Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area on the driver's side. You will have to remove the cargo strap and some interior paneling to access this harness.
Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
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.
Tail Light Converter
A tail light converter is built into this T-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 the trailer. This converter combines 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.

Simple Installation, No modifications needed. Note: On the Jeep Liberty the floor plug for the wire run is above the tailpipe. Secure the wiring far away from the tailpipe.

Purchased for 2006 Jeep Liberty. Installation was a snap. I pull my utility trailer alot and this unit has been trouble free. In the old days I would cut into my vehicle wire harness to add a trailer connection. Not anymore! This Hopkins adaptor is deffinetly the way to go.

Many Thanks

Installation was perfect and a breeze. It’s been over a year of use and no issues at all. I will definitely contact trailer for any future wiring needs
by: Jeremie03/27/2020
Recieved the hitch and writing promptly. Wiring was easy to install and works like a charm. Wish it came with some mounts for clamping it up as you pretty much have to depend on zip ties and all the vehicles structure. Took about 20-30 min to install and maybe an hour for non-mechanics.
Hitch took about half hour to install and works great. Very rugged. Was able to handle a small wreck while towing with no evidence of cracking.

Pretty straight forward installation on my 07 Liberty. The hardest part was getting to the right plug in, as on my vehicle there was little slack wire, but it wasn't brain surgery.
Follow the directions, which were pretty good, and you'll be wired up in half an hour, and 25 minutes of that time is removing the plastic trim panels and re-installing them. Next vehicle I need to set up for trailering, I'll be checking etrailer first to see if a ready to go system is available.
2 months of frustration in trying to wire it stopped right here!
by: Mike S04/13/2017
This product works. We replaced the exact same brand/harness that we had previously installed years ago. It had quit working. We assume it was the wires at the plug that had broken as they are not protected. I would recommend buying the optional bracket to permanently install this on the hitch or at minimum use some electric tape and maybe plastic to protect the wires better.
But still a good harness. I used some dielectric grease on all connection points. It comes with a small packet. U may want to buy some extra.

The service by E-Trailer staff is unsurpassed. I had several questions prior to purchase and they were all answered quickly and succinctly. Also my Jeep Liberty didn't "fit the description" of how to access the connection behind the passenger side rear panel; but they didn't pass it off, still tried to assist even though my vehicle was different (in case others run into this: my Liberty had no cargo bracket to remove; just take off the weatherstripping, and pry the panel off towards the center of cargo area). Job was very easy and had my wiring done in about 40 minutes. Longest part of job was being sure I kept wire away from exhaust, but it was no problem. I will definitely recommend and use E-Trailer again, Thanks
by: Gino 04/14/2021
Very easy to set up and start towing. Much happier that I decided to buy the kit rather than buying the trailer plug and trying to wire it into the vehicle wiring myself.

The instructiosn did not match my car, there was no way to get to the plug from the inside, so I had to take off the whole inside panel off. The yellow slide switch on the plug did not release the plug lock, I figured out with a flat head screw driver stuck in-between releases the lock. Them to top it off, after everything was assembled, the trailer lights did not work!!!! I hope your customer service is up for a challenge.

I installed Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
Item # 42475 this morning and the harness went in without any problems and it functional checked as well. Sorry about not having pics, as I was in a hurry to get it done and forgot . I did find it easiest to pull the plastic panel behind the back seat on the passenger side out in order to access the plug for the tail lighting.

Extremely easy to install, works real good. Drove from one side of the states to the other, with no problems

The wiring harness was easy to install, and it worked perfectly fine. I am happy to be able to hitch the trailer to the Jeep Liberty.

Ordered the required wiring harness with converter for use with trailer hook up. It arrived when it was supposed to and installation was a snap. instruction were included which made the job even simpler. When I took the trailer for the required state inspection it passed with flying colors. So once again great job from 1AAuto on the timely shipping and the correct part. Thanks folks

After ordering this my shipping was upgraded and my part shipped out the next day. My part was securely packed within the shipping box with all parts included. Installation time on this was around 10 minutes, and made easier by the videos.
I would recommend these guys.

The part worked perfect, the installation was done in 15 minutes. I like the fact that I can keep the plug connector inside the Jeep, in Michigan the road salt tears up trailer connections.

This is an excellent product that is every bit as good as the Jeep OEM part. Installation was a breeze and the directions were spot-on. I am glad I did some research before purchasing anything. This product is everything I expected and then some. Yes, it is THAT good.

Wow, not used to something being this easy! Pulling the plastic off the wheel well is the only pain and make sure you have a drill for the ground wire, left mine somewhere else. So I just bolted it to a hole in the wheel well instead with a spare bolt and lock nut.

fit like a glove, no problems with the installation or instructions to install, would buy from etrailer again if a similar need ever arises.
by: Erine04/06/2020
Easy installation, almost... The ONLY criticism is I wish there was a video on how to take the pannel apart to get to the plug in... I found nothing on the internet... I work best with video presentations, along with alot of other people... Make a video and YOU WILL BE FAMOUS...

The kit fit our Jeep perfectly. The instructions were clear as to how to install the part. One improvement that could be made is to mention that the connector has a tab that must be pressed to separate them. It took a while to figure that out.
by: Mark D11/12/2019
i have had to work on it twice to keep trailer lights working
by: Allen S.08/31/2011
Simple to install and worked with no problems. I towed a trailer 300 miles the day after the installation.
Best part was that the item was quickly delivered to allow for me to help out a family member in moving.

See what our Experts say about this Hopkins Custom Fit Vehicle Wiring
- Connection Point For a Hopkins Trailer Wiring Harness on a 2006 Jeep Liberty without Tow PackageFor a 2006 Jeep Liberty, the OEM plug is located behind the paneling in the back of the vehicle on the passenger side. There is a grommet located in the floor to allow for the 4-flat connector to be run down by the trailer hitch. I have included a link to the installation instructions for you.
view full answer... - Fit of Hopkins # 42475 Trailer Wiring Harness on 2003 Jeep Liberty w/o Tow PackageThe Hopkins # 42475 Trailer Wiring Harness is compatible with all models of the 2003 Jeep Liberty, regardless of whether it has the tow package or not. I've confirmed this with my contact in the Tech services department at Hopkins.
view full answer... - Wiring Harness Recommendation For 2006 Jeep Liberty Without Factory Tow HarnessThe Hopkins Plug in Adapter, part # 42475, is not designed to work with your 2006 Jeep Liberty, but we do have a solution that will work for you. For your Liberty, you will need to check to see if your vehicle has the necessary connector and if it is active. You would need to locate the connector at the rear of the vehicle that should be near the drivers side frame rail by the spare tire. You can use a circuit tester like part # 3808 to test the pins of the connector for the various taillight...

You will need part # ETBC7, which is our Brake Controller Install Kit. The Kit comes with everything needed to install your brake controller, including a 7-way trailer connector adapter that will plug directly into your existing 4-pole trailer connector. If you have not yet decided on a brake controller, check out the Tekonsha Prodigy P2, part # 90885. The P2 is our best selling controller, primarily because it is so...
view full answer... - Hopkins 5-Way Vehicle and Trailer Connectors # HM47890 Recommendation For Charging Trailer BatteryYou will need to run a wire from the positive post of the battery on your 2005 Jeep Liberty to the black wire that runs to your trailer battery. This will charge the battery of your trailer while the wire is connected. I would recommend you cut off the the 4-ways that are on your vehicle and 1988 Jayco popup and then install 7-ways instead so you could have a designated trailer battery charging circuit that would charge your trailer battery when it was connected. For this, I would recommend...
view full answer... - Recommended Trailer Hitch for a 2004 Jeep LibertyAll of the hitches we currently offer for a Jeep Liberty will fit years 2002-2007 and no other vehicles. The trailer hitch I recommend for your 2004 Jeep Liberty is the Draw-Tite part # 75128. It's a Class-III with a 2-inch receiver. The maximum gross trailer weight is 5,000 pounds and tongue weight capacity is 500 pounds. If you plan on doing any towing, the wiring harness kit you need is the Tow Ready # 118524. Or if you already have a factory tow package then go with Hopkins custom...
view full answer... - Easy to Install Wiring Harness on 2004 Jeep LibertySince your 2004 Jeep Liberty does not seem to have the factory 7-way, the easiest to install 4-way that fits your Jeep is the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 42475. You'll only need to plug this into your Jeep's harness, and getting to that is likely going to be the most difficult part as you'll have to remove some interior paneling to find it. Then for lights, I recommend going with LED marker lights. Ten marker lights is quite a bit...
view full answer... - Missing Red Power Wire for Hopkins Wiring Harness # 42475 on 2006 Jeep LibertyThe Hopkins Wiring Harness # 42475, does not require a wire be ran to the battery for a power source, this is why there is not a Red wire included in the packaging. In the original design of the wiring harness Hopkins recommended the separate power wire be ran to the battery. Later, Hopkins found that the Jeeps wiring harness supplies enough power for trailer lights, so the wiring harness was redesigned, and the separate power lead is not required or included. Hopkins has just not updated...
view full answer... - Trailer Wiring Harness Recommendation for a 2005 Jeep LibertyIf your 2005 Jeep Liberty has a factory tow package, you could use either the Hopkins harness, # 42475, or the Tow Ready harness, # 118381. The vehicles with a tow package have a factory connector made to add a wiring harness. Both products will perform equally as well. But if your Liberty did not come with a tow package, you will need to use Tow Ready Custom Fit Vehicle Wiring, # 118524. This is a circuit protected powered converter which is required to protect the sensitive electrical...

This will allow you to have a connection on the front of your Jeep for a motorhome wiring connection and will allow you to use diodes to protect and use your factory wiring. This wiring kit allows you to add a 4-way flat to the rear of the vehicle for towing your boat, using the Hopkins Plug-In Simple Vehicle Wiring...
view full answer... - Trailer Wiring Harness Options for a 2002 Jeep LibertyOddly enough a tow package will not necessarily include a trailer hitch. Evey vehicle manufacturer has a different set of components that make up a towing package. The only definitive way to determine if your 2002 Jeep Liberty has a tow package is to have a dealer run the VIN number of the vehicle to tell you what options it has. f you find that your Liberty did not come with the tow package, then it will not be set up from the factory to accept the # 42475 harness. You will instead need...

The green wire carries passenger side brake and turn signals and the yellow carries the same two signals for the driver side of the trailer. If you have a left brake light signal but you are finding that you do not have a left turn signal this could mean that one of the pins inside the vehicle or harness connectors is not making proper contact...

I have attached a helpful article that explains how to install the # ETBC7 you can check out. You will also need a brake controller.

- Difference Between Curt and Hopkins Trailer Wiring for a 2005 Jeep LibertyThe biggest difference will be price. The two harnesses are basically the same harness made by two different companies. The Curt part # C55382 would be what I would go with over the Hopkins # 42475 because the price is better and because we seem to have better luck with Curt wiring than Hopkins. I attached an install video for this harness for you to check out as well.

This image shows male/female connectors included with 4-pole harness part # 42475. The 7-way harness # HM42190 also uses a rectangular OEM connector.

- Is A Separate Power Wire Needed When Installing Hopkins Wiring Harness # 42475 On 2003 Jeep LibertyThe Hopkins Plug in Simple Vehicle Wiring Harness, part # 42475, is the wiring harness you will need for your 2003 Jeep Liberty. You are correct that the # 42475 wiring harness no longer requires a separate lead to the vehicles battery. I spoke with my contact at Hopkins and he said that the Jeep Liberty never really needed the separate power wire originally, but they decided to be on the safe side and to recommend it. They did further testing and found out that the Jeeps wiring harness...
view full answer... - Recommended Wiring Harness for 2003 Jeep LibertyYes, Hopkins 4-pole trailer wiring harness # 42475 is a confirmed fit on the 2003 Jeep Liberty and is one of the three such wiring products we offer for your Jeep. However, based on our experience with all the brands of wiring products we have for your Liberty I do recommend a different option, the T-One Vehicle Wiring Harness # 118524 from Tekonsha. I recommend this product over both other options (all are shown on the linked page) because we know Tekonsha products to be very reliable...
view full answer... - Recommended Trailer Wiring Harness For A 1995 Jeep Cherokee XJThough we do have hardwire options available for your 1995 Jeep Cherokee XJ, there are no plug and play options currently available, unfortunately. If you decide to proceed with a hardwire kit, I highly recommend the Tekonsha # 119178KIT. This is a pretty quick and easy install and includes quick connectors, so no cutting will be needed. It's not plug and play, but it also isn't overly complicated either.

The hopkins wiring kit was installed on our jeep liberty and has performed flawlessly since. I tow both a boat trailer and often pull a utility trailer, so it has been used quite a bit. And, it says alot about your company that you take time a year later to follow up with your customers!
