Honda is a well-known Japanese car brand. Their cars, especially Honda Civic, are famous for cheap maintenance, mileage, and excellent resale value.

But the OEM radio is an area where they get some criticism.

If you have an older Honda car, it’ll most probably have a button-based radio with a small-sized screen and limited connectivity options.

And because newer tech features are coming into the aftermarket radios with every passing year, you have no choice but to upgrade to 3rd-party options.

There are many advanced-level single-din and double-din radios that can give you features like Apple Carplay/Android Auto, Voice commands, Touchscreen display, etc.

Once you’ve purchased a 3rd-party radio, you’ll have to find the correct color codes for your vehicle’s radio wiring. So you can match them with the new radio’s wires.

Honda Radio Wiring Color Codes

I have recently published a post about wiring color codes in Nissan radios. So, in this post, we’ll talk about wiring color codes in Honda vehicles. Needless to say, this post has covered only the popular Honda models. That’s why it may not feature your particular vehicle.

If that’s the case, you can comment below, and I’ll try to find its info and include it in this post. Or you can also go through the owner’s manual of your car. More often than not, it will have the radio wiring diagram and color codes.
