This wiring diagram plays an essential role in ensuring that all electrical parts within the vehicle are operating properly and efficiently. With this in mind, it’s important for Mustang owners to have a comprehensive understanding of the 1989 Ford Mustang radio wiring diagram.

First, let’s take a look at the factory radio wiring setup. The main power source for the radio unit is provided from the battery via the ignition switch. A large black cable runs from the terminal on the battery to the ignition switch before branching off to the radio in order to provide power. Additionally, you’ll need to locate the 12V constant wire that comes from the starter solenoid, which gets connected directly to the battery terminal.

You’ll also need to connect the ground wire, which runs from the frame of the car to the back of the radio. Once these wires are in place, you can begin hooking up your aftermarket stereo. The wiring harness on the back of the new radio should contain several color-coded cables. The yellow and red power wires should be connected to the wiring harness using butt connectors. Next is the speaker wires. The right speakers will require the blue and green wires, while the left speakers will need the white and gray wires.
