DESCRIPTION AND OPERATION
36-pin red connector (C507):
This connector is used primarily for sensor inputs to the ECM.
NOTE: Voltages and other measurements given are approximations only. Actual values will
depend on particular specification and will be affected by accuracy and calibration of the
measurement tool used and impedances caused by harness wiring etc.
