2.3. Wiring Instructions
There are two primary methods for wiring your new car stereo:
- Method 1: Using an Aftermarket Wiring Harness (Highly Recommended)
This method involves connecting the stereo's power cable to an aftermarket wiring harness designed for your specific car model. This simplifies the connection process by matching the stereo's wiring to your vehicle's original adapter.
Video 2.1: Detailed installation guide for the 7-inch Double Din Car Stereo, demonstrating wiring with an aftermarket harness. - Method 2: Direct Connection to Original Wiring Harness
If an aftermarket harness is not available, you can connect the power cable directly to your car's original stereo wiring harness. This requires careful identification of each wire's function using a multimeter. Please prepare a multimeter and insulating tape for this method.
Video 2.2: Installation steps for the 7-Inch Car Stereo, including direct wiring methods and multimeter usage. Steps for Direct Wiring:
- Identify Ground Wire (GND): Set the multimeter to the 0Ω position. Insert the black test lead into the keyhole. Check wires until the multimeter beeps, indicating the ground wire.
- Identify Battery Wire (B+): Set the multimeter to the 20V position. Check wires until the multimeter displays 11V-13V. This is the constant power wire.
- Identify ACC Wire: Turn on the car ignition (ACC position). Check wires until the multimeter displays 11V-13V. This wire provides power when the ignition is on.
- Identify Illumination Wire (ILLUMI): Turn on the car headlights. Check wires until the multimeter displays 9V-14V. When headlights are turned off, the multimeter should show 0V.
- Identify Speaker Wires: Set the multimeter to the 200Ω position. Find pairs of wires that display 2-8Ω. These are your speaker wires. Use the DSP settings on the stereo to confirm which speaker each pair corresponds to.
2.4. Backup Camera Installation
The included backup camera enhances parking safety. Connect the camera's video cable to the RCIN input port on the stereo. The red wire on the video cable needs to be connected to the stereo's REVERSE-IN wire, which should be connected to your vehicle's reversing lights for automatic activation.
