Programming / PATS Security
For Plug and Play you must do the following three steps:
Step 1: Match your part number per above fitment/interchange notes
Step 2: Program ecu to your VIN. You will need your local mechanic, Dodge dealer or properly equipped locksmith to program your VIN into the ecu. Without doing this you will get a "no start" condition.
