• Cleaning OEM Tow Package Port for Curt 4-Way T-Connector on 2002 Ford F-250
  Based on what you have sent, it is highly unlikely this connector will still work. For your OEM tow package port the best thing I could suggest would be trying to use some electrical contact cleaner. You may want to start by using a small diameter brush or toothpick and attempt to scrape away the heavy dirt and debris or try wiping it with a dry cloth. After this is done, try using the cleaner and the brush. You could use a circuit tester like the # PTW2993 Hook Probe Circuit Tester to...

• Wiring Harness with Square Connector for 2004 Ford F-250 Super Duty
  Thank you for the photo of your Ford F-250's trailer wiring that has a square OEM connector o one end and both 4-pole and U.S. Car (round) connectors on the other end. We do not have this exact part (it may be OEM) but we do have wiring items with that square connector, such as 7-way # 40167 and 4-poles # C55265. These could be piggy-backed together to give you both connectors active at once. If you prefer you could use # 40167 and splice in a 4-pole like # C58044.

• Trailer Wiring Harness For 2004 Ford F-350 Super Duty With Square Connection Points
  What you are explaining is very common. It sounds like your 2004 Ford F-350 Super Duty pickup truck is equipped with a factory 4-way connection that can be replaced with Curt T-Connector Vehicle Wiring Harness for Factory Tow Package part # C55265 with square connection points. If you need to upgrade your 4-way to a 7-way plug the kit part # ETBC7 is needed because there is not a plug and play 7-way option with a square connector. The kit comes with all of the compenents needed to install...

• 2007 Ford Edge Correct Trailer Wiring Harness
  The Curt T-Connector Vehicle Wiring Harness # C56329 tees in behind the tail lights on your 2007 Ford Edge and then pulls power directly from your vehicle battery (via the included lead) so you don't overdraw the circuits on your vehicle when you have a trailer hooked up. The Curt T-Connector # C55265 you referenced is only confirmed to fit a 2002 - 2004 Ford F-250/F-350 with a factory 4-Flat connector. It has never been confirmed to fit a Ford Edge so if you decided to still go with this...

• Recommended 7-Pole Wiring Harness for 2004 Ford F-350 with Factory Tow Package
  I do have a wiring solution for you, but the Curt T-Connector Vehicle Wiring Harness # C55243 you referenced is not compatible with your truck. It is designed for certain models of 1999-2001 Ford Super Duty trucks. For your 2004 Ford F-350, you can use the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # C55774, as long as your vehicle is equipped with a factory 7-way connector. If your F-350 is equipped with a factory 4-flat instead, you can use Curt T-Connector # C55265...

• Adding a 4- and 7-Way Trailer Connector on a 2004 Ford F-350
  In order to install a 4- and 7-Way on your 2004 Ford F-350 you will first need to install # C55265. This will plug right into the port in the picture you sent. It does look like there are some loose wires there that you will need to hardwire to a 7-Way. For a 4/7-Way I recommend # 37185. the 4-Way will plug into it and then you will need to hardwire the remaining wires. White is ground and should attach to the truck frame. Blue is output to electric brakes. Black is 12 volt power. Purple...

• Wiring Harness for 2003 Ford F-350 Super Duty with Plug at Spare Tire Location
  The plug you have by your spare tire is the correct wiring harness for you to add a 4-way like # C55265. Your truck shouldn't require any any extra fuses or relays. For a 7-way you should be able to use the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness with 7-Pole Plug # 40167 which would also allow you to add that before mentioned 4-way as well. The Ford Replacement OEM Tow Package Wiring Harness, 7-Way # 118242 you asked from was only for light duty trucks but it does...

• Recommended Wiring Harness for 7-Way on 2004 Ford F-250
  I reached out to Curt and they said they do not have anything like that to fit anything past 2001 due to wire patents. So to get your 7-way, you will need to first get your 4-way connector. If you have the factory 4 way option, then you can use # C55265. If you don't have the factory wiring harness you will need # 18252. Once you have the 4-way flat, you can then use # ETBC7 to get the wiring connections, and circuit breakers for 7-way connection. If you want to add a brake controller...

• Troubleshooting Trailer Light Functions After Trailer Connection Pulled Apart
  It sounds like you have the factory wiring harness, but the # 118243 is not a fit for your vehicle. It is only a fit for 1999 to 2001 models. You would need either the Hopkins Plug-In Simple Wiring Harness # HM40165 or Curt # C55265. If you test your factory wiring connection with a circuit tester like # PTW2993 prior to connecting a harness, you will be able to determine if the issue is the harness or prior to the harness. If you are only having connection issues on the trailer side,...
