Introduction

Before we dive into the wiring harness diagram, let’s take a moment to discuss what exactly a wiring harness is and why it’s important. In short, a wiring harness is a bundle of wires that are used to transmit electrical power and signals between different components in your vehicle. These wires are typically organized and bundled together in a way that makes installation easier and more efficient.

Having a properly installed wiring harness is critical to the performance of your 1968 radio. Without it, your radio may not work at all, or it may work intermittently, causing frustration and headaches. By following the wiring harness diagram and ensuring that each wire is connected correctly, you can avoid these issues and enjoy clear, quality sound from your radio for years to come.

Wiring Harness Diagram

The following wiring harness diagram shows the connections you need to make in order to properly wire your 1968 radio:

Wire Color Function Connection
Green Power (12V) Connected to the ignition switch
Red Antenna Connected to the antenna lead
Black Ground Connected to a clean, unpainted metal surface on the dashboard or frame
Violet Left Speaker Connected to the left speaker wire
White Right Speaker Connected to the right speaker wire

It’s important to note that the specific wire colors and functions may vary depending on the brand and model of your radio. Always consult your owner’s manual or the manufacturer’s website for the correct wiring diagram for your particular radio.

Green Wire (Power)

The green wire is responsible for supplying power to your radio. This wire should be connected to the ignition switch in your vehicle. This ensures that your radio only turns on when the ignition is in the “on” position, helping to conserve your battery and prevent unnecessary drain.

When connecting the green wire, be sure to use a high-quality connector or soldering iron. A loose or poorly connected wire can cause issues with your radio’s performance or even damage the unit itself.

Red Wire (Antenna)

The red wire is responsible for connecting your radio to your vehicle’s antenna. This wire should be connected to the antenna lead on your vehicle, typically located near the rear of the vehicle or on the roof.

When connecting the red wire, be sure to use a high-quality connector or soldering iron. A loose or poorly connected wire can cause issues with your radio’s reception or even damage the unit itself.

Black Wire (Ground)

The black wire is responsible for providing a ground connection for your radio. This wire should be connected to a clean, unpainted metal surface on either the dashboard or the frame of the vehicle.

When connecting the black wire, be sure to use a high-quality connector or soldering iron. A loose or poorly connected ground wire can cause issues with your radio’s performance or even damage the unit itself.

Violet Wire (Left Speaker)

The violet wire is responsible for connecting your radio to the left speaker in your vehicle. This wire should be connected to the corresponding wire for the left speaker.

When connecting the violet wire, be sure to use a high-quality connector or soldering iron. A loose or poorly connected speaker wire can cause issues with your radio’s sound quality or even damage the unit itself.

White Wire (Right Speaker)

The white wire is responsible for connecting your radio to the right speaker in your vehicle. This wire should be connected to the corresponding wire for the right speaker.

When connecting the white wire, be sure to use a high-quality connector or soldering iron. A loose or poorly connected speaker wire can cause issues with your radio’s sound quality or even damage the unit itself.

FAQ

Q: What if my wire colors don’t match those in the diagram?

A: It’s important to consult your owner’s manual or the manufacturer’s website for the correct wiring diagram for your particular radio. Wire colors and functions may vary depending on the brand and model of your radio.

Q: Can I connect the green wire to a constant power source instead of the ignition switch?

A: While it’s possible to connect the green wire to a constant power source, this is not recommended. Doing so can cause unnecessary drain on your vehicle’s battery and may result in your radio turning on even when the ignition switch is off.

Q: What kind of connectors should I use to connect the wires?

A: It’s recommended that you use high-quality connectors or a soldering iron to connect the wires. This ensures a secure and reliable connection that won’t come loose over time.

Q: How do I know if my wiring harness is installed correctly?

A: Once you’ve connected all the wires according to the wiring harness diagram, turn on your radio and test it out. If everything is working correctly, you should hear clear, quality sound through your speakers. If your radio is not working properly, consult your owner’s manual or the manufacturer’s website for troubleshooting tips.

Q: Can I install a new radio in my 1968 vehicle?

A: Yes, it’s possible to install a new radio in your 1968 vehicle. However, you may need to purchase an adapter or wiring harness to ensure that the new radio is compatible with your vehicle’s wiring system.

Conclusion

By following the wiring harness diagram and using high-quality connectors, you can ensure that your 1968 radio is properly installed and working like new again. If you have any questions or concerns about your wiring harness, consult your owner’s manual or the manufacturer’s website for more information.
