B3500 Van. Your Powertrain Control Module is located on at the center of the firewall in the engine compartment. . Part numbers should be on a label clearly marked.. (example: 56028579AB) This example does not reflect the actual part number of the (PCM) on your vehicle. If there is no label attached, you local dealership can "read" the part number with their diagnostic test equipment.
