7.3L Powerstroke Engine Harness – 1999–2001 Ford F-Series

Automatic Transmission | California Emissions | Built After 10/25/1999
Part Number: YC3Z-12B637-BA

Electrical issues on a late ’99–2001 7.3L can quickly turn into a nightmare—injector drop-out, rough running, intermittent no-starts, or random sensor faults. In many cases, the root cause is a failing engine harness.

This OEM-style Engine Harness (YC3Z-12B637-BA) is designed specifically for California emissions trucks with automatic transmissions built after 10/25/1999, ensuring correct connections, proper routing, and reliable communication between your injectors, sensors, and PCM.

🛠️ Why Replace Your Engine Harness?

Replacing the harness restores proper signal integrity across your entire engine system, improving reliability and drivability.

Japanese-Style 4-Panel Screen Room Divider: Beautiful, But...
Color: Black, Color: Black
I really like this product, and would gladly recommend it. But there are a few things you want to know before buy: Likes 👍👍👍 - Looks great! See photos I shared. - Works as advertised: divides your space and provides privacy, with elegance and style. - Lightweight: It is super light and easy to move around. Dislikes 👎👎👎 - Flimsy: according to the dictionary, that means "light and easily damaged" 🧐 - Pricey: Anything is worth what you're willing to pay for it! But I think this should be $75 tops! - Shaky: You need to position it just right, or it could tip over really easily. I had to reposition mine because it almost got blown by a floor fan! True story 😅 - Print is on one side only which will bother some of you. I'm a recovering OCD 😂 My Verdict 🧐 - Despite its shortcomings, I like this thing, and I would buy it again! 😅 It has character and really adds to your space. So, now that you know what you're getting, you can make up your own mind! I've already bought mine 😉 Happy shopping 😊 Hope my review has helped you make a more informed buying decision 👍😊👋

Cute backdrop for videos and room separation
Color: Black
Bought this because sometimes you need emotional boundaries AND physical ones. Surprisingly sturdy, looks nice on camera, and makes a room feel more peaceful instantly. Side note I have 2 cats and 2 large dogs and it has took a couple of beatings but did not damage at all!

Transforming Space: A Tale of Two Stunning Room Dividers
Color: Black, Color: Black
The four-panel screen room divider is absolutely stunning! Unfortunately, the first one the FedEx driver delivered ended up at the wrong address. After notifying Amazon, they promptly sent me a “replacement” room divider through UPS, which arrived right on schedule. Now, I find myself with two beautiful dividers! They both enhance the aesthetic of my home. I informed Amazon that my first room divider magically appeared today in my building’s lobby. I’ve placed one of the new screen dividers in front of an old one, and the modern Roundhill divider really makes my older piece look outdated! The Roundhill screen divider is sleek, bold, and refreshing—I’m in love with it. The second divider serves a practical purpose by hiding my bulky grocery cart, fan, and vacuum cleaner. These items used to clutter my living room closet, making it difficult to access due to the abundance of coats I had stuffed in there. Now, all those items are neatly tucked away behind the elegant Roundhill four-panel screen divider, bringing a sense of order to my space. Thanks, Amazon! ♥️ Thanks, Roundhill! ♥️

Beautiful, Sturdy, Well Made, good Value for the money
Color: Black
I don’t know what the bad reviews are about. This is a beautiful, well made 4 panel screen. The screen print appears to be a standard print that is likely the same on every screen they produce (not hand painted by two different people). It is beautiful. Everything about it, including the colors and the screen print image on rice paper, is more lovely than the photos. The wooden frame (black) is solid and sturdy. The hinges are stable and well positioned. When people say lightweight it sounds misleading. It is lightweight enough to easily maneuver but this four panel screen is sturdy and stable. It is slim and tall so someone could conceivably bump into it and jostle it. But no more so than any number of other items in one’s home. I highly recommend this beautiful, lovely, fine piece of home decor. I purchased this as a divider between my work station (office) and my living room. Also, even though there was a slight dent in the package when it was delivered, it wasn’t a deep enough gash to damage the screen. When I pulled the screen from the box my first thought was just how study it is. So very pleased with this purchase.
