Do you have a question about this Wiring?

• Trailer Wiring Harness is Funtional Except Trailer Brakes
  
• Since every other function works, my guess is the brake magnet wires have a problem. One wire from each assembly magnet should be wired to the brake controller wire. The other should be grounded. Since they work when you provide an alternate ground via the tester, I assume the ground is the problem. The first thing I would do is check these grounds. The closer the ground connection is the the brake assembly the better. There may be a break or a pinch on the brake wire going from the trailer c

• 7-Way Blade to 7-Pin Adapter for Towing a Trailer with A 7-Pin Connector
  
• The wiring for the 7-Pin connector is different than the 7-Way blade connector. You will need an adapter to make the two different styles compatible. You can use the Adapter 7 Way (Blade) to 7 Way (Round Pin), # 47595. The blade end plugs into the 7-Way on your vehicle and the trailer round pin 7-Way will plug into the receptacle. I have also included a link to a wiring FAQ article that shows how the two styles differ from one another.

• Parts Needed To Wire 7-Way Round to 7-Way Flat Connector
  
• You could use the 7-Way Adapter, part # 47595, if your vehicle uses a 7-Way blade connector and your trailer has a 7-Way round. The other option would be to just change the trailer and vehicle connectors to a 7-way Blade Connector to avoid using an adapter. For a replacement 7-Way blade, trailer side connector, we have the Pollak 7-Way RV Style Trailer Connector, part # PK12706. You will need to match up the wiring functions for each pin to install the 7-way on your trailer (see FAQ). If y

• Testing a Trailer and Vehicle for Wiring Problems When Trailer Lights and Brakes Do Not Work
  
• First, you will want to make sure that your towing vehicle and the trailer have connectors that are compatible. I have included a link to our wiring FAQ that covers what the functions should be on various connectors. Use a circuit tester like # 3808 if needed to test the pins on the towing vehicle. Then you will need to determine if the trailer side connector is wired the same way by tracing the wires back from the connector. You will also want to make sure that the vehicle side and trailer s

• Can a Combined Stop and Turn Signal Circuit be Converted to Separate Circuits
  
• Yes, there is a special converter, # 118158, that takes the combined circuit and separates out the signals to give you just turn signals and just brake lights on separate wires. You will install this converter on the trailer side, behind the connector. The left turn/brake goes to the yellow wire, the right turn and brake goes to the green wire. Make sure to ground the white wire. On the out put side the red wire is the brake lights only, yellow is left turn only, and green is right turn only.

• Adding a Third Brake Light to Trailer
  
• Although it is not required by law, what you are wanting to do is certainly possible. Because trailer tail light systems combine the stop lamp and turn signals for each side onto a single circuit, you will need to use a vehicle-to-vehicle tail light converter, part # 118158 to split the brake light circuit back out. The white wire on the input side of the converter would ground to the trailer frame, the green input wire would tap into the right turn circuit on the trailer and the yellow in

• Wiring # PK11700 Pollak 7-Way Trailer Connector
  
• The white wire is typically ground, you can confirm this by checking to see if it connects directly to the trailer frame. Your yellow wire is usually the left turn and brake lamp, green is right turn and brake light. The yellow/black and green/black are running lights, with the green/black running down the passenger side and the yellow/black running down the drivers side. You can confirm this by using a car battery, grounding the white wire to the negative terminal, and applying 12-volts to each

• No Power on the Left Turn and Brake Light 7-Way Trailer Connector Pin on a 2007 Chevy Tahoe
  
• The problem is that on your 2007 Chevy Tahoe, the turn signals on the vehicle are on a separate circuit than the brake lights. Trailers use a combined stop and turn circuit. When trailer wiring is added to a vehicle, vehicles with separate turn and brake lights get those signals converted to a single function by a converter whether from the factory or aftermarket. If yours is from the factory, it sounds like something has gone wrong but I can tell you what to look for. First, take a look in t

• Wiring a 7-Way Round Pin European Trailer Connector
  
• Usually a brown wire contains the running light circuit. However, you cannot go by wire color because it always varies from trailer to trailer. You will want to trace the wire back to where it leads on the trailer to determine its function and then make the connection in the trailer connector as needed. If you have a European 7-Way then it will be a little different. I have included a picture that shows the typical functions of a European 7-Way.
