Installation Notes:

1.Only one of the two provided radio harnesses will be used. Remove the factory installed radio to determine the correct harness for your particular vehicle.

2.Vehicles without a factory amplifier: Connect the aftermarket radio’s front and rear speaker wires to the 22 pin plug.

3.Vehicles with a factory amplifier: The factory amplifier only accepts two audio channels (left and right). The amplifier’s fading is controlled by data communication from the factory radio.

The aftermarket radio does not have the ability to control the amplifier’s fader. Connect the front

outputs of the aftermarket radio to the rear inputs of the 22 pin radio connector. This will

allow navigation voice prompts and Bluetooth calls to be heard. The rear speaker outputs of the aftermarket radio are not used.

4.Vehicles with a manual transmission will not support a reverse trigger output.

5.The accessory output wire is located on the 11 pin CAN INTERFACE harness - connect this wire to the radio’s accessory wire. The accessory wire supplies +12v, 1 amp max when key is in the accessory or ignition position (fig. 1: If more current is needed).

6. 11 pin plug (to CAN INTERFACE):

1. Blue/White - Connect this wire to the radio’s amplifier remote output. Connect this wire with or without OEM amp present!

2. White/Green - SWC output.

3. Green - Connect this wire to the radio’s reverse input wire only.

4. Orange/White - Connect this wire to the radio’s Illumination input wire only.

5. Violet/White - Connect this wire to the radio’s VSS input wire only.

6.Red/White - Connect this wire to the radio’s parking brake input wire only.

Note: Do not connect these wires to any circuit other than the radio’s wire harness.	12v Acc.
