Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the passenger's-side interior trim panel in your rear cargo area. Once you've plugged in the tow harness connector, locate the battery harness plug behind your headlight assembly and plug in the fuse holder wiring harness. Run the harness to your battery and connect it to the positive terminal. Then insert the included 15-amp fuse into the in-line fuse holder.
Once installation is complete, the 4-way flat connector will be stowed within the jack storage compartment of your rear 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.

Easy installation of harness and module at rear of vehicle as per instructions . Locating power plug at front of vehicle not so much . 2013 Outlander plug is black not grey and is located under the left headlight closer to the grill requiring removal of battery to access plug with right hand and putting left hand through a small opening above plug to remove plug cap and install power connector . See pics.

After receiving my kit and reading directions.by the way the reading directions is the most important because you find how easy it is. Perfect fit plugs right in to my prewire. I was so excited and use it everyday. Never a problem. Thank you etrailer

The trailer hitch outlasted the car, just kidding solid construction and excellent wields
by: mgierlach06/07/2016
I bought my trailer hitch a year ago. I'm very satisfied. When I bought the hitch I never bought one and I ordered the wrong wiring. They replaced it for no charge. Very helpful and kind. Something that is forgotten these days. It was easy to install. All you need is a 1/2" circular wire brush. You can find them in the plumbing section. And socket wrench.

The module was an easy plug-in installation in the rear right interior wheel well. The power tap lead was hard to find in the engine compartment, but the plug-in feature instead of splicing wires made it worthwhile. The positive battery connector had an open connector for easy bolt-on installation of the power lead. Great product.

Product was exactly as described and very easy to install. Everything just plugs into the existing wiring harness in the car. Only took about 15 minutes to install.
I also like the prompt emails notifying me when the order was placed and shipped. Would definitely purchase other items in the future.

Installed the hitch and electical harness all in about 2 hrs as Im a shade tree mechanic. So simple, loved the videos that come with your service, worth a million words. Of course, the time included, ill clean this while I have it open and Ill fix this and that while Im here. Easy peasy guys, plug in and e-trailer lays it all out for ya.

This harness was very painless to install. Since it was vehicle specific, it plugged right into my vehicle's existing harness. the video on the etrailer website was also very helpful. After watching the video, I was able to find the hidden connector under the hood that I needed to use for installation.

Wish I had consulted etrailer 2 years ago. Found a legacy part with etrailer that solved trailer lighting problems I've been having ever since we bought our rv. It was the car and not the popup trailer all along. Etrailer videos are a great resource for dummies like me, and etrailer always seems to have the part needed. Thanks Etrailer!

Took about 20 minutes to install. Despite being warned the hardest part is finding the receptor up by the battery. Mine was taped to the harness directly underneath the headlight assembly.
by: Chris 03/20/2019
This made installing my hitch system a dream! I originally was concerned about tapping in to all the wires of my car like I have in the past (I usually end up with some crazy issue down the road) when I stumbled on their YouTube video showing how to wire this with a link to this site. I immediately ordered the part and it arrived so much faster than I anticipated. Installing was a breeze and the video they provide was absolutely perfect.
by: Matthew 03/12/2021
Very easy to install, instructions were clear, youtube video was very helpful.
Would buy from them again; worth the extra money for a new, complete harness

- Where is the Grey Connector Under the Hood of a 2012 Mitsubishi Outlander to Install Trailer WiringYou are going to have remove the battery hold down bracket and carefully move the battery just enough so that you have access to the rear of your headlight assembly. There should be a grey 4-pin harness taped to a harness behind the vehicle headlamp. It will probably be out of plain sight and will require a little bit of exploration of the area to find it but you will eventually find it.

It will be on the driver side. You will need to move it rearward as much as possible, or completely remove it from its position, to gain access to the area behind the headlight. Look for the wiring harnesses behind the headlight. Taped to one of them should be a wire with a gray connector on the end that is not connected to anything. It is possible that the harness is further back or has fallen off and...

view full answer... - Making the Connection Under the Hood of a 2011 Mitsubishi Outlander for Trailer WiringThe connector under the hood of your 2011 Mitsubishi Outlander may not be gray. All indications suggest that there should be one connector there that will fit the harness in # 118518 so it does sound like you have the correct harness and plug. If the plug in question is located in the same location as in the video I have linked, then it is correct.
view full answer... - Will a Bad Ground Cause Tow Ready Custom Fit Wiring for a 2007 Mitsubishi Outlander to Stop WorkingYes. A bad ground connection can cause all sorts of wiring issues including not allowing the system to work at all. If there is a bad ground, the circuit will not be completed or it would only work intermittently. The ground should be connected to a clean bare metal surface that is free of corrosion. With the T-One Connector with Upgraded Circuit Protected Modulite, # 118518, if the fuse is blown, that would also not allow the system to work. However, if the fuse has blown, that would...

It draws power for the trailer lights from the vehicle battery and not from the tail lights. This harness connects to some pre-wired components on the vehicle which does not affect the tail lights on the vehicle so it will not produce excessive draw on vehicle LED tail lights and it will work fine if the trailer has LED, or incandescent tail lights. I have included a link to the...

- How to Find the Power Wire for the 2012 Mitsubishi Outlander for Trailer Wiring InstallationCheck out the video I attached to see exactly where the power wire on your 2012 Mitsubishi Outlander is for the T-One Connector with Upgraded Circuit Protected Modulite # 118518 is. Some harnesses on vehicles can be very difficult to find. My best advice that I can give is to make sure you have plenty of light so you can see what is going on and to just be patient. It is there and you will find it eventually.

- Removing Cap from Wiring Harness Behind Battery of 2012 Outlander to Install # 118518 Trailer WiringTo remove the protective cap on the wiring connector, there is a release button on the side of the connector. Push and hold the button while pulling off the cap. You might need to use a set of locking pliers to get enough grip on the cap, but make sure not to damage the connector itself. You can see the button I am speaking of in the photo I have edited for you.

- Location of Wiring Harness Power Wire in Engine Compartment of 2012 Mitsubishi OutlanderThe power wire for your Tow Ready T-One Vehicle 4-Pole Wiring Harness # 118518 should be located behind the driver-side headlamp as you note and as illustrated in the linked video. If you refer to the 1:23 mark in the linked video you'll see where our installers found the vehicle harness after removing the battery from a 2007 Outlander. It is possible that the exact location of this plug will vary. Try moving the other wiring out of the way. You may also have better luck checking from...
view full answer... - Troubleshooting Blinkers Hyper-Flashing on a 2007 Mitsubishi Outlander after Trailer Wiring InstallI spoke to my contact at Tow Ready and he said that what he would recommend you do is run a jumper cable from the ground on the harness back up to the negative battery post of the battery on the vehicle to make sure you have a sufficient ground. If that does not fix the problem then the harness would need to be warrantied.

Both work on your Outlander. The connector in your photo certainly appears to be the correct mating connector for the harnesses.

- Trailer Hitch Recommendation for 2008 Mitsubishi Outlander for Towing Quicksilver TrailerThe Curt hitch part # 13581 would be a great option for your 2008 Mitsubishi Outlander as it is a confirmed fit and has great towing capacities at 4,000 lbs total trailer weight and 400 lbs tongue weight. I did some research on your vehicle though and it has a capacity range of 1,500 to 3,500 lbs depending on how it is equipped so you will need to check the owner's manual of your vehicle to verify what the capacity is and go by it as the overall capacity. For trailer wiring you then would...

The Curt Hitch, part # 13581, has the safety chain hooks at the bottom of the receiver and the Draw-Tite has the safety chain attachments at the top of the receiver opening.

- Trailer Hitch and Wiring Option for 2007 Mitsubishi Outlander for Towing Small TrailerThat's going to depend on a few things. How much does the trailer weigh? What does the owners manual of your 2007 Outlander state as the towing capacity? From the research I did on your vehicle it has a towing capacity of between 2,000 lbs and 3,500 lbs depending on how it is equipped. If your trailer will weigh less than 2k than it's going to easily be towable. The Curt hitch part # 13581 is a fit for your vehicle and would work well. It would have more capacity than you'd need so you...

A big thanks to wingnut for the tip on the bolt.I went to the slide-out drawers at my local hardware store and found they had a couple of drawers with metric screws.I used the M6 x 10mm size, to be more precise to the designation on the box.It might be worth checking the other postings about finding the gray connector behind the headlights.I have a 2013 Outlander GT not sport, and it was *very* tricky to find. It was black, not gray, and below the headlight, taped to a wiring harness. Use a flashlight to help see it.I got away with leaving the battery in place, i didnt want to lose my radio
