Review: on my last outing with travel trailer I managed to mangle and sever the power cable with the hitch. I ordered this unit based on wire gauges, color codes, length, and price. upon receipt, everything matched and quality looked good. After removing old cabling and reconnecting the new one, all lights and brakes worked as before. I added dielectric grease to the connector and job is complete. I would not hesitate to order this again or to recommend it to others.

I needed to replace a cord that had been a bit beat and was a bit short on a trailer I have. This one is plenty long and had the plug built in. No trying to figure where the blue wire goes. Install was made easy and my lights work like they should.
