Left Turn Signal On 7-Way Trailer Connector is Not Working
It is possible that there is a blown fuse or relay related to the tow package wiring that is causing the problem. Use the vehicle owners manual to find the locations. It is also possible that there is a break in the wire somewhere. You will need to use a circuit tester like # 3808 if needed to test the wire as you work your way forward on the truck. If the right side stop light also does not work it could be a blown stop light or CHMSL fuse. If the turn signal function works on that same

Parts Needed to Convert a 4-way to a 5-way for a Honda Odyssey Towing Surge Brake Boat Trailer
You are going to need to install a Adapter 4 Pole to 5 Pole # 20036. This product will plug right into your 4-way and then you will run the blue wire from the adapter to your reverse light circuit and then you will have a fully functional 5-way that will allow the trailer brakes to release when you reverse your trailer. I attached an install video for this product to show you how it installs.

Fuse Location for Trailer Wiring Harness 118255 for a 2010 Lexus 450h
I spoke with my contact at Tow Ready about wiring harness # 118255. He stated that the build sheet for he harness only shows one fuse included. However, it is possible that you may need to install a fuse in a fuse panel to make everything fully functional. Before doing this, you will want to determine if the wiring harness is functioning by using a circuit tester like # 3808 if needed to test the 4-Way while someone runs through the lighting functions on the vehicle. If you have only one fuse

Trailer Lights Not Working After Install Wiring Harness on a 2014 Kia Sorento
To determine if the problem is with the vehicle or the trailer, first disconnect the trailer from the vehicle. Then use a circuit tester like # 3808 or the one that came with # 119147KIT. Test the pins on the 4-Way using the circuit tester while someone sites in the vehicle and runs through the functions. If all the signals are correct on the 4-Way when you test it then the issue is on the trailer. But if the signals are not correct then there is a problem with either the wiring harness, inst

7-Way Trailer Wiring Harness Stopped Working On a 2011 Honda Pilot
The first thing I recommend doing is checking the vehicle side connector for dirt and corrosion build up at the 4-Way. I had a friend that had this problem. The 4-Way had enough corrosion in it to cause the lights not to work. After clearing it out, it worked fine. You could use a circuit tester such as # 3808 if you do not have one to test the wires at the back of the 4-Way to determine if the signal is getting through to that point. That would confirm a problem with the plug, most likely co

How to Adapt a 6-Way Vehicle-Side Trailer Connector to a 7-Way
Since your vehicle already has a working 6-way connector for your trailer that uses electric brakes, you will not need to install any additional fuses or relays in order to change to a 7-way connector. The simplest and most cost-effective option is to use an adapter to convert your 6-way to a 7-way. You will need to test the wire functions on your existing 6-way since these connectors can be wired in two different ways: center pin as brake signal, or center pin as 12V power. You can use a cir

Adding a 7-Way Trailer Connector and Brake Controller to a 2010 Ford Ranger Sport
If your 2010 Ford Ranger originally came with a 7-Way from the factory you would use # 20119 to replace it. If your truck came with a 4-Way wiring harness then to add a 7-Way you would use # ETBC7. A plug in type of harness for a brake controller is not available for the Ranger. A brake controller would have to be hardwired in. I have included some helpful links that explain the ETBC7 and hardwiring of a brake controller for you. For a brake controller I recommend the Tekonsha P2, # 90885. It

Looking For a Pigtail Connector With 2 Grounding Wires for a 2001 Dodge Ram 2500
I have some suggestions, that I am sure you have tried, but, I want to offer to be sure. Make sure that your connections are seated properly. Either the ground or brake output wire pin inside one of the connectors may be bent or damaged therefore not permitting the proper current through. Check to be sure that the ground and the brake-out pin inside all of the connectors is solid and not loose. Based on the issue you are describing, it seems the problem is within the fifth wheel harness.

Installing a Brake Controller and 7-Way on a 2007 Dodge Sprinter RV
Since your 2007 RV on the Sprinter chassis already has a trailer connector but it does not match either trailer, using the 4 and 7 way installation kit # ETBC7 would be a good idea. This will also provide you with the accessories needed to install the P2 brake controller # 90885.

How do I Determine if a Santa Fe 2013 2.0T limited has a Towing Package
The best advice I can give you for determining whether or not you have the tow package wiring would be to try contacting a different Hyundai dealership. With your VIN number they should be able to tell you for sure if you have the tow package. The factory tow harness is located under the passenger side of the vehicle near the rear tire along the frame. If you find the harness that does not necessarily mean you have the tow package as some times other connections or harnesses could be missing.

Electric Trailer Brakes Stay On when Towed by a 2006 Ford F-150
First, it is possible that the relay that was installed actually has more than one function as it does seem odd that the horn would be related to trailer brake output. I wonder if the horn stops working too if that relay goes bad. You can consult the owners manual and/or the power distribution box lid for the locations and functions of all fuses/relays. If adding the relay fixed the issue the first time then it is possible that the relay has gone bad again. They would need to figure out why

Troubleshooting Malfunctioning Turn Signals on Utility Trailer Towed by 2006 Chevy Silverado
The first thing you will need to do is to test the 4-pole connector on the truck. This will tell you if the wiring problem exists on the truck or on the vehicle itself. The pins on the connector fed by the yellow and green wires should light up your tester when the right turn, left turn and brake lights are activated. If you do not get any signal on the right or left turn pins, you most likely have a blown fuse. Check the fuse box under the hood. If the 4-pole connector tests okay, you

Troubleshooting a Blown Trailer wiring Harness on a 2012 Ford Edge EcoBoost
I hate to say it, but the company who installed your harness is probably right. We see what you are describing pretty often and the problem is almost always a short on the trailer.

The reason the box will short out and not the fuse is because the fuse is between the battery and the converter, whereas the short is on the other side of the converter box.

Isolation Solenoid Recommendation for Preventing a Trailer Battery from Draining Vehicle Battery
What you could do is install a Tow Ready Battery Isolation Solenoid part # TR118665. You would install this inline with the 12 volt power circuit of your vehicle.

What this will do is make it so that it will only allow current to go past the solenoid when the key is on.

You will have to run the battery wire of the T-One Vehicle Wiring Harness # 118412 to install it on your 2012 Toyota RAV4. This is a powered unit that draws all its power from the vehicle battery to power the taillights of your trailer. This protects the delicate tail light circuitry of your vehicle from being overdrawn. Basically, it just uses your taillight circuits as signal wires and draws the power from the battery. The unit would not function without being run to your vehicle battery.

Recommendation for Replacing a 7-Way Plug that Was Cut Off a 2007 GMC Sierra 2500
