Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness. The connection point for the 4-way harness is located behind the rear bumper. The converter plugs into the factory wiring harness behind the interior access panel in your rear cargo area. Connect the lead to 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 beneath your vehicle, near the trailer hitch. Secure with the provided cable ties.


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.


Powered Tail Light Converter with Surface-Mount Technology

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 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.


Curt SMT Circuit Boards

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.

Video Transcript for Review of Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C38KR

Jeff: Hello everybody. This is Jeff at etrailer.com. Today we're going to take a look at the Curt Custom Vehicle Wiring Harness with the four way flat trailer connector for your factory tow package. Now, this is a custom fit part. It is designed to fit the 2001 to 2002 Toyota Tundra trucks with the factory tow package. On a custom fit part like this, I always like to recommend for you to go to our website, use the fit guide, put in your year, model, vehicle, and it'll show you if this will work for your application.Now, this will provide this four way flat trailer connector at the back of your vehicle to power your trailer's signal lights.

It is designed for use with a factory tow package, and it is compatible with the five pole, six pole, and seven pole adapters that we do sell separately. To install this, it does connect very quickly and easily. There's no cutting or splicing of wires. Basically, the tow harness, which is this part here, has the four way on it. This will plug into a connection point that's behind the rear bumper along the passenger side frame rail.

That connector will match this one. Plug it in, and then you'll run your four way out the back. Now, what you also want to do is this module box here. It is a little heavy, so you do want to attach that to a location on nice flat surface so it doesn't bounce around. So, they do include a piece of double face tape that you can use to do that.Now, the harness right here, this harness has a fuse holder in it, and it'll plug into a connector that's under the hood located between the battery and the driver's side fender.

It'll match this connector right here. Once you plug that in, then what you'll do is take this ring terminal end, attach that to the positive battery terminal. Once that's all connected, then you open up your fuse holder, take your included 10 amp fuse, install it into the fuse holder. Once you have that fuse installed, put your cap back on, and you're all ready to go.Now, they do give you a nice set of instructions that'll describe these connections and some extra cable ties to take up any slack in the wiring. Now, this module right here, this is a powered module.

It'll connect directly to your vehicle's battery, and it avoids overloading your vehicle's electrical system. This is constructed using the SMT, which is Surface Mount Technology. Gives you a consistent, reliable performance. It does maximize your trailer light yield and intensity while producing minimal heat, and it also ensures superior operation in rough road condition. Also, if you noticed on the four way, it does come with this included dust cover for your four way, so when you're not plugged into your trailer, you can just put this on there and that'll protect the terminals from any damage or from the elements.A few specs on this wiring harness. The maximum amperage for the stop and turn light circuit is three amps per circuit, and for the tail lights, it's six amps per circuit, but that should do it for the review on this Curt Custom Vehicle Wiring Harness with the four way flat trailer connector for the factory tow package.

2001 Toyota Tundra

Works great as a replacement for the failing factory converter in my 2001 Tundra. Down one star for the double-stick tape failing, but now it's tie wrapped and all is well.

Super easy to install, follow the given instructions, took maybe 10minutes to complete for my 02 tundra!

  • Do All Models of 2001 Toyota Tundra Have Tow Package Connector at Rear of Vehicle
    According to Curt, all models of the 2001 Tundra have the tow package connector located by the driver's side frame rail as shown in the provided photo. If you'd like a mounting bracket, I'd recommend # 18140 that would attach to the hitch crossbar using the included pipe clamp If the hitch doesn't already have a standoff for the bracket to mount to and the # 18144 bracket.

  • Parts Needed to Install 7-Way and Brake Controller in 2002 Toyota Tundra
    We can definitely help with a 7-way and brake controller for your 2002 Toyota Tundra but your vehicle was not pre-wired for a brake controller install so the install would be a little more involved. You will need to start with a 4-way (if you do not have one). For that you would want the # C55378. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7....
