5C3Z-12B637-BA Engine Wiring Harness for 2005 2006 2007 F250 F350 F450 F550 Ford Super Duty 6.0L Engine Wiring Harness Diesel Engine with Build Date of 11/4/2004 and Later 5C3Z12B637BA

Being made in China I was skeptical but being half price to competitors I figured I’d try. It matched right up, connections are tight and of high quality. Direct oem replacement, no issues whatsoever. 2006 f-350

Some connectors do not lock well. Specifically the temp sensors and PCM connector. Harness was very tight in spots. Above all, wiring colors do not match oem and truck is "no start" after replacing. Wire size for glow plug module considerably smaller than oem.

They sent the right part! it was received in a timely fashion

Plugs were wrong and was wired up incorrectly. Do not waste your money on this harness. It’s nothing but a giant waste of time.

Truck is crank no start after installing do not buy or install get one from pro source diesel

Terrible

Estaba repatando el motor y hoy que la pusimos. No es la misma

Terribly made. Everything was wrapped way too tight, almost impossible to manipulate around to where it needed to be. Had to repin connector ends to make it work in the truck. I would’ve returned it but I needed to get it back running. Spend the money and get one from ford instead. Very dissapointed

Paid ford dealer to install it and find out it's not wired correctly so my timing sensors won't read and truck been a no start ever since. Don't buy this it's more problems than solutions.
