Well I'm finally ready to do this upgrade and have all the plans and materials (I think). I was held up for a long time by the 4L80e in my '91 Burb since I thought it used the Bosch style force motor with required cleaning cycle. Found the good news this week that it's actually the next gen Holley force motor in there so it seems like I should be OK to move forward with the swap. (It's actually a '93 Goodwrench replacement tranny) I have PCM, red/blue connectors, and BIN that should be a good starter for a vortec 383. Time to start the re-pinning project. I used the '91 and '94 G30 with 4L80e pinout diagrams in the two attached zip files to create the attached Excel pin mapping chart. If you go into the Excel it may be confusing at first glance. The 7427 pin addresses are in the middle columns and then you work outward from there to description, origin, wire color, and finally the 7060 addresses in the outer columns. I've double and triple checked what I can and am 99% sure I have everything correct on the 7427 side since there are multiple sources to use for validation. The 7060 pinout is harder to verify with fewer sources available. My plan is to verify wire color as I go along and if there's any disagreement I will have to trace it out and make sure origin is what I think it is.

Not asking anyone to do a detailed check, but if there is something glaring that I'm doing wrong ,or something missing, please point it out. And who knows, maybe this will help someone if there's anyone out there that needs to upgrade from a '91-'93 '7060 PCM.

Many thanks to Dave W for the help, pinout files, BIN, selling me the PCM and connectors, etc.
