Review on 🔌 Custom 4-Pin Trailer Wiring Harness for Ford Crown Victoria, Mustang, Grand Marquis – CURT 55326 by Shafiq Wang

Very easy to install following the instructions but as soon as I checked my headlights my left hand sign started flashing rapidly as if the bulb had burned out but the side marker light also flashed. everything is back to normal. I turned on the test lamp and found that the wiring harnesses from this unit were misplaced. In the socket that connects to the car's wiring harness, the yellow (signal) wire is in the top right corner and the (parking light) wire is in the bottom right corner. However, the connector that goes to the tail light and side marker has the yellow and brown wires reversed, so the brake/pivot wire is trying to power the side marker and the brown side marker wire. try to feed the stop and turn function. You might want to test this quality control in your Mexican factory and make sure the assembler is not color blind.
