CURT 59236 Weather-Resistant Multi-Function Splice-in Trailer Tail Light Converter Kit, 4-Pin Wiring Harness, Blue, 9 x 3 x 6 inches

I installed this trailer converter kit on my 2011 retired police Crown Victoria. It works very well, though, installation took me almost 2 hours, in part because I didn't want to use the included splicing thingies that cut into the vehicle wiring, and also because the instructions to identify what type of wiring you have are not easy to follow, so I had to check and re-check until I was sure. The instructions sometimes refer to things like PS sor DS without explaining what those acronyms are, other times they actually say tail light, or brake, so it is confusing if it is the first time you do something like this. I would recommend that you get the version of this product that comes with the custom connectors if one is available for your make and model, the installation would be a breeze that way. I do recommend this Curt 59236 converter kit.

Installed on Mercedes 2010 ML350. Installation was straightforward except that since the main module has to be placed on the right side of the car, the left turn signal wire was short and I had to extend it. It would have been nice if the manufacturer had longer turn signal wires for both left and right to make it easier for users to place the module on either side of the car. Extending the cable was easy enough and the unit worked as intended. The shop wanted $150 to install it in addition of charging retail price for the unit; it takes less than one hour to install everything for a newbie!

Easier to install than I expected, mostly following YouTube video of a U-Haul install on our exact model/trim. Ran the power line inside the edge of the rear wheel well instead of toward the middle and back.

Works fine. Instructions make it seem harder to install than it really is. Well made. Just spendy for what it does.

The 59236 worked perfectly on my 2021 BMW X1, but only after some research. Grok gave me bad advice but the help line got me straightened out. Here are the technical details. The rear tail ight (where you get the signal for the adapter) have 4 wires. So is this a two-wire or a three wire system? Glad you asked. 1) The turn light is alone at the car. 2) The tail light is alone at the car side. 3) There is a brake light which has 12v with the pedal, No voltage when released, and then 5.4v if the headlights are on. 4) And of course, the ground wire. It looked like a three-wire system, but ... According to the instructions, the 5.4 volts might trigger the brake light to actuate. So does this mean my brake lights will be on if the headlights are on? Yes, unless you ignore the tail light circuit at the car side and treat it as a two-wire system. Follow the instructions closely because mine was not like the Curt video they produced for my model and year. I took the brown input (tail light) and tied it to the white wire (ground). The green and yellow inputs went to the combo voltage wires of the car's brake/tail lights (right and left). The adapter knows what to do from there. And it works beautifully. Good luck!

This product was sent to me defective. Stay away from the seller. Terrible customer service. Poor quality. Poor judgement. Stay away.

Easy install instructions were a plus and user friendly I highly recommend this For your vehicle have been a mechanic for over 40 years and it was an easy install

This kit was designed very well. I installed it on a 2007 Mercury Grand Marquis and it took me about 1.5 hours from start to finish. I would recommend it because it doesn’t add stress to the factory wiring harness because it has power ran straight from the battery.

Looks to be a good product. Just tested but not used yet. Hadn't see that it was a US type with no separation between blink and stop light. So had to buy another item to separate them to come to european norm.

2024/25 Hyundai santa fe. This trailer harness works flawlessly. More than enough wire to make easy connections and the power module is thin enough to hide behide the C pillar. *** Super important that you YouTube the U-Haul video on the wiring process, don't even try until you do and double check the the wiring you're tapping into because the left and right signal wires are both blue with an orange stripe and the brown wire with a black stripe is the running lights..... There are 4 brown wires with a black strip, be sure to test and pick the correct one. This harness is just over $100.00 but the factory plug in harness is just over $300. 00. Pick your comfort level for the install. Good luck

I'm no expert, but installing this trailer wiring kit was a piece of cake. The instructions were straightforward, and I had it up and running in no time. I've used it a few times now, and it works like a charm. A solid purchase for hassle-free trailer connections.

Facile d'installation et fonctionne tres bien!

This is the right module to install on a 2015 Golf Sportwagen TSI. All trailer lights work as they should and there are no issues to report. This gets 4 stars because of the following minor details: 1. Green wire: I wish it was at least 6" longer so that I could properly rout and secure it to the chassis. The wire is covered; thus, it's not a major issue. 2. Black wire: I with is it was as long as the supplemental black wire they provide. I'm a person who believes in minimal number of connections (crimped or otherwise) 3. Black wire routing: all instructions and online videos show drilling of holes in the chassis and running the black wire under the car, into the engine, and connecting it into the battery. I'm not prepared to drill holes in my car, so I opted for internal routing and internal attachment to the under dash fuse box (worked like a charm, but you do need the flat fuse contact from VW). 4. Instructions: they are clear as long as you know what you're looking for and know how the car taillights work. Getting to understand how the tail lights work is the key to properly wiring the module.
