  • Diagram for a Vehicle Side 7-Way Trailer Connector on a 1999 GMC Yukon Denali
  • We do have a diagram of the typical 7-Way pin-out that will be on your 1999 GMC Yukon Denali. I have included a picture for you and a link to a wiring FAQ that will be helpful.

  • To determine the towing capacities of the 1999 GMC Yukon and if they change with the use of weight distribution, you will need to look at the owners manual in the towing section.

  • Installing a Trailer Brake Controller on a 1999 GMC Yukon Denali
  • A simple plug in location for a brake controller is not available on the 1999 GMC Yukon. You will need to hardwire in the controller.

  • Can Electric Trailer Brakes be Used in Salt Water when Adding a Weight Distribution System
  • There are several options for using a weight distribution hitch with your boat trailer and keeping the brakes working properly. If you want to go to electric brakes you can, but you will need to be sure to rinse the brakes with clear water each time you use the boat in salt water conditions. I normally do not recommend electric brakes in wet conditions but it can be done. Electric brakes will corrode much faster and are not available with galvanized parts like hydraulic drum brakes are.

  • Which Stromberg Carlson Bumper Mounted Tire Carrier Should I Use, # TR-1 or TR-2
  • The only difference from the Bumper Mounted Tire Carrier, part # TR-1, and part # TR-2, is that part # TR-2 folds down to provide access to storage areas when mounted to your RV. If you think the folding feature would come in handy, I would recommend part # TR-2. If you think you can do without the folding feature, part TR-1 will work just fine. Part # TR-1 may also be a little quieter when mounted, as it is all one piece. I contacted our representative at Stromberg Carlson about what siz
