Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the rear bumper, on the driver's side.


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 plug on your automobile and the 4-pole connector itself - to help prevent corrosion.


Tail Light Converter with Surface-Mount Technology

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.


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.

The product fit and worked perfectly, when no one else even carried it. Auto zone sold me one that didn't fit. The only problem was not knowing when it was going to arrive. It only took 7 days with standard shipping, but there was no estimate with the order, and the tracking in the email confirmation only said "on route". But hey - works great!

  • Trailing Wiring Harness Installation in a 1997 Acura SLX
    The trailer wiring kit for your 1997 Acura SLX that you referenced, Curt Wiring Harness # C56175, is a hard-wire type that requires cutting and splicing of wires. Since vehicle manufacturers are not 100-percent consistent in their use of wire colors, the only reliable method for hard-wiring a trailer harness is to use a circuit tester such as # PTW2993 to test the function on each wire (while a helper activates the various functions on the vehicle). A simpler alternative is to use a custom...

  • Location of Vehicle Side Connection Point for Trailer Wiring Harness Installation 1994 Isuzu Trooper
    According to Tow Ready, the connection point is located underneath your 1994 Isuzu Trooper on the driver side between the rear wheel and bumper. The plug is hidden as it is attached to the back side of a large rubber grommet. According to the illustrations in the instructions, the grommet should also be behind or otherwise near the exhaust. I have attached the installation instructions for reference. If you find the grommet but the wiring harness is not attached, it could have fallen off...

  • Brake Controller Recommendation for 1998 Isuzu Trooper Towing Camper Trailer

  • Trailer Wiring Recommendation for a 1995 Isuzu Trooper

  • Trailer Hitch Recommendation for a 2001 Isuzu Trooper
    The trailer hitch you referenced, # 65004, is a front mount hitch. If you need a replacement front mount we do not carry any options. But, if you need a rear mounted hitch, we do have several hitches that will fit your 2001 Isuzu Trooper. I have included a link to them for you. The most popular hitch for your vehicle is Curt trailer hitch # C13098. One benefit of this hitch is that the cross tube is sealed on both ends to prevent moisture from getting in and rusting the inside of the hitch. If...

  • Where Is Trailer Wiring Harness Connector On 1992 Isuzu Trooper
    The Curt trailer wiring harness, part # C55339 Is installed to the factory wiring harness connector located on the driver's side of the back of your 1992 Trooper. The connector should be attached to a grommet between the rear wheel well and the bumper on the exterior of the vehicle. It may also be near an exhaust pipe. With the vehicle is older it could be covered with dirt and tough to find.

  • Recommended Trailer Hitch Receiver For 2002 Isuzu Trooper To Install Yourself
    For your 2002 Isuzu Trooper, the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # 75043 is a confirmed fit. It is an easy bolt-on installation, so no welding is needed. It comes with the hardware needed. If you have a little mechanical ability, a couple sockets, and some jack stands or ramps you will be able to do the install yourself. For a slightly easier installation, I recommend going with the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" #...

  • Where Does a Trailer Wiring Harness Install on a 2001 Isuzu Tropper
    Trailer wiring harness # C55339 installs in a factory wiring harness located on the driver's side of the back of your 2001 Isuzu Trooper. The factory harness should be attached to a grommet between the rear wheel well and the bumper on the exterior of the vehicle. It appears that it also could be near or above an exhaust pipe. Since the vehicle is over 15 years old it is possible that the location is covered with road grime and/or is otherwise difficult to see. It may be easier to find...

  • Trailer Wiring Solution for 1994 Isuzu Trooper
    The trailer wiring kits that fit your 1994 Isuzu Trooper loike the # C55339 do not use T-connectors that tap into the taillight wiring like you were mentioning. This plugs into a port on the vehicle specifically for trailer wiring so you'd need to go with this kit instead of trying to rewire what you have. We also don't offer any of the OEM vehicle connectors either.

  • Does Trailer Wiring for 1994 Isuzu Trooper Install with One or Two Connections
    The trailer wiring harnesses like the Curt # C55339 that fit your 1994 Isuzu Trooper only install with one connection point. Some require you to plug them in behind both taillights on the vehicle but since your vehicle has a port for trailer wiring only the one connector is needed.
