Installation Process
Before you start installing your new radio, make sure you have all the necessary tools on hand. You’ll need wire strippers, pliers, electrical tape, and a wiring harness adapter. Here are the steps to follow:
Step 1: Disconnect the Battery
Before you start connecting any wires, make sure to disconnect the negative cable from your battery. This will prevent any accidental shocks or short circuits while you’re working on your radio.
Step 2: Remove the Factory Radio
You’ll need to remove the factory radio from your 99 Chevy Silverado before you can start installing the new one. Use a plastic pry tool or flathead screwdriver to gently pry off the trim panel surrounding the radio. Then, remove the screws holding the radio in place and disconnect the wiring harness and antenna cable from the back of the radio.
Step 3: Connect the Wiring Harness
Your new radio should come with a wiring harness adapter that will make it easier to connect the wires. Simply match the wire colors on the adapter to the corresponding wires on your Chevy Silverado harness and use pliers to twist them together. Then, cover the connections with electrical tape to protect them.
Step 4: Connect the Antenna Cable
The antenna cable is usually a single wire with a male connector at the end. Simply plug it into the female antenna port on the back of your new radio.
Step 5: Mount the New Radio
Once you’ve connected all the wires and the antenna cable, it’s time to mount the new radio in place. Use the screws that came with the new radio to secure it to the dash, then place the trim panel back in place and snap it into position.
Step 6: Reconnect the Battery
Finally, reconnect the negative cable to your battery and turn on your new radio to make sure everything is working properly. If you hear sound coming from all speakers, you’re good to go!
Frequently Asked Questions
Q: What is the purpose of the orange wire?
The orange wire is your constant 12v+ power source. This wire provides power to your radio even when your ignition is turned off, so you don’t lose any saved settings or presets when you turn your car off.
Q: Which wire is the ground wire?
The black wire is your ground wire. This wire should be connected to a metal surface in your car, like a bolt or the car frame, to provide a solid ground connection for your radio.
Q: What is the purpose of the blue/white stripe wire?
The blue/white stripe wire is your remote amp turn-on wire. This wire allows your radio to turn on your external amplifier when your radio is turned on.
Q: Can I install the new radio without a wiring harness adapter?
It’s not recommended to install a new radio without a wiring harness adapter. The adapter makes it much easier to match the wire colors and connect them properly, and it also protects your car’s wiring harness from damage.
Q: How can I test my new radio before I finish the installation?
You can test your new radio by connecting the wiring harness adapter and antenna cable to the back of the radio, then turning on your car to see if the radio starts up and plays sound. It’s a good idea to do this before you mount the new radio in place to ensure there are no issues.
