Review on 🔌 Upgraded Wire Harness Assembly for Muzzys HFCM Fuel Pump | Fits 2003-2007 Ford Super Duty F-250 F-350 with 6.0L Powerstroke Engine | 6C3Z-9F759-A Horizontal Fuel Conditioning Module | New Style by Chris Wilson

I needed this to replace the HFCM (one piece fuel pump assembly) on an 03 F250 6.0 Powerstroke. The original pump assembly has 3 connectors and I realized I needed a new wiring harness when the new pump arrived. I bought this because it was the right price and it arrived within a day thanks to Prime Shipping. Put the spark plugs in and the car started right away. Just one thing to note, the Ford Motorcraft build has a gray and black fork. Like this wiring harness. However, the gray harness connector connects to the black pump connector and the black harness connector connects to the gray connector on the pump assembly. It seemed completely backward to me, but that's how it is. The truck won't start if you connect black to black and gray to gray (that's how I accidentally connected it at first). It definitely worked and now the truck is running great.
