  1. Chevy Impala 8th Gen Discussion
    Does anyone know the ECM pinout of the E38 ECM for these cars, or if they are the same for everyone. I found this Vortec 5.3l pinout but I am unsure if they are the same and don't wanna ruin anything by removing the wrong pin or adding a pin somewhere that it can't be used.
