• Trailer Brakes Work with Manual Override But Not with Brake Pedal on 2007 Toyota Tundra
• Any time that a brake controller works with the manual override but not the brake pedal that usually indicates a problem with the red wire connection or a blown stop light or CHMSL fuse (use the owner's manual to find the locations of fuses). You can use a circuit tester like # PTW2993 to test the red wire going into the brake controller. It should show power when you step on the brake pedal. If it does not, then it is likely a blown fuse but if the fuses are all good then there is an...

• Weak Brakes Using a P2 Brake Controller and BrakeRite EHB on a Boat Trailer
• First, make sure your BrakeRite EHB is wired up properly according to the included schematic. Any deviation from this can result in improper performance. If there is any corrosion at any of the connections or at a ground location, clean them and test the system again. To determine if the problem is the brake controller you can do some quick tests. You will need a multimeter, such as # PT89ZR. Sever the blue wire a few inches back from the brake controller. Then, with the controller set...

• Curt Trailer Brake Controller Only Works with Manual Override on a 2014 Toyota Tundra
• When a brake controller works with the manual lever but not with the brake pedal that usually indicates a problem on the red wire. The red wire is the input wire that tells the controller you are stepping on the brake pedal. The most common issue with the red wire is actually a blow stop light or CHMSL fuse. Use the owners manual to find the stop light or CHMSL fuse to check it. You will also want to test the red wire using a circuit tester such as # PTW2992. With the brake pedal pressed...

• Boat Trailer Lights Do Not Work with 7-Way to 4-Way Adapter with a 2005 Toyota Tundra
• There could be a problem with the adapter, or it could be pinned out differently than your truck. First, use a circuit tester like # PTW2993 if needed to test the 7-Way on the truck. If all the functions on the pins are working properly, you can eliminate the truck as the problem. If they are not working properly then that would indicate a problem on the truck side and you will want to check all the relays/fuses related to the tow package wiring. If the truck checks out ok, plug in the...

• Troubleshooting Trailer Running Lights Not Functioning
• To give you the simple answer to this- No. Your headlight being burnt out won't have anything to do with trailer lights not functioning. It's more likely that there is an issue on the trailer wiring, in this case. I would recommend checking your 2017 Toyota Tundra's trailer connector to make sure that you're getting power on all of the pins; you'll need a circuit tester like the # PTW2993 to complete this. I would also make sure that you've got a good ground connection on the connector....

If all the tail light functions then you know the issue is with the brake controller. The only thing you can really do to troubleshoot the brake controller is check the pins inside each trailer connector. If the pins are fine then...

• Troubleshooting Brake Output Pin on 7-Way Connector Putting out Constant 12-Volts
• I am guessing that either your trailer connector is wired incorrectly or there is a problem with your brake controller. The only pin on the connector that should show constant voltage is the 12-volt accessory circuit. The pin for the brake output should only show output when the vehicle brakes are applied or the override switch on the brake controller is activated. If you are getting constant 12-volt output on the 7-way connector, I would first recommend checking that the connector is...

• Adjusting Brake Controller in 2004 Toyota Tundra Causes Fuse to Blow
• It sounds like there is a short somewhere that is causing the fuse to blow. Which fuse is it meaning what is it for? Is it the fuse just for the brake controller or is it a general tow package fuse? I would start by checking the trailer connector on your 2004 Toyota Tundra (and the one on the trailer if it happens when towing). Make sure the connectors are clean and free of corrosion inside, where the wires attach, and outside on the pins. Also check as much of the wiring as you can and...

• What do the 4 Wires of a Prodigy Brake Controller Wire to on a 2010 Toyota Tundra
• I attached a picture that shows what circuits the wires of your Prodigy brake controller will connect to. The blue wire is the brake output circuit which carries the brake signal to the brakes, the red wire is the brake switch circuit that will have voltage when the brakes are applied, the black wire is the 12 volt power source which powers the controller, and the white wire is the ground circuit. The green wire you found will not attach to the brake controller. You could use a circuit...

• Troubleshooting OL Code on a Prodigy P2 Brake Controller on a 2014 Toyota Tundra Limited
• The OL code that you are seeing on your Prodigy P2 brake controller indicates that the brake controller is seeing an overload. Possible causes for this are a short on the electric brake wire or a poor ground connection. The first and easiest step is to inspect the trailer connector on the truck and trailer for any corrosion. If you see any green or white residue on the pins, that could indicate that corrosion has spread into the connector as well. You will want to repair or replace the...

• Tracing Intermittent Short In Trailer Braking System
• It sounds like you have an intermittent short somewhere in your braking system. The readings you are seeing are correct, because the short is intermittent. An intermittent problem can be very difficult to find, but your best bet is to physically examine the brake circuit on your trailer, from the connector all the way to the brake magnets. Look for a pinched wire, or cracked or worn wire insulation that would allow the copper conductor to intermittently contact the trailer frame and create...

• Voyager Brake Controller Does Not Light Up when Trailer is Connected to 2002 Toyota Tundra
• When a trailer is connected to the tow vehicle the Voyager brake controller # 39510 should show a green light. If it does not then we need to figure out if it is the controller or something else. First, to determine if the brake controller is the problem there are a couple of tests you can do. You will need a circuit tester such as # PTW2993 or a meter if you have one. Have someone sit in the truck cab and fully apply the manual override lever on the brake controller. At the same time...

• Troubleshooting Trailer Llights for 2004 Toyota Tundra
• If you already have a 7-way connector on your 2004 Tundra, then you would simply plug in the trailer. If you have the 7-way and the trailer is a different compatibility, you can use adapter # HM47570. If you have the factory connections but are missing the trailer connector, then you would use the Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package - 7-Way and 4-Flat Connectors # HM43385 or the Replacement Multi-Plug 7-Way and 4 Pole Trailer Connector # 20137. Both...

• No Power To Trailer Running Light Pin on Connector for a 2013 Toyota Tundra
• If you have power entering the running light wire just behind the trailer connector but not transferring though the plug to the running light pin then the trailer connector will need to be replaced for which you will want to use the 7- and 4-Pole Trailer Connector Socket part # HM40975. If you don't have power on the running light wire just behind the trailer connector you most likely have a blown fuse so you need to check the under hood fuse box on your 2013 Toyota Tundra.

• Low Voltage on Factory 4-Way Trailer Connector on a 2002 Toyota Tundra
• If the factory tow package wiring on your 2002 Toyota Tundra uses both fuses and relays then the issue could be a faulty relay. They can sometimes still allow some power to trickle back even if they are bad so that is one thing to check. There could also be a corrosion issue, ground problem, or wiring problem. If you are testing the pins on the 4-Way go ahead and test one of the wires going to the connector instead. If you get the proper voltage on the wire but not the pin then it is...
