The 1996-97 PCM (Powertrain Control Module = Fuel Injection Computer) on your 4.3L, 5.0L or 5.7L Engine has a total of 4 connectors. NOTE: For other PCM pin-out charts, take a look at the following: 1993 PCM Pin Out Chart (GM 4.3L, 5.0L, 5.7L GAS w/ 4L60-E)., Most modules will draw under half an amp of current at 12v with very few exceptions (like E86 Duramax ECMs and T43 TCMs). Most tuning tools draw close to 0.1 amps of current. If you're flashing a CAN TCM, BCM, etc you generally either need a ECM on the bench with it or need to add CAN termination. You can do this with a 120 ohm resistor between ...
