Tekonsha ModuLite Wiring Harness with Powered Converter by Draw-Tite, Hidden Hitch and Reese

You’re gonna love this! I put the hitch on my Corvette to haul a small luggage trailer on long trips. The hitch works great!

Everything fit perfectly and we (my wife and I) got it all assembled within a couple hours! (We haven't done the wiring yet. That will wait for another day.) Taping the washers to the frame, as was suggested in one review, was most helpful. It was only necessary when attaching the last end, because the bolts had to be pushed all the way back for that end to be put in place.

The shipping was quick and free however the packing of the shipping box was very poorly executed. An electronic device, a circuit protected trailer light power module and accessories were shipped in a 10x7x5.5" box with no packing materials to keep the contents from being bounced around in the box which base on the visible crushing of the box was bounced around quite a bid during shipping. Any item shipped needs to be packaged to prevent it from free movement in the box. bouncing around in a box is the worst thing for an electronic device. I hope the module has not been damaged. I ordered this to replace a module that experiences intermittent failure in my vehicle apparently from something damaged in the module.

Thank you for sharing. I will send this information to our shipping department for review. Please contact us immediately if the harness is not working for you.

2014 WRX wagon at taillight: WHT/RED = Turn signal
BLK/WHTstripe = Running light
BRN = Brake light
I mounted the modulator behind the left turn signal. I routed the power wire through the trunk via rubber access plug. I then fished the power wire under rear seat and stuffed it under plastic trim molding along the doors. I went behind left kick panel and then came out and ran it into the fender well, between the door and the fender, and up a structure tube into the engine compartment. The wire is safe from damage and will not be crushed by shutting the door because of the rubber door seal. I ran my XM ant. wire like this also and there are no negative consequences.

Etrailer always comes through with products that are easy to use and at a fair price. The auto trailer wiring kit was easy to install, and works good. All the products I've ordered from etrailer have been great.Great company to do business with.

by: Robert08/12/2022

I haven't installed the hitch or the wiring harness as of yet as I only received everything Thursday in great shape I should add. The wiring looks a little complicated but like I said only yesterday I received it yesterday, but it pretty much looks straight forward.

The installation isnt terribly difficult, its just a matter of using the included circuit tester to determine which of your taillight harness wires provides which function, then making the appropriate connections. Ill link to a typical installation video which should provide you with some direction. The wire color coding on your vehicle would likely be different from what the video shows, but the procedure would be similar.

Unit easy to install if you watch the video first and take notes on which light wire in the car goes with the appropriate wire on the module.

Quick shipping with constantly updated tracking information.

The videos are fantastic! Even if we do not have your exact year, make, or model, they will still be helpful. Not all wiring is the same, but on this module the green wire is the passenger turn signal. The yellow wire is driver turn signal. The brown wire is the tail light. The red wire is the stop signal, if you have separate lights from the turn signals. If it is not separate, just ground the red wire. The white wire is a ground and the black wire is ran to the battery positive.

It feels heavy duty and is working exactly as it should. Easy wiring in my 2005 Passat TDI. The most difficult part was bring the 12ga wire from the battery to the rear of the vehicle. The effort was worth it; I have a professional looking install that works perfectly.

The product works perfectly. A year later it still looks and works like a factory installed item.

I recommend the Tow-Ready 119147KIT instead of the Curt Model for a 2013 Prius. I had to return the Curt Kit because the running lights/tail light stayed on all the time even with the vehicle off. Sometimes there wasn’t a tail/running light on if you reset the converter by removing and re-installing the fuse. This Tow-Ready model works like it should. You'll need 12 gauge wire to run from the battery, (right side hatch area,) to this unit which will need to be mounted on the driver’s side, rear hatch. At the very top of the left rear tail light are covered wires going into a plug. The Blue is the Stop light and the Brown is the tail/running light. (Be careful since these wires are thin solid copper wires.) Left turn signal is the green/yellow stripe wire and on the right side rear lamp the right turn signal is also the green/yellow stripe wire. You will need to remove the left rear panel to get to the blue and brown wires. Remove the bottom tray cover, the bottom tray as well as the left rear plastic tray and the plastic bottom hatch trim over the latch assembly. Remove the Phillips screw on the left rear panel as well as the chrome tie down clamp. This sounds harder than it really is. Good luck!

Thanks for the installation details. I also have a 2013 Prius and everything went a lot smoother with your information. I didnt even need a test light.

I agree - very helpful information on installing on a 2013 Toyota Prius. This told me which wire was which light and even gave helpful tips on removing the panels that I was sure I couldnt do, until I read what you wrote. Thank you so much- saved me lots of irritation.

Comprehensive kit - came with everything needed for easy installation! Would highly recommend for anyone needing to power vehicle trailer lights. The online PDF was very helpful as well to see the wiring diagram and be able to view >100% for those with difficulty reading the paper instructions :)

by: Bill12/10/2021

This kit lacks any type of instruction in the package but appears complete. At the price I expect clear instruction without needing to look for them online. The leads on the module are about 5 or 6 ft too short to be of use on the 2022 Sorento PHEV SX I have, ground and power are only identified on your installation video. As well, the splices provided are for wires larger that in that vehicle leading to failed connections on each wire!For the price I paid I certainly expected that I would NOT have to scour several local shops for the parts to finish the job nor to have to refer and search necessary information!.

I will have our customer service team reach out to you. This harness is a hardwire harness that works with a variety of vehicles. I recommend taking a look at the installation video that we have on a 2019 Hyundai Tuscon. I also recommend checking to see what gauge of wire your vehicle uses. The provided blue taps are for 16-18 gauge wire only.

Ordered this, together with a hitch receiver. etrailer waited a month to update the delivery date for the hitch receiver to 3 months ahead, so I canceled the hitch receiver and requested they send me this Upgraded Modulite vehicle wiring harness kit, which came incomplete. I called and got the rest of the items sent, which took another week. Hopefully installation goes as indicated int he instructions.

by: Beverly 09/26/2021

I purchased a trailer and connector for my Lexus NX300 Hybrid and it works well!! The Lexus dealer told me I could not add a trailer or I would lose the ability to use my foot to automatically open up the trunk (sensor). However your team told me that I could have the trailer and not lose access. Your team was correct and the trailer has come in handy. We have not carried anything on the hitch yet, but know we can if needed. Also, the trailer is very nice looking... you can barely notice it.

Great kit. Installed in 2021 Kia Sorento. Would advise soldering the wires into harness instead of using the crimp connectors. Fits well in same compartment as tire kit under back deck. Would be nice if the manufacturer instructions were included. Other than that, very happy with it.

Just completed the installation of the 119147KIT on a 2014 Lexus RX350 and it works great. Everything needed was included in the kit and the installation process was fairly easy. As always when I purchase items from e-trailer things fit and the right amount of supplies are included as well as installation instructions. i have always had excellent service from e-trailer and have great confidence in doing business with e-trailer. I know that i will get a great product with support, if needed, and always a follow up e- mail to see if everything was OK.
Great place to shop.

This was installed on a Lexus that does not have the factory tow package. It work just fine and has had no negative effect on the vehicle. Note, I tow a very small utility trailer on short trips and wanted the lights on the trailer to work properly.

My RX350 Lexus did not have a towing package, and I used this kit for getting all the trailer lights to work. It took me a little more time to make the electrical connections as I needed to probe individual wires to ensure I was connected to the correct wires. Once completed, everything worked fine and still does. Glad I did it.

Still works.......

  • Comparing Tekonsha ModuLite 119147 & 119190 Kits For Use On a 2022 Chevrolet Bolt EV
  • The Tekonsha ModuLite # 119190KIT has a heavy duty circuit board. This allows for it to provide up to 4.2 amps of power to the tail lights where the ModuLite # 119147KIT will only provide up to 2.1 amps of power to the tail lights. For your 2022 Chevrolet Bolt EV there really is no need for the heavy duty module. The # 119147KIT will be more than adequate as you will not be hauling larger trailers which use multiple tail lights for visibility.

  • Difference Between the 119147 and 119147KIT Trailer Wiring Harness for a 2006 Volvo XC70
  • The # 119147 and # 119147KIT are the same part with the only difference being that the # 119147KIT provides the installation kit that includes the wire needed to connect the converter to the vehicle's positive battery terminal, the fuse holder, the fuse, the installation hardware and the circuit tester to help determine which taillight circuit carries which taillight function. The # 119147 only includes the powered taillight converter and none of the equipment needed to install it.

  • Difference Between Tekonsha Trailer Wiring Harness # 119147 and # 119147KIT
  • You're correct. Using the 'KIT' suffix after the part number provides the power wire feed to the vehicle battery and the fuse holder, which you won't need (assuming that your existing power feed and fuse holder are in good shape). The # 119147 is exactly what you'd need. However, before installing the replacement, you'll want to closely examine the wiring on the trailer to determine if there was a short in the trailer wiring that caused the converter's demise.

Would not work for my vehicle. I had to repin the connector to get it to work properly. NON led lights.
This was not in the description anywhere that this part would not work with non led lights.

This converter worked great on my 2018 VW Alltrack. The way I've got it installed, all the wiring is inside the trunk and never exposed to the weather so I expect it'll last a while. When I hook up a trailer I just pull the leads out, and close the trunk lid on the wire. As long as you don't close it on the actual 4-pin connector there's plenty of clearance between the trunklid and the floor while closed so the wires don't get pinched.

2015 Audi Q7

2017 Audi q7 is a "2 wire" setup. I finally figured that out, grounded the red wire and everything works beautifully. I also pulled my power from the fuse box in the left rear luggage area. The red bus has 25 amp fuses. I installed a buddy fuse adapter with the 15 amp fuse that came with this kit. That saved me a lot of time taking apart panels to get to the battery.

You mentioned that you wired the power wire to the fuse box in the left rear luggage area. I wanted to let you know that it is not recommended using the 12-volt power outlet in the trunk area. The purpose of the powered harness is to eliminate the power draw on the vehicle rear electrical circuitry. Taking power directly from the vehicle battery is the only way to eliminate the draw on the vehicle electrical system.

Installation stretched my limits, but we will blame that on the car and on my narrow limits. It is a tight and clean install. Has worked flawlessly this past year. I used it just yesterday to haul junk and brush about 100 miles for disposal. I would definitely buy this hitch again.

Wiring harnesses are the bane of my existence. This one was more work to install than the non-powered alternatives. But it has been trouble free. Just sold the car a week ago. I am sure the new owner will have no complaints.

Got this to install in my 2016 Volkswagen Golf. I had a mechanic do this one, which gave me the option of the 4-way connector, then proceeded to install a 4-way-to-7-way adapter in addition to running a line from the car battery, to tow a 13' Scamp fiberglass trailer. 2 years later, it's still working just fine, no problems or issues.

2019 Volkswagen Golf SportWagen

I tried to follow the directions and code the wires to the car's function. The brake/directional were on the same wire and easy. However, the taillight was testing on two of the remaining wires. I called for clarification and was given the incorrect wire by two different techs. I had to cut that wire and attach to the remaining wire and everything appears to be working properly now.

One year later and about 3000 miles on the wiring, everything is working as it should. It is scary to close the tailgate on the wiring, but appears to be okay. Just dont get it near the latch!

by: Tom06/11/2022

Worked for the first trip and then lost brake and tail lights. Frustrating for an expensive converter.

2013 Audi Q5

Pretty straight forward install on a 2013 Audi Q5 S-Line.

There is an ground lug on the rear inside panel right next to a convenient spot to mount the unit.

I removed the silver panel along the tailgate sill to route the power wire and the trailer plug tail before I started. It clips off easily, and you can reach between the side panel and the battery compartment with your fingers. There's a small electrical connector on the panel, so be careful to disconnect it before yanking on it. Make sure you replace this panel as soon as you have routed the wires, as that electrical connector is to two micro switches that detect if the door is closed... there is no power to the rear lights while the tailgate is up, so this panel needs to be in place before you start wiring.

Correct wires were easy to locate. The 2013 Q5 is a little different to the wiring types listed in the instructions, as while the brake runs off the turn signals, there is a separate tail light wire. If you are probing for the wires, close the tailgate, and climb in through the rear passenger door.

Here are the correct splices off the tan connector...
Tail Light (Brown) - splice to Black with Green trace
Left Signal (Yellow) - splice to Gray with Black Trace
Right Signal (Green) - splice to Gray with Blue trace
Red and White both Grounded together.

The only issue I had was that the blue splice connectors supplied are too big for the fine wires on the Audi, so when I tested the install, I had nothing working. I replaced the blue connectors with the smaller red ones, and all worked perfectly then.

Start to finish, about 90 minutes.

by: Charles03/18/2021

  • What is the Difference Between Curt Wiring Harnesses # C56175 and # C59236?
  • Both the Curt # C56175 and # C59236 will add a 4-way trailer connector to your 2006 Volkswagen Golf. The main difference between these products is that the # C59236 is a powered tail light converter, which means it gets wired to your vehicle's battery instead of only receiving power from your vehicle's tail light circuit. Basically, what this does is limit the power drawn from the tail light wiring to isolate your vehicle wiring from your trailer wiring. In case there is an overdraw situation,...
