Step 5 – Connecting Cable (continued #3)
Optional Outputs
S4 provides two output connections that may be used if
desired by the Owner:
Out #1 for engine starter disable / enable relay
Out #2 for brief pulse operation that maybe used for door
unlock, door lock, flash headlights, sound horn, etc.
Out #1 12v Power (pink wire with fuse) – Connect the S4
pink wire to same the same vehicle wire [HOT AT ALL
TIMES] that was used for the S4 red wire. The included
relay provides two orange wires for the normally closed
(NC) contacts. Using the shop manual diagram locate the
vehicle wire from the ignition switch that feeds the starter
solenoid when the key is turned to start. Cut that wire and
connect the two orange wires so that starter power must go
through the relay contacts. Under normal conditions, the
starter will operate normally. If the Owner sends a secure
SMS to the S4, the S4 Out #1 energizes the relay, which
disables the starter. Review Step 6 and Step 7.
Out #2 Pulse (blue wire) – This S4 output is normally at
12v and goes to zero volts for 1 second if the Owner sends
a secure SMS to the S4. Maximum sink current is 250 mA.
Depending on the function desired by the Owner, the
Installer will decide if they need to add a relay or can use
this digital signal from the blue wire to trigger a logic
function in the appropriate vehicle module. In some cases,
the Installer may use a data transponder module to connect
to the vehicle control buss. Review Step 6 and Step 7.
