• 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.

• Trailer Turn Signals and Brake Lights Not Working on a Boat Trailer
  If you are getting the correct signals from the truck side trailer connectors, then the problem is on the trailer. There could be a number of issues causing the problem. The easiest to check would be the trailer side connector. With the trailer connected, test the wires right behind the trailer side connector using a circuit tester like # PTW2993. If no signals are coming through, then you know the connector is bad and it will need to be replaced. While you are at the trailer side connector,...

• Trailer Running Lights Do Not Work When Connected to a Honda CR-V
  So it sounds like you are using an adapter like # 37185 or something similar. You need to make sure the adapter is grounded to the vehicle frame otherwise it will not work properly. It could also be a ground issue on the trailer.

• Troubleshooting Malfunctioning Turn Signals on Utility Trailer Towed by 2006 Chevy Silverado
  The first thing you will need to do is to test the 4-pole connector on the truck with a circuit tester like # PTW2993. This will tell you if the wiring problem exists on the truck or on the vehicle itself. The pins on the connector fed by the yellow and green wires should light up your tester when the right turn, left turn and brake lights are activated. If you do not get any signal on the right or left turn pins, you most likely have a blown fuse. Check the fuse box under the hood. If...

• Not All Trailer Lights Work on Pontoon Boat Trailer Towed by a 2005 Nissan Armada
  The first thing I recommend is to check the vehicle side trailer connector using a circuit tester like # PTW2979 if you need one. Have someone sit in the vehicle and run through the lighting functions while you test the trailer connector with the circuit tester. If not all the functions work, you may need some relays. On a 2005 Nissan Armada there are tow package wiring relays that allow the wiring to function. It very well could be that some of the relays are missing or bad on your Armada....

• Trailer Running Lights Do Not Work When Connected to a 2011 Ford F-150
  First, check to see if the running light circuit on the 7-Way on your 2011 Ford F-150 has power using a circuit tester such as # PTW2992. If it does not then there is likely a fuse blown or blown or missing relay. Use the owners manual to locate any fuses/relays related to the tow package wiring. If there is power on the truck side connector then plug in the adapter and make sure there is power on the outside of it. If there is not then the issue is with the adapter. If there is power...

• Parts Needed to Install a 7-Way in a 2008 Ford F-150
  You will need to start with a 4-way (if you do not have one). For that you would want the # 40185. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # 3035-p and the # 37185 and a brake controller. The brake output circuit is ran to the truck frame rail where you can easily complete it to the blue wire of the 37185. Check out the FAQ article I attached on this...

  Many trailers actually do not have reverse lights but if yours does, you will want to check the center pin on the 7-Way connector on your truck to see if it is working. Use a circuit tester like # 3808 if needed to test the pin. If this pin does not show power when the vehicle is in reverse, then you will need to route a wire to the reverse light circuit on the truck to get it to work. It is also possible that you will need to check the fuse on the truck related to the reverse light circuit...

• Right Turn Signal and Brake Light Not Working on a 2003 Boat Trailer
  This sounds like a classic bad ground problem. To make sure it is a problem on the trailer and not the vehicle, disconnect the trailer and test the trailer connector on the vehicle. Use a circuit tester like # PTW2993 if needed. Have someone sit in the vehicle and run through the functions. If everything is working on the vehicle connector then that would indicate an issue on the trailer, probably a bad ground.

• 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...
