Hi, my question is how hard is an ecu to install? Is there any programming to do to the unit or can I just remove and replace it and plug it back in?

For location, see image. R&R is removal of a strap and/or bolts securing the ECM in place and disconnecting the main harness. ECM will need to relearn. It may take as much as 30 minutes of driving.
