    LS 5.3 Drive By Wire ~ Stand Alone Wiring Harness (TAC Module) Question

    I'm simplifying a factory LS 5.3 Drive by Wire harness for stand alone service. The question I have is how to wire the Throttle Actuator Control (TAC) Module Stop Lamp In (STP LP IN) wire Light Blue (LT BLU) pin 6.

    From the schematic I have (posted pics below), I'm thinking Ignition Power (On - Start 12 VDC) is sent to the TAC Module when the brake pedal is depressed?

    Are the Mitchel's Manual Schematic I posted pics of correct?

    Thanks in advance,

    dave w
