Hey everyone long time...Im currently working on a 93 Silverado 1500 with a blown transmission I just got

I think I read the computers are interchangeable and would like to use the 7427..

What years of 4l60e can the 427 can operate?
I have a 97 or 99 I could buy as replacements here and was just wondering If I'd be able to use the 427 to control them, or am i stuck from 93, 94, and 95 years?

IF I can use a 97, do I need to cut a length of harness from a junkyard to wire up to the 427 pinouts?

Thank you.
