Nilight Heavy Duty 7 Way Inline Trailer Plug 8 Feet Connector Cable 7Pin RV Round Extension Wiring Harness Weatherproof Junction Box for RV Towing Car

Not sure why people are complaining about colors not matching up it literally comes with the color coded plug diagram easy to install good fit would buy again

I bought the 16' very NICE qualityAlot better than expected.will buy again.

I did a restoration on my trailer last year and while this seemed too good to be true, this connector has been flawless. I made sure I made a good ground connection with the trailer and I've had no issues out of it at all. The previous connector had a weak ground and my truck constantly thought it was disconnecting. As others have probably mentioned, the color coding of the wires is not standard but it comes with a diagram or you can use the guess and check method.

Easy to install the junction box is great. However the hard outer cover on the harness is too stiff for cold weather conditions and a serviceable plug would be better.

Good quality product that is very useful on any trailer for wiring solutions. However, the color codes are not the rv standards. The labels are correct to what is wired in the plug just colors are not what is standard for turn signal wires and running lights. Good crimps, good rubber seals, good plug.Read labels, don't go by standard color code

works as it should

I was very impressed with this trailer wiring kit. I bought this to convert my new trailer from a 4 pin plug to a 7 pin plug as I was adding back up lights and electric brakes. I unfortunately didn’t pay attention to see that was made for an RV, but that was easily fixed. Remember that RV and standard trailer wiring are not the same. The wiring configurations are just a little bit different. This is a high quality wiring kit. The cable is very heavy duty. I expect this will last a long time.

I used this to convert my trailer from the factory 4-pin to a 7-pin setup. I wanted to add reverse lights. This kit worked perfect!
