Cummins QSB6.7/QSL9/QSX11.9/QSX15 Tier 4 Interim Wiring Diagram Details Detail 'A' - Intake Air Heaters - 12 Volt OEM Side 2 AWG (-) (+) Intake Air Heater Output OEM 60-Pin Connector ECM Return 2 AWG 250 A 12V System Cummins Supplied Air Heater + 2 AWG + Detail 'B' - Intake Air Heaters - 24 Volt OEM Side 6 AWG (+) (-) Intake Air Heater Output OEM 60-Pin Connector ECM Return 150 24V System A Cummins Supplied Air Heater 6 AWG 6 AWG + OEM responsibility (assume 12V system is used): 1. Procure and install Heavy solenoid switch ("off engine" mount for environment durability) with following charateristics:

- 12 VDC SPST (Ametek Prestolite switch SBJ-4201 works) - 200 amps steady state coninuous current rating - Break current 200 amps - 600 Amp In rush capability - Water resistant 2. Provide wiring capable of 200 continous amps from battery positive terminal to Heavy Duty solenoid battery (+) terminal and from heavy duty solenoid output to grid heater element input 3. Provide solenoid control wiring from the ECM OEM connector to the "off engine" mounted heavy solenoid switch. 4. Note that grid heater current is returned to Battery negative via engine block ground. OEM is responsible for installation of engine block ground in vehicle installations. Diagram Page 4 of 9 Revision 9.0 APR 2014
