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.

So good
Format: Paperback
RATING : ⭐️⭐️⭐️⭐️⭐️ SPICE: 🔥🔥 Hot damn Hannah did it again .if you want to read more sapphic romance, this one will absolutely blow your mind! Bryce and Daisy were everything I wanted and more! Fake dating will always be the superior trope, but when it’s forced proximity grumpy x sunshine and the grumpy one is secretly head over heels for the sunshine one, well I’m a damn puddle on the floor! I still can’t decide if I loved Bryce or Daisy more, but I do. Know this might just be my favorite book Hannah has ever written. ☀️ Fake Dating ☀️ Grumpy x Sunshine ☀️ Forced Proximity / Roommates ☀️.Tattoo Artist / Teacher ☀️ So much pining I love Bryce so much. She is a total hard shell but she has such a gooey inside and she showed it so well with Daisy. This whole setup was fantastic, Daisy needs a place to stay so Bryce gets volunteered to give up her spare room. Daisy think Bryce doesn’t like her, but then you get to Bryce’s POV and you realize how down bad she has it for Daisy. Then Daisy proposes the fake date and OMG the tension. The longing. The secret tattoos. I loved every bit of these two figuring each other out. Watching Bryce absolutely melt for Daisy was just so so good. This may be a slow burn, but when it burns…. It’s an inferno. And the tattoo parlor scene is imbedded in my brain forever. Just everything about this made me happy and I will forever love Cherry Peak, these characters and this series! Now bring on Darren!

Love them!
Format: Paperback
“Calling Daisy Mitchell mine is a dream that I never planned on coming true but always hoped would.” Gahhh my first FF and I’m hooked! Thank you Hannah! Daisy and Bryce are as opposites as can be, one is pure sunshine and the other is as icy as can be but they couldn’t be more perfect for each other! I love the slow burn with all the sexual tension as they pretend to date while living together. Love the way they take care of each other, the love and admiration so evident in the way they touch and look at each other. Their nicknames for each other is just so cute and perfect! I love these two so much! Such a great addition to the Cherry Peak series! We get more of Johnny, who happens to be Daisy’s twin and I just can’t get enough of him either, he’s just so fun. And of course we get to see more of the rest of gang. Love these found family and I can’t wait for more!

Great resource for comic book writers
Format: Paperback
This book is exactly as advertised: a great collection of comic scripts by some of the best writers in the field. This is important for two reasons: 1) There is no set format for comic scripts, so seeing examples of how other people write theirs is invaluable. 2) It can be hard to find sample comic scripts online, especially by the top names in the field. Here's nine of them in one shot. Reading this book will give you great insight into how comics are made, and also how some of the best creators in the field approach their craft.

Exactly what it says it is on the tin.
Format: Paperback
It's a collection of comic book scripts, written by some of the best in the business. I'd love it if there were more examples of the finished product, and a step-by-step of back-and-forth between writer and the rest of the creative team would be awesome, but if what you really want is examples of the real deal, this is it.
