Default Replacing 86 ECM

Hey guys, having a few issues with my Vette, which I believe is stemming from the ECM. I believe I read in the manual one time that if you change the ECM, you have to take some component out of the old ECM to put in the new one? Does anyone know if that's correct, and if so, what part it is? Thank you!
