• Troubleshooting a 7-Way Install on a 2012 Jeep Grand Cherokee, Brakes Work but no Turn Signals
  It sounds like you may not have the tow package on your 2012 Jeep Grand Cherokee, you should head to your dealer and have them reflash your bcm so that you have all functions of your trailer connector. If you do have a tow package the first thing you will want to do is use a circuit tester like our part # PTW2993 and test the functions of the 7-way to determine if the problem is on the vehicle or the trailer side of the setup. Check out the video I attached that shows how this is done. If...

• 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...

• Troubleshooting Brake Controller Not Showing Connection
  Have you checked the pins of your 7-ways for corrosion? Typically when this exact problem occurs on trailer wiring the issue is that there's just a bit of corrosion on the 7-way pins which then prevents the output circuit of the controller from making a solid connection. If you take some sandpaper to the pins of the connector you should see the circuit make connection again. I also attached a link to a page that has troubleshooting info on brake controllers for you to check out as well.

• Parts Recommendation to Install a 4-way in a 2012 Toyota Tundra
  Yes, the # HM11141835 that you referenced has been confirmed to fit your 2012 Toyota Tundra and would install in the connectors you have found behind the bumper. Or, if you have a factory 7-way and you want to keep it functional and have an additional 4-way for the light bar you could use the # 118384 instead. This will plug inline with your 7-way and will provide you with an additional 4-way for the light bar. I attached a page that has all of our under tailgate lights we offer that...

• Will Plugging in a Rampage LED Light Bar Disable Backup Sensors on a 2009 Chevy Suburban
  It is likely that if you were to plug in the 4-Way, # 118384, and then plugged in the Rampage light, # RA960134, it would still shut off the back up sensors. This is because you are teeing into the factory harness so there would still be power draw through the factory wiring. To prevent that from happening you would need to hardwire in a 4-Way to the tail light wiring on your Suburban using # C59236. Since it pulls power from the vehicle battery and signals from the tail light wiring it...

• Fuse Installation to Activate 4-Pole Trailer Wiring in 2009 Chevy Silverado 1500
  If your 2009 Silverado has the factory tow package it could still be missing the fuses required to activate the tow wiring to which you connected part # 118384. This part is intended for vehicles that have the factory tow package and 7-way trailer socket. Install any missing fuses/relays that are labelled trailer or tow. Be sure to use fuses of the correct amperage value for each location in the power distribution box under the hood. The fuse locations you referenced, right stop/turn and...

• Troubleshooting Running Lights and Left Brake Blinker Not Working on Trailer
  First thing you should do at this point is test the 7-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Since it's one side of the trailer not functioning...

• No Brake or Turn Signals With Trailer Wiring Harness On a 2007 GMC Acadia
  I am not sure which exact trailer wiring harness you are using but if you have one that plugs into the factory tow package plug like the T-One Vehicle Wiring Harness part # 118384 for example then the issue you are having would lead me to believe that you are missing some fuses/relays or they are blown. I took a look in your owner's manual and it lists two fuses for the stop/turn signal lights, "LT TRLR STOP/TRN" for the left stop/turn circuits and "RT TRLR STOP/TRN" for the right stop/turn...

• What is the Difference Between CURT Class III Trailer Hitches for a 2011 Jeep Grand Cherokee
  The main difference between CURT Trailer Hitch C13075 and # C13065, is the cross tube. On C13075, it has a round tube and the receiver extends straight out from the side of the tube. This requires a bend in the cross tube which makes more of the hitch visible beneath the vehicle. Hitch # C13065 has a square cross tube. The receiver is welded to the bottom of the square tube and this makes only the receiver visible beneath the rear of the vehicle. The rest of the hitch is hidden behind...

• Malfunctioning Right Turn and Brake Lights with Factory Installed 4-Way Trailer Connector
  Since you have a factory 4-Way and 7-Way, they will be wired to the same harness on the vehicle. The extra 3 wires for the 7-Way go directly to the plug but the 4 shared light wires should be split. We need to determine if the problem is between the 4-Way and the harness connector or if it is further up the harness in the vehicle wiring. Open the cap for the larger round 7-Way at the rear of the vehicle. As you look into it, the blade pin in the 3:00 position would be for right turn and...

• 7-Way/4-Pole Trailer Connector to Replace Existing 7-way on 2012 Honda Pilot
  Take a look at your existing 7-way, you'll need to stick your head under the rear bumper so you can see the rear of the connector. If the factory tow package harness can be unplugged from the rear of the 7-way (see photo), then I'd recommend using a T-connector like # 118384. You'd simply unplug the tow package harness from the back of the existing 7-way, and plug the # 118384 inline between the tow package harness and the 7-way. I've linked to a video showing a typical installation. If...

• Troubleshooting Trailer Wiring with Lights Not Working Completely
  I think I can help but it still sounds like a ground connection issue. Here is why...whenever some functions work and others do not, it is either a connector issue, a short in the wire, or a weak ground. Since everything works on both the trailer and truck when tested independently, and when you partially plug in the system it seems to work better than fully plugged, it definitely sounds like a ground issue. Since you have already cleaned up your grounds, I recommend moving them. Make...

• Troubleshooting Trailer Turn Signals Malfunctioning with 2007 GMC Acadia with 4-Pole Wiring
  The problem you describe, both trailer turn signals activating when either turn signal on the Acadia is engaged, is typically a grounding issue. Since you have already re-worked both the vehicle and trailer main grounds to ensure both are solidly connected to clean bare metal surfaces, then the most likely cause for the problem is either a bad wiring harness on the Acadia or some issue with your adapter. I could not find purchase history to let me see the specific wiring harness and adapter...

• Making 5-Way Adapter that Installs Inline with 7-Way at Rear of Truck
  Since there isn't a 5-way adapter exactly like the # 118384 what you'd need to do is install the # 118384 and then use the adapter # 20036 to convert it to a 5-way like you need. You'd want to tap into the reverse light circuit ran to the 7-way at the rear of your truck for the easiest access. This will be the center pin of your 7-way.

• 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 # PTW2993 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 to...

• Trailer Running Lights Not Working with a 7-Way to 4-Way Adapter
  There are a couple of possibilities here. First, it could just be a ground issue on the utility trailer. You will want to check the main ground from the trailer connector and the taillight grounds and make sure they are attached to clean and corrosion free bare metal surfaces. A ground issue will show up when there is a load on the circuit and having a constant draw on the circuit like with running lights could be what is making the ground issue appear. Also, you can check the trailer...
