As always OEM, quick delivery and best price

I gave Riffraff my VIN and they sent the exact fit wiring harness for the engine. Every length and connection was perfect. I did injectors, turbo rebuild, other odds and ends and she fired up the first crank! No issues with the wiring harness.

Genuine Ford part. I was thrilled that Riffraff had this harness, as they have been discontinued by ford. Works great, thanks Riffraff!

Good quality and fit! Replaced it as a preventative maintenance item, with no issues or run-ability problems. But very happy with how much smoother and responsive the engine is running, must have had issues I never new I had. Made the price well worth it!

Great OEM harness at an amazing price! Super easy ordering once I called in my vin number!

I have had my engine replaced twice with Reman's the engine harness was showing signs of stress, broken insulation, exposed wire, and eventually threw several engine codes, RIFF RAFF has OEM products that are always recommended to the 7.3 community, Replacing the harness was somewhat difficult, as the orginial had taken the paths roughed during the MFG build out, there was some stress built into the new harness that required out of the box thinking to take this stress out of the fuel injector and glow plug harness connectors, the connector wanted to pull or lift from sitting flush and well connected to the receiving 1/2 of the connector, created a work around by tugging the stress towards the fire wall, by a large hose clamp fed through a section of water hose to protect surrounding components, the base support to the clamp was looping around the intake boot, so far it is performing well, a work around that is out of the box thinking, and may help others correcting this problem. Good Luck, I am a repeat customer to Riff Raff, I have a very high opinion of Clay, as he has taken the time required to help me work through several problems, fuel line leaks, upgrades to the fuel system, High pressure oil sys. I am very grateful, and have a very high regard for Clay and his generous help, I am a customer for life, Riff Raff is my go to for all 7.3 needs
