The issue with the Draw Tite hitch part # 75726 not lining up with the holes on the vehicle like your 2010 Toyota Highlander is actually due to the hitch getting bent in shipping and not a design flaw. Unfortunately hitches are somewhat heavy and awkward to handle so shippers don't always handle them with enough care and the brackets can get bent and cause this issue. The hitch can be bent back and as long as there isn't creases or flaking paint you wouldn't have any problems. view full answer...
Using a tester like Digital Multimeter with 42" Long Test Leads - LED Display # PT89ZR I would test the wiring starting at the factory plugs/connections and work your way back seeing if there is a short or bad ground. As well as checking all of your fuses just to be certain.
If that doesn't work you can either have a dealer check it out and charge you an arm and a leg to fix it or you can bypass the factory tow package completely with the ZCI Circuit Protected Vehicle Wiring Harness w/... view full answer...
It sounds like you have a short on your boat trailer wiring harness on the left side. When you are testing the lights on the trailer with just the 12-volt battery you are eliminating the ground on the trailer frame, so the lights will show that they are all working on the trailer.
I would recommend rewiring the trailer with the Optronics 35 ft. Wishbone 4-Way Trailer Wiring Harness # A35W42B. This harness has the 4-way connector with a 5-wire system. This will eliminate any possible shorts... view full answer...
If the tires on your tandem axle trailer are leaving the ground during travel when it's empty there are a couple of things I recommend looking at.
The first thing that comes to mind is the trailer's suspension. A stiff suspension can definitely create a rough ride with a lot of bounce especially when the trailer's completely empty. I recommend making sure that the leaf springs are appropriately rated for the trailer and not way over capacity (if you have 3,500 pound axles the springs'... view full answer...
In order to test the powered module of the Curt T-Connector Vehicle Wiring Harness # C56217 you will need to use a circuit tester such as the Cordless Circuit Tester # PTW2979 and test the wires going into the module, and then the wires coming out of the module. If there is power going into the module, but none coming out, that means it could be faulty and needs to be replaced. This harness does have a 1-year warranty. A converter will often go out due to a short in your trailer wiring,... view full answer...
Is this a brand-new installation, or has the T-Connector been installed for awhile?
As a first step, I would recommend trying a different trailer, if possible. This will help determine if the problem is in the trailer wiring or that of the vehicle.
If everything works fine with another trailer, then you have confirmed that the problem is in the trailer wiring. If the lights on the second trailer do the same thing, you have confirmed that the T-Connector is faulty and should be replaced.... view full answer...
In order for the # ETBC7 to work properly you have to make sure that it is grounded to the vehicle frame at a place that is clean and free of corrosion. The light functions should all work if you just have the 4-Way plugged into the ETBC7 and it is properly grounded. Then when you hardwire in the black wire for 12 volt power, blue wire from a brake controller, and purple wire for reverse lights, those will all start working. but nothing will work or work properly unless the white wire is... view full answer...
You're likely on the right track. If your fuses keep blowing out, this is a sign that there is a short somewhere on the system-most likely on the running light circuit. Since you're saying that the trailer has all new wiring-if this was something you installed I would recommend re-checking your wiring to make sure that there isn't an exposed wire (cut, damaged or otherwise) touching the frame of the trailer. The ground wire on the trailer should be checked to make sure it is secured to... view full answer...
The 4 pin connector used to install the # 56042 can be in a few locations which does make the install a little more interesting. I am glad you were able to find it.
I would verify that you put the fuse in the correct location. If that doesn't fix the problem I would verify that the connector of the # 56042 is making solid connection with you tow vehicle and that the fuse didn't blow while in the wrong slot.
I attached an install video that shows a very similar product being installed... view full answer...
SAE is correct, it stands for Society of Automotive Engineers. The SAE followed by numbers and letters is a lens rating.
LED lights are usually sealed or the LED module itself will be sealed. They can burn out but it would either take a long time or an event such as a bad short to cause them to burn out.
You might actually have a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function... view full answer...
As you have checked all the trailer grounds and updated the lights to LED, the only other thing I can suggest before replacement will be the ground on your Highlander. It is odd that the issue only happens some of the time, so it could be this as well.
If this ground looks good though, then your Tekonsha # 22119 has indeed gone bad and will need to be replaced. Especially since nothing else has been changed. view full answer...
There are some things you can do to determine if the issue is on the harness, # 118413, or somewhere else. First, make sure that the harness is grounded to a clean metal surface. There cannot be any paint where the harness is grounded. Also, if you are using a factory grounding point that is already occupied by 1 or more items then I recommend moving the harness ground elsewhere.
Next you will want to test the wires going into the black converter box and the wires coming out. Use a circuit... view full answer...
That is a very interesting situation that you're in. I do have some things for you to check to help make sure you are able to safely tow your trailer, but unfortunately there are no aftermarket suspension enhancement options to help level out your 2018 Toyota Highlander.
From what you stated it sounds like you are pretty mindful of the tongue weight (TW) of your trailer but it still doesn't hurt to go back and double check what your TW is when the trailer is fully loaded. A portable TW... view full answer...
The first thing I would check is the small fuse that is part of the converter box wiring for harness # 118449. If that fuse is loose or blown the whole harness will not work. And if it is blown it is possible that a short on the trailer caused it to blow and until that short is found and fixed it would just keep happening.
If the fuse is not blown then the converter box itself could have blown and the harness would not work. You would need to replace the wiring harness. You can also check... view full answer...
The most likely case is that the box has kicked the bucket and will need to be replaced. Since you are not getting power to the right turn/brake pin on the 4-Way, test the corresponding wire on the input side leading into the converter. If there is no power there either than you will want to check the turn signal fuse or relay for the vehicle. Find it using the owners manual.
You can also trying moving the ground wire to a different location.

Thank you for your recent purchase from etrailer.
There are several possibilities for the trailer lighting issue you are having. First, I suggest you test the trailer that has the 7-way connector, either by connecting it to another vehicle with a 7-way or by directly testing it with a 12V battery. You can apply 12V power directly to the trailer connector's pins to see if the lights function. If they do, then you know the problem is upstream of the trailer; if they do not you need to troubleshoot... view full answer...
If you have a factory plug on your 2006 Toyota Highlander then these circuits will be protected by fuses and relays built into the factory fuse box located under your hood. In order to be sure you are looking in the correct locations you will need to either look in your owner's manual for these locations or there will be a diagram printed on the underside of the fuse box lid with this information for you. If you do not already have the trailer connector portion of the harness then I recommend... view full answer...
The factory trailer connector port for the 4-way connector your purchased for your 2021 Toyota Highlander XLE with the Factory Tow Package is below the bumper on the driver side of the vehicle.
Since your Highlander has the factory tow package the connector should be active. Since you are not getting any power to the connector I recommend checking the engine bay fuse box for any missing fuses. The owner's manual I was able to find for your vehicle does not have a breakdown of the fuse... view full answer...
Since you have tested the trailer with a different vehicle, and everything seemed to work okay, it would seem that you have ruled out the trailer as being the problem.
You have tested the trailer connector, and have found that each pin on the connector is showing power when its function is activated, which would usually rule out the vehicle.
I would first suspect the ground connection for the trailer connector on the Highlander. Trace the white wire and locate the point where it grounds... view full answer...
On the Curt Venturer brake controller # C74VV the LED light should glow red all the time when no trailer is connected. If the light is flashing red when you step on the brake pedal then the controller is sensing an overload or short circuit.
You mentioned that you have not towed the trailer in awhile. What usually happens is corrosion on or inside of the trailer or vehicle side connectors. Make sure the trailer and vehicle side connectors are clean and free of corrosion inside and out.
