Step-by-Step Guide
Before we begin, it’s important to gather all necessary materials. You will need a wiring harness adapter, wire cutters, crimping tool, and a stereo installation kit. Once you have everything ready, follow these steps:
1. Disconnect the Negative Battery Terminal
Prior to any installation or wiring, it’s important to disconnect the negative battery terminal to prevent any electrical damage or shock.

Remove the factory stereo from the dashboard. Use a stereo removal tool to pull out the unit and unplug the wiring harness and antenna cable from the back of the stereo.
3. Connect the Wiring Harness Adapter
Connect the wiring harness adapter to the original wiring harness of the vehicle. This adapter will allow you to connect your new stereo to the existing wiring without having to cut any wires.
