How do you remove the harness cables on a pcm for a 2005 Colorado?

To remove the harness cables from the PCM (Powertrain Control Module) on a 2005 Chevy Colorado, first, disconnect the vehicle's battery to prevent any electrical shorts. Next, locate the PCM, which is typically mounted near the engine compartment. Carefully unclip the harness connectors by pressing down on the release tab and pulling the connector away from the PCM. Ensure you handle the connectors gently to avoid damaging the pins or the wiring.
