Additional Information

When your vehicle does not readily provide an electrical connection for hooking up your trailer, CURT electrical converts offer the solution. Working tail lights on your trailer are absolutely essential any time you tow, and a converter provides an effective way to properly equip your vehicle for safe towing.

A CURT electrical converter, much like our custom vehicle-to-trailer wiring harnesses, provides a trailer connector on your vehicle by slicing into the vehicle's electrical system. Electrical converters are designed to splice directly into the taillight wiring, rather than plugging into various sockets, giving them the nickname "taillight converters". Though it requires a little extra work compared to a custom wiring harness, a tail light converter offers a reliable, long-term connector solution.

This CURT electrical converter is designed to convert a 3-wire system to a 2-wire system and provides a standard 4-way flat connector socket to plug in your trailer. This converter is made with cutting-edge surface-mount technology (SMT) circuitry, featuring electrical components that are mounted directly to the surface of the board rather than being inserted into a series of holes. SMT circuits have longer life cycles, lower resistance, reduced heat generation and are more reliable than through-hole-mounted components. Plus, to give you peace of mind for the long haul, the majority of CURT converters are proudly made right here in the USA.

curt 59146

I ordered this from Summit Racing, and installed it on my 03 grand caravan, very easy to install, and looks nice. The down side to it, before I put in the fuse, I took it to my local auto body shop and everything was wired and functional as it should. When I hooked up my trailer and went 26 miles the right hand side, turn and brake light quit working. Took it back to the body shop, and there is nothing wrong with my trailer. So and the curt 59146 was still wired and everything just fine. I don't know if I got a bad one or what happened

More specific info would help...

Nice kit, and complete. Unfortunately, I still don't know if I've wired it right on my 2009 Prius, since it seems that the red (brake) wire has no place to go, and the car lights work w/o out it. Haven't tried hooking up the trailer yet. Curt should add a web page with specific hints for specific cars, as feedback like this comes in. Indeed, I hope that Curt sent the right kit (59146) to go with the 2006 - 2009 Prius!
