• Troubleshooting Turn Signals Not Working On Trailer Pulled by 1999 Ford Ranger
  
• The Tow Ready Custom Fit Vehicle Wiring, # 118325, is the correct wiring harness for your 1999 Ford Ranger, and it does have a converter. Your trucks turn signals are separate from the brake light circuit on your Ranger. If the lighting kit you installed on your trailer had a lot of lights, like extra lights on the side, the amperage draw might be too much for your vehicles wiring system. If this is the case, you will need to upgrade to a Upgraded Circuit Protected Modulite, # 119176KIT. This

• Troubleshooting Broken Ground Pin on Trailer Wiring Harness for a 1994 Ford Ranger
  
• The only wiring harness we carry for the 1994 Ford Ranger is the T-One Vehicle Wiring Harness, # 118325, that you have referenced. The black converter box does contain some electrical components that could potentially go bad. But if you are consistently having a trouble with the same wiring harness, it may be a symptom of another problem. You did mention the ground post breaking off. This could occur if there is corrosion build up in either connector, making it difficult to connect and discon

• Troubleshooting Wire Harness Short Circuit on a T-One Trailer Wiring Harness with Converter
  
• It sounds like the converter on the T-One Wiring Harness, item # 118325, is shorted. There are many reasons which could cause the converter to go bad. Most often connecting to a trailer that has a short in the wiring is the cause.

• Tail Lights and/or Brake Lights On and Use Turn Signal One side Brightens-Other Side Light Goes Dim
  
• It sounds like you have one of two problems. Either the wiring on the 1995 Ford Ranger is not converted as it should be to allow the brake and turn signals to work on the same circuit correctly, or there is a ground issue on the trailer that is showing up when the brakes and turn signals are applied at the same time. If your trailer wiring does not have an inline converter, like the black box on the # 118325 T-One Harness, then you will need to purchase one and install it. The #118325 harness

• Troubleshooting a Shorted Out T-One Vehicle Wiring Harness # 118325 on a 1996 Ford Ranger
  
• It sounds like the # 118325 might be bad since you checked the voltage before the unit and there was power but after there is not. However, since this is the second one of these you have gone through it sounds like you might have a short somewhere on the trailer that is causing the # 118325 to short out and quit working. I would recommend you go over your trailer wiring and check for any bad grounds, loose wires or corrosion and fix as necessary. I attached installation instructions for

• Trailer Tail Lights and Running Lights Do Not Work When Connected to 1994 Ford Ranger
  
• This is a strange situation because on a trailer, the brake lights and turn signals are on the same circuit. Unless your trailer has turn signals that are separate, it should be a standard 2 wire system. What may be occurring is a bad ground, a alternative wiring situation on the trailer, or a bad converter box. First, testing the converter is simple. Start by disconnecting the trailer. Next, use a circuit tester like # 3808 to first test the signals going into the converter and then coming o
