BEFORE BEGINNING: READ THIS INSTRUCTION MANUAL

Disconnect the negative battery terminal to avoid short circuits. Read ALL vehicle manufacturer's warnings regarding airbags and electrical systems. We recommend ONLY a volt/ohm meter when checking/testing vehicle wiring. A test light (grounded probe type) can damage a vehicle's computer and/or electronics systems.

COMPONENT OVERVIEW

WIRE COLOR CODES

White = Left Front Positive (LF+)

Gray = Right Front Positive (RF+)

White/Black = Left Front Negative (LF-)

Gray/Black = Right Front Negative (RF-)

Green = Left Rear Positive (LR+)

Violet = Right Rear Positive (RR+)

Green/Black = Left Rear Negative (LR-)

Violet/Black = Right Rear Negative (RR-)

Black = Chassis Ground Orange = Illumination

Yellow = +12V Constant Power Blue/White = +12 Remote Output

Red = +12V Accessory/R.A.P output (Amp, radio on signal)

Blue = +12V Power Antenna

NAVIGATION CONNECTIONS:

Violet/White = VSS Vehicle speed pulse signal

Red/White = Reverse light trigger (+12V when in reverse gear)

Yellow/Black = Parking brake trigger (-12V when park brake ON)

Orange/White = Auto illumination (Data controlled lighting output on some GM LAN applications with AUTO headlights enabled)

NOTE: The RED Accessory output wire from the S3-1 interface is rated at 10A Max output for most aftermarket head unit demands. We do NOT recommended connecting additional +12V switched accessories to this output source as it may cause damage to the S3-1 module itself. If 10A output is not sufficient, then a relay is needed (Relay not included).

NOTE: Illumination & auto illumination outputs are designed for head unit connections only.

BASIC WIRING INSTRUCTIONS

The following steps are provided as a general guide. For specific information for your vehicle, consult the instructions supplied with your vehicle-specific S3-1 harness (sold separately).

1. Disconnect the negative battery cable from the battery to avoid short circuits.

2. Remove and unplug factory stereo. (If needed, call Scosche Toll-free Tech for assistance with radio removal: [phone] Ext. 3)

3. Match and connect the Power/ground wires from the S3-1 Vehicle specific harness to the wires provided with your stereo. The color codes on the Scosche harness are designed to match most aftermarket stereos.

- Take note that some of the wires for your new stereo come from the S3-1 interface box itself and not the vehicle connectors.

4a. The S3-1 speaker connections are pre-terminated with RCA jacks for installations requiring Line input: Toyota JBL, GM Standard Bose and Ford Premium sound.
4b. If your vehicle does not have a Bose or Premium system, cut off the RCAs and wire the speaker leads directly to the speaker wires from the new stereo.
4c. All FORD harnesses must have RCAs cut on vehicle side of circuit board.
5. Tape any unused wiring to prevent short circuit.
7. Reconnect the negative battery cable**.

** For GM vehicles, alternate power up (initialization steps) are required.

See General Motors specific notes section.

1. As you install your new stereo, place the S3-1 module(s) and harnesses in the rear of the dash cavity behind the stereo.

OPTIONAL: Cable ties or double-sided tape can be used to secure the module, but are not included.

CHRYSLER & TOYOTA INSTALLATION NOTES

CHRYSLER: PREMIUM ALPINE, BOSTON & INFINITY SYSTEMS

These factory amplified sound systems are driven and digitally controlled by a single set of left/right input channels only. The aftermarket radio does not have the ability to control fade or balance adjustments on these types of systems. There is NO front/rear fader control. The balance and fader are set to center by interface control software.

GENERAL MOTORS INSTALLATION NOTES

HOW TO TEST FOR "PREMIUM BOSE" SYSTEMS

There are two types of Bose systems available in some models of GM vehicles. The S3-1 interface is not compatible with the Digital Premium BOSE (y91/z75 systems) To test for digital Bose systems, turn the factory radio volume up and down rapidly. If the sound system reacts immediately then the system is a Standard Bose, not a Premium Bose. If there's a slight delay in the system as you turn it up and down quickly, then this vehicle may have Premium BOSE. Note: you may also check the service parts code sticker usually located in the glove box for "y91" or "z75" equipment codes.

S3-1 GENERAL MOTORS INTEGRATED SAFETY & WARNING CHIMES

When replacing the factory stereo in your GM vehicle, the S3-1 interface will replace portions of your vehicle's audible SAFETY and WARNING CHIME systems. If the stereo is removed without the proper accessory these functions of your vehicle will be LOST including: Your vehicle's ECM (Electronics Control Module) will also store an error code if operated without the factory radio installed and you may experience difficulty in having the vehicle serviced at the dealership. The Scosche S3-1 will send the proper data commands to your vehicle's ECM (Electronics Control Module) to indicate a "healthy" status for diagnostic purposes.

WARNING & SAFETY CHIMES LIST:

• Parking assist
• Seatbelt warning chime
• Lights left on reminder
• Check engine/service indicator
• Turn signal click
• Key left in ignition reminder
• Low fuel

POWER UP (Initialization procedure)

In order to ensure the proper functionality of the S3-1's +12V RED Accessory wire, we recommend that the following procedure be followed; in sequence.

1. Disconnect the Scosche Interface from the vehicle radio harness.
2. Close all doors and hood, Turn off all lights and remove the keys from the ignition.
3. Wait 3 to 4 minutes (without opening a door, turning on a light, inserting keys, etc.).
4. Connect the Scosche Interface to the vehicle's radio harness and start vehicle.
5. Test interface for functionality.
