• Boat Trailer Pulled by 2001 Chevy 1500 Has Lights That Will Not Work When Brakes are Applied
  
• I would suspect a poor ground connection on the trailer. Most trailers use a ground connection at the front of the trailer, with each lamp picking up its ground connection by its physical contact with the trailer frame, in effect, using the trailer itself as part of the ground circuit. Take a look at the grounding point for the trailer connector, it can usually be found on the trailer tongue near the coupler. Make sure that this ground connection is tight, and connected to clean metal. If the

• Troubleshooting Trailer Running Lights Not Working Using a 7-Way to 5-Way Adapter, 2008 GMC Yukon
  
• You will want to make sure that the 5-Way portion of the adapter is pinned out to match the 5-Way on the trailer. You will need a circuit tester like the Quickee # 3808. Test the adapter when it is plugged into the 7-Way on your 2008 GMC Yukon to determine which pin is for the running lights. Then make sure the corresponding pin on the trailer side connector matches. If not, you will need to re-pin either the trailer side connector or the adapter to match. If there is no signal at the adapte

• Troubleshooting Running Lights Not Working on a 2008 Chevrolet Silverado after Installing Wiring
  
• I would start troubleshooting at the connector itself. Take the connection apart and make sure there are no bent pins or corroded terminals that could cause the tail light function not to work. Next, I would check the fuse block under the hood of the truck. There should be a slot for a tow package fuse in there. Check the legend under the fuse block cover and you may find that this fuse is missing or that it has blown, and needs to be replaced. Finally, check the connector at the rear of t

• Can a 4-Way Flat Trailer Wiring Connector be Added to a 2010 Chevy Silverado
  
• A 7-way will have a round socket and blade-style pins in it. The 2010 Silverado would either have a 7-Way connector or no connector. If the connector is present, use a circuit tester like the Quickee # 3808 to test the function on the pins while someone sits in the truck to turn them off and on while you test. If there is no connector, you would need to install # PK11916. All of the wiring will already be present, you would just need to plug this connector in. If you wanted to change it over

• Can 4-Pole Trailer Adapter, # 118384 Be Used at the Same Time as Another Connector, 2010 Dodge Ram
  
• The 4-Pole Trailer Adapter, # 118384, is a T-style connector. When plugged into a truck that has an existing factory trailer connector, that factory trailer connector will remain functional and you will be able to use either one. However, I advise against using more than one of the connectors at the same time. Doing so can overload the circuits and cause electrical damage. I have included a link to the installation details for this harness for you to view. The harness itself is rated for 7

• Attaching a 7-Way Trailer Wiring Harness to a 2000 Oldsmobile Bravada
  
• It sounds like your 2000 Olds Bravada did not come with a factory installed 7-Way wiring harness.

It could still potentially work but you will need to make sure that the white wires are grounded to the vehicle frame in a spot that is clean and free from corrosion.

• 2005 Nissan Titan Trailer Lights Not Working Using Tow Ready Wiring Harness
  
• If your 2005 Nissan Titan came with a tow package and a factory installed 7-Way trailer connector then it may be easier to use a simple adapter, like # PK12716, to go to a 4-Way. If your truck did not come with a 7-Way at the back, then you would probably need to add some relays, # C57000, to make the wiring fully functional. The relays are required for trucks that did not come with a factory tow package.

• Grounding Problem on RV Towed by 2004 GMC Sierra
  
• The fact that everything pretty much works fine until the headlights are switched on tells the story. What you are experiencing is the classic symptoms of an insufficient ground connection. When the headlights are switched on, the wiring system of the trailer is drawing full amperage, which is when a problem will manifest itself. Make sure that the ground connection on the RV is securely connected to clean metal on the trailer frame. You can find this connection by tracing the white wire
