GM GEN V GDI Sub harness for Late LTx Engines. The fuel pressure sensor easily identifies these engines, Late engines use a 3-pin fuel pressure sensor. GM uses two different fuel pressure sensors with the Gen V LTx engines. Depending on which one your engine has, will determine which harness is required. The Sensor is mounted to the back of the driver-side fuel rail.
