Wiring the Kenwood KDC-248U

Wiring the Kenwood KDC-248U is a straightforward process that can be completed by anyone who has basic knowledge of car electrical systems. Here are the steps to follow:

Step 1: Prepare the Wiring Harness

The first step is to prepare the wiring harness for connection to the car’s electrical system. This involves stripping the insulation from the wires and twisting them together with the wires from the car’s electrical system. Use wire connectors to secure the connections.

Step 2: Connect the Ground Wire

The ground wire (pin 5) should be connected to a metal part of the car’s chassis. This wire provides a path for the current to flow back to the battery. It is important to ensure that the ground wire is securely connected to the chassis to prevent interference or noise in the audio system.

Step 3: Connect the Accessory Wire

The accessory wire (pin 6) should be connected to a source of 12V power that is only active when the car’s ignition is turned on. This wire provides power to the stereo system when the car is running but not necessarily when the car is turned off.

Step 4: Connect the Power Wire

The power wire (pin 7) should be connected to a source of 12V power that is always active, regardless of whether the car’s ignition is turned on or off. This wire provides power to the stereo system even when the car is turned off.

Step 5: Connect the Illumination Wire

The illumination wire (pin 8) should be connected to the car’s instrument panel lighting circuit. This wire provides power to the stereo system’s backlighting and is activated when the car’s headlights are turned on.
