I have a 1996 GMC w / 4L60E looking to re-pin to 411 PCM. The 411 PCM is from a 2001 Chevrolet Astro Van with 4.3L and 4L60E. What steps will need to do when I start the re-programing process? The 411 PCM has an OS with 12202088, the credits for the 411 PCM has been purchased and benched tuned to disable the VATS.
Thanks for your help.
