I recently purchased the Adullama 4 Way Trailer Wiring Harness, and I’m very impressed with its quality. The 5ft jacketed wiring provides plenty of length for easy installation, and the wires feel durable and well-made. It’s a perfect fit for my trailer, and the colors are clear, making the wiring process quick and straightforward. The connectors are sturdy and fit securely, so I don’t have to worry about them coming loose while driving. Overall, this wiring harness is a great value for anyone needing to upgrade or replace their trailer’s wiring!

i like this a lot. Cable was heavy duty and looks like it will last much longer than the standard flat cable style

One of the leg of the connector un-hook from the main plug, and its not because i was hard when i used it, and its not because the car plug was old (brand new toyota)Get someting else otherwise you will have to redo your harness in no time...
