Worth every penny even if you’re experienced in splicing wires
Product arrived next day after order. Very easy and fast to install. Perfect product for someone looking to install any kind of light bar, camera or truck accessory.Completely eliminates the need to cut into your factory wiring harness, additional 4 pin connector let’s you simply plug in a light bar without having to splice into the harness or have the wiring hang out of your trailer connector.The only improvement I would like to see is for the reverse light wire of this harness to be lengthens by a few inches because this is the only wire you need to splice in order to connect the reverse light wiring for a light bar or backup camera. Still fairly easy to do but a long reserve light wire would make this product perfect!

Excellent for Reverse Tapping for Light Bar
I bought this to use as wiring to tap into the reverse light on my OPT7 Paralux Triple LED Light Bar. The light bar comes with the reverse wire separated and you have to tap into your vehicle someplace to make the reverse light work. This harness was the answer! Instead of tapping into the taillight or factory harness I wanted to use something that would be just as effective without forever splicing into the factory wiring. After reading forums I found this very harness as a recommended alternative. The vehicle I perform this method on was a 2017 Ram 2500. The lightbar wiring length was not generous and so having this harness saved the day as the trailer plugs are on the passenger side of the truck…while the lightbar wire didn’t reach all of the way! Good thing I got this harness. There’s some nice videos on YouTube for installing this Curt product. It’s relatively simple; I didn’t have to take off the spare tire. Apply dielectric grease and plug it in! Route your wires and test first before securing them or tapping into the wires for any reason. Another benefit is the wires fromAuxiliary wiring such as with the LED lightbar are nice and hidden and don’t come around the bumper and plug in. Now there’s more room for the use of the trailer harness! If you do use this to tap into the reverse wire, the reverse wire is the middle white wire….the one right in the middle! Good luck and enjoy!
