Example of connectorConnectors are illustrated frequently in order to show pin locations that are used in the tests.Note: This module uses J1:25 in order to refer to a pin location. This means that the pin location that is being referred to is ECM connector J1 and the pin that is being referred to is pin 25. Other publications may refer to this pin location as J1-25 or J1 pin 25.
