Video Transcript for Trailer Wiring Harness Installation - 2007 Lexus RX 350

Today on this 2007 Lexus RX350 we are going to be installing the 4-pole harness part number 18002. The Lexus that we are going to show you today has a unique situation to it. On our website we indicate the wiring for the Lexus is going to be the modulite part number 119176. This particular Lexus does have a factory installed tow package that we are going to be able to tap into so we are going to show you how to locate that. The port is located in the rear cargo area of the vehicle underneath the flooring over on the driver side. We are going to need to remove most of this interior section. There is a particular order of operations that we need to abide by to get all of the components out. 00:38

We are going to start by removing the forward most cargo door. We need to pull back the facing at the front section first. There are push rivets that are holding that in place so just pull it up. We need to unscrew the hinges that are holding the flooring into place. There is one screw per side for these hinges. We next remove the forward most cargo storage area. There are two push rivets holding this into position. One on the driver side and one on the passenger side. We are going to be using a rivet removal tool. We need to slide it underneath and just pry it up. 01:11

Next we are going to remove the front storage compartment. To access it we need to release the two coverings and there are buttons at the rear threshold to do that. Again, we have got two push rivets holding it in place. One on the driver side and one on the passenger side. Next we will remove the driver side floor covering and there are actually four bolts holding it into position, two here at the rear side and two at the forward side. Next we will remove the rear threshold piece. There are two push pins that are holding this into position. One on the driver and one on the passenger side. When removing the threshold piece you need to watch the releases for the cargo buttons. Make sure you clear the releases for the cargo doors. When you get the threshold piece to release you need to press these in. Finally we want to remove the driver side storage compartment. We have got two fasteners holding it in position. One push pin here and one here at the inside of the cargo area. 02:22

With all of those components removed, if we look at the main wiring harness feeding the tail light assembly on the driver side, there is a port located right here and that is our tow package port that we are going to be tapping into. Unfortunately this time the manufacturers do not offer an after market plug-in for this port. So what we are going to do is cut this end off and we are going to wire our wiring harness directly into it. Before cutting the end off I am going to remove the fuses activating our tow package so that we do not shorten anything when we cut the wires. You can locate this fuse underneath the hood in our accessory fuse box. If you remove the lid and look at the top side, it is labeled towing 30 amp fuse. We will put that back in when we are finished wiring in our 4-pole. Then back at the port we will cut the wires. The 4-pole harness comes with quick splices to make our connections with. However I am going to use some standard butt connectors. We tested previously to find out which wires carry which function. The green is our right turn, right brake signal. Yellow is our left turn, left brake signal. The blue wire is our running light lead and the white is the ground. It is pretty similar to the wires that we have got on our 4-pole harness. The white is our ground, the yellow is our left turn, left brake. Green right turn, right brake, and the brown is our running light lead. 03:52

We want to strip back some of the jacketing on each one of the wires. With our wiring stripped back we just want to apply the butt connector. We will the wire into one end and then we will crimp that down. Take the adjoining wire and slide it in and crimp it down as well. Then we just want to tape up those connections. Then for storage of the 4-pole we have two options. We recommend that you leave it inside the vehicle. Store it in the storage compartment over here and then just pull it out the rear cargo door whenever you want to use it. However if you do need it underneath the vehicle permanently there is a grommet there right below the connector. You can just put a splice in that, route the 4-pole through there and then you can leave it underneath the vehicle permanently. From there we just want to put our fuse back into position and reinstall our flooring and then our installation will be complete. With the interior reinstalled we will show you how you can store your 4-pole. When you want to use it again just pull it out the rear door and you can close the door on it. You do not have to worry about it being pinched. The weather stripping at the rear will prevent that from happening. You can see I can still move it side to side freely. With that, that will conclude the installation of 4-pole part number 18002 on a 2007 Lexus RX350.

This trailer wiring matched up exact with the auto wiring. I was able to install in very short time. 656955

Hitch and install were simple and easy, as well as the wiring harnesses to the trailer. 632015

Just finished installing hitch and wiring on my Lexus rx350. Everything went in perfectly and the video was a great help on the trailer wiring. Even showed how to disassemble interior panels to reach loom 408498

I gave ETRAILER and the trailer hitch five stars. The product is of very high quality and the customer service received was awesome. Installed the heavy duty hitch in less than thirty minutes. It was a custom fit for my 2009 Lexus 350RX. The wiring harness for less than $10 was a perfect match since my Lexus was equipped with a towing package. Shipping was SUPER FAST AND FREE!!! 398112

I ordered a more expensive harness initially. I then found that my Lexus was prewired for a harness and needed only this one. Only bummer was I had to pay $11 to ship the other one back and this one did not qualify for free shipping. So my mistake cost me an extra $15. 374460



- 18002
by:

Trailer wire received was as expected however there is one part that could be better. The 4 box type 3M wire connectors that come with it are not the right connectors for this application. When connecting the 4 wires the box connectors are all on top of each other and create a large "bunch". The etrailer "how to video" shows the use of butt connectors which is a much better application. The "how to" instructor acknowledges the 3M connectors that come with the wires but simply says he is going to use butt connectors. So, why not include butt connectors in the simple wire kit? Otherwise all is well and trailer lights work fine, thanks etrailer for your good service. 273966

Purchased this plus 18144 mounting bracket for new installation on my 2007 Lexus RX350. Lexus SUV was advertised as having "towing prep package", a $160 option, installed but it wasn't clear if that package included the proper wiring connection under the floor for this product. After digging down (per your excellent video for this vehicle), I found everything as hoped for. Installation was less than 45 minutes including cargo area disassembly and reassembly. Mounted the mounting bracket on plastic surface under the bumper - drilling was easy and mounting appears to be secure. Finished off installation with 30512 flat cover LED tester. All in all a very clean installation. BTW, used 12 inch plastic ties to dress wires under the car so that nothing droops done. My wife is pleased - which goes a long way to confirming the aesthetics of the installation. Thanks for the great videos and products. 146869

  • Ways to Install New 4-Pole Trailer Connector
  • Four flat trailer wiring, also called 4-pole wiring, uses four wires and pins configured as shown in the linked photo of a trailer side 4-pole connector. The one pin that is different from the other three (on both trailer and vehicle side connectors) will be the ground pin and this usually has a WHITE wire that will ground to a clean bare metal spot the trailer frame with a ring terminal. The next pin is for the running light circuit and this typically uses a brown wire to activate...

  • Trailer Error Message with Hitch Light on a 2018 Ford Escape
  • I do not believe that there is an issue with your 2018 Ford Escape or there is an issue with the Oval LED Brake Light Trailer Hitch Receiver Cover part # CR-017. Unfortunately, the electrical systems in newers cars today are very complex and they do not like when aftermarket accessories are used. The issue you are having is that the vehicle thinks there is a trailer attached when you have the hitch light plugged in. The power draw from the hitch light is not comparable to that of a trailer...

Harnesses # C55563 and # 118478 can still be used, and will provide higher current with protection for the car's wiring I've added a link to a video review of this part being installed on an '07 RX 350 for you to check out which will be the same as your '09.

  • Troubleshooting Trailer Brakes Not Working When All Other Trailer Functions Work Properly
  • I suggest first disconnecting the plugs and reconnecting them because sometimes you will get all the functions except one and the issue is just the clip not being seated completely. If that isn't the solution, then using an incandescent circuit tester like the Circuit Tester # PTW2993 to test your brake signal wire when the trailer is not connected. In a typical four wire flat system, this will be the brown wire. Test it for signal at the vehicle. if it doesn't work there, check the...

  • Troubleshooting Running Lights Not Working On Trailer When Hooked To 2012 Chevrolet Silverado
  • Since you said the problem exists for two different trailers, the problem will be found in the truck wiring. You said you checked all of the fuses and they are okay and then you said you used a circuit tester and found the running light circuit is not working. There should be a large fuse box on the driver side under the hood and on the fuse legend the fuse you can check out is titled 'Trailer Park'. This is a 15 amp fuse and can be the source of the problem. If you find the fuse is...

  • Recommended Trailer Wiring Harness for 2003 Toyota Tacoma
  • To provide a trailer wiring harness for your 2003 Toyota Tacoma, you'd need the Draw-Tite taillight converter, part # 118379. The wiring harness would plug inline between the taillight assemblies and the vehicle wiring harness, providing a plug and play connection that won't require any cutting or splicing. I've linked you to an install video and the installation instructions.

  • Installing Trailer Wiring Harness on 2009 Lexus RX350 with Factory Tow Package
  • If you are using harness # 18002 then you would ground the white wire to a clean, bare metal surface. The white is the ground for the harness. The wires that you are tapping into on the vehicle will use that ground and it should still work. It is possible that the ground on the factory harness is tucked up further towards the front of the vehicle for some reason so you will want to cut back the covering/loom to see if there are more wires. The ground may not be white on the vehicle harness....

We offer the Tow Ready Custom Fit Wiring, # 118551, which is a powered unit and requires you to run a power wire to the battery, which helps isolate the vehicle wiring from any short circuits that might occur in the trailer wiring. This harness installs inline with the taillight wiring, and other than having to run the power wire, is a plug-and-play install. A...

  • Troubleshooting Trailer Lights Not Working After Installing Harness 118335
  • The issue is obviously the wiring in your '98 Chevy Express since the trailer lights work fine on other vehicles. Start your troubleshooting by using a circuit tester such as # 40376 to test the connector on your van after disconnecting it from your trailer. Check the wiring going into your harness from your tail lights to see if those wires are carrying the correct signals; if not, since Wiring Harness # 118335 is a plug-in harness, check to see if your connectors are flush and that there...

  • Is there a European 7-Way to US 4-Way Trailer Wiring Adapter for a BMW
  • Bascially, there is no easy way to convert the European 7-Way to a US 4-Way. We do not carry any kind of adapter that you could use. You are left with 2 options. First, you would install a separate wiring harness which would be the easiest. Or, you could attempt to fabricate an adapter. You would need to use a converter, # RM-732. The red wire on the input side would attach to the brake light wire on the vehicle wiring. The white wire grounds to the frame. The yellow wire will attach...

  • Trailer Wiring Connector for 1999 Chevy Express Van
  • Attempting to wire a 4 pole like the # 18002 into the taillight system of your 1999 Express won't work, as you've found. The 1999 Express uses what is referred to as a separate or a 3 wire taillight system, where the running lights, turn signals and brake lights are carried on 3 different circuits. If your van had a 2 wire system, where the running lights were on one circuit and the turn signals and brake lamps were combined on the same circuit, the 18002 would've worked fine, but since...

  • How to Keep CR-017 Brake Light Hitch Cover From Blinking w/ Turn Signals
  • There IS a way to get the # CR-017 to operate only with the running lamp and brake light without blinking with the turn signals, you'd need a 4-pole trailer end connector, part # 18004, a vehicle end connector, part # 18002 and a vehicle to vehicle taillight converter, part # 118158. You'd wire it together as shown in the provided photo. You'd essentially be making a large adapter that would isolate out the brake signal.

  • Installing Wiring Harness on 2009 Lexus RX350 with Factory Tow Package
  • The RX350 with the tow package is somewhat of a rarity. Since your Lexus has the wiring port in the rear drivers side cargo area, I would recommend using a circuit tester like part # 40376 and check to see if that port is active. Activate the left turn signal, and probe the wires until you locate the one that makes your tester light. Repeat this procedure to identify the right turn and running light circuit. I would recommend also testing the right and left turn wire on the port to make...

  • Installing a 4-Pole Trailer Connector at Rear of 5th Wheel for Towing Boat Trailer
  • The Curt # 13703 would work fine for you. To install a 4-pole connector at the rear of your 5th wheel, the easiest option would be to tap a 4 pole vehicle end harness like # 18002 into the taillight circuits of the fifth wheel. I do have a caveat or two to share, however. -Keep in mind that towing a trailer behind another isn't legal in many states, and from a safety standpoint it's something we don't recommend. -You'll need to determine if the tow package of your Silverado has...

  • Brake Controller Installation for Motorhome with Air Brakes
  • A brake controller like the Tekonsha P3 will work just fine with the air braking system on your motorhome. The controller will get its input from the brake stoplight switch, which tells it when the brakes are being applied. If there is a 7-way trailer connector at the rear bumper, there might be a connector located under the dash that the controller would simply plug into. You would need to contact the motorhome manufacturer for more information about this. If you do not have a...

  • Trailer Wiring Harness Recommendation for a 2005 Saturn Vue
  • The recommended trailer wiring harnesses for your 2005 Saturn Vue are ones with converter boxes like the part # 118418. That being said our installer was able to find a way to wire in the part # 18002 to a 2004 Vue similar to yours. This isn't the ideal solution, but it would work if you used the install video as a guide. I attached install videos for both harnesses for you to check out.

The wiring harness that is recommended for your vehicle is the Tow Ready Custom Fit Vehicle Wiring for the Lexus RX350, item # 118478. This harness installs inline with the vehicle tail light connectors and requires a power wire, that is run to the positive post of the vehicle battery. This...

  • Trailer Wiring Harness Converters Keep Failing when Installed on a Semi Truck
  • You mentioned that the truck is a semi truck. Does it run off of a 24 volt system? If so then that would be why you are having bad luck with converters. Trailer LED lights run off of 12 volts just like incandescent lights but LEDs draw much less amperage so that is the big difference between the two types. LED lights can run off of a lower voltage but often times they appear dimmer. We have a converter # 119192 that is rated for 4.2 amps for brake lights and turn signals and 16...

  • Attaching Ground Leads from Trailer Tail Light
  • No Problem! Each ground wire would simply ground to the trailer frame. You can use a self tapping screw, and make sure that the area you are attaching the wire to is not corroded. What you are doing is using the trailer frame itself to carry the ground from the light fixture up to the grounding point on the trailer tongue.
