Review on 🔌 Hayes 81789 Quik Connect Universal Wiring Harness with Dual Mated Design & 4 Wire Leads by Timothy Harper

Summary: Excellent quality, just what is needed to install a custom Hayes brake controller. This high quality pigtail setup plugs directly into the connector on most new Hayes brake controllers. You will need this item if you received the controller without a connector cable and you cannot use any of the "big three" connector cables to connect Ford, GM or Chrysler. You should use one of these cords if your car has a suitable outlet as it simply plugs in at both ends. This item works when there is no outlet in the car and you need to plug it in yourself. The end of the controller connects and the other end connects to the car trailer wiring if needed.
