  • 2020 CT4 V JB4 & BMS WMI Install

    I recently splurged on the JB4 and BMS WMI kit for my 2020 Cadillac CT4 V (non BW) and will update this thread with install info/pics when I get to that point.

    After reading through the install instructions for the WMI kit I need clarification on where the FSB blue wire goes. It looks like pin 14 or pin 16 are the options, but it isn't specified for my engine (L3B). Can I get a definitive answer from someone in tech support?

    For WMI support on that you'll want to email me as I'm not sure its enabled in the public firmware. But use spots 16 for the blue FSB, 3 for the orange FSB.
