Hopkins Active Tail Light Converter with Install Kit

Excellent. The only down side for my Lexus RX300 was not having an “easy” way to mount male 4-way next to hitch rather than stowing it beside tire bay. No big deal just a plus.1747794

I have ordered from Etrailer several times over the years. Always have exactly what I need. Good prices and fast shipping. Could not be happier. This wiring harness was perfect. Installed it in a few minutes.
Thanks.1774393

I received this product the other day and went to work installing it on my 1993 Jeep Grand Cherokee Laredo. This was done outdoors on a sunny 90 plus degree day on [the driveway].

Prior to buying I had read the online instructions and, more importantly, watched an installation video. The video was a huge help and the kit was very easy to install. The snap splice connectors work like a charm. I used extra zip ties I had to secure the power line in place as I routed it down the passenger side of the Jeep. Hook up to the battery terminal was easy.

I did not have a circuit tester to check the individual wires to ID their function but since their colors exactly matched the video, I decided to take my chances. It worked out great.

Installation of the power wire would be easier on a lift but I don’t have one installed in my driveway so it entailed crawling under the678417

Hello Carol,
I installed it as usual but it did the same thing than a previous one. The only light that worked were the tail lights. Tested all incoming wires - were all connected. Fortunately I still had one that I got from you a couple of years ago which worked fine. Please be so kind and send a return label. Thank you very much for all the great service I received from you over the years.1560075

Converter worked fine was not easy to install to existing wiring. Running the battery lead was very time consuming .1639601

The product is as described. I installed this on a 2003 Toyota Avalon. I took the time to research the factory wire colors, and I was reasonably successful.

There are two wires into each blinker light housing. A green and yellow wire and a black and white wire.

The black and white wire is the emergency flasher. The green and yellow wire is the blinker. Resist the urge to overthink it, both blinkers are green and yellow wires.

I chose to wire everything to the drivers side of the vehicle. The reasoning was that there was sufficient power wire (RED) from the isolator to go from the drivers side rear blinker to the battery in the forward end of the engine compartment. There is also sufficient wire (GREEN) for the passenger side blinker. I routed everything through the factory wire chases by removing the trim pieces (no tools required) and removing the back seat. You can easily follow the factory wires. Since I mounted the isolator inside the left blinker trim panel, all the other wires were sufficient to connect the brake and driving lights. I hooked up the ground (WHITE) to a bolt that holds the rear lamp assembly in place. A 10mm nut was readily accessible for this.

I searched high and low for a location to run the power wire through the firewall. There is no factory spare that I could find. That being said, I decided the best location to drill a small hole was near the accelerator cable. This area provided plenty of clearance to avoid any other component.

I used some rubber insulation material and a little bit of plastic as a chafe guard in the hole. Zip ties competed the job, and it looks like a factory installation.

I tested the lights by hooking up to a trailer with a 4 pin flat connector. Everything worked perfectly.

This is a good product, although my interior installation method is far superior to running the power wire under the body, along the frame rails, next to brake lines, etc.

Take your time and run the wiring where it belongs, inside the vehicle.

Incidentally, I let the connection pigtail for the trailer to stay inside the trunk until I need it, then it can drape across the weatherstripping and outside the trunk with the lid closed. No pinch. There is sufficient wire to do this easily.1485877

If you need help with finding a trailer hitch, look no further. I have a Volvo and was looking for a trailer hitch. I contacted the dealership and was put on hold for 30 minutes. They said that they would call me back, never did. I then called etrailer within 5 minutes my order was placed. I received my hitch 2 days later.This is a no nonsense business, that believes in the customer. I highly recommend this company and will use it for future use.1515572

Great product. If you don't have a friend to help you align the hitch during installation, a floor jack is very helpful. When using the fishwire for the first time just be patient, it takes a little time to get the hang of it. Also, I ran the harness through the car underneath the carpet and up through the side kick panel to the battery rather than underneath the car. Mazda 3s are low enough already to worry about a wire harness coming down underneath the car. Just spend some extra time and do it right.488386

Great. Still works just fine.

I ordered a ball, ball mount, Curt Hitch and Hopkins Converter kit for the lights. My order was potentially delayed due to the ball I ordered not being in stock. It arrived within the shipping time quoted. Without the required hitch pin to hold the ball mount to the hitch.

The Curt hitch bolted right up. And looks fine.

The Hopkins converter kit is a complete joke. The website said it was for my vehicle, which it is.. The only problem is, the wiring connections are a joke when a simple adapter could be used to do all of the tail light connections. (Running lights, brake lights, right and left turn signal are all wired to a simple connector on the drive4rs side. 3M connectors make me nervous! They make adapter plugs for many for other vehicles, never saw this option offered by Etrailer. I hope to receive the hitchpin by the middle of this week.

If we are required to use a 3M connector, you should at least supply the silicone dialectric grease to complete the job.555267

The hopkins wiring harness part # 46255 is a universal wiring kit. Currently, there is not a plug and play option for a 2004 Buick LeSabre. This kit does include a small packet of dielectric grease but if you need more I recommend part # 11755 2 oz dielectric grease.

Before installing Hopkins Active Taillight Converter kit 46255 I didn't have any trailer stop lights. After installation all trailer lights worked perfect. S.L.102223

Works perfect. Great product.

Very easy install in my 2011 BMW with no issues. Was worried of having bulb faults with a European car but was perfect!1646018

This piece of junk worked when installed, but only briefly. I rarely use a trailer but need the lights to work reliably when I do. Probably about the third or fourth short trip the internal electronics fried themselves and the switching inside the unit failed, leaving one light on all the time and the other not working at all. This was using the most basic configuration of trailer lights - just two #1157 bulbs, that's it. No possibility of overloading the converter, which was located inside the hatchback area of the tow vehicle, hardly ever used, and not out in the weather. The failure occurred just at about 7 months of ownership, etrailer refused to stand behind the obviously defective product since the warranty is only 6 months. Really, for automotive use, a product should last years. Two thumbs down.1025619

Installed on a 2009 328i BMW, took more work to get interior panels off/on in trunk area than the wiring. I had the electrical wiring diagrams for the car which really helped.263249

Just went camping hooked up trailer and all lights worked as they should great product.

The only thing that would have made installation easier would have been if the tail light harness instructions would indicate for the car model which color car tail light wires to connect to on each side. Took some experimentation to figure it out.1454326

It worked great! It was exactly what I needed1634863

I bought this for a 2004 Buick Lesabre limited, so I could pull small trailers and someday a small boat. It's somewhat easy to install. Once I figured out the purple wire in the car is for the tail light on the converter box, it was all good. Anyway, it does what it's supposed to, which is amplify the power to the trailer lights, and it does it very well. This product will ensure your vehicle's electrical system will be safe under the extra load of the trailer lights. The only issue I had was figuring out where to mount the converter box, and had to get creative. I think using a strong adhesive to stick it to the inside wall of the trunk would be the best option.227903

One year in and the wiring harness is still working great. I had to reset the in-line fuse once because the trailer lights were not functioning, but that was a 30 second fix. Pop out the fuse, pop it back in. Done. 619190

Good directionstuff to be helpful. The installation to be easy. Took me about 1 hour to complete and working flawless when done.196910

Works great. No issues

I ordered this product even though I didn't need it to make the trailer lights work properly. I bout it in this case to isolate the vehicle and trailer lighting system from each other. With computers controlling everything on modern vehicles a short in trailer wiring could cause the vehicle to stop running when it sees a problem. I did need this same item on out Jeep Liberty to make the brake and turn signals work.
etrailer is my go to place for towing items. Good prices and fast shipping. Good customer service too. A cheap price is no good without good customer service.699557

As usual my experience was nothing short of amazing! I need to replace my trailer wiring harness on my ‘05 ML500. Ashley answered my call, heard & understood what I need along with any extra items. She even looked up my similar purchase from 3yrs ago to be sure we had the correct items for My vehicle! Fantastic Friendly & fast service! We had the order placed in less than 5 min & had a confirmation & notice of order complete & ready to ship within 2hrs! Shipped the next day & I received the goods on wed.!
THANK YOU ASHLEY!! And THANK YOU ETRAILER once again for fantastic service!853018

Easy to install. After that it kept blowing fuses left and right. It was rated for the trailers I was pulling so i was quite disappointed. Soon after the wires overheated and started creating smoke inside the vehicle so I removed and replaced with a different brand.467923

The unit went on reasonably easily except for running the power wire up to the battery. That part was a pain, but oh well. I did encase the power wire in plastic loom and then rubber hose once I got to the engine compartment for protection of the wire just to be safe.915749

Thank you for following up with me. I would first like to say your customer service is first rate. The hitch and wiring harness are great too. Install was fairly easy and instructions good. The only minor problem I have is that the trailer ball I purchased and used on the trailer began to rust last fall. Probably my own fault for going through the car wash too many times with the hitch in. Anyway, thanks again for the follow up. 477506

The wire on the B+ wire to the battery was about 3' too short necessitating a trip to the auto store for a $7 roll of new wire. Other than that, wiring package was easy to install. I would think the wire would be too short for most installations and for the price of the kit, they need to make longer. 228398
