  • Trailer Harness 7-Way to 4-Way Wiring Adapter for a 2002 Ford Explorer
  • I am not familiar with a 3 pin trailer connector. I am assuming you have a 4 pole (4 pin) that has 3 male and one female pins. If this is the case, you will need a 7 way to 4 way adapter, like part # PK12716.

  • Will Adapter PK12716 Work With a 2008 Chevy Pickup Towing a Boat Trailer
  • Yes, adapter PK12716 will fit your 2008 Chevrolet Pickup factory plug as long as it is a 7-way plug. It should look similar to part # PK11916. It would have no problem connecting to the 4-way flat plug on your boat trailer. However, I do recommend double checking the style of your trailer plug, as 5-way plugs are very common on boat trailers. If you have a 5-way plug, it would look similar to part # 20016. If you do happen to need a 7-way to 5-way adapter, you could use part # 37385,

  • 7-Way Balde to 4 Flat Adapter Compatible with a 2008 Mercedes M-Class GL 450
  • If your 2008 Mercedes 450 M GL model has a 7-Way connector, and your trailer uses a 4-Way flat, then the Pollak 7 Pole to 4 Pole Connector Adapter, # PK12716, will work. The unit plugs into the 7-Way socket on your vehicle and the 4-pole on the trailer plugs into the back of the adapter. We actually have many of this set up. I have included a link to them below. If you are not receiving any power or signals from your vehicle side connector, that could be the reason nothing has worked. You wil

  • Troubleshooting Trailer Lights Blinking Out of Sequence on Trailer Towed by 2007 Chevy Trailblazer
  • It could be a bad ground or a short. You will have to check the grounds on each of the trailer lights and on the trailer connector. The lights usually ground through the mounting studs. If there is any dirt, corrosion, or rust it could cause a bad connection. You will also want to check where the light bracket mounts to the trailer and the ground at the trailer coupler. I have included videos below on testing for a ground and testing for shorts.

  • How Do I Convert My 2006 Toyota Sequoias 7-Way Connector to a 4-Way Connector

  • Troubleshooting Left Turn Signal Problem When Using 7 to 4-Way Wiring Adapter PK12716 on a 2006 GMC
  • To determine where the problem is occurring, I would use a circuit tester to check for function at a couple different points. You will either need to leave on the turn signal in the cab of your truck, or have a helper operate it for you. We offer circuit tester # 3808 if needed. First, without the adapter or trailer connected, you can make sure that the left turn signal is reading correct at the 7-Way plug on your 2006 Sierra. The left turn signal is normally located at the second blade from

  • Adapter Needed to Convert 4-Pole Trailer Connector to 7-Way for 1997 Chevy Tahoe
  • We offer an adapter that will convert your existing 4-pole to a 7-way. Part # 37185 also features a 4-pole for smaller trailers. If your trailer has brakes and you want them to actuate, you will also need a brake controller installed on your Tahoe. I would recommend a proportional controller, like the Tekonsha Prodigy 2 part # 90885. A proportional controller is preferable to the older time-delayed controllers, because the proportional controller can sense how quickly and with how much int

  • Wiring Converter Needed to Connect a 3-Wire Motor Home to a 2-Wire Boat Trailer
  • Yes, since your motor home has separate brake and turn signals, and your boat trailer has combined brake and turn signals, you will need to use the Draw-Tite Taillight Converter, part # 119175KI.T To begin, you will need to access the wiring of your tail lights from inside the motor home. I would recommend having a friend help you operate the lights and turn signals as you use the included circuit tester to test the wires for function. You will connect the wires on the input side of the c
