Review on Enhanced Fuel Pump 🔌 Wiring Harness - Delphi FA10003 by Kevin Hutchison

This wiring harness was received quickly and is required when replacing old fuel pumps on GM vehicles as the electrical connection on new GM fuel pumps has been redesigned! I used this with my new Delphi FG0273 fuel pump which I also bought here on Amazon. Excellent Quality OEM Product! The reason for only 4 stars is this: Buyers beware I installed this on a 2002 Cadillac Escalade, this wiring harness comes with several instructions for color coded wiring options and none of these were the right option for my car when I got this one new Plugs into the car's wiring harness and you didn't have a chance to know until the installation was complete and the new fuel pump didn't work. So if you are doing this install on the same car or another GM car I would definitely double check which terminals do what on the new fuel pump and which wires on the vehicle should go to those terminals before plugging this connector in! On my particular vehicle, the color coding on this harness connector was not the same as it was on my car's harness! Hope that helps!
