- No Power To Trailer Connector With Tow Ready Custom Fit Vehicle Wiring # 118478 on 2007 Lexus RX350
- The correct trailer wiring harness for your 2007 Lexus RX-350 is the Tow Ready Custom Fit Vehicle Wiring, part # 118478. I would begin by making sure there is power going into the converter box by using a circuit tester, like part # PTW2993. Then, make sure power is coming out of the converter, if power is not coming out of the converter, it is possible that the unit is bad and would need to be replaced.
I would also inspect the wiring going to the battery and make sure that you have a...

- If you are not getting any power or signals, or limited signals to the 7-Way on the Tow Ready Custom Fit Vehicle Wiring, # 118243, then the problem could be with the fuses and/or relays that came with it. If not installed, they will need to be. If the truck already had some and you did not replace the factory ones with the replacements, the old ones may be bad and need to be replaced.
According to the installation details, which I have linked for reference, you will need to consult your...

- If you were to run the power wire of the Tow Ready Custom Fit Vehicle Wiring # 118578 to anywhere but the positive post of your vehicle battery you would void the warranty of the harness and could potentially damage the wiring of your RAV4 in the event of a short on the trailer wiring.

- If you have a Kat's Heaters Custom Fit Engine Block Heater # KH11484 that you referenced and it is causing the outlet of your vehicle to cut out then the problem is that the outlet is getting overdrawn either by the heater drawing too much amperage for the outlet to handle or because the heater has a short in the wiring of it and that's causing the outlet to short out.
I would recommend you go over the wiring of the heater looking for any cuts or other obvious signs of a short as that...

If your vehicle taillights failed after these harness installations this suggests a problem in the converter module itself or a short in the connectors/wiring between the vehicle and the module.

You will also want to make sure you are using the correct wiring harness. For a 2006 Jeep Commander with no factory package, you will need to use Tow Ready Custom Fit Vehicle Wiring, # 118408, instructions linked below.

- The first thing I would check is the fuse that came with the Tow Ready Custom Fit Vehicle Wiring, part # 118412. If it is not inserted all of the way or is blown, the converter will not work. Make sure the power wire for the converter is attached to the positive battery terminal via the in line fuse holder and fuse. No other 12 volt connection should be used. Make sure the white ground wire is attached to a bare metal surface.
If the fuse is blown you will want to check the trailer for...

- The Hopkins Custom Tail Light Wiring Kit for Towed Vehicles part # HM56009 which is a fit for a 2019 Ford F-150 uses the vehicle's trailer tow package ports for power. If you're having issues then I recommend checking the trailer towing fuses in the power distribution fuse box.
If you still have issues it will be a good ideal to rule out the umbilical or motorhome using a circuit tester. The only other thing that it could be is the integrated converter which would be the last thing to...

- The ModuLite in the custom fit vehicle wiring kit # 118552 is designed to draw it's power from the battery. As a result, it bypasses the electrical routes that are used by the wiring harness.

- The reason the Curt Custom Vehicle Wiring Harness you purchased is blowing a running light fuse is there is a short somewhere on the running light circuit.
I recommend thoroughly checking the brown wire on the connector back to the connectors on your 2006 Dodge Dakota looking for any spots where the wire is showing that could short, or for any other damaged sections of wire.
Any damaged spots will need to be replaced by splicing in # 16-1-1.

- If your 2001 Ford F-150 is equipped with a factory 4-Way trailer connector, the Tow Ready Custom Fit Vehicle Wiring, # 118242, should work. There are a couple of things you can check. First, there are a few fuses that need to be installed if you have not done so. I have included a link to the instructions below. The first few steps address the fuses.

- The first step that I would take to troubleshoot this issue is to sever the 12 volt power wire from the Curt 7 Way Adapter, # C57674, from the power wire of the Tow Ready 4 Way Wiring Harness # 118552. The 12-volt power wire from the Curt 7-way adapter should run directly to the vehicle battery via a 40-amp inline circuit breaker, # 9510. If you do not want to have to run another power wire to the vehicle battery, then you will want to install the 10-amp inline fuse from the 4-way harness...

- You will want to check the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56002 to ensure that it is working properly. To do that, you will want to use a circuit tester # PTW2993 and test that you have power on the wires before the converter and after the converter.

- It would be wrong to say they never go bad, but I am not familiar with one for a 2016 Toyota Highlander that has. This is a plug-in component, it is not hardwired/spliced into the electrical system. I suggest you simply unplug the custom-fit T-connector removing the Curt T-Connector Vehicle Wiring Harness, # C56217 from your system to troubleshoot.

If you did not use a wiring harness with a converter box in between the truck and the trailer connection then the break lights will not work because the Durango is on a five wire system and the converter sends the break light signal from the red wire on the vehicle side of the converter to...

- It is possible that there are separate left- and right-side tow package fuses on your vehicle. You will need to check your power distribution box to see if there are either missing or blown fuses.
Please note that the part you referenced, Tow Ready Custom Fit Vehicle Wiring # 118242, will not work with a factory 7-pole harness; it can only be used with a factory 4-pole harness. It will not work on Super Duty trucks; for a SD truck you need to use # 118243.

- If the Tow Ready Custom Fit Vehicle Wiring, # 118345, was working on your 1997 Ford Explorer but then suddenly stopped working, the first thing I would check is the fuse that came with the converter. The power wire should be connected to the vehicle battery via the fuse and fuse holder. If you find that fuse is blown you will need to replace it.
However, if there was a short on the trailer wiring, trailer side, or corrosion in the connectors on either side, it could blow the fuse again.
