You replace the ECM board with a Megasquirt board and a GM adapter board that plugs the GM harness to the MS. I think '88 to '92 will work. I've been parring down a '90 Suburban wire harness today getting ready for a presentation I'm doing at a club meeting Saturday. That takes some time and running fuel lines is some work. You have to have pressure safe lines and a return. Parts source is DIYAutoTune. http://www.diyautotune.com/
