If you installed the Curt T-Connector Vehicle Wiring Harness # C56217 on your Toyota Highlander, I recommend making sure that the white ground wire from the harness is securely attached to a clean, bare metal surface. A weak ground can certainly cause the low voltage you are getting at the connector. The running lights will require more power draw than the other basic light functions, so this would explain why the issue is only apparent with them activated.

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 Hopkins Plug-In Simple Wiring Harness for Factory Tow Package # HM11141825 you have is more than likely not the source of the issue.
Most likely it is a blown fuse or missing fuse on the driver's side underneath the steering column, and it is not a super uncommon situation for these fuses to be missing from the manufacturer.
This should be a 7.5A fuse labeled "IG1 NO.2"; consult the diagram on the fuse box for the exact location.
Check the fuse if there is one and see if it is... 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...
First you will need to determine if the lighting issue is in the vehicle side of the wiring or the trailer. A Test Light # PTW2992 will help you to test the 4-way plug. Simply connect the clamp side of the test light to either the ground lug of the 4-way for to a good chassis ground. You can then activate the headlights on your 2018 Toyota Highlander to check for power to the brown wire connector. This is the one closest to the ground terminal on the 4-way.

According to the troubleshooting section of the instructions the controller is telling you that the black power wire is not getting the 12 volts of power from the vehicle. This happens if the in line fuse or circuit breaker goes bad.
Double check that you are getting 12 volt power to the black wire on the controller. If there is no power to the black wire you will need to trace the wire to see where the power disconnects. If you are getting power at the black wire you may have a defective... view full answer...
On the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56217, since you don't have a blown fuse in your fuse box or the inline fuse, it is very possible the controller is bad. You will want to check functions with a circuit tester like # PTW2993 to confirm as the issue could be before the converter or in the four way harness.
First, I recommend checking the ground on the converter for a clean metal to metal connection. Then I would check the functions at... 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 wiring harnesses for the 2008 Toyota Highlander all have power that goes to the converter box so it is possible that the pins could have some power to them all the time. The power may be enough to light the test lamp but is probably not enough to power on the trailer lights. You can confirm this by plugging in a trailer. Curt wiring harnesses have been known to do this but I have not heard of this issue on other brands.
You will also need to make sure that if your harness requires... view full answer...
The # 322-RDJ-2K Ultimate Trailer Jack can be rotated in any direction as long as one of the holes is facing forward. So rotating the jack will not be a problem.
As for aligning the holes, I would not recommend modifying the jack in any way, since that can void its warranty. If you are having trouble mounting the jack to the trailer I recommend changing the mounting holes in the trailer so they match the holes on the jack.

The Rhino-Rack RVP Roof Rack for Fixed Mounting Points - Vortex Aero Crossbars - Aluminum - Qty 2 # RRRVP37 should have a little flex and play but what you are referencing as a concern sounds excessive. I recommend un-installing the crossbar and foot and looking for where that "play" may be coming from. If the lock washers on the fit kit and the tower are flattened, then I would need to see a visual of the movement to further help but replacement may be necessary. I've attached a couple... view full answer...
Trailer weight distribution/sway control systems like Curt # C17062, which uses the friction bar type anti-sway, and even the integrated anti-sway systems built into other weight distribution systems like the Equal-I-zer # EQ37120ET will generate some noise. Since they use friction to control/prevent sway some noise is inevitable, even when everything is set up correctly.
Depending on the particular system and driving conditions this noise can be enough for you to hear it in the vehicle.... 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 easiest way to determine which wire is your reverse light wire so you can install the Universal Installation Kit for Trailer Brake Controller # ETBC7, is to go to the rear of the vehicle where your taillights are located and pull the housings off of the vehicle to have access to those wires.
From here, you're going to want to turn the car on, engage the emergency brake, and then shift the vehicle into reverse.
At this point your housing should be off of the vehicle, and the wires... view full answer...
In order to troubleshoot your 2022 Toyota Highlander wiring installation you will need some tools to assist you. You will need a 12V circuit tester. I recommend the Cordless Circuit Tester, part # PTW2979. In addition, you will also need basic wiring tools, electrical tape, a wire stripper, dielectric grease, and wiring fasteners. Troubleshooting your trailer wiring can be very intensive.
This can be caused by a number of issues. If you have a plug in harness, it may be for models with... view full answer...
I have not seen any customer feedback stating that the K-Source Universal Towing Mirrors # KS3891-2 have folded in when a semi truck passes by in the opposite direction, although I can see a big rig doing so if the tow mirrors were not completely tightened and secured to your factory mirrors.
If the tow mirror itself folded in then I would make sure the screw on the back of the tow mirror is tight to reduce movement - do not overtighten since the housing is plastic. Also make sure that... 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.

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...
If your trailer lights just recently started malfunctioning, I recommend that you start by checking to make sure that you don't have a blown fuse or a bad relay in your 2008 Toyota Highlander. You will want to check all of the fuses and relays that relate to the tow package.
If all fuses and relays check out to be fine, I would then check the grounds on both the Highlander and your trailer. You will want to check to make sure that the ground wire is secured tightly to a clean metal surface... 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...
