Video Transcript for Performance Tool Wiring - Tools for Wiring - PTW2993 Review

Speaker 1: Today we're taking a look at a hook probe circuit tester. Now, this circuit tester easily identifies shorts in six volt, 12 volt, and 24 volt circuits, fuses, test connections, and wiring harnesses. It's great to have around the house, it's great to have around the shop. It features a wire piercing molded hook that locks onto the wires to free your hands while working. All you have to do is push this up, it's spring loaded, place the wiring inside here. The wiring that you're wanting to test.

Let go, put your fingers on top, push down to pierce it, and that's all there is to it. The extended molded hook allows for testing in confined spaces or with limited access. It does feature a high intensity light bulb, and a four foot long cord, that's insulated and resistant to oil and heat.I'm going to go ahead and show you how to use it. I have a power box here, I'm going to zoom out so you can see exactly everything that I'm doing. I just have a power box that we use, mostly for testing lights and trailer wiring, and stuff.

What I'm going to do is, I'm going to turn that on, so with power running to it, that means that my 12 volt supply, which is my black wire here, has power. To test that, I need to hook this to my ground connection, it's just a big alligator clip. I'm grounded, and then I take this, open it up so that I have area or space to put my wire through, and then I just allow the little point to do its job. Push down, and then because I have power running to it, the light comes on.Now, if I don't have power running to it, it's going to identify that and my lights not going to come on. Again, it allows you to easily and quickly identify issues in your wiring.

It's a nice easy way to identify, and a nice easy to use system. That's going to do it for today's look at the hook probe circuit tester.

  • Troubleshooting Error on Front Right Jack of Ground Control Leveling System on Trailer
  • With the Error RF on your system, since the unit will not go up or down, I recommend checking the connection wires on that jack. If there is a lack of power to the jack, this error will occur. Test the wires using a circuit tester like # PTW2993. Next, test the jack using a 12V jumper wire and ground while disconnected from the system. This will help you know if the jack is bad, or if there is a connection that is bad. If the front leg is bad, you can use the Replacement Lead Leg for...

  • How Does 7-Way and Brake Controller Install in 1973 Ford F-350
  • For a truck as old as yours it would be pretty hard to find a wiring diagram for installing the 7-way part # 20023 but I can help you figure it out using a circuit tester like the part # PTW2993. Basically you are going to need to test all of the wires of your taillights to determine their function and then wire to the 7-way using the included diagram. Now hardwiring in a brake controller will be a similar process but you'll only have to test the wires at the brake switch till you find...

  • Installing Furrion Side Marker Light with Camera on 2019 Momentum 351M
  • The Furrion Side marker lights with camera # FCE48TASL you will have the running light wire (brown) camera power (red) and ground (black). Because it sounds like you have two sets of wires, it is likely one set is running light power and the other is the ground. You can use a circuit tester like # PTW2993 to determine function. Once you have done so, the brown and red wires connect to the running light power and the black will connect to ground. This will give you camera power as long...

  • Can 6-Way on Towed Vehicle be Hardwired to 7-Way Connector on RV
  • The easiest way to connect your towed vehicle to the 7-Way on your RV will be to use a cord like the Blue Ox 7-Wire to 6-Wire Coiled Electrical Cord # BX88206. This will allow you to quickly connect your tow vehicle to your RV by using the included coiled cable that features a 6-Way on one end and a 7-Way on the other. If you would rather hardwire the 6-way wires from the towed vehicle cord to the 7-Way, you can certainly do this. You will just need to make sure that you make the proper...

  • Is Dealer Activation Required for Trailer Wiring Harness # C55384 on 2015 Jeep Grand Cherokee
  • When you install the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # C55384, it may be necessary to see a local Jeep dealer to activate the tow package wiring circuit. Some vehicles have the active tow package wiring and others do not, so you will know as soon as it is installed if this is required or not. If you test the function using a tester like # I26, a circuit tester like # PTW2993, or connect it to a trailer, you will be able to...

  • Troubleshooting 7-Way Trailer Connection Wiring on 2017 Nissan Frontier
  • In your 2017 Nissan Frontier, the Curt brake controller should be installed using the custom wiring adapter # C51382. This should work correctly to give you the proper wiring within your cab. Then you will use the Curt # C56226 or the Tekonsha # 118266 to get the correct 7-way. If you have done this even using the previous relays, check your trailer connection for functions using the attached photo and a circuit tester like # PTW2993. It sounds like the trailer may be mis-wired...

  • Installation of Brake Controller on 2015 Ford Transit T250 With Factory Tow Package
  • Since you already have the factory tow package in your 2015 Ford Transit T250, I recommend the Tekonsha Voyager # 39510 along with the harness # 20127 to give you your basic controller. This will need to be hardwired as your vehicle doesn't have the dash adapter. I recommend using a circuit tester like # PTW2993 to test wires for function before splicing. If there are no brake controller output wires and 12V power lined under your dash, then to hardwire your controller you will need...

  • Troubleshooting Constant Power on Drivers Side Tail Light of Trailer Connector
  • It sounds like you have a crossed wire after the fuse panel. Sometimes this happens inside the trailer connector, so I recommend removing your trailer connector and using a circuit tester like # PTW2993 to test each of the wire functions at the US Car Connection locations like you see on this harness # 20147. If this connection works correctly then you will want to replace the 7-way connector on your vehicle because it has an internal issue. If this is the case, I recommend the Hopkins...

  • Trailer Wiring Recommendation For 2017 Jeep Grand Cherokee
  • The Pollak 7-Way part # HM40975-11933 is a fit for your 2017 Jeep Grand Cherokee and would plug into a square connector at the rear of the vehicle. Most likely it's the connector you found already based on what you described. You might test the pins of the connector you found with a circuit tester like part # PTW2993. If they are active when vehicle taillight signals are on then this will work. If instead you do not have the tow package wiring complete the T-one kit part # 118727 would...

Unfortunately the direction from the manufacturer are for the Tundra as you stated. I reached out to the manufacturer and they can't give me the colors and functions you are seeking. The best way to determine the function of your wires so you can ensure your tailgate lock is connected properly is to use a circuit tester like # PTW2993 to test functions to...

  • Troubleshooting Lippert Steps With Wall Switch That Doesnt Stop Step Extending or Retracting
  • Since the Lippert Components Kwikee 25 Series Triple Electric Step # LC3658373 won't stay out when you flip the wall switch off, it sounds like you have the manual switch wired incorrectly. When the switch is off there should be no power getting to the magnetic door switch so the steps remain in whatever position you had them in prior to shutting off power to them. You can test the switch using a circuit tester like # PTW2993. You should have power to the switch on one terminal and...

  • Recommend Wiring For Adding 7-Way To Existing 4-Way Trailer Connection
  • For your 2000 Toyota Tundra, I recommend the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7 or the # 5506 if you already have the 4-way to 7-way connection. This will give you the circuit breakers, wires, and connectors to install a brake controller and add the 3 functions not included in your 4-way. The running lights and brake lights should work with your current 4-way, so you may want to check that trailer connection with...

  • Troubleshooting Truck Bed Cargo Camera on 2016 Ford F-350 with Factory Screen
  • For your 2016 Ford F-350, the Truck Bed Cargo Camera for 8" Factory Monitor - Switch Kit # 3460006 is the correct fit. I reached out to their tech and he said since you are getting the switch over to a black screen it simply sounds like you aren't getting 12v power to the camera for it to sent the signal back. You will want to use a circuit tester like # PTW2993 to test the black power wire going to that camera and then trace that wire to determine why power is not getting to the camera....

  • Installing Tekonsha Prodigy P3 Trailer Brake Controller on 2018 VW Atlas with Tow Package
  • The Tekonsha Prodigy P3 Trailer Brake Controller # 90195 that you referenced is an excellent choice and it will work great with your 2018 VW Atlas. If your VW Atlas is equipped with a fully functional 7-Way connector at the rear of the vehicle, then the controller just needs to be hardwired to the factory harness you found beneath the dash. On the brake controller, the black wire is for 12V power, the blue wire is for brake output to the 7-Way, the red wire is for the cold side of your...

  • Installing 7-Way Connector on 2007 Ford Expedition with Factory 4-Way
  • Since your 2007 Ford Expedition has the factory 4-Way connector at the rear of the vehicle, you will just need to install the Hopkins Adapter 4-Pole to 7-Pole # 37185 to complete the wiring and install a fully functional 7-Way. Vehicle manufacturers will often change the wire colors on their factory trailer wiring, as appears to be the case on your Expedition. Because of this, I highly recommend testing the wires on your vehicle with a circuit tester like # PTW2993 in order to determine...

  • Brake Controller Wiring For 2015 Ford E450 Forester Class C Motorhome
  • For your 2016 Forrest River built on 2015 Ford E-series Chassis, the Tekonsha Prodigy P3 # 90195 will be a great brake controller for you. It may be able to install using the # 3034-P in the box to the left of your brake pedal over by the emergency brake. I've attached a video of the older model for you to check out. If that connection is not present and you don't want to test a bunch of wires under your dash for possible function using a circuit tester like # PTW2993, then I recommend...

  • Troubleshooting Trailer Lights Not Working with Curt T-Connector Harness Installed on Ram ProMaster
  • Since all of the trailer lights worked fine when using a different vehicle, it does seem like you have narrowed down the issue to the wiring on your 2018 Ram ProMaster 1500. To further verify this I do still recommend testing the 4-Way connector on the vehicle with a circuit tester like # PTW2993. Test the pins on the connector while you have a buddy activate the signals in the van. If you aren't getting power to all the pins then I recommend testing the wires both before the converter...

  • Troubleshooting Brake Controller E2 Error Code
  • The Hopkins Agility Trailer Brake Controller # HM47294 you asked from is most likely too new to get that E2 code like the older models (it would be SC instead) according to my tech contact at Hopkins. With either the SC or the E2 code, it is showing a short in the blue output wire somewhere between the controller and the brake magnets. This can be due to a pinched or broken wire, a bad ground wire, or it could be from a bad magnet as you stated. I recommend using a circuit tester...

  • Troubleshooting Curt Trailer Wiring Harness # C56124 for 2012 Nissan Juke
  • There are a couple things to check before replacing the unit, which may be the answer. First, check your vehicle fuses as listed in your owners manual. There are specific fuses for trailer use on your vehicle. The second thing to check is the ground wire on your wiring harness. If the ground is bad and isn't getting the bare metal to metal contact it could have worked and then suddenly stopped working as you stated. Use a circuit tester like # PTW2993 to check functions. If all...

  • Troubleshooting the Electric Trailer Brake Controller on 2011 Chevrolet Silverado 2500HD
  • For your 2011 Chevy Silverado 2500 with integrated brake controller, the brake output wire will run directly from your controller to the 7-way. You can test the 5 o'clock pin of your connector for braking function using an incandescent tester like # PTW2993. An incandescent tester will draw power like a connected trailer would to give the unit signal that a trailer is connected to allow function. You can then use the manual override feature to test function. The light should get brighter...

  • Recommended 7-Way Wiring and Brake Controller for 2013 Hyundai Santa Fe
  • It's hard for me to say exactly how the 4-Way harness on your Hyundai Santa Fe is installed. The type of wiring you described in your question does not match up to how the wiring harnesses we have available for your Santa Fe will install, whether or not it has the factory tow package. If the Santa Fe does not have the factory tow package, the correct wiring harness will be the Curt T-Connector # C56184 or the Hopkins # HM11143984. Both harnesses will install by plugging into factory...

  • Wiring Wesbar Trailer Lights # 403026 and # 403076 to Trailer Wiring with Unknown Colors
  • Your Wesbar 102640 trailer light features a sealed capsule so the bulb itself cannot actually be replaced. I recommend simply replacing the light assemblies with the Wesbar # 403026 and # 403076. These are the newer/current generation model lights to what you currently have. On these light assemblies the white wire is for the ground, the brown is for the running light circuit and the yellow/green is the corresponding stop/tail circuit for either side of the trailer. You'd need...

  • The "N.C." message you are seeing displayed on your Tekonsha Prodigy Brake Controller, such as the P2 # 90885, essentially means that the brake controller is not detecting a trailer connection for some reason. I first recommend just making sure that you used the correct Plug-In Harness for your 2017 Frontier, which is the part # 3050-P. Otherwise, this error message be caused by a number of reasons. First, I recommend checking both the vehicle side and trailer side connectors for any...

It is usually a missing relay in the in-cab fuse panel and it is # 38666-1 but you can check the owner's manual for all fuse and relay locations to verify. The relay is attached to a wiring harness which is located behind the passenger side kick panel near the passenger door (see picture).
