About This

• Precise Fit for GM Chevy Models from 1999-2007, Stress-Free Full-Scenario Diagnostics & Bench Testing: Tailor-made for LS Gen 3 series engines, perfectly compatible with ECM (Engine Control Module) and PCM (Powertrain Control Module) for all relevant GM Chevy models from 1999 to 2007. Supports two core working modes: OBD2 port direct connection and bench testing. Easily meets the needs of ECM/PCM data reading, system inspection and fault diagnostics. It is an ideal matching tool for professional maintenance technicians and automotive DIY users, completely avoiding operation freezes and functional failures caused by model incompatibility.
• Integrated 12V Stable Power Supply, Ensuring Safe & Efficient Module Inspection: Built-in high-quality 12V power supply module, no extra external power supply required, plug-and-play design provides continuous and stable voltage output for ECM/PCM diagnostics and bench testing. Adopts triple safety protection: overvoltage, overcurrent, and short circuit protection, effectively preventing module damage and data abnormality caused by voltage fluctuations, and ensuring stable data reading integrity. No worry about power interruption during module inspection, greatly improving work efficiency and reducing maintenance rework costs.
• APPLICATION: This plug-and-play bench-top test harness is designed for Gen 3 LS 4.8L, 5.3L, and 6.0L control systems from 1999 to 2007. Simply connect to a standard wall outlet to supply 12V power for OBDII diagnostics and off-vehicle module inspection. It works with all mainstream diagnostic software, including EFI Live, HP Tuners and Tuner Cats.
• High-Quality Harness Craftsmanship: The harness adopts pure copper core wires, wrapped with high-temperature resistant, stretch-resistant and eco-friendly PVC outer sheath, delivering great corrosion resistance and anti-interference performance, suitable for complex workshop environments. Precise pin definition and tight connector design ensure stable connection without loosening, as well as steady data transmission without delay or packet loss, offering reliable signal support for diagnostic software.
• Compatible with Mainstream Diagnostic Software, Easy To Use: Seamlessly works with mainstream ECM diagnostic software on the market, no extra drivers required, and the unit can be quickly recognized after connection. Simplified wiring design with clear interface marks allows even non-professional users to finish installation and operation easily. Supports full-range ECU data reading, including error code scanning and real-time data stream monitoring, helping users quickly locate engine faults and complete accurate system inspection.
• One-Stop Maintenance Solution, More Cost-Effective Than Separate Accessories: This all-in-one unit integrates five core functions: ECM data reading & diagnostics, PCM system checking, bench harness, 12V power supply, and OBD2 adapter. No need to buy individual parts separately, saving procurement costs and storage space. Widely applied in engine routine maintenance, module matching and system calibration scenarios. Suitable for daily repair and professional module inspection work, providing comprehensive practical support.
