Expert Answers about Tekonsha

  • What is the Difference Between the Tekonsha Prodigy P2 and the P3 Brake Controllers
  • Actually, the P3 now has the upgraded axis accelerometer like the P2. The Tekonsha P3 Trailer Brake Controller # 90195, will work with both electric over hydraulic brakes on the trailer as well as electric brakes. It has a menu option on the display that allows the user to switch between the two systems. I have included a link to the installation details for the P3. The P2, # 90885, will also work with both electric brakes and electric over hydraulic brake systems but the mode is selected...

  • How To Properly Setup a Prodigy P2 Brake Controller
  • I would recommend you start over with your Tekonsha Prodigy P2 Brake Controller # 90885 and go through the setup process again so that it will be properly setup. First step is to connect your trailer to your tow vehicle. Next, with the engine running, hold the manual lever full to the left and set the power knob to indicate approximately 6.0. Now you will want to drive your tow vehicle and trailer on a dry, level, paved surface and fully apply the manual lever. If the trailer tires...

  • Troubleshooting Turn Signals Not Working with Running Lights On on a Utility Trailer
  • First, check the trailer wiring harness on your tow vehicle with a circuit tester, like part # 3808, and make sure all of the functions are working correctly without the trailer connected. Make sure to test with the running lights on and off to be sure. If it is not working correctly you will most likely have to replace the taillight converter. If it is working correctly, turn your attention to the trailer. It does sound like a weak ground, or a short circuit issue, because when you...

  • Location of Brake Controller Port Under Dash of 2015 Toyota Tundra with Factory Tow Package
  • The brake controller port for the 2015 Toyota Tundra is located behind the section of the dashboard with the tow/haul button. To reach the connector you will need to locate the notch in the access panel in the center of the dash near the driver's side. Using a trim panel puller like # ALL648544, carefully pry the panel out and undo the locking tabs to remove the panel. You will find the mating connector behind this portion of your dashboard.

  • Troubleshooting Error Codes SH and OL on a Tekonsha Prodigy Brake Controller # 90185
  • The first error code, SH, you are seeing on the Prodigy Brake Controller, # 90185 (instructions linked below) means the brake wire sees a short circuit during idle condition. The second code, OL, indicates an overload condition during operation. For the first code, SH, the most likely problem is a pinched wire or at some point the wire insulation has cracked or been worn to the point where the copper wire inside is making contact with the trailer frame or another metal part.

  • Need Instruction And Operation Manual For Tekonsha Prodigy Brake Controller, # 90185
  • I am sending a link to the installation and operation manual for the Tekonsha Prodigy Brake Controller, # 90185. You will need to adjust the brake controller to fit your Ford Expedition application. The adjustments on the brake controller are for power and boost. The Prodigy brake controller will automatically level the sensor when it is installed. You will want to adjust the power to the trailer brakes before setting the boost. Also, it is best to warm the trailer brakes before setting...

  • Turn Signals on Boat Trailer Work, But Brake Lights Do Not
  • When you state that you never had to use a converter before, do you mean with this particular vehicle? That the brake lights worked with this trailer being towed by this vehicle before, but are not working now? Or do you have a new car, and you have hooked up the trailer connector and are finding that the lights on your boat trailer are not working correctly? Most trailers use what we call a combined lighting system. This means that the brake lamp signal and turn indicator signal is...

  • Trailer Turn Signals Both Blink at the Same Time When Right or Left Turn Signal is Turned On
  • If both turn signals blinking at the same time is a new problem that has occurred after the harness had worked fine before, there are a couple of possibilities that may be causing the issue. First, the easiest thing to check are the trailer connectors. You will be looking for any dirt or corrosion build up in one or both connectors (vehicle and trailer side). Clean them out if you find any dirt/corrosion and see if that helps. If you still have the problem, disconnect the trailer to...

  • Brake Controller Wiring Instructions for the Tekonsha Voyager # 39510
  • Depending on your vehicle year make and model, I will be able to provide instructions for wiring the Tekonsha Voyager brake controller. I have included the instructions for the Voyager, an FAQ article that features a basic diagram near the middle of the document, and an article on wiring a brake controller from scratch. The wires coming out of the Voyager attach as follows. The red wire attaches to the brake light switch wire that carriers a signal only when the brake pedal is pressed....

  • Setting Up the Tekonsha Primus Electric Trailer Brake Controller # TK90160
  • The initial set up involves connecting the trailer to the vehicle, starting the engine, and then fully engaging the manual override lever. While the lever is fully engaged, set the power wheel knob to 6. You will then start doing the driving/braking test and then adjust the power wheel accordingly. The power wheel does adjust the amount of power sent to the trailer brakes like you have said. More power (rotating the knob toward the front of the vehicle) will set the brakes more aggressively...

  • Tow Package Wiring Location for Brake Controller Install - 2016 GMC Canyon
  • According to my research, the 2016 Colorado/Canyon with the factory 7-way won't have a plug under the dash for installing a brake controller, but there will be bare tow package wires that you can wire the brake controller directly to. The tow package wiring is located behind the left kick panel, as you suspected. The wiring pigtail that came with your brake controller would wire up to the tow package wiring as follows: Black pigtail wire connects to red/green tow package wire (12-volt...

  • How to Get Separate Turn Signals and Brake Lights to Work on a Trailer
  • If your trailer has separate turn signals from the brake lights and you want them to remain that way, you will need to use a special converter. On the trailer side, behind the 7-Way, you will attach the Vehicle to Vehicle Taillight Converter, # 118158. On the 7-Way wiring, locate the wire for the left turn and brake and attach it to the yellow wire on the converter input side. Connect the wire from right turn and stop to the green wire input side. Ground the white wire to the trailer frame. On...

  • No Trailer Running Lights Troubleshooting on a 2012 Dodge Ram 3500
  • It sounds like you have narrowed the problem down to being on your 2012 Dodge Ram 3500 since multiple trailers have had the same results when connected to that vehicle. It sounds like the problem could be a blown relay on your truck since you have checked the fuses. However, the fuse you would be looking for should be in cavity J14 and will require a 20 amp cartridge fuse. We have seen this issue a few times and have seen some threads on the internet where people have had this problem...

  • Tekonsha Voyager Brake Controller Not Activating Trailer Brakes When Brake Pedal Is Pressed
  • Yes, we can help you test your brake controller and determine if the controller is bad or if there is a wiring issue that is causing the problem on your 2003 Ford F-250 pickup. Lets start with the easiest things first. Be sure that when you are testing the trailer brakes with the brake pedal that the vehicle is moving. The trailer brakes will not apply with the brake pedal if the vehicle is not moving because of the proportional sensor. The first thing I would check is the red wire that...

  • How to Convert a Trailer with Surge Brakes to Electric Over Hydraulic Brakes
  • You can convert surge brakes to an electric over hydraulic braking system. To do this, you will need an electric over hydraulic actuator and a brake controller. For an electric over hydraulic actuator, I recommend looking at the Carlisle HydraStar units. If your trailer has drum brakes, you will want part # HBA-10. If your trailer has disc brakes, then you will want part # HBA16. I have also attached a link to all of our electric over hydraulic actuators for you to check out your options. The...

  • Troubleshooting Dim Trailer Lights and Turn Signals Blinking Together
  • It could be a bad ground. You will have to check the ground points on each of the lights and on the trailer connector. The lights usually ground through the mounting studs. If there is any dirt, corrosion, or rust it could cause a bad connection. You will also want to check where the light bracket mounts to the trailer. I have included a video below on testing for a ground. If your trailer has a large amount of lights (like running lights along the sides) then the power draw could be...

  • Brake Controller Installlation- 2013 Toyota Tacoma
  • It is not difficult to determine if your Tacoma has the tow package wiring in place. If your Tacoma has the OEM 7-way trailer connector installed, the vehicle is indeed prewired for a brake controller. The # 3040-P wiring harness would plug into the connector located near the emergency brake pedal as shown in the photo I edited for you. Make sure the white ground wire with the ring terminal is grounded to bare metal under the dash. If you do NOT have the OEM 7-way, the plug for...

  • What is the Difference Between a 4-Way and 7-Way Trailer Connector
  • A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer brakes (requires a brake controller in the vehicle), and a reverse light or auxiliary power circuit. There are other types of connectors as well. I have included a link to our help article that shows and explains the various connector types.

  • Location of Brake Control Connector on 2004 Dodge Ram
  • Your 2004 Dodge should have the connector if the 4-pole connector was factory installed, but it might be a bit tricky to locate. Behind the emergency brake pedal on the firewall is a white junction box. The blue connector you are looking for is located above the junction box, and is sometimes actually pinned to the top of the box. You might need to give the connector a tug to get it free. The connector is sometimes hidden by the wires entering the top of the box, so sometimes you will...

  • How To Turn Off The Tekonsha Prodigy P3 Brake Controller # 90195
  • The Tekonsha Prodigy P3 Brake Controller, # 90195, does not have an on and off switch. It will go into sleep mode after several minutes of no activity. The power draw when it is in the sleep mode is so negligible that it will not discharge the battery. If you want the brake controller totally off, then you would have to unplug the connector from the back of the controller.
