Some trailers still use older incandescent lights that draw more power than modern vehicle wiring can handle. This harness solves that by using a powered converter that draws power directly from the battery through an inline 10-amp fuse. It keeps the trailer lights from overloading or shorting out your vehicle’s tail light circuits, protecting your wiring and electronics no matter what kind of trailer lighting you use.
Wiring a trailer doesn’t have to mean cutting or splicing factory wires. The Curt T-Connector plugs in behind the tail lights using OEM-style connectors, making installation clean and direct. The harness gives you a 4-flat connector ready for running lights, turn signals, and brake lights, all while keeping the vehicle’s wiring intact.
By running a single power wire to the positive battery post through the included fuse holder, the harness provides a dedicated, stable power source just for the trailer lights. That steady feed helps prevent flickering or weak signals and protects the system from voltage drop that can happen when pulling power through the tail light circuits.
The converter box is designed to handle the current draw from both LED and incandescent trailer lights and isolate the vehicle’s wiring from potential shorts on the trailer. Even if the trailer wiring has corrosion or a bad ground, the harness’s own fuse will blow first, saving the vehicle’s fuses and electronics from damage.
Once installed, the 4-flat connector covers all the basic trailer lighting functions—running lights, left and right turn signals, and brake lights. It’s the standard plug for small and mid-size trailers and works with most trailer light kits, so you can hook up and go without adapters or extra wiring.

Was impressed with the quick ship time and once I opened the package, I could tell the quality was definitely there.I also like the instructional video. That was very helpful.
Thank you
Product came with everything you need. The time line that other customers had put in their comments were off. It was pretty easy to install, just trying to figure out which way to run your wires was my biggest problem. Otherwise, I am very pleased with the product.
The instructions could be better but I watched the YouTube video and it’s pretty self explanatory
Great product, great price & very FAST shipping.
Will definitely buy again!
I found this item to be very easy to install and the instructions very easy to understand.
Had to watch the installation video but it was flawless and works great.
Installation was not complicated the product looks good on the vehicle, and should serve its purpose towing well.
Shipping was very fast, the instructions seem to be easy enough, however I haven't had the time to install it yet.
This is the second set Ive got; was impressed with the kit I installed and use for a the Ford Transit. So when my father got a small boat. I already knew where to go and who to trust for wiring his PT Cruiser correctly and with relative ease. Props on those videos; they are thorough make it easy for even me to see and understand.
This wiring harness worked great. The instructions were good, and their instruction video was a big help.
Following the video I was able yo to do the install myself with minimal issues. I didn't have the advantage of a lift as the video shows, but backing my car up onto ramps gave me enough room to squirm around underneath. Works great!
The wiring harness adaptor has worked great without a glitch for over a year now.
Excellent CURT product with easy DIY instructions ( also on-line video)!
etrailer.com equals Quality products!
I purchased trailer wiring for my 2005 PTCruiser. I had it installed in less than a half an hour. Great product. If I ever need another one , I will definitely purchase from e trailer.
I just open the box and surprise here's the light kit. this is going to make it very much easier for me to hook up the trailer lights. It's raining right now but when it stopped I'm putting everything on this car that I need for my job.......
thank you very much
The instructions could have been a little clearer. Other than that, everything is great. Thank you. Sincerely.
Directions that came with this harness were useless, but I did find the video on the web site very helpful. I installed this on a convertible, not a sedan as shown in the video, and could not run the wire from one side to the other the way the video shows, due to an obstruction in the area behind the left taillight. It took several tries to find a route for the wire that worked, due to the yellow wire being about 6" too short. Because of this, it took me several hours to install, a lot more time than I expected. A few extra inches on the harness to the left taillight would have made this job much simpler.
Yes I did get the package for the trailer wiring harness. I bought one a while back and it went bad so I bought another one and it has gone bad also. And that is why I bought this one. Not very happy with the quality. It seems the controller goes bad inside.
This connector replaced a seven year old connector that had the power wire break inside the potting. Installation was completed in less than a half an hour. One connector did not lock into place but still provided an electrical connection. If installing for a first time, it will take longer to run the power wire from the battery and other routing other wires. Simply put, it works.
I also had great customer service from Courtney B as well as prompt delivery from the US Postal Service.
all connectors and misc hardware was included to complete the installation. Nothing extra was needed. Two glitches haowever:
1. It's a good thing I watched a YouTube video before starting, because the instructions read backwards as to the starting steps. (You begin on the "passenger side", not the "driver's side")
2. The yellow wiring that crosses over from passenger to driver side is One Foot too short. Despite taking care to route it the shortest distance possible, I was just able to make the final connection to the driver's tail light, and therefore, not able to mount the module on passenger's side with the "sticky tape" supplied, as the module is too far down in the space to fasten to any surface. One more lousy foot of the cross-over wire would have made life, and the installation, much better. (the 12gauge wire that is routed forward to the battery had 2' to spare)
Product went in quick and easy and works as it should. The only thing I would change is having a tab with a hole on the box so that it can be securely mounted to the frame. You have to run the long wire under the car to the passenger side towards the front of the vehicle to avoid crossing the exhaust but it works out well with their being an extra spot in the plastic clips that mounts brake lines to the undercarage. It keeps it looking neat and you don't have to worry about the wire dragging.
Easy install but you will need something to fish the wire from the right side to the left side through the bumper reinforcement. I used 2 coat hangers hooked together and it worked fine. Running the power wire to the front is the hardest part of the install and if you have a friend with a lift it would make it go much faster, but it can be done with ramps and a jack and jack stand. Took about an hour.
I needed a new wiring kit because original kit's power converter failed such that car's tail lites were on 100% of the time; draining my battery overnite, twice, before I finally disconnected power from battery. Nothing else would turn off the tail lites. Several issues where replacement kit fell short of original wiring: no labeling on power conv module for leads; plug-in connectors were somewhat mis-shapen and were difficult to plug in to car's tail lite harness; orig kit came with pre-installed spade conn for batt wire to module, this kit did not, and since I did not run a new batt wire, had to splice new spade on conv to attch to existing batt wire; yellow wire to driver-side tail lite was too short so I had to splice in an add'l length of wire; finally, original kit dbl-sided tape mount of conv failed (and may have contributed to conv failure as it was bouncing around in tail lite housing), and new kit came with same, so I fab'ed a more permanent mounting bracket. Once all was installed, all my lites on car and trailer work OK.
I ordered this for my PT Cruiser and it went on with no drama at all--perfect fit, easy to install, and I've taken it on the road with no trouble at all. Very well made. One thing--if you don't have access to a lift, you might want to consider taking it to a shop and having it put on for you--especially if you're over 40 years old and installing the Curt hitch at the same time. There's absolutely nothing wrong with the design or the installation directions for any of the components--it just takes a lot less time and effort if you don't have to jack the car up on stands and do the limbo for a couple of hours. If you have a lift handy, I'd guess the install would take less than an hour total for both wiring and hitch. I'd also recommend holding off tying everything down until you've got all the wire run out, that way you can adjust things as you go. I also took a moment to plug in the jumpers on the assembly to the tail lights on my car and test my vehicle signal lights before hauling out the rest of the wiring and hooking it up to the battery and trailer. This verified (before I got too far into the job) that the module works and there's nothing wrong with your car's wiring (my PT is 11 years old and the plastic socket for the turn signal light is starting to degrade--had to replace it.) You wouldn't want to get everything all hooked up and then discover a problem--test as you go and you'll be fine.

Just installed the Curt hitch on my wifes 2001 PT Cruiser. Started that job on Saturday, then took a break, intending to finish it after watching the Jacksonville Jaguars-SF 49ers game from London. After watching the early part and realizing the Jags were going to get badly waxed AGAIN, I was feeling depressed, so I DVRd the rest and headed for the garage to work on the hitch. Completed the installation, having never installed a hitch before. It worked like a champ, I was satisfied, and my depression left me. Unfortunately, it appears Ill need an every weekend project to complete as long as the Jags are playing this season.Im now rehearsing what needs to be done in the wiring harness arena. Sounds like I can handle that also. Thanks for the encouraging comments.
