NOTE A: THE CUSTOMER CONNECTOR BRACKET GROUND STUD MUST HAVE A DIRECT WIRE
CONNECTION TO BATTERY (-).
NOTE B: REFER TO THE INSTALLATION GUIDE FOR ADDITIONAL INSTALLATION DETAILS
NOTE C: MAXIMUM LENGTH OF DATA BUS (TERMINATION RESISTOR TO
TERMINATION RESISTOR) IS 40 METERS
NOTE D: PLACE APPROPRIATE CIRCUIT PROTECTION
NOTE E: USE RECOMMENDED CABLE OR EQUIVALENT PER SAE J1939 SPECIFICATIONS
FOR ALL J1939 DATA LINK CONNECTIONS
NOTE K: WHEN THE SHUTDOWN SWITCH IS CONNECTED TO BATTERY (-) THE ECM DISABLES
THE FUEL INJECTION SIGNAL. THIS ACTION CAUSES THE ENGINE TO SHUTDOWN
WHILE LEAVING THE ECM POWERED TO MONITOR ENGINE DIAGNOSTICS
NOTE X: USE KIT 156-7106 WHEN REPLACING CONNECTOR 153-9693.
REFER TO REHS1809 FOR REPAIR AND INSTALLATION DETAILS.
NOTE V: ARC SUPPRESSION DIODES ARE REQUIRED
ON RELAY COILS AND SOLENOID COILS.
NOTE W: WIRING FOR DESIRED SPEED CONTROL DETERMINED BY APPLICATION.
FOR DESIRED SPEED CONTROL OPTIONS, REFER TO THE ELECTRONIC
INSTALLATION GUIDE.
NO ADDITIONAL CONNECTIONS ARE ALLOWED TO ANY WIRES
WITHOUT CATERPILLAR ENGINEERING APPROVAL
UNLESS OTHERWISE SPECIFIED:
ALL WIRES TO BE 16 AWG OR LARGER SAE J1128 TYPE SXL OR
EQUIVALENT. FOR TWISTED PAIR SPECIFICATION SEE SAE J1708
