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 tail lights. You will have to remove the trunk floor coverings, storage trays, and the rear and side scuff panels to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. 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 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.


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.

Today, we're going to be taking a look at the Curt T-Connector Vehicle Wiring Harness with the 4-pole flat trailer connector. This is designed to fit certain years of the Scion IM. It's going to provide a 4-way flat connector at the back of your vehicle to power your trailer signal lights. The unit is compatible with 5-pole, 6-pole and 7-pole adapters. Adapters are sold separately. It's going to come with a dust cap for the 4-way connector, that way you can cover up the connection points when the plug's not being used.

The unit's going to include a tail light converter. This is going to ensure that your vehicle's wiring matches that of your trailer's. The powered module connects directly to the vehicle battery through all the wiring. That's really going to help avoid overloading the vehicle's electrical system. The unit's constructed of surface-mount technology, or using surface-mount technology, which is going to offer consistent, reliable performance. What that does is it simply maximizes the trailer light yield and intensity while producing minimal heat, and it's going to ensure superior operation, even in rough road conditions.

Now, one of the main benefits of this system is how easily and quickly it's going to connect. All you have to do is locate the connection points behind your tail lights. You can see, you have 2 sets of connectors. The set with the yellow wire, that's going to go to the driver's side of the vehicle. The set with the green wiring, that's going to go to the passenger's side of the vehicle.

Locate the connection points. Push the plugs into the ports. They're going to match up perfectly. This is a custom-fit wiring harness, and they're going to snap-lock together for a nice tight, secure fit. Once you have those connected, you can make your ground connection. That's going to be the white wire, right here, with the ring terminal attached to it.

Make the ground with the included grounding screw. Then, you'll want to find a nice flat, out of the way location to mount the converter box. You can get that mounted using the included double-sided adhesive tape. Next step is going to be to run the hot lead to the vehicle battery. The hot lead is going to be the black wire here. It's going to get connected to the bundle of black wire with one of the included butt connectors. The other end of the black wire goes to the vehicle battery, gets another butt connector attached to it and connects to one half of the fuse holder. The other half of the fuse holder gets the ring terminal attached to it and that connects to the positive post on the vehicle battery. It does come with a 10 amp fuse. Goes directly in the fuse holder and it's got the fuse holder cap to protect the fuse from the elements. Once your installation is complete, the 4-way connector's going to be stowed in an out of the way location within your rear cargo area, that way it's always easily accessible. If you have any loose wiring or excess wiring, you can use the included zip ties to secure your wiring up and out of the way. The unit does come with detailed installation instructions, as well as a wiring diagram, to help walk you through the installation process, step by step. When it comes to the maximum amperage for the stop and turn lights, we're looking at 3 amps per circuit. For the tail lights, we're looking at 6 amps per circuit. It's also recommended that you use a small amount of dielectric grease on all your electrical connections, like the plugs on the vehicle and the 4-pole connector itself. That grease is really going to help prevent corrosion. If you need some of that, it is sold separately. You can find it right here at etrailer.com. That's going to do it for today's look at the Curt T-Connector Vehicle Wiring Harness.

See what our Experts say about this CURT Custom Fit Vehicle Wiring

  • Trailer Hitch Recommendation for 2017 Toyota Corolla im
    The Curt trailer hitch part # C11420 has a 2,000 lb trailer towing capacity which would easily be enough capacity for a stand up jet ski or dirt bike since those vehicles and the trailer associated with them are pretty small and lightweight. I attached an install video for this for you to check out as well. You would want to check the owners manual of the vehicle to be sure it has the capacity for the trailer as well. The overall towing capacity for a vehicle is that of the lowest rated...

  • Recommended Trailer Hitch For 2016 Scion iM
    The trailer hitch we offer for your iM is the Curt Trailer Hitch, part # C11420. This is a Class l hitch and it has a 1-1/4 inch receiver opening. This will work great for light towing. Curt requires a stabilizing strap like part # 18050 to be used for any non-trailer items used in the trailer hitch. If you need a 1-7/8 inch hitch ball I recommend the Euro style drawbar, part # C45571 and for a 2-inch you can use part # C45572. for a trailer wiring harness you can use part # C56309.
