Review on 🚚 Heavy-Duty 4-Way Flat Trailer Connector with Self-Closing Lid Cover - 12V 4-Pin Tow Wire Harness Kit with 7.8" Wires and WeatherLock by Dave Hunt

This product is of obviously high quality. BUT I can only give 3 stars. The installation guide ONLY tells you how to mount the hardware. There is no explanation at all about the wiring. I went to erich-jaeger-usa.com to find detailed instructions/diagrams. This is a huge company but their search function sucks. I've tried every nomenclature I can think of, including those listed on the packaging. Not found. I've tried every number. Not found. The company seems to be taking the position that its customers already have all the connectors installed. The site was probably designed by engineers.
