Last post 2002 i think, much older now lol, memory not what it used to be. Looking for instructions on how to pull ecm and replace prom with eprom to have chip burned

 

The ecm is directly under the passenger side speaker. You can access it from under the dash. Disconnect you battery first. Remove the ecm mounting bracket held on with two screws to the dash frame. Depress the ecm connectors latch and pull to release the connector. Remove the access cover to the ecm to expose the memcal. If you are using a piggyback adapter remove the blue cover on the memcal.
