander's wiring harness. The connection point for the 4-way tow harness is located behind the interior trim panel in your rear cargo area. The converter plugs into the factory wiring harness beneath your dash, on the driver's side. Once you've plugged in the converter, insert the included 10-amp fuse into the integrated fuse holder.
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. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
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 Toyota Highlander'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 Toyota Highlander 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.

Good overall experience for an unskilled mechanic. Arrived on schedule (with a few bumps and bruises on the shipping box). Installed easily, as advertised with instructions which also included diagrams for cutting out the underbody panels to be reinstalled. Excellent! Wiring was a snap as well, even managed to fish wires thru an existing/sealed opening to run them under and behind bumper panels.72464

Product was received promptly on-time after excellent customer service. Fitted easily by mechanic in less than half an hour. Worrks perfectly well, with good instructions, but unusual that connection is from within vehicle, rather than external. Great service !48257

The product was delivered on schedule and the price was 25% of the OEM part from Toyota. General installation was pretty straight-forward, but the directions (both on the video and in the package) were not very explicit about the "in line fuse" installation process. So, I left it out, thinking the wiring harness was complete as received in the package. This caused me some troubleshooting problems, but the problem was identified and resolved by the Toyota service shop. Product now appears to work as promised.37323
