What You Need To Know About Wire Color Codes?

Do you ever think that we should learn about radio wire color codes?

I never thought that until about a month ago, when my mother asked me to fix her old car radio. I did not remember precisely how I reacted but the whole process was a disaster.

The reason was I did not know which wire should be hooked up in another; or more precisely, I could not recall any of radio wire color codes. And it didn’t have a harness as well, which made the wires even more confused and everything went ultimately messed up. Therefore, it took me a half of the morning to finish the job and help my mother have brand new cables.

It was not a difficult job but truly made me realize how important we needed to remember wire color codes. And I know that many of people, including you, have not discovered why we need to know about them and what the feature of each wire is. So in this article today, I will show you the most basic things you need to know about them. If you are having any problems just like mine, I believe it would help you.

1. What are the wires color codes?

Some basic codes are approved in many countries and almost all of brands of cars and radios. I will mention about some different codes other vehicles in the next parts. For now, you won’t need to wonder if there would be any distinctions in each type.

2. Why do we need them?

We need the wire codes mostly for emergencies. My situation is one example, which I needed to repair my mother’s aftermarket radio and didn’t want to waste time searching Google. Learning the functions of each wire saved me quite a lot of money for technical guys, who never undercharge. And if you memorize them, you won’t need so much time like me to find out which wires need being connected with each other. The entire installing process would be very smooth and comfortable.

Besides, you will also know why we need different color codes if you discover a little about their origins. I guess hardly anyone knows that the wires did not have as many colors as they are now. The original ones started being used when Thomas Edison commercialized light bulbs more than a century ago, which were only made with three basic colors: Black, Gray, and Red. Radio wires were invented about 50 years after that and could not avoid being made with the same format.

Therefore, if you ever find a radio with one three colors that I have mentioned above, you should not use it. I’m sure it was made over 30 years ago and would not meet any electrical safety requirements that are set up at the present.
