Trailer Wiring Harness Recommendation for a 2010 Toyota Corolla Towing Trailer with LED Tail Lights
Yes, the Curt Custom Fit Vehicle Wiring # 55542 that you referenced would work on your 2010 Toyota Corolla and work well with the LED tail lights of your trailer. LED tail lights draw considerably less than incandescent bulbs so they should work well with the # 55542 since this harness has a 3 amp per circuit limit for the stop/turn lights and 7.5 amp limit per circuit for the running light circuit. I attached installation instructions and an install video for this product also.

Can a 4-Way Trailer Wiring Harness be Installed on a 2013 Nissan Frontier with Factory 7-Way
All you will need to use a 4-Way and keep the 7-Way also is a simple adapter like # PK12716. You will not have to worry about hardwiring in anything or losing out on the use of the 7-Way. If you were to install a replacement factory 4-Way you would not need any additional relays. The ones that work with the 7-Way also work with the 4-Way. If you choose to install a 4-Way you will have to disconnect the 7-Way because they plug into the same locations.

Troubleshooting Left Hand Turn Signal Malfunctioning on Trailer Plug
Checking to see if the fuse is intact and the power to it and behind it is definitely a great start to determining what the issue might be why your left turn signal is not working properly. Since this issue is isolated to only one function I am leaning to towards it being a broken connection. First I would check all connections points and make sure that the wires are secure and free damage. Look for any corrosion or wire damage within the connector, as well as the wires leading to the conne

Compatibility of Curt T-Connector for 2006 Acura MDX with Wishbone Trailer Connector on Trailer
If your trailer uses a 4-pin connector that has five wires leading to it, your trailer uses what is called a wishbone harness. The running light circuit separates at the connector (rather than separating further down the line) with one leg running down each side of the trailer. The Curt T-Connector # C55336 for the Acura MDX will work great with this type of trailer connector, as long as it is indeed a 4-pin connector. No adapter will be necessary.

Finding the Third Brake Light Wire on a 2013 GMC Sierra 2500HD for a Camper Shell
There may be a wire loom under the truck, above the spare tire with some tow package wires in it. If you cut back the loom often times there will be 2 additional wires. The Light Blue wire provides a lead for a camper shell brake light. The other, a Light Green wire, is for the reverse lights. To make sure you have found the correct wires, use a circuit tester like # 3808 to test the wires. If this wiring is not present, to add a third bake lamp you would need to tap into the turn signal c

Parts Needed to Install 7-Way Trailer Wiring on a 2012 Subaru Outback Wagon

It sounds like the problem could be the converter box of the T-One Vehicle Wiring Harness # 118412 if the connections are good and the ground is good. The best way to test the box would be to get a circuit tester like the part # 3808 and test the wires going into the box and then out the other side.

Trailer Right Turn Signal Does Not Work When Connected to 3 Different Vehicles
It certainly does sound like a short on the trailer that caused some problems, but I would not rule out the possibility that it is just coincidence and that there is an issue with all the vehicles in some way, shape, or form. If the trailer draws more that 2.1 amps per side for turn/brake lights then that would cause the converter to blow. On the trailer, make sure its connector is free of corrosion.

Trailer Wiring Stopped Working After Turning On Hazard Lights on a 2006 Nissan Titan

But with both blinkers going on at the same time, the power draw increases and that could have caused a fuse or relay to fail. For relays you could use # C57000.

As long as your vehicle is a 1992 Toyota Pickup and not some other model like a T100 pickup, you have the correct wiring harness. There are two possibilities for the symptoms you are describing. A ground issue or a short between the taillight circuit and turn signal circuits. Because there would need to be a short between both the left and right turn signal circuit and the ground I would think that would not be the issue, unless the converter box has been shorted out. Since you have already c

Left Turn Signal On 7-Way Trailer Connector is Not Working
It is possible that there is a blown fuse or relay related to the tow package wiring that is causing the problem. Use the vehicle owners manual to find the locations. It is also possible that there is a break in the wire somewhere. You will need to use a circuit tester like # 3808 if needed to test the wire as you work your way forward on the truck. If the right side stop light also does not work it could be a blown stop light or CHMSL fuse. If the turn signal function works on that same

Parts Needed to Convert a 4-way to a 5-way for a Honda Odyssey Towing Surge Brake Boat Trailer
You are going to need to install a Adapter 4 Pole to 5 Pole # 20036. This product will plug right into your 4-way and then you will run the blue wire from the adapter to your reverse light circuit and then you will have a fully functional 5-way that will allow the trailer brakes to release when you reverse your trailer.

Fuse Location for Trailer Wiring Harness 118255 for a 2010 Lexus 450h
I spoke with my contact at Tow Ready about wiring harness # 118255. He stated that the build sheet for he harness only shows one fuse included. However, it is possible that you may need to install a fuse in a fuse panel to make everything fully functional. Before doing this, you will want to determine if the wiring harness is functioning by using a circuit tester like # 3808 if needed to test the 4-Way while someone runs through the lighting functions on the vehicle.

Trailer Lights Not Working After Install Wiring Harness on a 2014 Kia Sorento
To determine if the problem is with the vehicle or the trailer, first disconnect the trailer from the vehicle. Then use a circuit tester like # 3808 or the one that came with # 119147KIT. Test the pins on the 4-Way using the circuit tester while someone sites in the vehicle and runs through the functions. If all the signals are correct on the 4-Way when you test it then the issue is on the trailer. But if the signals are not correct then there is a problem with either the wiring harness, inst

7-Way Trailer Wiring Harness Stopped Working On a 2011 Honda Pilot
The first thing I recommend doing is checking the vehicle side connector for dirt and corrosion build up at the 4-Way. I had a friend that had this problem. The 4-Way had enough corrosion in it to cause the lights not to work. After clearing it out, it worked fine. You could use a circuit tester such as # 3808 if you do not have one to test the wires at the back of the 4-Way to determine if the signal is getting through to that point. That would confirm a problem with the plug, most likely co

How to Adapt a 6-Way Vehicle-Side Trailer Connector to a 7-Way
Since your vehicle already has a working 6-way connector for your trailer that uses electric brakes, you will not need to install any additional fuses or relays in order to change to a 7-way connector. The simplest and most cost-effective option is to use an adapter to convert your 6-way to a 7-way.
