Before beginning installation, ensure the vehicle's battery is disconnected to prevent electrical shorts. This harness is designed for a straightforward connection, but basic knowledge of car audio wiring is recommended.

4.1. וויירינג קאַנעקשאַנז

Match the color-coded wires of the Scosche CR04B harness to the corresponding wires on your aftermarket stereo's wiring harness. Refer to the EIA Wire Color Code Chart below and your aftermarket stereo's owner's manual for specific wiring details.

• Connect the constant 12V power wire (typically yellow) from the aftermarket stereo to the yellow wire on the CR04B harness.
• Connect the ground wire (typically black) from the aftermarket stereo to the black wire on the CR04B harness.
• Connect the speaker wires (e.g., white/white-black for left front, gray/gray-black for right front, green/green-black for left rear, purple/purple-black for right rear) from the aftermarket stereo to the corresponding wires on the CR04B harness.
• Switched 12V Accessory Power: Many Chrysler, Dodge, and Jeep vehicles from this era do not provide a switched 12V accessory wire in the factory radio harness. The CR04B includes a separate red fused lead for this purpose. You will need to connect this red fused lead to a reliable switched 12V power source in your vehicle (e.g., the cigarette lighter power wire).
• Connect any other wires such as amplifier turn-on (blue/white), antenna power (blue), or illumination wires (orange, orange/white) as per your aftermarket stereo's instructions and the EIA chart.
