This harness and computer are for the drive by wire LS1 variants ONLY.
Vehicles using these PCMs included the Corvette, Camaro, Firebird, and full-size trucks. The full-size trucks were available with the 4.8L, 5.3L, and 6.0L engines. The only GM calibrations used with these PCMs were for Gen III engines, which were all equipped with a 24x crank reluctor. The Corvette continued to use an electronic throttle body, the Camaro and Firebird used a cable throttle body, and the trucks were available with either a cable or an electronic throttle body. The electronic throttle systems required a throttle actuator control (TAC) module, a small black module that communicates with the PCM to control the throttle body and cruise control system. The electronic throttle body and TAC module was different between Corvette and trucks. [TAC module is not included]
