Step 1: Disconnect the Negative Battery Cable

Before you begin, make sure to disconnect the negative battery cable to avoid electrical shocks and damage to your car’s electrical system. Locate the negative terminal on your car battery, and use a wrench or pliers to loosen the clamp. Once the cable is loose, carefully remove it from the battery terminal and secure it away from the battery.

Step 2: Remove the Dash Trim

To access the radio wiring, you’ll need to remove the dash trim that surrounds the radio. Use a trim removal tool to carefully pry off the trim, taking care not to scratch or damage the dashboard. Once the trim is removed, set it aside in a safe place.

Step 3: Remove the Factory Radio

Next, you’ll need to remove the factory radio from the dashboard. Locate the mounting screws that hold the radio in place, and use a Phillips screwdriver to remove them. Once the screws are removed, carefully pull the radio out of the dashboard and disconnect the wiring harness and antenna cable.

Step 4: Connect the Wiring Harness Adapter

Now you’ll need to connect the wiring harness adapter to the factory wiring harness. The wiring harness adapter is designed to match the color-coded wires on your new radio, so you can easily connect them without cutting or splicing any wires. Simply plug the adapter into the factory wiring harness and connect the other end to your new radio.

Frequently Asked Questions

Q: What do the colors of the wires mean?

A: The color of the wires on your Toyota 4Runner radio wiring diagram indicates their function. For example, the black wire is the ground wire, while the red wire is the power wire. The yellow wire is for the memory, and the blue wire is for the amplifier or power antenna.

Using a wiring harness adapter is the easiest and safest way to install a new radio in your 4Runner.
