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.

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.

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 a new signal is applied to start wire after run-time expiration. The system will continue running and re-starting if the system receives new commands to start.

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.
