Features to know about

Installs Fast Without Cutting Wires: Plug-In T-Connector

Running trailer wiring can be a headache if you have to splice into factory wires. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector makes it easy—it simply plugs in-line with the existing tail light harness along the frame rail. No cutting, no guessing, and no exposed wiring. Once connected, you get a clean 4-way plug ready for trailer lights.

Ready for Trailer Lighting Right Away: 4-Way Flat Connection

This harness gives you a standard 4-way flat connector that powers your trailer’s running lights, turn signals, and brake lights. It’s all you need to get trailer lighting up and running safely behind your vehicle.

Simple Upgrade Path: Works with 7-Way Conversion Kits

If you ever need more than just lights—like trailer brakes or 12V power—you can easily add that later. Start with this 4-way harness, then use a kit like the ETBC7 to convert it to a 7-way setup. That opens the door for installing a brake controller or charging a trailer battery without redoing your wiring.

Clean Fit Along the Frame Rail: Factory-Style Connection Point

The connection point sits inside the driver-side rear frame rail, protected from the elements and tucked out of sight. It plugs right into the factory harness for a solid fit and reliable signal transfer to your trailer. It’s a straightforward install that looks like it came from the factory once finished.

etrailer customer service gets eleven stars but Curt gets one star due to issues on their end.

Product was a perfect fit and works well. About the only improvment I can think of would be to provide an adapter for a 5 pin trailer connection.

  • Hardwiring a Brake Controller for a 1999 Chevy Tahoe
    Unfortunately, the 1999 Tahoe does not have the port under the dash to plug in the brake controller wiring adapter. You will need to hardwire your controller. We have a how to pagethat you might find helpful, I have linked to it below. There are wires ran from the above the spare tire to the engine compartment for the trailer brakes and the 12v trailer lead. Under the hood, these wires which are usually blue and orange, and are bundled with tape and located below the brake booster. You...

  • Trailer Hitches and Wiring for a 1993 Chevy 1500 Truck and 1999 Chevy Suburban
    You would not be able to move a trailer hitch back and forth between the 1999 Suburban and 1993 Chevy 1500 because the hitches are different between these vehicles and are not interchangeable. Also, you would have to get new hardware every time. The hardware is meant to only be torqued down once and not reused. For the 1999 Chevy Suburban the most popular hitch is # C14029. For the truck the most popular option (for models with standard or step bumper) is # C14081. The recommended ball...

  • Trailer Hitch for 1997 Chevrolet Tahoe
    Hey David! The Curt Trailer Hitch Receiver # C13029 you were looking at fits all models of the 97 Tahoe, including your 2-door 4WD. This has a bolt-on installation and comes with a limited lifetime warranty. Do you plan on towing? If so, you will also need Curt # C55319 for a 4-way. This will allow you to power your trailer's signal lights. For a ball mount, check out the etrailer # e67DR

  • 7-Way Wiring and Brake Controller for 1999 GMC Suburban
    Hi Lamont; if you already have a 4-way on your 1999 Suburban you can upgrade to a 7-way using the # ETBC7 you were looking at. If you don't have a 4-way, you will also need the Curt T-Connector Vehicle Wiring Harness # C55319. Once you have your wiring installed you will be able to add a brake controller like the Tekonsha Primus IQ # TK90160. This is a budget friendly option that still has a lot of nice features and is proportional. What kind of trailer will you be towing?

  • Brake Lights Not Working w/ the Pedal Pressed But Working w/ the Manual Override
    Hey Tiara! It sounds like the problem with your 1999 Chevy Tahoe is a bad brake controller switch. This is what sends the signals to your brakes to active the trailer lights. When you use the manual override, it bypasses the need for a brake signal on the vehicle and applies power to the trailer brakes. That is why it works when you hit that button. There's a wire that needs to attach to the stop light switch above the brake pedal. It connects to the wire on this switch that carries a...

  • Brake Controller Install Procedure for 1998 GMC/Chevy Suburban K2500
    GM didn't start prewiring the Suburban until the 2000 model year. To install a brake controller like the Tekonsha # TK90160 Primus, you'll need to hardwire the controller into place. As a starting point, you'll need to have a functional 4-pole trailer connector. The # C55319 would be the easiest way to install one. Once that's in place, you'll use our brake controller install kit, part # ETBC7. The kit includes the adapter that will convert the 4 pole provided by the # 118319 into a 7-way,...

  • Hitch, Brake Controller and Wiring for Towing with 1995 Chevrolet Suburban 4X4 K2500 7.4L
    We do not have a single kit/product with all the towing components you'll need to tow a trailer with brakes with your 1995 Chevrolet Suburban 4X4 K2500 with 7.4L engine but we can still get you all set. To wire a trailer brake controller such as the tried-and-true Prodigy P2 # 90885 in your Suburban you will need only a 4-pole wiring harness (either an existing factory one or you can use # C55319) and our Brake Controller Install Kit # ETBC7. This complete kit includes all the electrical...

  • Installing a 7-Way Trailer Connector On A 1998 Chevrolet Tahoe
    To replace your 7 blade plug, the colors of wire will vary sometimes even within the same model year vehicle. We will have to match function to function. I recommend using a circuit tester, like the Quickee Circuit Tester # PTW2993, to test the function of each wire and then connect it to the proper location on your new 7-way connector. I've attached a picture for you to assist in connecting the right function to the corresponding pin on your 7-way.

  • Installing New Trailer Wiring Connector on 1999 Chevy Tahoe
    The truck wire colors don't give me enough information to assist. You will need to test the wires for function. I recommend using a circuit tester like # PTW2993. It is possible that the 5th wire you see is for a reverse light function for a 5-way trailer connector, but you'd need to test to confirm. Your Tahoe should already have a factory trailer connector behind the bumper like you can see in the attached video for the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer...

  • How to Wire a Brake Controller on a 1999 Chevy Suburban K1500
    Your 1999 Chevrolet Suburban will need to be hard wired for installation of a brake controller. The Suburban did not get the wiring update that the pickup did until the 2000 model year, so the Universal Brake Control Wiring Adapter, item # 3025-S, will not work on your Suburban. You will need to splice the red wire from the back of the brake controller to the wire at the back of the brake pedal switch that carries power only when the brake pedal is pressed. You will also need to wire the...

  • Brake Controller Installation on 1998 Chevy Suburban
    GM did not start using the port under the dash until the 1999 model year. You will need to hardwire the controller into the existing vehicle wiring. Depending on what the tow package on your vehicle included, some of the wiring might be in place. Does the Suburban already have a trailer connector? If so, is it a 4-pole or a 7-Way? GM typically ran a blue and an orange wire from the rear of the vehicle up to the engine bay that terminates under the brake booster. In a 12 year old vehicle,...

  • How To Install a Brake Controller on a 1999 GMC Yukon
    When installing a brake controller such as the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 on your 1999 GMC Yukon you will want to run the power wire (black) from the brake controller to the battery not the fuse box. You will also want to use a 20 amp circuit breaker like part # PK54220PL in between the controller and battery. Place the circuit breaker 6" from the battery and run the remaining wire to the brake controller. You will also need both 4 and 7-way trailer connectors...

  • Hardwiring in a Trailer Brake Controller on a 1996 Chevy Suburban
    The 1996 Chevy Suburban does not have any tow package wires or a plug to plug in a brake controller. You will need to hardwire in the controller. If you just need the red wire for the brake input, then to find it you will need to use a circuit tester such as # PTW2993. You will probe the wires on the brake switch located above the brake pedal until you find the one that only has power when the brake pedal is pressed. If it has power with the headlights on or turn signals on then it is...

  • Will Trailer Hitch From 1999 Chevrolet Silverado Fit A 1999 Chevrolet Suburban
    The trailer hitch that came off the 1999 Silverado will not fit the 99 Suburban. The structure of the hitch and the mounting flange and holes are different. If you let me know the manufacturer and model of the hitch you bought I can find out what vehicles it will work with. If you need a trailer hitch for your Suburban I recommend part # C13402. This is a Class lll hitch and it has a 2-inch receiver opening. This will fit the new body style that has the amber turn signals. If you plan...

  • How to Install a Break Controller from Scratch on a 1996 Chevy Suburban
    To install the Tekonsha P2 Proportional Brake Controller, # 90885, on your 1996 Chevy Suburban, you will need a couple of items. First, the brake controller. Next, Tow Ready Custom Fit Vehicle Wiring, # C55319, if you do not already have one. Last, a 7- and 4-Way Installation Kit, # ETBC7. You will need to hardwire the brake controller, but it is not all that difficult for the average do-it-yourselfer. Start by installing the # C55319 harness. Installation is simple.

  • Recommended Trailer Hitch for a 1994 GMC Yukon
    Since you referenced 3 trailer hitches that fit your son's 1994 GMC Yukon I believe you are referring to the Curt options. The main difference between all 3 options is that each one has different gross towing weight (GTW) and tongue weight (TW) weight ratings: Curt Class III - # C13121 500 lbs TW/5,000 lbs GTW Curt Class III - # C13029 600 lbs TW/6,000 lbs GTW Curt Class IV - # C14029 1,000 lbs TW/10,000 lbs GTW When I looked up the max trailer weight rating for a '94 Yukon it looked...

  • Parts Needed to Install a Brake Controller in a 2000 Cadillac Escalade
    You will need to start with a 4-way (if you do not have one). For that you would want the # C55319. 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.

    GM did not start equipping their trucks with the plug-in connector until the 1999 model year Silverado/Sierra. In some of the mid to late 1990s models, GM provided what could best be called a rudimentary tow package, with a blue and a red or an orange wire ran from below the master cylinder, under the cab and along the drivers side frame rail to terminate on the frame rail behind the rear wheel. Because of the age of the vehicle, the ends of the wires are usually pretty hard to find, with...
