Table 33– Example 9-cylinder Radial Primary SV-EMS-220 25-pin Connector Sensor Map 
* Note that J-type and K-type thermocouples apply to all CHTs or EGTs, respectively. They are 
not repeated in the table for brevity’s sake. 
In Table 32 above, the Primary SV-EMS-220 uses a 100399-002 6-cylinder CHT/EGT harness; 
these are connected to Cylinders 1-6. 
In Table 33 above, the Secondary SV-EMS-220 uses a 100399-001 4-cylinder CHT/EGT harness; 
cables marked Cylinders 1-3 are connected to Cylinders 7-9, respectively. 
To configure dual EMS’ to support additional thermocouples (CHTs / EGTs), go to 
SV-EMS-220, SETUP MENU > EMS SETUP > DUAL EMS SETUP: 
> DUAL ENGINE MODE: NO 
> PRIMARY EMS MODULE: (select a S/N) 
On the SV-EMS-220 selected as primary, all pins on the 37-pin and 25-pin connectors are 
enabled. On the secondary SV-EMS-220, only the thermocouple (CHT/EGT) inputs on the 37-pin 
and the 25-pin connectors are enabled.
