Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Video Transcript for Tekonsha Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 118412 Review

Today we'll be reviewing part number 118412. This is Tow-Ready's T1 vehicle wiring harness with the four-pole flat trailer connector. This is going to provide a four-way flat trailer connector at the back of your vehicle to help power your trailer signal lights. This is going to be compatible with five-pole, six-pole and seven-pole adapters. Those are going to be sold separately. This system is great because it connects very quickly and easily. All you have to do is locate the connection points in the rear of your cargo area, plug in the T connector.

It's going to be the tail light assemblies, so you're going to plug in the T connectors. Then the red wire is going to be the hot lead, so you're going to need to connect the red wire to the black wire using the included butt connector. Then you're going to run the black wire to the car battery. You're going attach the ring terminal and you're going to connect it to the positive post on your battery. Then there's a fuse holder that you need to connect as well, and the included fuse goes into that holder.

Once you make that connection, you should be all set to go. It's going to include the module light to help insure that your vehicle's wiring matches that of your trailer's. The power module connects directly to the battery to avoid overloading the vehicle's electrical system. That's where that hot lead is coming from. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuit, so you do not have to worry about that. The entire unit is constructed of 16-gauge bonded wire, except for the black one. I believe that is going to be 12-gauge wire.

The four-pole is going to come with a nice dust cap that connects over the connection point to help protect those connection points from the elements. Also in the little bag you're going to get eight zip ties to help clean up your install look so you can secure the wiring as needed and get it up and out of the way. You're also going to get some dual-sided tape. It goes on the back of the module light. That way you can connect it to a nice flat surface. You're also going to get, again, two butt connectors, the ring terminal, the fuse holder and the included fuse.

You're going to get a self-tapping screw. That way you can use it right here to make your ground connection at the rear of your vehicle. When it comes to amperage, the stop and turn lights are going to have 2.1 amps per circuit. Your tail lights are going to be 4.2 amps per circuit. When it comes to installing this, this is a custom-fit T1 connector. It's going to plug directly into your vehicle's wiring harness. That's going to be located behind the driver's side and passenger side interior trim panel and the rear cargo area of your vehicle. Once you've plugged in the T connectors, all you have to do, again, is run that hot lead to the car battery, connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse. Keep in mind that it is recommended that you use a small amount off grease on all electrical connections, the plugs on your automobile and the four-pole connector itself. That's just going to help prevent corrosion. That's going to do it for today's review of part number 118412. This is Tow-Ready's T1 vehicle wiring harness with the four-pole flat trailer connector. .

Installed a trailer hitch and light wiring kit on a '07 Rav4. The weld nuts were rusty and dirty. This caused me the most problem. The instructions were easy to understand and very helpful. Had to do a little bending to get the holes to line up. This is common for a weldment. The electrical instructions were excellent and easy to understand. Somewhat difficult to route the wire to the battery. Easier if I had a hoist. Do have to use the shifter over ride for some reason. I suspect something in the electronics. Dealer should be able to help. 209672

Wire harness was relatively easy to install, thanks to the YouTube tutorial. Had some trouble with the butt connectors, but I suspect it was mainly due to my complete lack of experience with using them. I cannot overstate the importance of the YouTube tutorial. It, not only helped me install in easy to follow steps the wire harness, but it gave me the exact part that I needed to complete the project. This coming from a complete novice, without the help of any expert outside of the tutorial on YouTube. Thank you guys!! 131995

One year follow up. Purchased etrailer hitch and wiring harness for Toyota Rav4 2011. Some difficulty with one hitch screw. Didn't remove the rubber exhaust pipe support as instructed. It would have been very difficult to re-install. Bought a torque wrench and torqued all screws as instructed, except the fourth. This fourth screw was not very accessible and I was to torque it to almost the full torque with the limited access I had. The instructions want you to remove the exhaust hanger, and it would have been nearly impossible for me to re-install it. Installed the wiring harness... Partially. I only installed the left side. The disassembly for the right side would have been quite difficult, and unnecessary for me. I stacked the left and right connectors and I got trailer brake lights. Not a perfect installation. And I'm considering continuing the installation to install to both sides. We only drive this trailer in the daytime, and there's no hesitation as far as the structural soundness of the design and my installation. 470239

Trailer wiring kit was easy to install. Directions were easy to follow. My 2011 Rav 4 came with an accessory outlet in the drivers side rear panel right by the tail light assembly (see photo). The amperage max for the outlet was over what the lights on the trailer pulls so I spliced into the hot wire and drilled a ground connection nearby. My ATV hauler trailer lights work fine. My only complaint (and it is a small one) about the kit was that the wire lengths going to the other side of the car were BARELY adequate to reach even taking the shortest possible route The directions say to route the trailer plug wire out the door when used. I preferred to have the trailer plug mounted to the hitch rather than routed out the door. So I found a factory rubber drain plug grommet in the bottom of the rear storage area (where the spare tire goes if you don't have a rear door mounted tire like I do -- see photo). I took out the plug, cut a cross slit in it, cut the trailer wires and fed them through under the carpet, re-spliced the wires with wire connectors (and sealed them with dielectric grease to prevent oxidation) so that the splices occurred on the inside of the vehicle, sealed the rubber grommet with some black silicone and mounted the plug to the hitch with an angle bracket mount that accepts a standard 4 pin connector I got from the local U-haul dealer for $1.75(see photo). 13410

Good product but appears the module was changed/updated. The wires to the passenger side and the ground wire could not be attached per the etrailer video if you tried to place the module as suggested. This was due to the wires were to short. I improvised by choosing a location that would allow for the passenger side mounting and using the screw for on the "new" module mounting for the ground wire attachment too. This approach worked well. Kudos to Karen in customer service for quickly sending out the correct harness after the I inadvertently ordered the incorrect one the first time. Regards, Dan 371461

I had no problems installing this kit. The time it takes will depend on your experience. I spent about 2 1/2 hours total, but that included gathering everything I needed, fussing with tie wraps, finding a route for the power connection, and a final test. One thing I'd like to point out is that it's not hard to run the power wire inside the vehicle. The trim pieces at the bottom of the driver and passenger doors pop off easily. While you have the rear panel loose, fish a wire from the rear area to the bottom of the passenger's door. Run the wire along the door sills up under the dash, where there's another small trim piece that pops off easily. Look up behind the OBD connector and you will see a large rubber gasket which passes most of the wires through the firewall. There is a spare slot in this at about the 2 o'clock position. I pushed a fish tape through this and it popped out just above the strut mount in the engine bay. With a little fiddling, I was able to route the 10ga power wire along side the main bundle of wires, around the engine bay and to the battery. Now I don't ever have to worry about having a loose wire under the car. 12925

Pretty straightforward to install in a RAV4. Video was a huge help in showing how. Loosening/removal of RAV4 interior trim was easier than expected and goes right back together in a snap. One of existing tail light connectors was a bit sticky and getting it to release was a bit of a trick, especially since working by feel alone. As a novice pulling the wire thru the undercarriage up to the battery was the most uncomfortable part of the job but able to get it done working solo with RAV4 setting on garage floor. Used a long narrow flexible piece of plastic along with good ole duct tape to fish wire from below up to battery area. Wasn't able to get a good solid wiring connection on butt connectors with just standard pliers so had to run to the store for proper crimpers. After completing all connections, voltage tester showed everything worked properly. Ran out of daylight halfway thru job and by the next day my battery was drained... not sure why kit would do this when partially installed. Two days later after job complete battery is holding fine so it was just an issue during middle of the install. Only reason I gave 4 stars instead of five is that between ground wire and right side connector wire there needs to be 3 or 4 inches longer length... even so everything goes together fine. 258455

This is my third hitch+wiring harness combination from etrailer. The price was right, the shipping was prompt and customer service is great. The harness was complete and simple to install. The video instructions make it almost fool proof. The hard part is to route the 12v wire from the battery. I chose the under-the-car method as described in the video. Unless you are very small, plan to use a rack or as least lift the rear and then the front using ramps. Finding a good route for a wire that can carry that much current under the car is not an easy task and should be given considerable thought. I did it and I am satified, but it took a couple of hours and a lot of rolling around in the driveway to get a route that I liked. I wish there was also a video showing how to route it through the body interior. 71508

Have the trailer light kit for my son's Rav4...requires running a wire from the battery to the rear of the vehicle...it then has two easy connectors at each tail light...my son has done a lot of stereo wiring and sees no issue with the installation...he just needs some garage time and warm weather to get it done.....art c 325523

Product was easy to install, came with all necessary hardware and wires had enough slack to route nicely. I didn't follow the directions exactly, and ended up routing my cable without having to remove any trip panels. It took about 25 minutes to install this kit completely, including zip-ties to secure the power lead. I was so very happy to not have to remove any trim panels, just routing the cables under the plastic in the storage area, near the back bumper. The plastic was flexible and just allowed me to slide the cabling between it and the carpeting. I took a bit of time and just felt the wiring as it lead back into the taillight assemblies, and disconnected it from the taillight by pressing down on a locking tab in the top of the wiring assembly. It would have been easier if toyota made it easier to see up into the assembly, but following the wires with my fingers was easy enough. My only suggestion would be to the company to increase the length of the wire going to the right tail-light connectors, this would have made routing the wires without removing any trim panels even easier. If that were the case, I am sure I could have done this in about 15 minutes. 28714

Great product poor directions I purchased this product in Sept. of 07 but had not installed it until recently as I hadn't needed it. The only problem with the installation was the 2 similar connections on the passenger side which were not noted in the instructions. My Rav4 is an 07 and it still had the 2 connectors one of which wasn't visible. Fortunately I found a review on the internet which described the problem I was having. My only suggestion is that the installation instructions could be more complete. More pictures and description of the trim removal process, wiring etc. would be helpful. 3144

The kit was fairly straight-forward. The T-connectors fit beautifully onto the existing plugs. The hardest parts were getting the trim open, and fishing the wires. The positive lead had to go to the battery, so it had to be fished up front and through the firewall. The drivers side had a rubber grommet with a thick bundle of wire and the hood release cable passing through it. I noticed what appeared to be a hole on one side of the grommet. I used my inspection camera to see that I could easily punch through this hole with an awl. After the hole was punched, I lubricted the wire and it pushed through easily. After the connection was made, I put my tester on and everthing worked fine. 32795

Received my hitch, trailer tire, and wiring kit for our 2009 Rav4 this afternoon about 1:30. Because I had already checked out the installation process on he etrailer website. Everything went just as indicated so it was no problem. One pre-drilled and tapped hole in the frame was a bit rusty but I was also prepared fo that and I used a toothbrush with WD4 to clean the threads then chased that with one of the old bolts so not to mess with the threads of the new bolts. Believe me, etrailer has this stuff already figured out and there are few to no "unexpected" surprises. This was the 3rd etrailer hitch I've installed and all have proven to be very easy. 26705

This kit was a snap to install on my 2011 Toyota RAV4. It really was a "plug and play" installation! I watched the installation video a couple times before beginning the installation, and also made sure I had all of the needed tools at hand before beginning the installation. For removal of the threshold inside the cargo area I gently used a small thin gauge pry-bar normally used to remove floor moldings. Total installation time was 1.5 hours. Instead of running the hot wire from the ModuLite up to the battery, I decided to make use of the handy 12-volt outlet plug already present in the cargo area. The 12-volt outlet plug will indeed handle the amps/wattage of the ModuLite and the load to the trailer lights, with load to spare. (Also the existing circuit for the 12-volt outlet plug is already grounded and has a fuse.) I attached the hot wire from the ModuLite to a 12V plug that had 10g wiring on it. I used the butt-connector from the kit to attach my 12V plug to the hot wire on the ModuLite. (I salvaged my 12V plug and wire from a 400 watt inverter that I no longer use.) 12V plugs with wiring can be purchased for around $4.00 from Radio Shack, Fry's Electronics, or your local auto parts and electronics stores.) The 4-way flat trailer connector easily fit through the hole to drop down under the vehicle. I highly recommend this kit - installing the wiring myself saved me over $100 dollars in labor and this kit is much better than the U-haul kit. 174642

Ok! Here's the deal , my Lady friend and I are off to the famous White Mountains of N. H. . I was pressed for time to get this device the UPS truck came around 7:30 pm 8/12/2019, up this Am at 5:00, put the Toyota rav4 . on 4 ramps that I welded that are 28 inches tall the interior was removed last week,, ready to go. Once I had everything I needed for installation, it took me the longer end of 43 minutes, another 12 minutes to replace the interior, this 2012 rav4 only has 39,000 miles on it and I tow my 10 foot long, x 6.6 feet wide x 6 feet tall self made camper mini, more fun than my Prevost Liberty , Now! I will be putting this device to the test extensively, I did not use the MICROSCOPIC Tie Straps, I inserted the black wire in DOT air line as extra jacket, future snaking of wires, tied to perfection. I coupled the Flat connector to a mating flat connector running white, brown, green yellow wires into my 6 pole round bumper connector socket. With extra wire ( orange) for Led backup lights. SO! both male n female flat connectors are neatly tucked, bundled in the rear left panel. All works spectacular in the driveway. Longevity. WOULD I recommend this ( these devices) Reckon a big YES for now, in time perhaps I would be interested in re review, As for service , Sir Robert S. Performed as a professional putting my order together by phone, I paid for faster delivery by UPS. As for warranty? You would have to ask etrailer, The product Tekonsha T-one, I have for many years used this brand name . My next project is getting electric brake components for this little trailer Though I don't really need them . YET. BOTTOM LINE, I AM VERY HAPPY now I have proper lighting, simple simple install. So simple that I bet my "HOSS" that was watching could do it. Enough said, A Sincere Thank You Sir. Robert S. Jim Raymond New England 686800

Pretty great except for having to run a hot wire from the battery. I wish it was like the ones for tacomas where you don't need to do that.

The install went pretty easily, but not as quickly as I would've liked. Not so much because of the product, although a couple extra inches of length on the ground wire and passenger side taillight T-connector would have been useful, but the lack of space between the underside of our car and the ground made it a tight squeeze. I bought some working space by rolling both driver side wheels up on some auto ramps. It was much easier to route the power wire after that. Also, I recommend watching the video, and not just using the instructional paper. 667519

I purchased this product for my 2010 Toyota RAV4. It came in a very timely fashion, and everything that was supposed to be in it was there. I was able to find online video instructions of the installation that were VERY CLEAR, and made the process as easy as it could be. I was very intimidated by the installation process, but with the video, and help from a friend who recommended etrailer to me (after getting one for his Tacoma), the installation was not that bad. Every thing worked on the first try, and I hope to have years of use. I will use e trailer again for sure!!! 667507

This product worked out great. The connections can be a little challenging due to tight work areas but all went together well. The toughest part is getting the power line to the battery. 608714

  • Trailer Wiring Harness Recommendation for 2012 Toyota RAV4
  • We offer a few different brands that make trailer wiring harnesses for vehicles. Curt and Tekonsha are the two most popular brands. We have the best luck in terms of reliability with the Tekonsha kits so for your 2012 Toyota RAV4 I would recommend the Tekonsha kit part # 118412. I also attached an install video for this kit for you to check out as well.

  • Parts Needed to Install Brake Controller in 2009 Toyota RAV4
  • For your 2009 Toyota RAV4 there isn't a plug and play style of brake controller install harness so you'd have to hardwire one in with the # ETBC7 plus a 4-way kit part # 118412 if you do not have a 4-way already. Those two parts would be all you need to install the brake controller part # 39523 that you mentioned in your 2009 Toyota RAV4. I attached an install video for the ETBC7 installed in a Rav4 similar to your 2009 model.

  • Does Draw Tite Hitch for 2010 Toyota RAV4 Have Capacity to Tow 1,500 lb Boat Trailer
  • The trailer hitch part # 75235 has more than enough capacity to tow a 1,500 lb boat. It has max trailer towing capacity of 4,500 lbs which is more than needed for your trailer. You would need to check the owners manual of your 2010 Toyota Rav4 to be sure that you do not exceed the towing capacity of the vehicle as well. For trailer wiring you would want the part # 118412. Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with...

  • Best All-Around Hitch for a 2011 Toyota RAV4
  • For an all-around hitch for your 2011 Toyota Rav4 a 2 inch Class III hitch will be the way to go since they have higher towing capacities and more accessories built for them. The hitch I would recommend is the Draw-Tite part # 75235. This hitch has the highest capacities and lowest price so it would be your best option. It has capacities of 675 lbs tongue weight and 4500 lbs towing. I attached an install video for you to check out as well. Since you wanted to do some towing you might...

  • Trailer Hitch and Wiring Harness for a 2011 Toyota RAV4
  • To add a trailer hitch and wiring harness to your 2011 Toyota RAV4 you can use Draw-Tite Class III trailer hitch # 75235 for the hitch. I also recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag. If the ball mount kit does not have the right rise or drop to tow the trailer level, use the link...

  • Tow Ready Trailer Wiring Harness #118412 in a 2008 Toyota Rav 4 Blows Stop Light Fuse
  • I spoke with my contact at Tow Ready about the trouble you have been having with the Trailer Wiring Harness, # 118412. He stated that on some Toyota Rav 4 models, the chassis ground is not a sufficient ground for the converter box. This will cause some power to leak back through the system and can cause the issues you are describing. To fix the problem you can move the ground. There should be a near by 12 volt power outlet that uses a different and stronger ground that you can use instead....

  • Wiring Harness Not Powerful Enough to be Used with a Trailer that Needs More Amps
  • The maximum amp rating for the T-One Wiring Harness are as follows: Maximum stop/turn light: 1 per side (2.1 amps), Max. tail lights: (4.2 amps). This rating is even with the hot lead pulling power directly from the battery. For your application, you will need to use a Heavy Duty Modulite, part # 119190KIT, which is rated for 15.9 amps. This kit does not plug directly into the vehicle, so it must be hardwired. The Kit includes 20 feet of 12 gauge wire for attachment to the battery.

  • Trailer Hitch and Parts Needed to Tow Cargo Trailer with 2010 Toyota RAV4
  • First let's start with a hitch for your 2010 Toyota Rav4. For that the Draw Tite hitch part # 75235 would be a great option. It has plenty of towing capacity at 4,500 lbs trailer weight and has the best price. I attached an install video for this for you to check out as well.

  • Trailer Hitch Recommendation for 2012 Toyota RAV4, Choosing Class II or Class III
  • For your 2012 Toyota RAV4, I recommend going with a Class III trailer hitch because it will offer a 2 inch hitch receiver. A 2 inch receiver will allow you to carry a wider variety of hitch-mount accessories than the 1-1/4 inch receiver on a Class II trailer hitch. If you already have several hitch-mount accessories that fit a 1-1/4 inch receiver, or simply like the look of the smaller receiver, the Class II hitch is a good option. Since these Class II hitches are still within the towing...

  • Difference In Factory Hitch And The Draw-Tite Class III 2 Inch Hitch # 75432 On A 2006 Toyota RAV4
  • The Draw-Tite Class III 2 Inch Hitch, part # 75235 will use existing weldnuts on the vehicles frame rail. It only uses 5 bolts and washers to install the hitch on a 2006 Toyota RAV4. The Class III hitch is rated for 3,500 lbs. towing weight capacity and 350 lbs. tongue weight capacity, but you will need to check your owners manual or with the Toyota dealer for the towing capacity of your 2006 Toyota RAV4. You will always use the lowest rating between the vehicle or the hitch, as the...

  • Curt or Tow Ready Trailer Wiring Harness Recommendation for 2009 Toyota RAV4
  • There are two wiring harnesses available for your 2009 Toyota RAV4 that you mentioned. The Tow Ready part # 118412 and the Curt # C56165. Both are custom fit harnesses that will work well for you that are made by different manufacturers. Since we have better luck with the Tow Ready brand I would recommend the # 118412 which I attached an install video for.

  • Troubleshooting a T-One Vehicle Wiring Harness # 118412 Installed on a 2006 Toyota RAV4
  • 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 # PTW2993 and test the wires going into the box and then out the other side. I would start on the left blinker signal wire on the input side of the box. You will want to test for intermittent voltage on this wire, and then again on the output side of the box....

  • Does a Trailer Wiring Harness on a 2011 Toyota RAV4 Require a Separate Power Wire to the Battery
  • The Tow Ready wiring harness, part # 118412, and the Curt wiring harness, part # C56165, that are available for a 2011 Toyota RAV4 will both require a separate power wire be ran to the vehicle battery. The separate power wire is used on many of the newer vehicles, because is getting smaller and more sensitive with generation. Because of the newer wiring, there is more of a chance of running too much current through the smaller wires and causing a circuit to be over drawn, potentially...

  • Running a Power Wire on a 2009 Toyota RAV4
  • You should not run the power wire from the T-One Vehicle Wiring Harness, item # 118412, to the 12V at the back of your vehicle instead of running the hot lead to the battery on your 2009 Toyota Rav 4. You need to isolate the trailer wiring from the vehicles sensitive circuitry. Tapping into the vehicle 12 volt supply at the back of your vehicle will put your vehicles wiring at risk. You also need to be sure and install the included in-line fuse holder and fuse to protect the converter.

Only the two screws included with the carrier will be needed to attach the top holes of the plate to the bracket on the...

  • Curt Trailer Wiring Harness Shows Constant Power
  • What you are describing seems to be common in some Curt trailer wiring harnesses that use a powered converter. If you were to pull the fuse out of the fuse holder it should not show power any more (with the vehicle on or off). I would recommend going with the TowReady equivalent part # 118412. This harness is also compatible with your vehicle, and will install in the same manner. We have an installation video showing this harness being installed on a 2009 RAV4, click on the provided link.

  • Is Brake Controller Install Procedure for 2010 Toyota Rav 4 Same as 2011 Model

The procedure shown in the video will be the same as what you'll use on your 2010. The parts you mentioned are exactly what you'll need, but you'll also need a # 118412 trailer wiring harness (unless your RAV 4 is already equipped with a 4-pole trailer connector). I'd also consider using the long bracket, # C57202 instead of the short # 18140 to provide...

  • How to Activate the 12 Volt Power Circuit of a 7-Way at the Rear of a Vehicle
  • If you have a 7-way at the rear of your 2008 Toyota RAV4 this would provide you with a way to supply 12 volt power to your trailer through the 12 volt power circuit. The pin in the 1:00 position should have 12 volts at all times as long as the 7-way is wired up properly. If this pin does not have voltage you can run a length of 10 gauge wire like part # 10-1-1 (sold by the foot), from the positive post of your battery to that pin on your 7-way through a 40 amp breaker like part # 9510.

Some wiring harnesses can pass a tiny amount of power at all times - even when the light functions are NOT actually activated on the vehicle - that can cause sensitive LEDs to light up. You are right that normally only the 12V circuit's LED should be lit. You can find out for sure by disconnecting the adapter and...
