The Uriah 4-Way Flat to 7-Way Blade Trailer Electrical System Adapter is a versatile wiring solution designed for vehicles equipped with a basic 4-way flat plug that need to tow trailers with a 7-way RV-style blade connector. This adapter allows you to bridge the two different systems easily, and it includes additional wire leads for auxiliary functions. These extra wires enable you to connect essential features that a 4-way plug does not support, such as electric trailer brakes, a 12V power supply for a battery, and reverse lights. It is an ideal upgrade for SUV and truck owners who are moving up to larger campers or car haulers.

When installing this adapter, the additional wires must be manually connected to your vehicle’s wiring system to enable the full 7-way functionality. Typically, the blue wire is for electric brakes, the black wire is for 12V battery power, and the yellow or purple wire is for reverse lights. It is important to use a circuit tester to verify your vehicle’s wiring before making these connections to avoid blowing fuses. To maintain the life of the brass terminals, apply a small amount of dielectric grease periodically to prevent the green oxidation that can cause intermittent lighting failures.
