Once you get the ECM cover off and get the ECM out of the way you will need to take the gray cover things off the ECM connectors. Once you do that you need to remove the blue caps on the side that plugs into the ECM. After that you will notice numbers on the back of the connector. You take the dsp pins and shove them in the right number whole. Then reasemble. It's way easier when you start doing it.
