Programming

For Plug and Play you must do the following steps:

Step 1: Match your part number per above fitment/interchange notes

Step 2: Program PCM to your VIN. You will need your local mechanic, dealer or properly equipped locksmith to program your VIN into the PCM and apply any necessary updates. Without doing this you will get a "no start" condition.
