    Quality Harness

    Posted by Colton on Dec 15th 2018

    Truck was throwing an intermittent p1316 code. Upon inspection, UVCH was loose and kept losing connection. Replaced them with these new OEM UVCH and new valve cover gaskets and the problem was fixed! The new harness seems to plug in much tighter and will hopefully eliminate this problem for the future.

    Superior Part

    Posted by Sous on Nov 26th 2018

    Replaced both harnesses when GP's tested bad during a SXE turbo install. Previous owner had installed a Dorman UVCH on the driver side of the engine. Side by side comparison between the Dorman and Ford, there was no contest or question that the Ford was far superior.

    Quality product and great support from RiffRaff.

    Ford motorcraft parts at the best pricing I could find. They shipped within 2 hours of when I ordered. Can't ask for more.

    Quality part, fast shipping

    Posted by Unknown on Apr 7th 2018

    Had a SES light with two open injector circuits resulting in a "dead miss" on a couple of cylinders all of a sudden. Ordered harnesses for both sides and they arrived the next day! Replaced the parts which fixed the SES and engine miss but also fixed some issues I had had with romping on cold start and after towing (hot). Engine is smooth, smooth again!

    Riffraff ships fast and always helps me in a bind. This harness fixed my high low code coming up from my old harness going out. Great quality and price.

    Quality Almost There

    Installed these with new glow plugs and one of the connectors was loose. Only time will tell if this will be an issue.
