APPEnDIx I. WIRInG DIAGRAMS
The SST-4 can be wired in various ways for a variety of engine control applications. This section
includes wiring diagram for three common configurations:
Aux E-Power Battery. Emergency Power is provided from an Auxiliary Battery.
Programming state would include “C4”.
No Aux E-Power Battery. Emergency Power is provided from normal battery (there is no
Auxiliary Battery) and E-power control is from Start/Stop or Throttle signals. Programming
state would include “C1” or “C2”.
No Aux E-Power Battery, simplified. Fully ignition supplied. Emergency Power is provided
from normal battery (there is no Auxiliary Battery) and E-power control is from Start/Stop
or Throttle signals. Programming state would include “C1” or “C2”.

The Auxiliary (AUX), Throttle (TH), and Start/Stop (SS) are input triggers that are provided by
supplying either a positive signal (+12V) or ground signal.
Emergency Power operation: If using a separate E-Power Battery, the circuit breaker for the AUX
relay on the SST-4 must be connected between the J6 and J5 female push-on connectors. If a
separate E-Power battery is NOT being used, the circuit breaker must be connected between the J6
and J7 connectors. See Figure 2 for connection locations.
