Features to know about

Installs Fast with a Single Plug: Factory Connector Fit

This harness keeps things simple by plugging directly into the vehicle’s factory trailer wiring port. There’s only one connection point, so you don’t have to chase down multiple plugs or tap into taillight wires. Just locate the factory connector near the rear driver’s side and plug it in. It’s ready to go without any wire cutting or splicing.

Clean Routing Through Existing Grommet: No Drilling Required

The harness connects through the existing rubber grommet at the back of the vehicle, making for a clean, protected install. You won’t have to drill new holes or run wires through exposed areas. The design uses what’s already built into the vehicle for a factory-style finish that looks neat and stays out of the way.

Reliable Converter Module: Consistent Signal Output

Built with an integrated converter module, this 4-way harness combines the stop and turn signals for trailers that use a single light system. The solid-state module helps keep trailer lighting signals consistent and protects the vehicle wiring from shorts or overloads. If your right or left signal ever stops working, it’s easy to test at the module using a standard test light.

4-Flat Trailer Connection: Ready for Basic Lighting Functions

The 4-flat connector provides all the essentials—running lights, left and right turn signals, and brake lights—for hooking up small or mid-size trailers. It’s the common plug style found on most light-duty trailers, so once you’ve got it installed, you can hitch up and get on the road with confidence that your lights will work every time.

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!

  • 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...

  • 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...

  • 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.

  • 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.

  • Brake Controller Recommendation for 1998 Isuzu Trooper Towing Camper Trailer
    The brake controller I recommend for you is the Tekonsha Prodigy P2 Trailer Brake Controller # 90885. This brake controller works to apply the trailer's brakes proportionally to the brakes of your 1998 Isuzu Trooper, helping the trailer brake smoother and causing less wear and tear on both the trailer and your vehicle. The P2 also features a digital display, 3 boost levels, battery protection, and continuous diagnostics. This controller is designed to work with trailers that have up to...

  • 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.

  • Troubleshooting Right Trailer Brake Light Not Working When Connected to 1999 Isuzu Trooper
    If the issue is on the vehicle side of your 1999 Izuzu Trooper this will likely mean the converter module which combines the wiring itself is damaged and needs replaced. We do have the Curt 4-Way # C55339 which plugs into a factory connector and only has a single brake light input. This tells me the internal portion of the module is failing to sent power to the right brake light if your right turn signal and left brake lights are functioning correctly as you said. You can always use a...

  • 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...

  • 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...
