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 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 beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


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.

  • Does Tow Ready Custom Vehicle Wiring # 118458 Require a Battery Connection, 2003 Pontiac Vibe GT
    The Tow Ready Custom Fit Vehicle Wiring, # 118458, does not require a direct connection to the battery when installing and can be used on your 2003 Pontiac Vibe GT. However, the benefit of a system that does include a direct connection to the battery, like Curt Custom Fit Vehicle Wiring, # 55057, is that it protects your vehicles sensitive wiring from too much amperage draw from the trailer lights, which could damage the electrical system on your 2003 Pontiac Vibe GT. The fuse protected...

  • Troubleshooting 4-Way Trailer Wiring on 32003 Pontiac Vibe
    With the voltages being at 0 going into the unit, it sounds like there is either a bad fuse for those functions or the module has gone bad. If you check the wires going into the module with a circuit tester like # PTW2993 and get function, but don't get function on the output side, then that will confirm the module is bad. Since it has worked so well for so long, I recommend the replacement of the same Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 55057....

  • Trailer Wiring Recommendation for a 2003 Pontiac Vibe Towing a Yakima Rack and Roll Trailer
    The Curt Wiring Harness part # 55057 that you referenced is the correct wiring harness for your 2003 Pontiac Vibe. This unit should do very well to power and operate the taillights of a Yakima Rack and Roll trailer like part # Y08107. The trailer will pull about 9 amps total, whereas the # 55057 is good for 6 amps per circuit. Which is more than enough.

  • Difference Between Available Trailer Wiring Harnesses for 2004 Pontiac Vibe
    The powered converter on the Hopkins Plug-In Simple Vehicle Wiring Harness # HM11141425 and the Curt T-Connector # 55057 will require a direct connection to the vehicle battery to power the trailer lights. This will essentially protect the vehicle wiring and electrical system from damage. Because these harnesses use a powered converter, it will have a higher amperage rating when compared to alternatives that have a standard converter. With this in mind, if you only plan on towing a trailer...

  • Trailer Wiring Options for a 2005 Pontiac Vibe GT
    There are 2 possible trailer wiring options for your 2005 Pontiac Vibe GT. The Tow Ready Custom Fit Vehicle Wiring, # 118458, that you have referenced would be the easiest to install. It has 3 sets of connectors and a ground wire. The 3 sets of connectors simply plug in line with your vehicle tail lights. The ground wire gets connected to a bare metal surface or existing ground point. To get access to the connection points, you will need to remove the rear cargo area floor panel (as if...

  • What is the Correct Curt T-Connector Vehicle Wiring Harness for a 2005 Pontiac Vibe
    The correct Curt T-Connector Vehicle Wiring Harness for a 2005 Pontiac Vibe is part # 55057, not part # C53KR which is for a Kia Forte as you mentioned. Therefore, if you wanted to get your money back then you would need to return the Curt T-Connector Vehicle Wiring Harness part # C53KR and order part # 55057 instead.
