source (See Diagram 1 of
Figure 98: Installing the ECU Alarm Cable—Left Exit Option, on page 130 or Figure
99: Installing the ECU Alarm Cable—Right Exit Option, on page 130 ). The details of the alarm connector
pins are listed in Table 5: SCSI Alarm Cable (15454-M-ALMCBL) and SCSI Alarm Patch Cable

These alarms are generic signals that the operator assigns to a definite wire (color) and name through
the Craft Terminal. Note
Step 2 Tighten the screws of the SCSI connector to a torque value of 4 in-lb (0.45 N-m) using #2 Philips Dynamometric
screwdriver. See Diagram 2 of

Figure 99: Installing the ECU Alarm Cable—Right Exit Option, on page 130 .
Step 3 Bend the cable at an angle of 90° to exit from the left side (see Diagram 3 of Figure 98: Installing the ECU
Alarm Cable—Left Exit Option, on page 130 ) or to exit from the right side (see Diagram 3 of Figure 99:
Installing the ECU Alarm Cable—Right Exit Option, on page 130 ).
