Your cart is empty.Like trailer hitches and ball mounts, electrical connectors range all over the board in shape, size and capability, but no matter what your trailer's electrical functions are, you need a solid connection to keep the power flowing and ensure safety on the road. CURT electrical connectors are designed and manufactured to give you a reliable connection every time you plug in your trailer. This 7-way round connector is designed to supply power for tail lights, turn signals, electric trailer brakes, auxiliary power, reverse lights and brake lights, as well as a ground connection. It features durable die-cast metal construction and is a male-end plug, specifically designed for the trailer side of the connection. It also features a spring attachment to keep wires well protected. 7-way round connectors are commonly used on RV travel trailers, and this particular connector can be easily interchanged with other 7-way RV connectors.

Rugged design to hold up to agricultural use. Works great.

The majority of trailer plugs use a screw to connect the inside of the plug with the body. These use a spring latch, we have had issues with the latch not holding and the guys pulling the plug apart. This leaves the connector inside the plug and a bunch of wires in your hand. Great value for the price, the quality otherwise is great. We use these in a commercial application, going to switch to the version with the locking screw.

I purchased the CURT 58180 Trailer-Side 7-Pin Round Wiring Harness to connect my trailer to my vehicle, and I'm extremely satisfied with it. The installation was a breeze thanks to the clear instructions and well-designed connectors. The harness fits perfectly, and the quality of the materials is top-notch. If you're looking for a reliable and easy-to-install trailer wiring harness, I highly recommend the CURT 58180.

Seems to be of good quality. Never used the Curt brand on the big truck though. Just going to lather on some grease and let it ride. Should be fine for light duty non-commercial use.

Replaced my old plastic one on my semi with this heavy duty metal one, the build quality is perfect, solid and it has bigger screws so connecting the wires is so much easier.

Great replacement for the older style RV round pin (NOT blades) trailer connectors. Wire designations are marked inside next to the screw terminals. Good housing and strain relief for wires. Heavy and heavy duty.

Not a good quality product. Made in Taiwan and the fit is so loose in the female socket that the trailer lights don't work properly.

This item solved a problem with lights on our trailer. Worked very well and fit perfectly. It takes care of the problem with very little expense and came very quickly.
