Review on TIKSCIENCE LS Gen 3 ECM Engine Programming Control Module Reader Diagnostic PCM Bench Harness with Power Supply for GM Chevy, Works with OBD2 Port, Blue/Red & Blue/Green Models 1999-2007, 18 Gauge, 12 Volt by Skyy Strickland

The ground wire was connected to the sensor ground (pin 60) and not one of the correct PCM grounds. They are most likely wired together in the PCM, so the controller will probably still get power, but may not be providing a reliable power supply. The wiring at the wall plug is very thin and has no strain relief, so it can be damaged if you're not careful. product care. The OBD2 connector seems to be of good quality, no problems here. The final comment concerns the connector itself. The blue connector protectors fit rather loosely against the white base of the connector, as if the connector were an ill-fitting copy. I haven't looked at many GM PCM connectors so I'm not sure if this is common or not. All in all, I expect this product to work, but it doesn't follow best practices and is far from professional.
