Review on 🚗 Custom 4-Pin Vehicle-Side Trailer Wiring Harness by CURT for Ford Explorer - Model 56172 by Jason Arkin

I originally wrote a good review about this product. I wrote that it was easy to connect and all my lights, backup camera and alarm worked as before. Actually I didn't manage to connect anything to the 4 pin connector because my plans changed and I didn't use it as planned. Well, three years later I bought a trailer tent and plugged it in and it didn't work. . First I found and repaired a broken wire under the plastic cover. The only thing that worked were the parking lights. Blinkers and brake lights didn't work. After spending a whole weekend trying to find the problem, I unplugged it, bought another brand and tried it immediately. I know it was probably my fault for not testing it, but it's a reputable company so I assumed it would work.
