By | July 25, 2022



The Ford Crown Victoria has long been a staple of the automotive world, and its 2003 model year proved to be one of the most popular yet. But for those who own one of these classic vehicles and want to upgrade the radio, knowing the radio wiring diagram can be a challenge. That’s why we’re here to help.

Let’s start with the basics: What is a radio wiring diagram? It is, in essence, a map of sorts, showing how each component of your car’s electrical system is connected. From your speakers to your power cable, this diagram provides all of the information you need to properly wire your new radio into place.

For the 2003 Ford Crown Victoria, the radio wiring diagram is as follows:

Your car’s constant 12v+ power supply is located in the Ignition Switch and should be unswitched. You’ll also want to run a wire from the Fused Relay Box, so you can use it as an ACC (Accessories) source. Then, you’ll need to connect the speaker wires, the antenna cable, and the ground cable.

Overall, wiring a new radio into your 2003 Ford Crown Victoria is relatively straightforward, as long as you have a proper wiring diagram. Obviously, an inexperienced mechanic should have someone knowledgeable look over the work before turning on the car.

No matter if you’re an experienced expert or a novice, having the right wiring diagram is essential. And, now that you have all the information on wiring up your Ford Crown Victoria, there’s no excuse not to upgrade that radio to your favorite tunes.

So what are you waiting for? Get out there and get your radio wired up so you can enjoy that classic Crown Vic ride with your favorite music blasting in the background.
