Function of this part

The engine control module (ECM) is the electronic brain of the engine. It reads information from sensors and commands fuel delivery, timing, and other actuators to keep the engine running properly.

Why this part matters

Without a functioning ECM, the engine will not start or will run poorly. A correct, working ECM is essential for performance, diagnostics, emissions control, and protecting the engine from damage.

About the brand

Eaton components are commonly used in commercial truck and equipment applications where dependable performance and proper fit are important.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

Looks great.
Love the look. Took a bit to put it together. The only negative was putting on the back with the tack nails. There was no way to see if you were hitting the board so I missed it about 1/3 of the time. Might be better to use wood glue and forget using the nails.

Perfect for a small bathroom
Nice cabinet for the bathroom. I have a 120-year-old house with small bathrooms; this doubled the cabinet space; the white keeps the room visually larger. I'd like to add the instructions are awesome: no verbiage just step by step diagrams. Each hole drilled and ready, as well as pilot hole where the screws will be received. Each piece labeled. The instructions have in the listings the count of pieces with a notation of extra screws, so you don't think you "screwed up" when you're done. One note: as the shelves are part of the construction, they are not adjustable, in my case not a big deal.

Decent product, you get what you pay for
Easy to put together and good price, fit the space we had perfectly. Cheap material, but you shouldn't be surprised considering the price. I saw another review commenting on the difficulty lining up the nails for the back. Wish I would have read it before the assembly as the nails popped through the front side and I had to knock them back and repaint the spots. The directions don't state which size drill bit to use for the wall anchors, but 5/16" worked well. Overall, not great but not terrible either.
