    Default Need help with ECM installation 2002 Silverado

    I got a used ECM that has been flashed to work in my truck. I researched the guy who did it and he has many happy customers so I feel pretty good about the quality of the ECM. I know where the ECM is located and it looks pretty easy to remove old and install new; remove battery, remove battery tray, disconnect 2 wire headers, unbolt ECM and go in reverse for reinstallation.

    Are there any tricks or cautions I need to be aware of? I don't wnat to screw up my new ECM by being too anxious.

    Thanks in advance for your help.
