2000 GMC Yukon - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

  • 4 Flat
  • Trailer Hitch Wiring
  • CURT
  • No Converter

Quickly and easily install a 4-way trailer connector on your GMC Yukon with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind rear bumper
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


Installation

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


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.

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.

  • How To Tow With The 1994 Chevrolet Suburban
    The best place to get the best information of towing capacities and limitations is in your owner's manual. According to my research the towing capacity of your Suburban hitch has a towing capacity of around 10,000lbs. Please confirm this with your manual and GM before towing. Subtract GCWR from GVWR to determine towing capacity. In regards to the concerns about the transmission, I am going to recommend a transmission cooler to keep it cool while trailer towing. Since your Suburban is already...

  • What is Needed to Install a Brake Controller in a 1999 GMC Yukon
    There is not a place under your dash for you to plug in a brake controller. You will need to use a brake controller 7-Way installation kit, part # ETBC7, in your 1999 GMC Yukon to hard wire and install a brake controller. I attached installation instructions and an installation video for this product for you to check out also. If you do not have a 4-Way present at the rear of your vehicle, you will need one before you can install the # ETBC7. I would recommend a custom fit wiring # C55319....

  • 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,...

  • 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...

  • Will Draw-Tite Hitch Part 41511 Fit 1999 2 Door 4-Wheel Drive Chevrolet Tahoe Full Size
    I called our representative at Draw-Tite, and he informed me that Full-Size is used to differentiate from the smaller or mid-size Blazer model. If you have the bigger model Tahoe, or the full-size Tahoe, then yes, the Draw-Tite Class III Max-E-Loader Trailer Hitch Receiver, part # 41511, will fit your 1999 2 door 4 wheel-drive Chevrolet Tahoe. In addition to part # 41511, you may need the following, to complete your towing setup: Hitch ball part # 19247, or part # 19260 Ball mount...

  • Recommended Trailer Brake Controller for 1994 Chevrolet Suburban Towing 2002 Airstream Safari
    You are absolutely right that there are seemingly endless options in a trailer brake controller, but the ones that are simplest to install, that work best and that have proven their long-term reliability are fewer in number. I suggest you use one of the Tekonsha Prodigy proportional-type brake controllers that slow the trailer right along with the Suburban's rate of deceleration. These deliver smoother braking performance than time-delay type controllers. The linked brake controller article...

  • How to Install The Primus IQ Brake Controller on a 1998-1999 Chevrolet Tahoe Classic
    Installation of a brake controller on your 1998-1999 Chevrolet Tahoe Classic is pretty straight forward. You will need several items to complete the install. First, you will need a working 4-Way connector, item # C55319, if you do not already have one. I have linked installation instructions for you to review. Once you have a working 4-Way connector you will need a Brake Controller 7 & 4 Way Installation Kit, item # ETBC7, to complete the wiring from the back of the vehicle, to the brake...

  • Do You have a Brake Controller Wiring Diagram For a 1998 Chev. Tahoe,7 way-Brake Controller
    To wire your 1998 Chevrolet Tahoe for a 7-way connector and a brake controller you will need a 4 way wiring harness for your vehicle, part number # C55319 and a Brake Controller 7 & 4 Way Installation Kit, part number # ETBC7, along with the # 90195 brake controller you selected. You will attach the 4-way wiring harness inline with the connector located on the inside left rear frame rail. Then you will connect this 4-way to the 7-way kit to power the taillight functions. After this is done...

  • Recommended Trailer Hitch For 1998 Chevrolet Suburban Towing Small Fleetwood Travel Trailer
    We have a couple of trailer hitches that are designed to fit your 1998 Suburban. I recommend the Curt Trailer Hitch, part # C13029. This is a class lll hitch and it also has a 2-inch receiver opening. We also have the Class lV Curt hitch, part # C14029. This hitch has a higher towing capacity and tongue weight capacity but since you said it is a small trailer it may be overkill. This trailer hitch has a 2-inch receiver opening. I recommend these two hitches because no drilling is...

  • Will the Curt Trailer Hitch C14029 Allow Rear Spare to Be Stored Under Truck
    The Curt hitch part # C14029 that you referenced has been confirmed as a fit for your 1998 Chevy Tahoe and would allow you still fit your rear spare tire under the rear of your vehicle. I attached an install video for this hitch for you to check out as well. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8...

  • 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. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake...

  • Parts Needed to Install Prodigy P2 Brake Controller 90885 in 1998 Chevrolet Suburban
    Your 1998 Chevrolet Suburban does not have an under-dash brake controller port like your F-150 did so to install your Prodigy P2 # 90885 in the Suburban you'll just use our brake controller installation kit # ETBC7 to hard-wire it. You need to have a working 4-pole harness on the vehicle to do this; if you need a 4-pole flat harness you can use # C55319 which is a plug-and-play part. The linked video shows the ETBC7 being installed in a 1999 Suburban and a helpful article is included too.

  • 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...

  • Brake Controller for 1999 Chevy Tahoe Towing a 2006 Fleetwood Bayside Camper with Electric Brakes
    Since brake controllers are not vehicle-specific, you can use any of our brake controllers with your 1999 Chevy Tahoe and camper. The Dexter Axle Predator Electric Brake Controller, part # 58-8, is a great choice. It is inertia-activated, meaning you have a lot of mounting options for inside your Tahoe, has an LED display showing voltage output, and works with 1 or 2 axles. If you don't already have a 4-way connector on the back of your vehicle, you will need the custom-fit Vehicle Wiring...

  • How to Install a Brake Controller on a 1999 GMC Suburban
    Your 1999 GMC Suburban does not have a port under the dash to connect a brake controller harness. You will need to hardwire the Hopkins Agility Brake Controller # HM47294 with brake controller 7 and 4-way installation kit, item # ETBC7, or a 6 and 4-way installation kit, item # ETBC6, depending on the connector you need for your trailer. These kits come with everything needed to install the brake controller and wiring from scratch as long as you have a 4-way connector installed on your...

  • Procedure and Parts Needed for Brake Controller Install on 1995 Chevy Tahoe
    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...

We also have a video that walks you step-by-step through how to install it. If you will be towing a trailer that has a 7-pole or 6-pole plug, we have kits that make upgrading a breeze.

  • Location to Connect 4-Way on 1994 Chevy Blazer
    According to a pair of manufacturers I checked with, your 1994 Chevy Blazer will have a t-connector beneath your Blazer along the driver's-side frame rail. So long as your '94 Blazer is a full-size, this will allow you to use the Hopkins Plug-In Simple Vehicle Wiring Harness # 41125 or Curt T-One Vehicle Wiring Harness # C55319. Your Blazer must be a full-size though; if it is not there isn't a wiring harness available.

  • Brake Controller Recommendation and Installation on 1993 Chevy Suburban and 2014 Ram 1500
    Unless you actually need a separate controller for both vehicles because they'll be used for towing at the same time, I'd purchase one controller and swap it back and forth between the two vehicles as needed. I'd love to sell you two controllers, but not if you only really need one. For a controller, I'd recommend either the Tekonsha Prodigy P2, part # 90885 or the P3, part # 90195. Functionally speaking, the two are pretty similar, but the P3 has a more user-friendly display that would...

  • 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...

  • Recommendation for a Brake Controller on a 1999 Chevrolet Tahoe and Installation Instructions
    Between the Tekonsha Prodigy P2 Brake Controller, item # 90885, and the Tekonsha P-3 Trailer Brake Controller, item # 90195, I would recommend the P2 if you are going to be towing mostly one trailer that does not have a wide range of loads on it at different times, like a travel trailer. Both the P2 and P3 brake controllers are excellent options, the only reason I do not recommend the P3 is that the it is more complicated to setup and operate because of all of the extra functions it has....

Apart from the controller itself this contains all the parts you need to fully a wire a controller like the superb Prodigy P3 # 90195.

  • 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.
