Expert Answers about Toyota Tacoma

• Recommended Replacement 4-Pole Wiring Harness for 2001 Toyota Tacoma
• Nice job recapping your troubleshooting efforts with the trailer lighting issue. I agree that based on your testing results it does appear the converter in the harness is toast. If it has been in service in the 2001 Tacoma for all these 16 years then you totally got your money's worth! Although we offer wiring from many good brands we do find that the best reliability tends to come with Tekonsha products. You can use the plug-and-play 4-pole harness # 118379. I recommend using dielectric...

• Troubleshooting Right Tail Light That Stays On and Flashes When Brakes Are Applied
• It sounds like the right turn signal wire on the trailer may have somehow been shorted to the running light wire, which is what is causing the light to stay on. I recommend checking these and the other trailer wires for any damaged or exposed areas that might be making contact with another wire or bare metal surface. Also check to make sure that the connector itself is free of any dirt or debris, as this may also cause a short. Lastly, make sure all your ground connections are secure and...

• Why Would Trailer Wiring Only Ground Through Ball Mount on a Trailer
• Typically what you described is due to an insufficient ground on the trailer and not the vehicle. You can try running the grounds of the lights back to the main ground of the trailer and that should fix the problem. Or if the main ground strap of the trailer is attached to a painted surface you could try removing the paint and connecting it to a bare metal surface. Or you can try testing the pins of the connector on your tow vehicle with a circuit test like part # PTW2993 using the ground...

• Troubleshooting Non-Functioning Lock Cores On A Rola Haul-Your-Might T3 Truck Bed Ladder Rack
• If the locks on the crossbars of your Rola Haul-Your-Might T3 Truck Bed Ladder Rack # 59799 aren't wanting to turn then they either are clogged up with something and you can try to spray them out with some WD40 or you might be using the wrong key. I would double check that you have the correct key and didn't accidentally swap it out with the keys from an other accessory that you have. If you still can't get the locks to properly operate you can most likely order replacement lock cores through...

• Do You Have Any Mounting Brackets to Raise My Rhino-Rack Batwing Awning's Height?
• I have a solution for you. Unfortunately, there are no particular brackets that will raise your Rhino-Rack Batwing Awning in addition to the brackets you already own. A creative solution for raising your trailer a few inches are leveling blocks like the Ultra-Fab Leveling Blocks for Trailers and RVs # UF48-979051. With the leveling blocks, you will be able to stack the blocks under your trailer's tires in order to raise the overall height of the trailer. This will give your awning a height...

• What Typically Causes Weak Trailer Brakes
• Weak trailer brakes are typically caused by the brakes not being adjusted properly which you can check to see if they need to be adjusted tighter. You'd want to adjust them until there is a light drag on the wheel when turned by hand. Another possibility is that the brake output circuit is using too thin of wire which 10 gauge is the minimum for that like # 10-1-1. Or a grease seal could have blown and your drums now too slick to stop the trailer.

• Troubleshooting Trailer Lights not Working with a 4-Way to 6-Way Adapter on a 2005 Toyota Tacoma
• Before attempting to install a new 6-way connector, I would recommend using a circuit tester, # PTW2993, to test the connectors on your 2005 Toyota Tacoma and on the trailer that you are using to see if something is not wired correctly. When you have the adapter connected to your 4-flat connector, test each pin for proper function. I would also recommend testing each pin on your 4-flat connector as well, just so we can determine if the problem is on your 4-flat connector, the adapter, or...

• Troubleshooting A Tekonsha Prodigy P3 That Will Not Turn On
• It is possible to reset the Tekonsha Prodigy P3 # 90195 by unhooking your trailer and unplugging the controller for 15 minutes. If you are 100% sure you are getting power, but the screen does not turn on, in some cases a reset will correct this. We also recommend checking your trailer connections and thoroughly cleaning the contacts on both the vehicle and trailer side. Sometimes corrosion can cause issues with the brake controller, and since it has not been used in a long time, this will...

• Installing a Swivel Jack on the Frame of a Cargo Trailer
• The etrailer Round Snap Ring Swivel Jack w/ Footplate # TJB-2001S-B is a swivel jack that is designed to be welded on to the frame of a trailer. If you are looking to use hardware to install a jack rather than welding the jack to the frame, I recommend the Pro Series Round Swivel Jack # PS1400300303. The Pro Series jack is a bolt-on swivel jack that includes the hardware needed to mount to your trailer frame. This jack will fit frames up to 3 x 4 inches. The jack is similar in cost and...

• Troubleshooting Tekonsha PowerTrac Brake Controller on a 2018 Toyota Tacoma
• To determine if your Tekonsha PowerTrac # 39523 is bad or not all you need to do is test the blue wire coming from the controller with a circuit tester like part # PTW2979. Put the power to the highest setting and then use the manual override to send power along the blue wire to your trailer brakes. If the blue wire on the PowerTrac isn't sending power but it is receiving power on the black wire then the controller is bad and you need to replace it. The PowerTrac and the Voyager # 39510...

• Troubleshooting Tail Light/Turn Signal Issue on 1993 Skyline Aljo
• It sounds like you have a short in your wiring or a bad ground. I recommend using an incandescent circuit tester like # PTW2993 over a multimeter like # PT89ZR for this application. I recommend first ensuring your trailer connection pins are clean using some sandpaper and some dielectric grease like # 11755. Your passenger side stop/turn will be on a separate pin so you want to make sure you are getting power there. Next, check your ground connection to make sure you have a bare metal...

• License Plate Light Blinks With Turn Signals On Trailer
• It sounds like you have tested the vehicle side trailer connector and everything was working correctly therefore that would point to the trailer as being the cause of the problem. In regards to the brake lights blinking with the turn signals activated, this is completely normal as the trailer brake and turn signals are on the same circuit. However, if the license plate light also blinks then you have a short on the running light wire which is usually brown. Therefore, you need to trace...

• Trailer Brakes Only Work When Manual Switch on Brake Controller is Activated
• The controller is only putting out voltage when the manual switch is applied on the brake controller, but not when the vehicle brakes are applied, is that correct? The most likely problem is that the controller is not getting the input that the vehicle brakes are being applied. When the trailer is hitched up with the transmission in park, use a circuit tester like part # 3808 on the red wire exiting the rear of the controller. You should show voltage on the wire when the trucks brake pedal...

If the blinker circuits are still functioning on the trailer wiring but the brake light circuit is dead then that would indicate the circuit board isn't functioning properly and would need replaced.

• Troubleshooting Lights Dimming When Brakes are Applied with Trailer Connected 2012 Toyota Tacoma
• There are a couple issues you may be having. You may have a bad ground or short on your trailer wiring and when you hit the brakes the short causes an excessive drain on your vehicle battery and your lights dim. If you see the voltmeter on your dash dive when this happens then you know this is happening. You could have a weak battery or alternator, around here you can have those things tested at local car part stores. You may also just have too many lights on your trailer and there is...

• Tail Light Fuse Blows On 2000 Toyota Tacoma When Trailer Is Connected To The Trailer Hitch
• Since it is blowing the fuses only when the trailer is connected to the hitch it is probably a short on the trailer wiring. You will want to start by testing the installation of the T-One Vehicle Wiring Harness, # 118379. Without the trailer hooked up you will need to use a circuit tester like part # PTW2993 and test each wire going into the black converter box on the T-One Vehicle Wiring Harness, # 118379, as its function is activated. With somebody to turn on the turn signals and step...
