Electrical issues on a 7.3L Powerstroke can feel impossible to pin down. One day, the truck runs fine, the next, you’re dealing with injector misfires, rough idle, hard starts, or random sensor problems that seem to come and go without warning. On many high-mileage trucks, the factory engine harness becomes brittle over time from heat, vibration, and years of engine bay exposure, creating inconsistent signals throughout the system.

This direct replacement Engine Harness for Ford F-Series 7.3L Powerstroke trucks is designed to restore reliable communication between your injectors, sensors, and PCM with factory-style routing and connections. Replacing a worn or damaged harness helps eliminate intermittent electrical issues while improving drivability, consistency, and overall reliability. Built with durable, high-quality wiring and OEM-style connectors, this plug-and-play harness is made to handle harsh engine bay conditions while keeping installation straightforward for repairs, maintenance, or full engine refresh projects.

IMPORTANT FITMENT NOTE: Designed specifically for 1999-2001 Ford F-Series 7.3L Powerstroke trucks only. Please verify your truck’s model year and engine application before ordering to ensure proper fitment.

Good quality sound deadener at a good price.
Model: NewSLS50_52
Quality sound deadening that adheres to body panels well. You can easily hear the vibration reduction after just the first piece by tapping on the body panel before and after.

Good stuff at a good price
Model: NewSLS50_52
Works well and sticks well. I used a roller and it has been over a year and everything still sticking as good as day i put it everywhere. I didnt use any adhesive but I did wipe everything down with acetone before I applied. Good stuff at a good price

BUY THIS ONE!
Model: NewSLS50_52
This is one of the good ones. There are other brands just as good, and manny brands are worse, but this handles well, rolls down easily, doesn't come off at all easily, and adapts to dips and curves like a champ. Appropriately heavy and dead, I'm happy with the way it smothers panel resonances and even at muffling direct sound, like a big hand over my Uncle Harry's eternally noisy mouth. You can rip the foil but you have to work hard at doing that. Remember to buy a brayer; you can roll overlaps nice and thin. Also remember to pre-wipe the sheet metal with a decent solvent like acetone or Stoddard/Varsol. It should last forever.

Good stuff, but watch the temp
Model: NewSLS50_52
I used this in my single cab pickup truck (89 ford.) It only took half the box (10 sheets or 25 square feet) to do the floors, but I bought the big box because I plan to do the doors, back wall, and maybe the roof as well. One thing I learned is that the temperature matters when you’re doing the installation. It was around 55F when I started in the evening, and when it dipped down into the 40s the sheets would not stick to the metal, and were hard to compress with the roller. That’s why I ended up only doing the floors and not any vertical surfaces; i will have to wait for a nice hot day. The other thing is that the foil layer on top is razor sharp at the edges, definitely wear gloves! I didn’t notice until after but I have little papercuts all over my fingers. Aside from those things, the install was easy and straightforward. The sheets cut easily with scissors, and any goo that ends up on your hands or scissors can be cleaned up with acetone (nail polish remover), or lacquer thinner. I would use this stuff again.
