Perfect match but Pay attention

This was a perfect match to our radio system. Did require a lot of tape, but made the job a lot easier. Pay attention for all the colors and then same colored with stripes. Also you will have to decide which way your system works and not use all the wires.

Go for it

A big thanks to Sonic Electronix to give it to me for free. This is a must have product if you want to install a car stereo by yourself. You don't have to be a pro to do it, all you need to do it matching the color.

HY03B

I recently mounted a new radio into my 2007 Tiburon. I figured I'd make the wiring part of the installation easier by using this adapter. It helped immensely. Since the old wires weren't color coded like this one it would have been near impossible for me without it. The colored wires simplifies things greatly but of course the crimping was still a pain. More than worth the money.

East as matching colors

This wiring adapter was a god send. Simply match up the wires on the radio to the wires on the adaptor by color and you have the speaker and electric connections done. The plug fit the cars factory wire loom perfectly. This was the easiest wiring job I have ever done.

This product is pretty self explanatory. It connects from your aftermarket radio to the factory harness. Was installed on a 04 hyundai tiburon great product.

Worked out wonderfully

Bought this to connect a new stereo to my 2005 Hyundai Sonata and it worked great. The wires are very well labeled and so it was just a matter of matching the right wires up and finding twist-crimp connectors to connect this harness to the harness for my receiver. Worked like a charm!
