Universal Short Proof Power Converter by Hopkins®. When attaching a trailer to your vehicle, a premium quality wiring kit or harness is a vital necessity. An automotive trailer must have a reliable connection with the signaling system of your car to operate properly.

Almost any trailer features a specialized electrical plug, which connects it to the towing vehicle's electrical system. Still, there is a number of automobiles that do not have a matching electrical socket. Fortunately, aftermarket trailer wiring kits can be installed to interface with the trailer plug. Our website is proud to offer top-quality and high performance wiring kits and harnesses by Hopkins to satisfy all your towing needs.

Wiring for your trailer can be as easy and quick as plugging in a USB stick. If it's hard for you to believe that, it's high time you got acquainted with the Hopkins Towing Wiring Harnesses and Kits. These extremely effective add-ons come equipped with OEM connectors to ensure a snug, weather-tight fit, and are made of heavy-duty materials to withstand the rigors of heavy towing. Also, each and every kit comes complete with all necessary hardware and easy-to-follow instructions. Instead of using a wiring harness that requires you to cut or splice into your existing tail light wiring, go with the Hopkins plug-in style wiring harnesses to save both your time and effort.

With over 60 years of invaluable experience, Hopkins® is recognized to be the automotive industry leader in providing exceptional quality towing electrical products. Since the company's early days, it has been guided by the philosophy that all the parts they create must deliver meaningful innovation, value, and performance to the client. According to the company's current rating, they seem to have succeeded in achieving their goals: today nearly 40% of all towing electrical retail sales are proprietary Hopkins innovations. To generate such great results, the manufacturer employs more than 500 people on two production facilities.

Hopkins Trailer Converter For Infiniti
Hopkins® - Short Proof Power Converter
Instructions were concise and clear. Unit does not go through the cars ignition wiring, so is on all the time. Current draw? Why not wire to 'hot' wire activated by ignition being turned on.

ML 350 2011 Hitch Wire Harness
ML 350 2011. Wire harness was complete. This took a little longer to install than I thought do to fishing the wires through the car. I did add an inline fuse, just to protect the electrical system.

Wiring Harness Installation
Simple to use & easy to install. Only thing not covered was testing, if you don't have a trailer to test you need to ground out the ground plug on the male plug.

This harness is perfect for towing. I bought it from Carid.com and it arrived quickly. There isn't much else to talk about other than it is everything it is advertised to be.

Good deal
This trailer hitch harness works great and the pulley system worked perfect. The harness is built very well and looks like it should work for a long time.
