INTRODUCTION

ATTENTION:
IF YOU ARE INSTALLING THIS SYSTEM ON A GASOLINE SPRINTER, PLEASE MAKE SURE THAT THE SOFTWARE VERSION IS V5.23 OR ABOVE IF YOU ARE INSTALLING THIS SYSTEM ON A 2023 SPRINTER, PLEASE MAKE SURE THE SOFTWARE VERSION IS V5.25 OR ABOVE
The SKSNG907 is a remote start and alarm kit for the 2019-2023 Mercedes & Freightliner Sprinter (907)
Link to product here.
Out of the box, the remote start will work using the factory key fob (lock- unlock-lock). It will also include
OEM style alarm with no additional hardware. A Compustar DAS sensor can be plugged in to add shock/tilt/vehicle movement protection to the alarm. The alarm will use the factory horn and flash the parking lights. In addition, a full  Compustar or Directed external alarm can be added.
For extended range, the Compustar Drone and Directed Smart Start can be added and will provide 2-way communication (including alarm notifications). All Compustar RF kits are compatible with the system and any Directed RF kit using an XL202 (XL202 not needed if using Directed external alarm).
The remote start & alarm installation for the SKSNG907 or SKSNG907RV is 100% plug & play to the vehicle and requires the following steps:

• T-harness connection at PCM module
• T-harness connection at EIS module
• Key box installation
• Hood pin installation

There is also a kit (SKSNG907RV) that also includes OEM style high idle and an optional external trigger for start / stop. Link to that product here.

  Suggested location is to wiring harness in driver under dash
  Mount key box in secure location. It is recommended to mount the key box further up into dash area for additional key security

• Mount all modules away from any heat sources or moving parts

• Re-assemble vehicle in reverse order of disassembly steps

Step 30 — Install warning sticker

The provided warning sticker must be installed in this location or your SmartKey Starter® warranty will be voided

• Install provided warning sticker on intermediate panel between A pillar and kick panel

Step 31 — OPTIONAL: External device connection

• For Compustar Drone connection, click here
• For Directed Smart Start Connection, click here
• For Compustar RF remote connections, click here
• For Compustar external alarm connection, click here
• For Directed external alarm connection, click here

Step 32 — OPTIONAL: Compustar DAS sensor connection

To install optional Compustar DAS sensor, connect data cable from DAS sensor to red port labeled Sensor on module labeled SmartKey Starter

• Mount sensor and cable securely and not near any moving parts, pedals, or any heat sources.
• Sensor must be mounted to something rigid in order to detect tilt and impact. An optional sensor mounting location is on the plastic dash panel to the left of the climate controls. Click here for picture.
• The DAS sensor settings and sensitivity can be adjusted two ways: on the buttons on the sensor directly, or in the SmartKey Starter® menu. For menu instructions,click here to see Owners Manual and Operating Instructions
• To adjust the sensor using the buttons on the sensor, lock doors with OEM remote and all doors closed to arm alarm.
• Once the alarm is armed, there will be a 30 second window in which the buttons on the DAS sensor can be used to adjust sensitivity.

Step 33 — OPTIONAL: Expansion port connections

The SKSNG907 and SKSNG907RV with software version 5.26 and up include a 6 pin expansion port and pigtail. This is a 6 wire pigtail with a white plug. The gray wire is used for hood pin (required), as covered in step 20. With this port,  you can also add optional expansions:

• Physical valet switch (remote starter on/off). When purple wire is grounded, system is in valet mode (remote starter off)
• External siren. Brown wire provides siren output (+) for use with included alarm
• High idle off input (disables high idle during remote/auto start). Note: only available for SKSNG907RV. When yellow wire is grounded, high idle will be disabled during remote/auto  start.
• Shock/tilt sensor disable. Note: only if Compustar DAS sensor is added. When orange wire is grounded, DAS sensor will be disabled.
• Black wire is used to supply a ground for siren and/or for use with a switch to use any of the above inputs
• The gray wire is the hood pin input. This is not optional and covered in step 20.
• Solder and insulate all connections. Insulate exposed end of any wire on this pigtail that is not used.

Step 34 — OPTIONAL: START/STOP TRIGGER FOR SKSNG907RV

• The SKSNG907RV includes an analog start/stop trigger to operate the remote start from an external trigger. The cable has a white 4 pin plug and, if using external start/stop triggers, will plug into the white or green 4 pin plug  labeled Trigger Input on the module labeled SKSPCM. Refer to this diagram for wiring.

• The trigger has 2 configurations, 1 wire or 2 wire. The 1 wire configuration (default) will start the engine when the start wire is grounded (green). The 2 wire configuration has a separate start wire (green) and stop wire (white). In the  2 wire configuration, a momentary ground on the start/stop wires will execute the command

• The 1 wire configuration is the default setting. To change to the 2 wire configuration, you can use the SmartKey Starter® menu. The trigger configuration is in a hidden menu. For instructions getting into the hidden menu, please  contact Mid City Engineering at 312-421-1114 or sales@midcityengineering.com

• Note: when using this auto start with external 1-wire trigger (latched ground to start and run) the system will re-start if ground is still applied to start wire after run-time expiration.
  The system will continue running and re-starting until external trigger removes ground signal.

• For Sprinters without the volume and mute buttons on the steering wheel, if the SmartKey Starter firmware is below V5.25, you will need to use a USB programming tool to change this setting

• If analog input(s) not being used, the 4 pin white input cable should not be plugged into the SKSPCM module.
  Be sure to insulate all wires not used on the cable.
