Orange Wire

The orange wire is the battery (+) wire. This wire provides power to the radio at all times, even when the ignition is off. This is why the radio can still play even when the car is turned off.

You should connect the orange wire to the positive terminal on your car battery, or to a fuse that’s always hot.

Yellow Wire

The yellow wire is the ignition on (+) wire. This wire provides power to the radio when the ignition is turned on. This is why the radio turns off when you turn off the car.

You should connect the yellow wire to the ignition switch wire in your car’s wiring harness.

Black Wire

The black wire is the ground (-) wire. This wire provides a ground connection for the radio, which is necessary for it to work properly.

You should connect the black wire to a metal point on your car’s chassis.

Speaker Wires

The remaining wires in the wiring diagram are for the speakers. There are four speaker wires in total, two for each of the front speakers and two for each of the rear speakers.

The gray and gray/black wires are for the right front speaker, while the white and white/black wires are for the left front speaker. The green and green/black wires are for the left rear speaker, and the purple and purple/black wires are for the right rear speaker.

You should connect each of these wires to the corresponding wire in your car’s wiring harness.

FAQ

Q: Can I use any radio in my 1990 Chevy 1500?

A: No, you can’t. The radio in your 1990 Chevy 1500 is a unique size and shape that won’t fit most aftermarket radios. If you want to replace your radio, you’ll need to find a model that’s specifically designed to fit your car.

Q: Can I install the radio myself?

A: Yes, you can. Installing a radio in a 1990 Chevy 1500 is a fairly simple process. All you need are some basic tools, and you should be able to do it in a few hours. However, if you’re not comfortable working with electronics, you might want to have a professional do it for you.

Q: How do I know which wire is which?

A: The wiring diagram for the radio in your 1990 Chevy 1500 should tell you which wire is which. Each wire has a specific function, and the diagram will show you which wire does what. If you’re unsure, you can always consult with a professional or refer to the owner’s manual for your car.

Q: Can I use a wiring harness instead of connecting the wires directly?

A: Yes, you can. Using a wiring harness can make the installation process much easier, especially if you’re not comfortable working with electronics. A wiring harness will connect directly to your car’s wiring harness, and will come with instructions on how to connect it to your new radio.

Q: What if I want to install a subwoofer?

A: Installing a subwoofer requires a bit more work than installing a radio. You’ll need to run a new set of wires from the radio to the subwoofer, and you’ll need to install an amplifier to power the subwoofer. If you’re not comfortable with this type of work, you might want to have a professional do it for you.
