## Description

Rain, road grime and salt can deal a vicious blow to your trailer wiring, and it takes electrical components with an extra-thick shell to stand up to the elements. The CURT multi-function electrical converter is an advanced taillight converter that offers the ultimate in vehicle compatibility and weather resistance, giving you a reliable wiring connection any season of the year. The potted design seals the internal electrical components in a watertight enclosure and is filled with a solid compound to protect against impacts, vibrations and moisture for long-lasting use, even on the exterior of the vehicle. The converter also features our advanced surface mount technology (SMT), using smaller components mounted directly to the surface of the circuit board. This produces lower resistance, reduced heat generation, longer life cycles and higher reliability. The CURT multi-function electrical converter comes with pigtail wires that are able to be spliced into two-wire, three-wire or PWM wiring system with combined stop and taillights. It converts any of these systems to a simple two-wire system, using a standard 4-way flat output, to be compatible with most trailer wiring. The converter is controlled using a microprocessor that is able to sense the current passing through it, allowing for quick reaction to dangerous conditions such as overload and short circuits. It also filters unwanted input signals to protect your wiring systems and uses a mere seven volts for low-voltage operation. The CURT multi-function taillight converter is a heavy-duty electrical converter for virtually any vehicle-trailer combination. It comes with color-coded wires and an easy-to-read wiring guide, as well as a dust cover to protect the 4-way flat connector. This package includes a powered converter wiring kit #55152 and four snap locks for faster, more secure splicing.

Review: Works great, high quality, right wire gauges, solid/sealed converter. Installation is NOT trivial - 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.
Review: Good price, easy to install! - 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
*by M***A on March 15, 2026*

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.
