• Troubleshooting Wiring on a 1990 Toyota Pickup While Installing Curt # C55379 Harness
  I have some suggestions to help troubleshoot your wiring issue with your 1990 Toyota Pickup and the Curt Harness # C55379. Make sure your truck is running when you are testing the trailer lights, not just having the truck in the accessory mode. By having your truck running your trailer will be receiving maximum voltage because the alternator will be running. Check your trailer connector with a circuit tester such as # PTW2993 to verify that you are receiving voltage on each pin. If you...

• Recommended Trailer Brake Controller and Wiring Needed for 2000 Toyota 4Runner
  For your 2000 Toyota 4Runner, I recommend the Tekonsha Voyager Trailer Brake Controller - 1 to 4 Axles - Proportional # 39510 with the Brake Control Plug-In Harness # 20127. This is the best controller under the price point you are seeking. Then for your wiring, if you already have a 7-way connector you can use the kit # 5506. If you have a 4-way then you will use the # ETBC7 kit which comes with the 7-way adapter and wiring. If you don't have a 4-way, then you will need that first and...

• Troubleshooting Trailer with Non-Functioning Turn Signal Lights Behind a 1992 Toyota Pickup
  This is the right harness for your 1992 Toyota Pickup. It sounds like you might be having a ground issue. Check the ground wire from the harness. Make sure it has direct metal to metal contact with the frame or body. Rust, corrosion and paint can insulate an electrical connection. Check the grounds for the tail lights on the trailer, make sure they have good metal to metal contact. Finally, check the the trailer ground wires, make sure again, that they have good metal-to-metal contact. You...

• Can a Blown Trailer Wiring Harness Converter Box be Repaired or Does it Have to be Replaced
  If a converter box is blown then it will need to be replaced because there are no user serviceable parts inside. To determine if a converter is bad you will want to test the wires going into the box and the wires coming out with a circuit tester like # PTW2993 if needed. If the signals are correct going in but wrong coming out, then the converter is bad and will need to be replaced. I have included a link to a video that might help. You will want to determine what caused the converter...

• Parts Needed to Tow Camper With Brakes Using 2004 Toyota Tacoma
  Hey Johnathin! What kind of camper do you have? For a complete setup on your 2004 Tacoma you will need a hitch, wiring, brake controller, and ball mount. Starting with the hitch I recommend the etrailer # e64AR. This Class III hitch has a 2" receiver, bolt-on installation, matte black finish, and a limited lifetime warranty. For wiring you need to start by adding a 4-way. The T-One Vehicle Wiring Harness # 118379 will plug into the connection points behind your tail lights and provide...

• Trailer Wiring Harness Recommendation for a 2004 Toyota Tacoma PreRunner
  I recommend using the T-One Wiring Harness # 118379 for your 2004 Toyota Tacoma PreRunner. This tees in behind the tail lights and gives you the basic 4-Way wiring needed to activate your trailer light functions. I also recommend picking up the mounting brackets # 18144 and # 18140 so you can keep the 4-Way connector next to your hitch receiver. Attached are some videos for you to check out.

• Troubleshooting Hopkins 3-2 wire Converter HM48847 Only Having 9.7v Out Of Converter
  I reached out to my contact at Hopkins and the Hopkins Tail Light Converter - LED Compatible # HM48847 you have should have a full 12 volts exiting the converter. She recommended checking that the ground wire is connected to clean, corrosion free metal, but since you have already checked this then this is likely not the cause. Are the tail lights on your 1999 Toyota Tacoma the factory tail lights? or have they been changed with aftermarket ones? If not it really sounds like the converter...

• Comparison of Tekonsha and Curt Wiring Harnesses for 1999 Toyota Tacoma
  The amp draw on the product pages for both the # 118379 and the # C55379 wiring harness is how much draw the harnesses are designed by their manufacturers to handle. The amount of draw will be determined by the lights on your trailer. The Curt is designed to handle a little more than the Tekonsha harness, however they've both been tested on a 1999 Toyota Tacoma like yours.

• Differences Between The 4-Way Wiring Options For 2002 Toyota Tacoma
  There are not many differences between the Tekonsha T-One Vehicle Wiring Harness part # 118379, Curt T-Connector Vehicle Wiring Harness part # C55379 and the Hopkins Plug-In Simple Vehicle Wiring Harness part # HM43315 for the 2002 Toyota Tacoma besides the brand names.

• What Do I Need to Wire a Basic 4-Way Trailer Connector on a 1996 Toyota Tacoma Pickup
  Since the 1996 Toyota Tacoma has separate turn and brake signals, a converter is necessary. Fortunately, there is a plug-and-play harness, part # 118379, available for your Tacoma that makes installing very easy. It simply plugs in-line with the tail light connectors behind the tail light housings. Then you connect the ground wire to a good ground point on the truck frame and you are done. I have added a link to the part and a video of it being installed on a 2000 Tacoma. I have also included...

• Parts Needed to Add Electric Brakes to a Utility Trailer with a 3500 Lbs Axle and Brake Flanges
  You will need several items to add electric brakes to your Carry-On Utility trailer. Starting with the trailer you will need a hub and drum that matches the bearings and seal on your trailer spindle and your wheel bolt pattern. The only way to be sure is to check the bearing part numbers and seal part number, but with a 3,500 lbs Dexter axle that has brake mounting flanges you will most likely have the # L44649 Outer and # L68149 inner bearings and # 58846 seal. If these are the correct...

• 7-Way Recommendation for 2001 Toyota Tacoma with Reverse Light Circuit Active
  Since we don't have a 7-way kit for your 2001 Toyota Tacoma the best solution is to start with a 4-way that fits your 2001 Toyota Tacoma like part # 118379 and then convert to a 7-way with # 37185 and connect just the reverse light circuit of the adapter (purple wire) to the reverse lights of the vehicle and you'd be set with the easiest solution to what you are needing.

• Troubleshooting Trailer Wiring Harness on a 2004 Toyota Tacoma
  The issue you're having is almost always caused by a week ground. It's strong enough to handle the power draw of the running lights or the turn and brake signals but not both at the same time. I would start be reconnecting your grounds to clean bare metal connections. Or if the trailer lights are grounded through the mounting hardware make sure the studs are clean and free of any corrosion. If this doesn't solve your issue you'll need to inspect the wiring. If you still can't find...

• Trailer Wiring Harness Converter Box Failed on a 2003 Toyota Tacoma
  The converter box alone in a trailer wiring harness such as # 118379 for your 2003 Toyota Tacoma cannot be replaced. The whole harness would have to be replaced. Since you have determined that all of the electrical signals going in are correct but not correct on the output side of the converter this does indicate a bad converter. But, if the converter stopped working because of a short somewhere on the trailer you will want to fix the short or the problem will keep happening. Make sure...

• Trailer Brake Lights Not Working when Connected to a 2003 Toyota Tacoma
  Does your 2003 Toyota Tacoma have a factory tow package and trailer connector? If so then it could be a blown fuse associated with the tow package wiring. Many times, the tow package wiring is separate from the vehicle tail light wiring so the truck brake lights working would make sense. If it is an aftermarket wiring harness such as # 118379 then it is strange that the brake lights on the trailer are not working because the brake lights and turn signals are on the same circuit. This...

• Hitch Recommendation for a 1994 Toyota Pickup Truck
  Yes, the Curt Hitch part # 13086 that you referenced has been confirmed to fit your 1994 Toyota Pickup. It will fit your truck that doesn't have a bumper, and as long as the bumper you plan to install is an OEM bumper there wouldn't be any interference. This hitch won't interfere with your spare tire either. If you plan on doing some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4...

• Troubleshooting a Pinched 4-way Trailer Wire Where Only the Running Lights Function
  It sounds like you may still have some bad connections left in your 4-way trailer wire harness. I would go back and inspect all of the wires that got pinched and make sure they are all making good connections to the correct color wire. You will also want to make sure they are taped up and insulated well from each other to prevent the wires from shorting out on each other. If that does not fix the problem I would go back and look for other areas of the harness that may have been damaged...

• 4-Pole Wiring Harness for 2002 Toyota Tacoma
  We offer two trailer wiring harnesses for your 2002 Toyota Tacoma, the Draw-Tite # 118379 and the Curt # C55379. Both harnesses are the plug-and-play type that will install in a similar manner at your Tacoma taillight assemblies as shown in the linked video. Given your choice of trailer lighting kit # TL5RK I suggest you opt for the Curt harness since it offers higher current output capacity than the Draw-Tite. Curt # C55379 provides maximum output of 3 amps per stop/turn circuit and 7.5...
