How to reach the ECM and bypass the GM Passkey 2 System
This instructions are for Installing the NEWROCKIES PRO Module to bypass the PassKEY 2 Security System at the ECM. If you would like to install it at the BCM, please refer to: Installation at BCM.
If you don’t have the BCM (i.e. project/race car) you can install the PRO bypass at the PCM. Locate the Powertrain Control Module (PCM) as in the diagrams below and disconnect connector C1 (Blue). This is the connector where all the connections will be made.
