Custom hitchesA trailer hitch receiver is the starting point for most people looking to tow with their vehicle. CURT offers over 1,000 different custom hitch models to provide a perfect, factory-like fit on most vehicles on the road today. Our custom hitches provide a standard hitch receiver to mount a variety of towing accessories. |
Vehicle-trailer wiringThe next step in equipping your vehicle for towing is to add a trailer wiring harness. Like our hitches, CURT custom wiring is made vehicle-specific for each make and model. Virtually all of our custom vehicle-trailer wiring harnesses install using existing factory connectors on the vehicle for a plug-and-play connection. No splicing necessary! |
Ball mountsWith a custom trailer hitch receiver installed on your vehicle, a variety of ball mount options can be installed as needed. We offer loaded ball mounts with a trailer ball already torqued in place, as well as adjustable ball mounts, multi-ball mounts, tow hooks and more. A ball mount can be secured into the receiver using one of our hitch pins or hitch locks. |
Cargo managementTo add cargo space to your vehicle, CURT offers a number of cargo management accessories. Our cargo carriers are available in a convenient, use-as-needed hitch-mounted design, as well as a roof rack option. We also offer bike racks, cargo bags, cargo nets and ratchet straps for additional item security. |

To install a 5th wheel hitch in your pickup truck bed, CURT offers traditional 5th wheel rails and brackets, as well as puck system options and gooseneck adapters. |
Gooseneck hitchesFor towing heavy-duty trailers around the farm or out to the construction site, CURT gooseneck hitches are a highly dependable extension of your truck. We offer puck system gooseneck hitch kits to accommodate trucks with the factory towing prep package. We also offer original-equipment-style gooseneck hitches for select applications, as well as traditional gooseneck hitches and brackets, such as our original Double Lock. |
Trailer brake controllersCURT offers several different electrical trailer brake controller options to perfectly suit your towing setup and lifestyle. Our Echo mobile trailer brake controller is particularly unique, featuring a Bluetooth connection that links to your smartphone and provides highly responsive braking with your Apple or Android device as the interface. It easily plugs in with no tools or extra wires needed. We also offer our factory-like Spectrum and traditional TriFlex. |

Weight distribution hitchesGive yourself more control over your vehicle and trailer with a CURT weight distribution hitch. This receiver hitch attachment helps level the vehicle-trailer combination for a smoother ride. Our TruTrack weight distribution hitch is particularly unique, featuring integrated trailer sway control. |
Pintle hitchesThese heavy-duty hitches are perfect for agriculture, construction and military towing. We offer pintle hitches, pintle hooks, ball and pintle hitch combinations, as well as channel-mount pintle hitches for an adjustable option. We also carry high-strength lunette rings for a solid connection to the trailer. |

Product Description
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 RV blade connector is designed to supply power for tail lights, turn signals, electric trailer brakes, a 12-volt battery, reverse lights and brake lights, as well as a ground connection. It features rust-free black plastic construction and is a male-end plug, specifically designed for the trailer side of the connection. 7-way RV blades are typically used on RV travel trailers, and this particular connector can be easily interchanged with other 7-way RV connectors.

My biggest concern was that the wiring mapping wouldn't be correct, but I used the old plug as a check and the supplied diagram (and printed guides in the plug itself) were exactly the same for this US made trailer.
Highly recommend.
