Good quality.
Fit great on my 2004 F250. Only thing I struggled with was working it to all my injectors. Since it’s been sitting in the bag a while, it’s formed into a circle in the wrong direction and will fight you the entire install. After you get it on though, it’s fine. Everything was good quality. It was just strange having the brand new harness and the old oil soaked, tape sticky harness to compare to. I’m no longer having to worry about broken FICM clips and thats enough for me. Happy with it.

Bad Connections Immediately!
Installed this wiring harness to replace the OEM which was damaged during an injector replacement. Immediately had codes at multiple injectors. Doesn’t look like pins were seated correctly and I’m not fixing pins on a brand new product. Returned to Amazon! Bought a different harness, and found the same issues, but on different cylinders. Just had brand new injectors installed, so I know these codes are at the harness. Looks like all of these cheap harnesses have issues because of poor quality control. Some people get one that fits perfect right out of the box, while others of us find bad or poorly seated pins, or even crossed pins. It’s like playing the lottery, but it takes two hours of your life every time you don’t get a working part.

Not perfect. But it’s a good product and a great affordable replacement
I bought this to replace my factory harness that had a broken FICM connector. This harness seems to be good quality. FICM connectors fit better than my factory connectors, But the harness on the front of the driver side could be made a little longer. However, it was not an issue, I had the swap done in less than 2 hours and I only used like 4 different sockets.

Could be a little better.
OK, for the price, this is nice. I have a couple of issues though. 1) the mounting tabs are not lined up exactly right, some are unusable. 2) the wires at the fuel Injector plugs are uncovered. It wouldn't be hard to extend the tape another 1 1/2 inches. The looming and tape was otherwise solid feeling and the harness all together seems decent. When I have time, I'll fix the uncovered wires.

Meter connections
Looked good. Installation ok problem was cured on #3 . After install 3hr later new problem 5 injectors and many $$ over 3000 . Found out harness had a missing pin @&#'. Had to buy a factory harness after 20 days of waiting for vehicle to get done . Quality Control is not good at this company on building the item ! Would have been better item of this harness. Hate to have to spend time checking and money for to check out the companies item. BEWARE!!

Really good alternative to the OEM harness but at a good price, just pay attention to the routing of the harness so not to cause future problems.
