Review on 🚗 Enhance Your Ford Transit Trailer Wiring with CURT 56327 Vehicle-Side Custom 4-Pin Harness by Scott Yenson

The whole process was easy to follow and the guide was easy to understand. The last thing needed is the black box going to the battery. This is where the process really went wrong for me. I think I may have had a broken box because everything worked fine and as advertised until the black box was installed. I installed as directed and even used a separate car battery but it didn't work. This product has a lot of great reviews and I hope it was just my box that was faulty.
