## 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 4-way flat connector is designed to supply power for tail lights, turn signals and brake lights, as well as a ground connection. It features durable rubber-molded construction and is made with 12" of standard color-coded, bonded loop wire to easily splice into your vehicle's wiring system. It includes both a vehicle end and trailer end and can be cut to splice into existing wiring or left as a loop to serve as a useful extension harness. It is compatible with all 2-wire vehicle systems.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 🤷🏼‍♂️
*by C***R on March 24, 2025*

Works as expected

### ⭐⭐⭐⭐⭐ Cheap and worth it
*by J***Z on March 31, 2025*

Great product for extending trailer wires. I bought one for each vehicle just incase I need it. Cheap enough to afford to do so

### ⭐⭐⭐⭐⭐ Just what I needed and the price is right
*by E***N on January 19, 2025*

I needed an extension for my new truck that has a ridged harness mounted on the hitch. Rather than modify all my trailers, I just permanently attached this to my harness adapter on the truck.And you can cut off either end if you need a new plug for a truck harness or a trailer harness (or both)
