    411 swap 1996 silverado

    I know I need a computer from a 01/02 express van with the L31 engine, plus 2 connectors for the 411 pcm. Does anyone have or know where to get the pinout spreadsheet?

    Recently acquired a 1996 Chevy Silverado and the speedometer is 15-25 off at various speeds due to a gear swap. And want to swap a 411 pcm in it to see if I can correct that as well as tune it

    You can go to LT1Swap.com and download the stock pinouts, and make a spreadsheet pretty quickly.

    Or, you can contact Jeff Jones on this forum. He goes by the name of Lextech. Just PM him and ask him for the spreadsheet that he developed.
