• Trailer Brake and Turn Signals Not Working When 7-Way Connector Plugged into 2011 Ford F-150
  I would recommend checking the fuse box in your friends F-150 to make sure it has the fuses/relays installed for the trailer stop and turn lights. I looked up a fuse box diagram for a 2011 F-150 and it looked like the trailer tow left stop/turn relay is at location 37 and the trailer tow right stop/turn relay is at location 38. You will want to check the legend in the fuse box of your friend's vehicle to make sure those are the correct locations. I would also recommend using a circuit...

• Blown Fuse & Relay with New Utility Trailer Running Lights
  One possibility is that the running lights on the new trailer are simply drawing too much current and are blowing the fuses. Trailers can be equipped with either high-efficiency LED lights or standard incandescent bulbs, which draw about 10 times the power. If the new trailer has many more running lights than the boat trailer, and/or if they are incandescent types, then they may be overloading the vehicle wiring. It is also possible that the running light wiring is pinched, has a bare...

• Towing Capacities, Trailer Hitch and Wiring for 2005 Ford F-150 SuperCab 4WD With 5.4L V8
  According to Ford, a 2005 Ford F-150 SuperCab with four-wheel drive and a 5.4L V8 will have a capacity between 7,300 lbs and 9,300 lbs depending on what wheelbase it has and what axle ratio it has. I recommend finding what yours is and looking in your owner's manual, which will have these capacities. Then for a trailer hitch you can add the Curt Trailer Hitch Receiver # C14357 for a heavy duty, Class IV hitch and if you need to add a wiring harness the Plug-N-Tow (R) Vehicle Wiring Harness...

• Hitch Recommendation for 2005 Ford F-150 Long Bed
  The Draw-Tite Class III 2 Inch Hitch, part # 41549, that you have referenced will fit your 2005 Ford F-150 long bed. This hitch has a gross towing weight capacity of 6,000 lbs and a tongue weight capacity of 600 lbs. I am including a link to the installation instructions on the Draw-Tite hitch. The # 51020 hitch is listed as a Pro Series hitch that fits 1997 to 2004 Ford F-150, so it is not designed for your 2005 vehicle. If you will be towing with this hitch I would also recommend the...

• Installing a 7-Way on a 2006 Ford F-150
  I do have a solution for you to install a 7-Way connector on your 2006 Ford F-150 but, as you stated, both the Tekonsha # 118247 and the # 118242 are not compatible. If you have the US Car Connector at the rear of your F-150 then you can simply install the Reese # 74682. If, however, you do not already have a 7-Way that you are trying to replace you will need to install the Hopkins Plug-N-Tow # 40185 as well as the Universal Wiring Kit # ETBC7. The # ETBC7 will plug into the Hopkins...

  You may have a bad relay in your 2012 Ford F-150. Under the hood in the power distribution box check the relay in location 37. The easiest way to see if a relay is bad is to use a known good one in its place. You may have to get this relay from a Ford dealer.

• Troubleshooting Trailer Stop and Turn Lights
  On a 4-pole trailer connector like # 40185 brake and turn lights are carried on the same wire; yellow for the left brake and left turn light and green for the right brake and right turn light. Running lights for both sides of the trailer are carried on the brown wire. Since you tested your truck connector with a circuit tester like # PTW2993 and found that the correct signals are present on the pins for the yellow and green wires when you activate the brake and turn light functions, this...

• Troubleshooting Wiring Issues with 2008 Ford F-150 with Factory Tow Package
  If all your connections are bad, you may just have a bad connector and need the replacement # HM40975 and a few fuses. If you've already used a circuit tester like # PTW2993 to check the wiring functions individually and the fuses outlined in your owners manual, then you can Plug-N-Tow Vehicle Wiring Harness # 40185 or if those plugs aren't working either the hardwire # 18252.

• Troubleshooting Left Turn Signal Not Functioning on Trailer Wiring of 2014 Volkswagen Tiguan
  First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # 3808 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are clean and...

  The Tow Package Vehicle Wiring Harness with 7-Way Trailer Connector for the 2004 F-150, item # 118247, will not work on the 2005 model year Ford F-150. There was a were changes for the 2005 model year and the wiring package was changed on the Ford Trucks. To wire your vehicle for a 7-way connector you will need a 4-way connector first.

• Installing a Trailer Wiring Harness on a 2007 Ford F-150 with No Factory Connector
  The 2007 Ford F-150 either came equipped, from the factory, with a 7-way trailer connector or none at all. Since you don't have a trailer connector at all on yours you'll need to start by adding a 4-way connector like the Hopkins Plug-N-Tow, part # 40185. It plugs right into the truck's wiring behind the rear bumper. If the trailer you'll be towing has brakes, or you just want the 7-way to be fully functioning, you can then use our adapter kit, part # ETBC7, to convert the 4-way to a...

• What to Test When There is no Power to a Vehicles 7 Way or 4 Flat
  The fuses are typically the place I start when troubleshooting a plug with no power, but as you have completely replaced your fuse box, that is a bit of a moot point. What is most likely causing the lack of power is damage to one or more wires. Using a tester, like the Circuit Tester # PTW2993, you will need to test the pins on the plug. If you have a 7 Way connection, the 2 o'clock position will be your 12-volt power, the 3 o'clock position will be the right turn signal and right brake...

• Troubleshooting Truck Blinkers that Only Blink Once when Trailer is Connected
  If I am understanding you correctly it sounds like when your trailer is connected to your truck and you activate either blinker your truck's blinker only blinks once then stops. This would lead me to believe that your blinker circuit is getting overdrawn by the trailer circuits which is preventing them from working. What I would recommend you do is replace your current trailer blinkers with LED blinkers as they will draw considerably less power than incandescent bulbs which should prevent...

• Trailer Turn Signals and Brake Lights Stopped Working with 2005 Ford F-150
  The first thing to check is the trailer connector on your 2005 Ford F-150. With the trailer disconnected use a circuit tester such as # PTW2993 to test the vehicle side connector while someone sits in the cab of the truck and activates the turn signals and brake lights. If there is power at the truck side connector, then the problem is on the trailer. Make sure that the truck and trailer side connectors are clean and free of corrosion inside where the wires attach and outside on the pins....

• Trailer Lights Stop Working and Blinker Flashes when Connected to a 2007 Dodge Charger
  There are a few things that you can check to determine what the problem may be on your 2007 Dodge Charger. First check the connectors for the harness and where they connect to the vehicle. You may find a bent terminal that you can put back into place. If the trailer has a lot of extra lights then it could be overloading the harness and the electrical system on your 2007 Dodge Charger. The system is rated for a maximum of 1 stop/turn light per side (7.5 amps), and a maximum of tail light...

• Ford F150 Trailer Wiring Harness for a Trailer with Surge Brakes
  If you do not have a working four way on your 2008 Ford F150 then you can use the item you selected, # 30185, for the four-way connector. If you have a working 4-way connector you will not need the part # 40185 wiring harness. In either case you will need to wire a 7-way connector from the four-way connector. We have adapters for this purpose, part # V30606 or part # 30717. With these adapters you will plug the 4-way from your truck to the 4-way on the back of the adapter and then hard...

• Comparing Class III and Class IV Trailer Hitches for a 2008 Ford F-150
  There are going to be several differences between a Class III trailer hitch and a Class IV trailer hitch like Draw-Tite Trailer Hitch, # 41933. One difference is how each attaches to the truck. The Class IV hitch requires more attachment points. I have included a link to the installation details for this hitch below that better illustrates where and how the hitch attaches to the truck.

• Troubleshooting 2013 Ford F-150 Trailer Wiring that Blinkers Stopped Working
  Sounds like you may have some blown fuses under the hood of your 2013 Ford F-150. Check the fuse box for trailer wiring fuse locations and replace as necessary as it sounds like the turn signal circuit fuses have blown. This circuit most likely blew from a short circuit on your trailer wiring. Before you reconnect your trailer wiring I would check the wiring for the turn signals and fix any cut or exposed wire on the circuit that could be causing the short.

• Replacing Factory 4-Way on 2006 Ford F-150 with 4-Way/7-Way Connector
  Yes! The Hopkins Plug-N-Tow # 40185 is a plug and play solution for replacing the factory 4-Way on your 2006 Ford F-150. To add a 7-Way/4-Way connector you would then need the Hopkins # 37185.
