PCM LOCATION

Your current PCM Calibration ID# is needed for ordering your new Modified PCM.

It is always a good idea to consult your vehicle’s owner’s manual to find the exact location of your vehicle’s PCM, but typically they are found in the engine compartment, under the passenger floorboard, under the seats, or behind the kick panels.

Chrysler 300 - On the drivers side, under the hood, behind where you fill washer fluid, but in front of the Power Distribution Center. The TCM is the small box and the PCM is the larger one.
