Circuit K6 is spliced and provides 5 Volts to the A/C pressure switch and the map sensor.On automatic transmission vehicles, circuit K22 is spliced and provides an input to the Transmission Control Module (TCM).
Circuit K4 splices to supply ground for the signals from the following:
- Intake air temperature sensor
- Camshaft position sensor
- Manifold absolute pressure sensor
- Ambient temperature sensor
- A/C pressure switch
- Crankshaft position sensor
- Vehicle speed sensor
- Heated oxygen sensors
