Best way to wire in a new radio to your car. Always work well.
Have used these before when I have changed out the radio in my Miata. Wires are of a good length and well labeled. Connectors work great and have lasted me for years in the past. Easy method for wiring in a new radio.

Fits and matches color code
Worked perfectly, color code matched my conversion

Works as intended, requires some rigging
Works and does its job, I wish they would provide a grounding solution in the kit for NA6 Miata’s. I have to commit atrocities instead but it works well!

Made the process of wiring in an aftermarket radio. It connected to the oem harness no issues and was easy to use at an inexpensive price. Overall the fit and easy color coding worked and made everything an amazing experience

Works perfect for 1995 Miata
Good kit and under $10. Wired up to an ATOTO double DIN head unit in a 1995 Miata. Super easy, just use the package instructions as far as which wires match up. Solder or use twist connectors and you are done. Don’t forget the grounding connection.

No issues. Worked perfectly for an aftermarket radio for my 90’ Miata. As a noob to all this, it was really straight forward: connect the same colours together (I crimped my wires using butt connectors) I did not have any rear speakers including seat headrest speakers so the spare green and violet wire connector I did not connect.

Good quality plug and play radio harness, that kept my factory connectors intact. Fit my 1991 Miata perfectly. Wires were properly labeled.

Just what I needed to facilitate radio installation without having to splice wires.

Plug and play. 1/4 the cost of buying it locally. Works just as good. Not much else I can say about this product! It worked, it saved me about $20. Thank you!
