Every car is a little different, but the basic process is similar:

Remove trim panels: Use your panel tools to carefully pop off any plastic trim around the radio.
Unscrew mounting bolts: Most radios are held by 2-4 screws.
Slide out the factory stereo: Gently pull it forward. Don’t yank—wires are still attached.
Disconnect wiring harness and antenna: Squeeze the tabs and unplug everything.

Extra tip: Take a photo of the wiring before disconnecting. This can help if you need to double-check connections later.

Step 5: Connect The Wiring Harness

This is often the most confusing part for beginners, but it’s essential for a safe and reliable installation.

Wiring Color Codes

Most wiring harnesses use standard colors:

Yellow: 12V constant (battery)
Red: 12V switched (ignition)
Black: Ground
Blue: Power antenna/amp turn-on
Orange: Illumination/dimmer
White/White-black: Front left speaker (+/-)
Gray/Gray-black: Front right speaker (+/-)
Green/Green-black: Rear left speaker (+/-)
Purple/Purple-black: Rear right speaker (+/-)

Always verify with your car’s wiring diagram and the stereo manual.

Steps To Connect

Match wires by color from the stereo harness to the adapter harness.
Strip 1/4 inch of insulation from each wire.
Twist and crimp or solder each pair of wires.
Insulate each connection with tape or heat shrink tubing.
Double-check all connections before plugging in.

Pro insight: Use a multimeter to verify the ground and power wires before connecting. Some cars have non-standard color codes.

Step 6: Prepare The Dash Kit And Mounting Brackets

Most aftermarket stereos need a dash kit to fit snugly in your car. Here’s how to set it up:
