Upper Sensor Branch Wiring Diagram

zetec - 73

I bundled the wiring for the sensors that were to be above or around the intake manifold assembly into a grouping I called the Upper Sensor Branch. Those lower down would be called, yes, the Lower Sensor Branch. The Upper Sensor Branch dealt with the Fuel Pressure Sensor, the Throttle Position Sensor, the Air Temperature Sensor, the Cam Sensor, and MAP Sensor.  Wire M16 would be spliced to provide 5 volt power to any sensor that might need it. Wire M26 would be spliced to provide grounding for the sensors. The wiring sequence would proceed from the ECU to the front of the motor and then along to each sensor until reaching the back of the motor.
