  • How Does P3 Brake Controller Install in 2007 GMC Yukon
  • On your 2007 GMC Yukon there actually isn't a brake controller install port under the dash that a connector will be able to plug into. Instead there are four blunt cut wires by the emergency brake pedal that you will need to wire the controller directly to. If you check out the install video link I attached on this page you can see how we installed the P3 on a similar Yukon for you to check out.

  • How Difficult is it to Install a Brake Controller for a 2008 GMC Yukon Denali
  • With a 2008 GMC Yukon, the install would be very simple for brake controller. GM includes a bundle of wires underneath the dash for a brake controller. One of our most popular brake controllers is the Tekonsha Prodigy, part # 90885. To wire the Prodigy you would match the wires as follows: Black on Prodigy to Red/Black on Yukon, White on Prodigy to White on Yukon, Red on Prodigy to Light Blue/White on Yukon, and Blue on Prodigy to Dark Blue on Yukon. There are two more wires in the engine...

  • Brake Controller Installation for a 1999 GMC Yukon
  • For your 1999 GMC Yukon to install a brake controller you will have to do a hard wire installation to connect your brake controller. Unfortunately there is not a quick connection port available on your year Yukon. If you already have a 4-way, you can then use the # ETBC7 to install a 7-way. If you need to establish a 4-way you can use # 189319. I have included some links to installing the # ETBC7, and the hardwired installation of a brake controller for your reference. If you don't...

  • Function Of Trailer Vents On Enclosed Trailer
  • The vents we offer for an enclosed trailer like part # 9139 are designed to allow air into the trailer. None of the vents we offer create a pressurized condition in the trailer and none are equipped with an air filtration system to keep dust out. Some of the features on the vents like # 9139 allow you to adjust the amount of airflow in the trailer with a butterfly valve mounted on the inside of the vent which would be operated from inside the trailer. Other trailer vents, like part #...

  • What Might Cause Trailer Battery to Die When Connected to Tow Vehicle
  • What all is connected to your trailer battery? You'll need to go through the list of all connections made to your trailer's battery so that you can determine what all could be drawing amperage and then make sure all of those accessories are turned off when you are towing. The 12 volt accessory pin of your 7-way can put a maintenance charge on your battery as well if needed. This is the pin in the 1:00 position on the vehicle 7-way. You'd want to run 10 gauge wire like part # 10-1-1 (sold...

  • Where is the Tow Package Wiring on a 2011 GMC Yukon to Install a Prodigy Trailer Brake Controller
  • On a 2011 GMC Yukon, there will only be bare tow package wires tucked up under the dash instead of a plug. Look below the steering column and to the left of the brake pedal for the wire bundle. The wires you need will be held together with a white tag that also tells you what each wire does. The tow package wiring should be as follows unless otherwise noted on that white tag: Red/black tow package wire connects to black brake controller wire. White connects to white. Light blue/white...

  • 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...

  • Installation Instructions for Front Mount Trailer Hitches for a 2004 GMC Yukon
  • If you are talking about Curt hitch # 31302, the instructions do not mention drilling at all.

I have linked the instructions to the right for reference.

  • Correct Brake Settings for Primus Brake Controller With 2014 GMC Yukon
  • There is no universal setting for the Primus # TK90160 brake controller. What you'll need to do is adjust the power initially by driving on a flat surface at 25 mph and turning the power up if the brakes are not effective and down of the brakes lock up. After that, the boost setting is generally higher the more the trailer weighs compared to the vehicle, though it will depend on things such as the condition of your trailer brakes and the manner in which you drive.

  • Installing Weight Distribution System on Vehicle with Auto-Leveling System
  • If you are able to turn off the Auto-Leveling system on your 2017 GMC Yukon XL, it is best to turn off the system when using weight distribution. This will ensure the system is installed correctly and is the ideal setup. If you are unable to turn off the auto-leveling, then I recommend the next best solution is connecting your trailer, letting the vehicle auto-level and then adding the spring bar tension to your system. At that point you will be able to determine if further adjustment...

  • Front Trailer Hitch for 2017 GMC Yukon
  • Though we have not had a chance to do a video showing the Curt Front Mount Hitch # C31073 being installed on a 2017 GMC Yukon, I have linked the installation instructions for you to take a look at. No drilling into your Yukon's frame is required to install this hitch and the only modification required is the removal or trimming of lower plastic air dam. You can carry a dirt bike with this hitch and a carrier such as the etrailer Motorcycle Carrier # e98873 so long as their combined weight...

  • Compatibility of Stromberg Carlson Bike Bunk with Trailer Front Fold-Out Camper Bunk
  • With the upper crosstube removed, the height of the Stromberg Carson Bike Bunk # CC-275 above the trailer frame will be reduced by the height of the tube, approximately 2-1/4 inches. This will still leave the arms of the Bike Bunk approximately 31-1/4 inches above the trailer frame. The best recommendation I can make is to remove the Bike Bunk # CC-275 from the trailer when you need to lower the camper's bunk. This will ensure the Bike Bunk will not contact the trailer.

  • The Putco Punch Stainless Steel Bumper Insert, # P84160, does fit in the lower opening that you are describing. This is an insert so it will not replace that plastic piece and the license plate mount will stay in the same place on the 2011 GMC Yukon XL. I have included a link to all of the grille options for your vehicle.

  • The wiring to power the brake controller on your 2011 GMC Yukon Denali is under the hood on the driver side next to the fender well. Remove the cover for the power distribution box and you will find the wire taped to a harness between the fender well and power distribution box.

  • How Does Kat's Circulating Tank Heater Install On 2001 GMC Yukon with 5.3 Liter Engine
  • I did some research and since the radiator hose of your 2001 GMC Yukon is 1-1/4 inch in diameter the correct hose adapter you'd need to use with the Kat's Heaters Thermostatically Controlled Circulating Tank Heater part # KH13200 is the part # KH28114. To install the heater you will first need to drain the cooling system. Then cut the lower radiator hose in the middle of the hose and install the 1-1/4" Lower Radiator Hose Connector for Kat's Heaters Circulating Tank Heaters part # KH28114...

  • How To Find the Right Brake Switch Wire to Install a Brake Controller on a 1999 GMC Yukon
  • If we ever have a 1999 GMC Yukon in to install a brake controller, rest assured that we will most definitely point out which is the brake switch wire to connect to. But in the meantime, I can tell you exactly how to find it. Like it says in the supporting documents for installation kit # ETBC7, you will need to use a circuit tester such as # PTW2993 to aid in finding the correct wire. You will probe the brake switch wires, located above the brake pedal, until you find the one that has...

  • Does Front Air Dam Need to Be Trimmed to Install Front Mount Trailer Hitch on a 1998 GMC Yukon 4x4
  • In order to install the Draw-Tite front mount trailer hitch, # 65005, the air deflector/fascia must be trimmed or removed on a 1998 GMC Yukon 4x4. I have included a link to the installation details for you. You will also need to determine if the front axle can handle the weight of a carrier and bikes. Keep in mind that your view will be limited with something mounted to the front and air flow will be reduced.

  • How To Install a Brake Controller on a 2007 GMC Yukon Denali
  • Half way through the 2007 model year, when they changed body styles, GM removed the brake controller ports from their pickups and none of their full size SUVs got it that year. Instead, they have a bundle of wires taped up under the dash that you can splice to. We have a really handy write up for these vehicles. That I have linked below. There will be 4 or 5 wires. If there are 5, you will not use one of them. You will match them up to the wires on the brake controller. Use the color...

  • Butt Connectors For 4-Way on 2003 GMC Yukon
  • Your 2003 GMC Yukon will not have a plug for a trailer connector unless it came with a factory 7-way. Since you are using a splice-in 4-way, that would indicate you do not have a plug. As for how you can rewire your current 4-way, you need to identify the turn and tail lights on your Yukon using a circuit tester like the Cordless Circuit Tester # PTW2979. Then just remove the quick splices and use Deka Heat Shrink Butt Connectors # DW05744-5.
