• Troubleshooting Brake Lights and Turn Signals Not Working on Trailer when Using Adapter # 47549
  
• It could be that the converter is wired differently than what your trailer is set up for. What I recommend is inserting the adapter into the trucks 7-Way and then use a circuit tester, like Quickee # 3808, to test the pins on the out going side of the adapter. Have someone sit in the truck and run through all of the functions, turn signals, brake lights, and running lights, while you test the pins. Compare the pin function/location with how the trailer is wired to determine if you need to d

• Recommendation for a 4-Way Flat to 5-Way Flat Trailer Connector Adapter
  
• The Lexus 300 and Nissan Pathfinder use different wiring harnesses, but if they both have 4-Way flat trailer connectors, they will be pinned the same (function the same). The 5-Way trailer side connector will have an extra function at the pin furthest from the covered ground pin. This function is typically used on surge couplers that have an electric lockout feature. The corresponding pin on the vehicle side would need to be connected to the reverse light circuit for this feature to function. Th

• Reverse Lights on Dodge Ram 2500 Series Stay On When Trailer is Connected
  
• The circuit that provides power to the reverse lights should be wired to the center pin on the 7-way trailer connector on your vehicle. It sounds as if you will need to do some troubleshooting to determine the cause of your problem. Check the plug on your trailer for corrosion or damage. If you find any green or white corrosion in any of the sockets on the connector, there is a good chance that the corrosion has spread to the interior of the connector, causing a short or feedback back into th

• Trailer Brake Lights Not Working on a 5th Wheel Trailer
  
• What it could be is the tow package fuse or relay for the brake lights is blown or otherwise not working properly. You will need to check the vehicle owners manual and/or check the power distribution box lid to find the tow package fuses/relays in question. Add or replace the offending part and test it again. If that was the problem and it blows again then there is a short somewhere, most likely a bad ground which could be where the two connectors come together or at the trailer tail lights.

• Troubleshooting Right Side Turn Signal Not Working On Trailer
  
• This sounds like a ground problem on the right side. The turn signal not working makes sense because with the brake lights, there is a constant signal coming through which is enough to make the lights illuminate on both sides like they should. But the on/off of a turn signal does not offer enough consistent voltage and makes the problem apparent. On the vehicle, check to see if there is a turn signal fuse for the tow package wiring that may have blown. You can use your owners manual to find

• How Do I Convert my 4-Way to a 6-Way Round on a Toyota Tacoma

• Installation of 6-Way Round on Camper to 7-Way Blade on 2009 Chevrolet Silverado
  
• There are two accepted ways of wiring a 6-way round connector. One uses the center pin as the 12-volt power accessory feed, the other uses the center pin for the brake output circuit (reverse lights). The Hopkins 7 Pole to 6 Pole Adapter, part # 47549, that you have referenced comes with the center pin wired up as the 12-volt lead, but it can easily be taken apart and rewired for the center pin to be for the reverse light circuit.

• Adding a Brake Controller to a 1996 Ford Ranger
  
• First, if your 1996 Ford Ranger came with a factory 4-Way trailer connector or you installed an aftermarket 4-Way, you will need to add an # ETBC7, if the trailer has a 7-Way blade style connector, or an # ETBC6, if the trailer has 6 pole connector. If you need to add a 4-Way, you would use # 118325. If you add a trailer connector or it already has one, the signals for the tail lights on the trailer are already converted down to the correct signals. In order to operate the electric brakes on

• Trailer Brakes Lock Up When Using Hopkins 7 Pole To 6 Pole Adapter # 47549 on 2001 Dodge Truck
  
• There are two accepted ways of wiring a 6-way connector. One uses the center pin as the 12-volt power accessory feed, the other uses the center pin for the brake output circuit. It sounds as if your vehicle and adapter are wired differently, locking up the brakes as soon as the trailer is plugged in. The Hopkins 7 Pole To 6 Pole Adapter, part # 47549, that you have referenced will allow the center pin to be wired as a 12V lead or a brake lead, whichever is needed to match your trailer. It com

• What is the Correct Trailer Wiring for a 2000 Lexus ES 300
  
• The only trailer wiring harness that is available for a 2000 Lexus ES 300 is # 119176KIT. This is a hardwire kit and a powered converter that requires a direct connection to the vehicle battery. This powered converter provides the power for the trailer lights and protects the vehicles sensitive wiring. I have included a link to the installation details and a link to a video showing a typical installation. I have also included a link to an FAQ with tips on connecting the power wire to the vehi

• Trailer Brakes First Locked Up and Now Will Not Work After Re-Wiring 6-Way Round Trailer Connector
  
• There are 2 ways to wire a 6-Way connector. The center pin will either be for the trailer brakes or will be the 12 volt power. When these are switched that is when you see the brakes engaging constantly. I have included a picture that shows the typical ways that a 6-Way is wired. The diagram shows the center pin with 12 volt power. If you configure the adapter correctly to match the trailer and the brakes are still not working then you will want to do some troubleshooting by first disconnecti

• Brake Lights On Trailer Do Not Work When Connected to 2004 Winnebago Ultimate Freedom 40KD
  
• Since your Winnebago already has a 6-Way trailer connector, the signals from the tail lights should already be converted down to a combined system. This means that on the 6-Way the left turn/brake lights are on one circuit and the right turn and brake lights are on one circuit. If you test the 6-Way and you get brake lights and turn signals correct pin locations then it is working correctly and the issue would be on the trailer side. If the brake signal is not coming through when testing the

• Replacing 6-Way on Trailer With 7-Way Connector
  
• Since wire color codes are NOT universal, we always recommend wiring by function, rather than wire color. If you look at the Trailer Wiring FAQ article I have linked you to, you can see some diagrams showing the proper way to wire a vehicle and trailer side 7-way trailer connector. If can you open up the existing 6-way connector on your trailer, take the housing apart and look at the terminals the wires attach to. In many cases, they will be labeled like what is shown in the FAQ article. Y

• Troubleshooting Trailer Brake and Turn Signal Lights on Car Trailer Towed by Jeep
  
• Thank you for providing the photo of your Jeep trailer wiring. We can suggest troubleshooting steps to isolate the problem to either your Jeep wiring, connectors or trailer wiring. First, securely attach the short white ground wire with ring terminal from the 7-way adapter to a clean bare metal surface on the Jeep frame. (Your photo shows this wire is not connected. This could be the problem.) You need to firmly attach all grounds to rust-free unpainted metal surfaces to ensure a good connect

• Testing the Center Pin On a 6-Way Trailer Connector
  
• You will need to use a circuit tester, item # 3808 if needed, to test the pins in the 6-Way connector at the rear of your vehicle. Ground the alligator clip to the vehicle chassis and touch the test light to the center pin. If the light in the tester lights then the center pin is hot, 12 volts. If the center pin is for brakes it will only have power when the brake pedal is applied or when the manual brake lever on the brake controller is activated. In most cases, the center pin in the 6-Wa
