The ECM & added pin wiring no problem. You will need a chip from an auto trans version with the 700R4 to work though. There are T-400 versions out there too that will be different programming so it needs to be a 700R4/4L60 version to work right and have TCC functional. Look for a half ton truck or Suburban and any Blazer as a donor.
