I swap a lot used ECM's not new ones on older Chrysler's and never need the PIN. Is a used computer or new?
Powertrain Control Module Initialization:
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the PCM using an after-market scan tool with a "VIN Write Function".
This is an example without disconnecting anything except the battery once to swap the PCM. The vehicle have transponder Key: http://tinyurl.com/hme3fa2
