4 Plug Chrysler PCM
These Engine Computers typically bear a Daimler Chrysler Part Number on a larger sticker. This number comes after P/N, and in this instance, it reads as “05150301AE.” It represents the Hardware Part Number that identifies a group of these computer units. However, this is NOT the number you should search for. While it might technically fit your vehicle, it’s unlikely to assist in getting your vehicle back up and running. The S/N (Serial Numbers) displayed are also of no use, as they are solely for the manufacturer’s internal records.
The number you truly seek is the Software Part Number, which supersedes the original Hardware Part Number after the update. This number can be found on a separate sticker, distinct from the Daimler Chrysler P/N. Look for a sticker marked with “Authorized Software Update.” That is the tag you need. Disregard the “Module S/N” and “SEQUENCE#” information. Usually, the Part Number can be found following the “Module P/N” below the “Authorized Software Update” line. The PN may even be shown twice to ensure you have it correctly.
Located in the upper right corner, as depicted in the image, you’ll notice the Part Number once again, but in a larger font size. For our PCM model, the part number is “68054123AC”. However, the process of finding the right part number for a 2 Plug Chrysler PCM is much simpler.

At first glance, you’ll likely spot a series of numbers etched onto the PCM case, as shown below, and may assume that one of these numbers is what you’re looking for. However, they are all incorrect.
The correct number can be found on the smaller side of the engine computer. You’ll notice a few labeled numbers in that area. Disregard the Module S/N as usual. Directly above it, you’ll find the Chrysler P/N. The number that follows is the one you need to search for.
To the right of the original number, you’ll find a repetition with varying font sizes for the first and second half of the part number. In this particular case, our part number is “05293014AC”
It’s worth noting that these PCMs may sometimes have authorized software updates, indicated by additional stickers placed on top of the original Part Number sticker.
