Are you trying to install a new radio in your 2003 Mitsubishi Eclipse? A common challenge that many people face when working on cars is understanding the wiring diagram. This guide will walk you through everything you need to know about the 2003 Eclipse radio wiring diagram, and provide some helpful tips to ensure your installation goes smoothly.
Understanding the 2003 Eclipse Radio Wiring Diagram
The 2003 Eclipse radio wiring diagram can be a bit confusing if you’re not familiar with car wiring diagrams. Here are a few key things to keep in mind:
- There are two different wiring harnesses for the 2003 Eclipse – one for the base model and one for the GT model. Make sure you have the correct wiring diagram for your vehicle.
- The wiring colors may not match up exactly with your new radio’s harness. You may need to consult both diagrams and use a multimeter to identify the correct wires.
- The radio wiring diagram only shows the connections for the radio itself. There may be additional wires for other components in the vehicle, such as the speakers or amplifier.
With these things in mind, let’s take a closer look at the wiring diagram for the 2003 Eclipse radio.

FAQ
What is the best way to identify the correct wires when installing a new radio?
The easiest way to identify the correct wires is to use a wiring harness adapter. This adapter will plug into the factory wiring harness, and the other end will have the correct connections for your new radio. If you do not have a wiring harness adapter, you can use a multimeter to identify the wires. Set the multimeter to the resistance setting, and touch the probes to different wires until you find the one with low resistance. This will be the ground wire. Once you have identified the ground wire, you can use the same process to identify the other wires.
What if my new radio has a different number of wires than the factory harness?
If your new radio has fewer wires than the factory harness, you may need to splice some wires together. If your new radio has more wires than the factory harness, you may need to connect some of the wires to different components in the vehicle, such as the power antenna or steering wheel controls.
Can I install a new radio without the wiring diagram?
You can install a new radio without the wiring diagram, but it will be much more difficult. You will need to identify each wire and its function, which can be time-consuming and frustrating. The wiring diagram will make the installation process much easier and ensure that you have made the correct connections.
What if I’m still having problems with my new radio after installing it?
If you’re still having problems with your new radio after installing it, there may be an issue with the wiring or another component in the vehicle. Check all the connections to ensure they are correct and secure. If you’re still having issues, consult a professional mechanic or car audio installer.
Conclusion
The 2003 Eclipse radio wiring diagram can be a bit confusing, but with the right tools and knowledge, you can easily install a new radio in your vehicle. Make sure you have the correct wiring diagram for your vehicle, and use a wiring harness adapter if possible. If you’re not confident in your ability to install the radio yourself, consult a professional mechanic or car audio installer.
