This harness provides a plug and play upgrade solution for those seeking to convert to Coil-On-Plug. Additionally we have pre-installed a Power Tap for easy access to 12v, 5v Reference, and Sensor Grounds. The Ford MPFI C-O-P Main Harness has also been pre-terminated for the stock Pulse Width Modulated Idle Air Control motors commonly found on Fuel Injected Windsor 5.0L engines.
