    1998 S10 BCM work with 411 PCM from 2002 Silverado ?

    For my 1998 Snoma/S10 swap, I bought a 4.8/4L65E which came out of a 2002 Tahoe. I pulled a 411 PCM from a 2002 Silverado.

    For now, I am not planning to make any mods and will be installing the 4.8/4L65E bone stock. Later, I will install a bigger cam and have the PCM re-tuned, Passlock removed and 2nd O2 sensor removed.

    Since my 1998 Sonoma/S10 has Passlock & BCM and both are already synced, will it send correct signal to the 2002 Silverado 411 PCM to fire the motor without re-flashing the PCM?

    Would I need 2002 Silverado/Tahoe 411 PCM and matching BCM and jus re-teach the Passlock?

    My truck does not have power windows or locks. Just ABS and Cruise Control. Not sure how the Silverado PCM will work.

    Thanks
